Bitcoin Transaction Fees Explained [Complete Guide] - UNHASHED

[Question] bitcoin-qt - Should I manually set a transaction fee?

I'm using the official bitcoin-qt wallet. Under the wallet tab I can manually set a transaction fee. Should I manually add a transaction fee or should I just let my wallet automatically figure it out? What would you guys recommend?
Thanks!

how to make transactions with 0 fee in bitcoin-qt? I've set 0 fee at configs and .conf file but whenever i send it sets an amount for fee.. (it's possible because blockchain.info wallet can do it)

What's an appropriate transaction fee to set in Bitcoin QT?

I had it set to 0.005, and realized that's like $3! So, what do most people keep it at? 0.0005? Or to be even stingier and set it at like 0.00005?
Would like advice on it.
Thanks.

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Particl Marketplace: Where Sellers Meet Buyers

Particl Marketplace: Where Sellers Meet Buyers
People had been speculating since the dawn of crypto when the world’s largest online marketplaces, the ones of the Amazon caliber like eBay, Etsy or AliExpress, and, well, Amazon itself, would start to accept cryptocurrencies. There were a slew of rumors, opinions, and theories thickly interspersed with false reports popping up here and there of Amazon and its little cousins being on the verge of embracing cryptocurrencies. On top of that, someone has actually posted a petition on change.org to add Ether to Amazon as a payment method.
by StealthEX
Long story short, that was a waste of time. High hopes fell flat, and people lost religion. But not all. As the common wisdom goes, when hope dies, action begins. This exposition describes one such effort which tries to bring to fruition the idea of a decentralized marketplace for trading goods and services. And as you might have already figured it out, with a cryptocurrency as a means of payment. So let’s welcome Particl Marketplace and see what it has to offer – and what Amazon has missed.

What is it, in simple words?

Particl Marketplace is an online marketplace where you can trade goods and services. Not a big deal, you may think. However, what distinguishes it from places like Amazon as well as cryptocurrency-enabled marketplaces is the decentralized nature of purchases on Particl. You can think of it as a variety of a decentralized cryptocurrency exchange (aka DEX) where trades are being conducted on-chain. But in case of Particl, it is goods and services that are being traded, not fiat or crypto, with deals on-chain as well, fully encrypted and decentralized.
Particl is a global peer-to-peer privacy-centered marketplace that uses an automated two-party escrow system. It is crypto-agnostic and designed to work with any cryptocurrency, creating a secure, highly-scalable environment supported by a privacy-focused blockchain-based platform. The team behind the project sees its mission in developing “a new decentralized, private and democratic economy” that is governed by the network of its users, with no central authority or middleman getting in the way.
In the project developers’ own words, Particl enables everyone to participate in a free, anonymous exchange of all kinds of goods, without paying any fee and regardless of geographical location. To be sure, you are already thinking about Silk Road and its dark fate, and that the government is going to crack down monumentally on Particl one day. Well, the outcome may vary as the payments on the platform are made using its own cryptocurrency PART, with its laser focus on privacy and anonymity. But more on this later.

How did it grow up?

The development of the Particl project started in early 2017 with the release of the white paper describing the team’s vision for the marketplace, which was shortly followed by a successful seed funding that brought in enough funds ($750,000) to support the development of the project for a year (it turned out sufficient to last for over two years).
These donations helped to establish the Particl Foundation, a non-profit Swiss organization with the goal of providing legal protection for the project to ensure its sustained development and compliance with government regulations. It receives 10% of all the staking rewards generated on the Particl network, making the project self-sustainable and free for most uses.
Unlike other such projects in the crypto arena, Particl has been using its own blockchain from day one, which happened to be July 17, 2017. It was specifically designed to be crypto agnostic by supporting and working with any cryptocurrency. Additionally, it supported the smart contract tech out of the box, giving users an ability to build all kinds of decentralized applications (dApps) that can be directly integrated into the Particl marketplace.
On May 31, 2018, the Particl Marketplace, the Holy Grail of the entire endeavor, was made available for alpha testing on the testnet of the project, which later split into development and stable branches. It went live with the mainnet release of the Particl Open Marketplace on August 12, 2019, which featured Particl Desktop 2.0.0, a client-side application providing user interface and built-in wallet functions.
On November 25, 2019, the Particl Desktop 2.3.0 client was released that enabled Bitcoin payments and marked the introduction of untraceable transactions. With the help of the new in-wallet exchange module, everyone can easily swap their bitcoins for the native PART coin. Moreover, the module allows seamless integration of third-party accountless exchange services right into the marketplace, with StealthEX being one of them.

How is it different from other marketplaces?

The common solution many P2P marketplaces implement to protect buyers and sellers from the other party failing to honor their end of the bargain is through third-party escrow, where the “third-party” in the majority of places and cases is the platform itself that the market participants must mutually trust. In short, it is a single point of failure. And the selling (pardon the pun) point of the entire Particl’s marketplace is its decentralized escrow, which is a thing entirely between the two parties engaged. No middlemen allowed here!
And these are not empty words. Particl implements the concept best known as Mutually Assured Destruction (aptly shortened as MAD), a military doctrine you are certainly familiar with, and probably even afraid of, that consists in a mutual destruction of two belligerent parties in an all-out nuclear holocaust. If you are curious, the idea stems from the game theory and has a lot to do with the Nash Equilibrium, of John Nash’s fame. In a nutshell, Particl removes the need for a trusted escrow agent by introducing MAD escrow smart contracts.
A MAD escrow contract allows to lock funds in a multi-signature address that can be released only if all the parties sign off on the transaction. So both the seller and the buyer lock in the contract an agreed amount for a specified period of time, with the buyer also depositing the payment for the items purchased. The escrowed funds are released when both parties confirm the fulfillment of the agreement. Should one party break the terms, the funds remain locked for good causing a mutual financial loss until both parties agree to sign off.
Another crucial aspect of Particl Marketplace is its end-to-end privacy. The problem with conventional marketplaces acting as an escrow agent is that the communication between the parties should be open to the agent for it to serve as an arbitrator. With Particl, it is no longer required, and all messages between the buyer and the seller are encrypted. Despite being public, only their recipient can decrypt them, which effectively makes messages untraceable.
This is also where the PART coin turns up quite handy. It enables three different privacy modes, and with the most secure mode, the Anon mode, PART transactions utilize the RingCT privacy protocol, which hides both the amount transferred and the identity of the parties transacting. Accordingly, every part of the entire Particl trading environment is thoroughly decentralized, and the full anonymity of market participants is maintained at all times, making the platform a completely trustless marketplace. Big Brother is no longer watching you.
Aside from that, you can stake PART and generate a source of passive income for yourself. Particl uses a custom Proof-of-Stake consensus protocol, allowing you to get a piece of the pie in the form of new coins created at each block according to the scheduled inflation process. The annual inflation rate is initially set to 5% and goes down 1 percentage point every year until it finally floors at 2% indefinitely. Moreover, these rates are a bare minimum as they assume that all PART coins have been staked. Otherwise, the income will be bigger and better as the same rewards are paid to fewer coins.
Additionally, your passive income through staking PART will be augmented by the fees generated through the everyday marketplace operations. Whether it is network fees collected via PART transactions or marketplace listing fees paid by the sellers, all of them contribute to the stakers’ rewards. At the end of the day, staking PART can turn into a profitable business once the Particl platform starts to attract more traffic. In simple words, the more popular the market gets, the more fees it generates, the more coins the stakers earn.
As PART is a standalone cryptocurrency, it can be used outside Particl Marketplace as well. So if you plan on using it for purposes other than eCommerce, it is traded on several exchanges, for example, HitBTC and Bittrex, with more exchanges to list PART in the future. There are native Particl wallets available for storing PART such as Particl Qt with Ledger support, Particl-cli, and Particl Copay Wallet, with the latter available for both the desktop and the mobile. There is also a third-party multicurrency Flare Wallet, enabling cold staking for Particl.
Running Particl is a collective effort, which means no operational costs and no company bagging profits from it. The marketplace buyers don’t pay any commissions other than tiny network confirmation fees, while the sellers are only charged a small listing fee to keep spam listings to a minimum. This creates a highly competitive environment, with the sellers making more profits and the buyers having access to cheaper goods and services as a result.

What’s in the pipeline?

The next major release of the Particl Marketplace should have been Particl Desktop 2.4.0, but it was later rebranded as Particl Desktop 3.0 to reflect its breakthrough nature. It is set for release in the second half of 2020 and will enable the addition of user-created markets and storefronts, effectively turning the Particl marketplace into a network of specialized markets.
And if you think about it, that makes perfect sense. Say, you have a social network account highly merited and full of karma that you want to sell, whatever your reasons might be. Then creating a dedicated market for trading such accounts privately and securely may look extremely appealing to you. Whether it is the right thing to do is another matter, of course.
Kidding aside, it is obviously not about selling or offering something that the society on the whole doesn’t approve of or frowns upon. If you are a freelancer, for example, a graphics designer or a translator, you would be certainly interested in the future freelancer markets – along with your potential employers. Put simply, birds of a feather should flock together.
To keep things in perspective, popular freelancer markets that exist today charge up to 10-20% of what you would get from your client if you negotiated directly. All in all, establishing communities across the marketplace seems to be the next logical step in the natural evolution and growth of the platform. In fact, it is a little surprising that the Particl team didn’t come up with this idea earlier.
Meanwhile, we wish Particl success and good luck in achieving their goals and aspirations.

How-to: setup your multisignature Cold wallet in Bitcoin Core 0.20 (highest security setup)

Last release of Core is amazing !
The main new feature is sortedmulti descriptor. This allows you to import your multisig setup in Core almost as if it was Electrum when combine to the new PSBT export in GUI !
As it needs command line and some weird checksum, you also need to input very long command in the console and if you made a mistake, you cannot copy the last command you made. So take your time when the commands are long to check everything and don't miss anything, use copy paste before validating the long command. You only have to do this once fortunately :)
I detail here how you do it with a k of n setup, good luck:
And you are DONE ! You should get the exact same addresses than Electrum and you can created receiving addresses in Qt ! To send money, just go to the send section, use the new coin control feature and export a partially signed transaction. You can use HWI or Electrum to sign it with your hardware wallets !
Notice: You can import more or less than 2000 addresses of each type. If less, blockchain rescan is faster but you may need to redo what we have done here later when all addresses will have been used once. If more, it is the contrary.

You now have the most possibly secure setup in one software: multisig with hardware on the full node wallet. When Bitcoin Core 0.21.0 will be out, we will also have native descriptor wallet so maybe we will have HD version of this. But for now, this is the best you can do ! Enjoy :)

P.S. : if you like doing things in one shot you can do the last two steps in one big command: importmulti '[{"desc": "wsh(sortedmulti(k,[path1]xpub1.../0/*,[path2]xpub2.../0/*,...,[pathn]xpubn/0/*))#check_sum0", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "keypool": true}, {"desc": "wsh(sortedmulti(k,[path1]xpub1.../1/*,[path2]xpub2.../1/*,...,[pathn]xpubn/1/*))#check_sum1", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "internal": true}]'

Interesting change allowing for "Reciever pays" TXN fees.

I'm excited about a new change in bitcoin-qt v20.0 (unreleased) allowing for the propagation of zero fee (0 sat/b) TXNs. Previously this was nerfed by the minRelayTxFee requirement. This would allow the receiver to set the fees (indirectly) by simply chaining a CPFP TXN to the end of it. Might work something like this.
  1. You place a bet at a BTC betting site.
  2. If you win, the payout is a raw TXN hex string.
  3. You broadcast the raw TXN along with a second "child" that pays the fee.
  4. Betting site is now no longer paying fees on winning bets.
Could offer a lot of solutions to exchanges that require a "withdraw fee" claiming that they need to pay the miners. This would allow users to request a zero-fee raw-hex withdraw transaction allowing the user to pay the fees themselves.
For the more technical user this would offer up a lot of neat possiblities.

How To Stake/Mine Coinevo

EVO Staking/Evo mining

Evo uses Proof of Stake consensus mechanism, which is different from Bitcoin's PoW (Proof of Work). Evo mining process in PoS system is called staking. The block producer will get 6.5EVO, as well as the transaction fees and gases as block reward. So the real reward is usually more than 6.5 evo in total.
Basic requirements for staking:
  1. Run a Coinevo fullnode, and keep online (Since Coinevo is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);
  2. Have some EVO in the wallet (fullnode)(Any amount of EVO can be used for staking, more EVO means higher possibility to stake).
If you have no EVO yet, please get some from market before you doing following staking settings.
Currently, Coinevo Core wallet is the only wallet that support Coinevo PoS staking. Note that other wallets like mobile wallet and Evo Electrum are not able to stake for the time being.
Two ways to stake:
Either way works in the same way for staking, so you can choose either method you like.

Method 1:Staking with evod (command line)

1. Run evod

Follow the guidance to run evod :
./evod -daemon 
Staking is default on for evod, so no need for other options if you only want to stake.

2. Send some EVO to your wallet

First you can generate a new address with:
./evo-cli getnewaddress 
This will generate a new address with Prefix '1'. You can send some EVO to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary EVO as you like for staking.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..
After the EVO node syncing to the latest block, you can check current balance with ./evo-cli getbalance or get utxo list with./evo-cli listunspent
Please do following steps after your coin is mature.

3. Check staking info

Check current staking info with:
./evo-cli getstakinginfo 
You might get the result like this:
{ "enabled": true, "staking": true, "errors": "", "currentblocktx": 0, "pooledtx": 0, "difficulty": 3693409.779133397, "search-interval": 1577, "weight": 309584575558555, "netstakeweight": 1948540143266404, "expectedtime": 805 } 
enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of EVO that is staking right now, with unit 10^-8EVO, here in the example, we have 0.532EVO staking. expectedtime stands for the expected time that you will get a reward, the unit is second.

4. How to stake if the wallet is encrypted?

If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet.
Coinevo wallet can be encrypted with encryptwallet . However, staking will be stopped when it is encrypted. For example, ./evo-cli getstakinginfo for a encrypted wallet:
{ "enabled": true, "staking": false, "errors": "", "currentblocksize": 1000, "currentblocktx": 0, "pooledtx": 94, "difficulty": 5788429.670171153, "search-interval": 0, "weight": 53206430, "netstakeweight": 2438496688951881, "expectedtime": 0 } 
See staking turns to false , which means wallet is not staking.
You can use walletpassphrase to unlock wallet for staking:
./evo-cli walletpassphrase "" 99999999 true 
After unlocking, you can double check getstakinginfo , it should look the same with previous unlocked result, staking become true.

Method 2: Staking with evo-qt wallet (official PC wallet)

Current supported platform: Mac/Linux/Windows.

1. Open Evo qt wallet

Launch the wallet.

2. Send some EVO to your wallet

If you already have some EVO in your wallet, you might skip this step.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..

3. Check staking status

The flash sign at the bottom of wallet shows staking info :
Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:
Hollow flash measn it is not staking
Possible reasons for not staking:
No flash sign means staking is disabled

About block reward

The block producer will get more than 6.5 EVO rewards, something to keep in mind:

How to disable staking?

Staking is by default enabled for Coinevo wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below:
1 Add -staking=false when running Coinevo node:
./evod -staking=false -daemon 
For qt wallet, it is like:
./evo-qt -staking=false 
2 Add config staking=false in evo.conf;
3 Encrypt wallet, since encrypted wallet will automatically stop staking.

What's the deal with transaction fees? Given that Bitcoins are now worth so much more than they used to be, is 0.0005 still appropriate?

I sent my buddy €5 in the form of BTC today so he could pick me up a sandwich down the street. Only later did I realise that I actually spend roughly €5.05 in the process. Granted, it's only 5cents, but in the long run, with a number of smallish transactions, that does seem like an awful lot -- especially if we expect to see Bitcoin excel in microtransactions.
TL;DR: Is the 0.005BTC fee still considered reasonable, given that the real value of bitcoins is increasing so rapidly?

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

[Lightning] I didn't believe it until I saw it

Moderately long post, tl;dr at the bottom.
I've seen lightning transaction gifs and videos over and over. Today, I decided to fire up a lightning node on my laptop and give it a shot.
I followed this walk-through for mac (I adapted it to Arch Linux) for setting up Bitcoin TestNet Node with Eclair Lightning (it's practically the same as Mac, except for the installation process). Running on Arch caused the problem of accidentally installing the latest dev version of Bitcoin Core (AUR:bitcoin-git) - also had some compilation issues because upstream moved some files and this hadn't been updated in the PKGBUILD.
The latest dev version of Bitcoin Core included the SegWit address generation by default, which was very nice, didn't have any bugs using it in the brief period I used it.
After a couple of hours of syncing the TestNet blocks on my laptop, I started up Eclair and got Eclair and Bitcoin Core connected (had to use bitcoin-qt --deprecatedrpc=addwitnessaddressbecuase Eclair calls a soon-to-be deprecated function), sent myself some tBTC, and started opening up channels. Once I had about 3 channels open, I went to everyone's favorite online coffee shop and rewarded myself with some imaginary coffee.
My mind was absolutely blown at how fast the transaction went through and how insanely low the fees were (10 sat).
I went to test a transaction with a couple more hops, bought myself an imaginary 100eur Steam voucher, paid 100 sat in fees, near instant transaction (my Eclair client took a couple seconds to find a route to bitrefill)
Lightning truly is an incredible addition to Bitcoin, big things are coming.
tl;dr - Saw a couple lightning transaction videos and gifs, didn't really sink in how amazing this really is, decided to give it a shot on linux, mind=blown
Edit: I've done a little further testing and noticed that Eclair doesn't warn you if you're opening a duplicate channel (open a second channel with the same node)

My thoughts

There has been too much negativity and FUD recently, so I thought I'd share some of my own thoughts.
Colin and I have been friends since 2016. We're both skilled and sought after developers within our respective spheres of influence. Colin used to float the idea of me helping him with things related to his cryptocurrency project since probably the first week we met. I'll be honest: at the time I thought it was just a cute pet project of his and — while really intellectually intriguing for me — I had very little available bandwidth to take on another project as the leader of my own small team within a startup. RaiBlocks, as it was known at the time, continued to be something on my “when I have free time” list.
That was until early December 2017. Now, many of you might associate that month with the astronomical growth of the “price” but to me it represents something completely different. I had discussed with Colin almost a year prior outlandish ideas I had for an “index fund” of cryptocurrencies that I had begun to explore. It was to be a completely automated, managed solution for people interested in cryptocurrencies without the time to commit to researching the market themselves. To support a friend, I asked Colin if I could buy some RaiBlocks from him directly to add to a test fund I was starting. Unbeknownst to me at the same time, Bitcoin transactions were taking hours and fees were approaching $20 per transaction for the kind of transactions I was attempting. That was simply unacceptable for the business model I was attempting to target. Before Colin could type out “sent” it was in my account.
It was at that moment I realised: Why isn't literally everybody using RaiBlocks for arbitrage? Why would anybody use any crypto other than RaiBlocks for everyday transactions? Why isn't every goddamn crypto news site talking about how RaiBlocks turns the entire industry on its head!?
The next day I asked Colin what I could do for the team.
Let me set the stage for you: RaiBlocks, one wallet (the Qt wallet), the old website (raiblocks.net), and the old Reddit (/raiblocks). That was the entirety of the RaiBlocks community at the time. When Colin and I originally began brainstorming where I could insert myself to benefit the community the most, Colin was adamant that the most important thing was for there to be a more user-friendly wallet. Remember, this was before anything else existed other than the Qt wallet. It was with that direction that I set off to create a more user-friendly alternative to the Qt wallet in January.
Despite some hiccups, within six months the team was able to develop and launch three completely separate codebases for three completely different platforms while working on a myriad of other things at the same time. Some people are dissatisfied with these wallets — which is fine. YOU HAVE CHOICE.
Nano now has 6+ high-quality wallets available TODAY. Take your pick! How many projects even have more than one wallet? There are some projects with a higher market cap than Nano with no wallet! Speaking of market cap...
https://i.imgur.com/ZHJQult.png
Do you think Nano's market cap deserves to be at least as big as Dogecoin's market cap? Do you believe it deserves to be beneath Bitcoin Diamond? Beneath Verge!? If not, then you should feel confident that the market is just completely bonkers right now.
There is no other project out there right now with the unique qualities of Nano or the caliber of our team. I truly believe that or I wouldn't be doing this. I also controversially believe there's only a small handful of cryptocurrencies that even have a real world use case or a reason to exist and Nano is one of them, but I digress...
Ask yourself: what exists today? I'm not interested in what's being planned or might exist in the future I'm asking what exists now? What can I use TODAY?
I need Nano to succeed because of what I can build on it, not because of what I can sell it for.
If you believe in the technology, the team, the community and what we can accomplish together then don't let FUD rule your life.
My opinions do not necessarily represent the views or positions of the Nano Core Team, the Nano Foundation or Nano Wallet Company and are solely and entirely my own.

Beginners guide to Syscoin (SYS) and why you should be investing in this cryptocurrency in 2018

What is Syscoin?

Some have described Syscoin (SYS) as the Shopify, Amazon and Ebay of the blockchain world. Syscoin is a revolutionary cryptocurrency that offers near zero cost financial transactions, incredible speed and provides businesses the infrastructure to trade goods, assets, digital certificates and data securely. Syscoin isn’t just about money and trading, it has the ability to attract various business types thanks to its native set of features geared towards business on the blockchain. From eBay traders and High Street shops to Medical applications, Insurance and Gaming, Syscoin’s decentralized network benefits everyone!
Syscoin is developed by Blockchain Foundry (BF). BF provides blockchain technology based services, projects and products for a wide variety of use cases with the stated aim of disrupting markets by leveraging the potential of blockchain technology. Syscoin is mainly known to be the first cryptocurrency to offer a fully decentralized marketplace based on blockchain. What is lesser known is that this is only a part of what Syscoin offers.
With the introduction of Masternodes in February or March 2018 SYS will be transformed from just a ’marketplace coin’ to a completely ‘utilitarian coin’. The Masternode infrastructure allows the addition of decentralized databases and file storage, increased transaction speed to surpass POS/Visa/Mastercard capabilities, true Turing complete smart contract capabilities for unlimited business logic, sidechains, application layers and an identity layer. This will all be accessible through an API, rather than a new language, enabling nearly any developer to create any blockchain application they can conceive. This will usher in the next generation of blockchain applications - made for new or existing businesses - by conveniently offering everything available from the blockchain space today.

SYS Origin

The blockchain as conceptualized by Satoshi Nakamoto back in 2008 envisioned a peer-to-peer electronic cash network that would prevent double-spending. A year later, the blockchain became an integral part of bitcoin, serving as the latter's public ledger of transactions. Although Nakamoto's reference client mentioned a decentralized marketplace service, the subsequent implementation did not incorporate this due to a lack of resources.
Syscoin was initially described in a 2014 draft whitepaper that envisioned Decentralized Marketplace Creation, Decentralized Smart Contracts and Documents, Decentralized Certificate Issuance and Transfer, and Decentralized Data Storage and Retrieval, as among the services that it would offer upon its release.
Syscoin aimed to bring Nakamoto's vision of a decentralized marketplace back into the blockchain, among the other commercial-grade services it aims to deliver to clients. Other services that Syscoin plans to provide include secure data storage and transfer, and unique user aliases that link their owners to the services controlled by the alias.
The early Syscoin wallet was superseded by the release of Blockmarket Desktop 1.0 on September 12, 2017, marking the culmination of Syscoin's vision of a fully decentralized marketplace with a desktop GUI based on the blockchain.
The planned release of Blockmarket Web, a fully web-based version, and Blockmarket Professional in 2018 takes that vision one step further, as more advanced seller stores become a reality.

The Team

The Team that NEVER quits! Before the launch of Syscoin (Q3 2014), there was a presale ICO by Moolah (as a partner), which turned out to be detrimental for Syscoin. The project raised around 1,000BTC for development but the Syscoin Team only managed to access 250BTC which were used for price support. Moolah (Ryan Kennedy) absconded with the bulk of the ICO funds and the Syscoin team were left with ~30million Syscoin at a price around 400 satoshi. Even after this tragic event, the devs didn’t quit and continued to work on the project without stopping. The case against Moolah is still on-going. See the article from CoinDesk here: http://www.coindesk.com/uk-court-syscoin-injunction-moolah-750-btc/.
What is this detail telling us about the dev team? While some crypto projects are just scams and bring little to no innovation, they’ve proven that they are in it for the long term - ably demonstrated by the fact that they continued to work despite their funds being stolen. And now that hard work is beginning to pay off with the entire team going full-time for the first time in January 2018 and new developers being hired following VC funding for BF.

What is Blockmarket Desktop?

Building on the World's First Decentralized Marketplace, Blockmarket is the newest generation of Syscoin's Desktop wallet with a complete, state-of-the-art marketplace built-in where you can securely and reliably buy and sell any items you wish. Entire stores can be created directly through the marketplace where you can sell your own products or re-sell others’ products for commission. Use of blockchain technology eliminates middlemen, credit card fees, maintenance fees, downtime and political interference. Persons are literally able to buy or sell anything to anyone, anytime, anywhere on Earth! Blockmarket Desktop was launched on September 12, 2017.

Key Blockmarket Features

• Price Pegging to currencies such as USD, EUR, GBP, CAD, CNY and BTC
• Bitcoin and Zcash as payment options
• Arbitrated Escrow
• Encrypted Messaging
• KYC/AML Compliance
• Images
• Unlimited Inventory Items

Name Aliases

Wallet addresses for cryptocurrencies generally consist of a unique string of between 27-34 alphanumeric characters. Such an address isn’t easy to memorize. Although the addresses can be added to an address book within the wallet, Syscoin has taken the user's convenience one step further, allowing you to create a unique Alias for your wallet address, such as a name, title, or characters specific to a username. These can be used to send SYS from home, to a mobile wallet, to work, to friends, to common suppliers or to repeat customers easily, without requiring any memorizing, writing it down, copy & pasting or emailing yourself the address.

Digital Certificates

Using the cryptography of the blockchain persons can issue, authorize, and exchange digital certificates of any kind. With Syscoin anyone can issue provably-unique certificates with text or ASCII content to one or multiple parties on the Syscoin blockchain. These certificates can be authenticated by anyone via Syscoin’s cryptographic proof of work. This allows for the creation and free exchange of any kind of digital asset such as ownership certificates, warranties, receipts, tickets, certifications, diplomas, software licenses and more.

Integrated Exchanges

Integrated Crypto exchanges - Flypme and Changelly will facilitate exchanging 30+ cryptos for SYS, directly within the Blockmarket wallet.

Security Audit Verified

Blockmarket was successfully and independently security audited by Digital Boundary Group and was deemed low risk. Audit Results: [https://medium.com/@BlockchainFoundry/blockmarket-security-audit-results-and-next-steps-f69f94f149bf]

Blockmarket Web – (The Key to Mass Adoption)

BM web will bring SYS’s existing decentralized marketplace and all its features into a web-based version, enabling ease of use with a simple email and password login (grandma friendly) without any need for downloading a wallet or waiting for sync. Blockmarket web will be launched in February 2018.

Key Syscoin Developments

Masternodes

Ability for world-class transactions-per-second performance to scale-out with added nodes (theoretically 100k TPS per 1000 Masternodes, 300k TPS/3k masternodes, etc). In later releases, masternodes will also process smart contracts and facilitate sharded+encrypted offchain file-storage (with onchain anchors), among other touted functionality. They should also result in steadying the price movements - less volatility as holding will be incentivized

Smart Contracts

Scalable Ethereum Virtual Machine: Allows Turing complete smart contracts to be executed following the ethereum protocol at a much faster speed and at a fraction of the ethereum gas price.

Assets & Token Issuance

With its token issuance service, Syscoin allows anyone to create a custom asset token which can then be sent directly to anyone else on the network. This facilitates a variety of use cases including ICO token issuance, supply chain management, reward points, and loyalty programs.

Anonymous Transactions

Anonymous transactions: via mixing/shuffling at user-specified denomination. Afterwards, additional tech will be added in the near future which will further compound the degree of anonymity provided -Add ValueShuffle running on top of the masternode layer and you have the world's most advanced privacy tech in any coin. This brings true money fungibility to Syscoin and the missing link for true economic sovereignty. https://twitter.com/realSidhuJag/status/948588279540035584

Instant Send

Transactions can be sent and received instantly. This represents a similar sending capability as Dash, but is a step beyond- A type of backend node locking will allow an instantly received sum to be sent immediately, without delay, and without network risk of double-spend.

[ELI5] How to send coins using Coinb.in

How to send coins from ANY wallet using https://coinb.in/#settings

Why?

Because cold wallets, such as those stored offline in a text file as I keep recommending in my standard advice below:
All you need is a text file to put your wallets in, like this example from https://walletgenerator.net/?currency=Dogecoin
1,"D7WBUpdgLRtG6WyPsqjhaKiJR65X8ZGnkZ","6KieLMW1poAzNVnmLuQZqA262gxEQ51eLGdDK8e2GL2B4LHCKKb" 2,"DM8LT16d49zHr8ByXbUwZb9UBXDGMaZRdc","6Ktgxdv6vN9v2bDHwcJBBb3oMRAgXJumESzBnxaXUSGFZoq6pWQ" 3,"D5UCa51AfxjtVHQ46oYXe2YfkctTeLXPhx","6L2WSPWadRYCwt2L1CxH6zC7PoTYY3KyjxdiUoCqi5eyq6hQKvj"
Use https://coinb.in/#settings to move coins. Download both sites and run them offline. Use https://bitinfocharts.com/dogecoin/ to check balances and transactions. See http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/ for coinb.in tutorial. And read the ELI5s (and my history) for more info.
Are without doubt THE SAFEST way to store your coins. Plus, they consume no resources. No bandwidth, no network stress for every node we have, no storage of 20Gb+ blockchains, no weeks of waiting for things to sync, no tearing your hair out and posting desperate pleas for help, and most importantly, no coins irretrievably lost because you or your client screwed up.

What?

Wallets, ALL WALLETS are nothing but numbers. Very large numbers, but fundamentally no different from “7”, “42”, “911” or a phone number. They cannot be created nor destroyed, and you either know them or you don’t. Anyone who knows a key can use it to spend any coins it controls. Anyone who doesn’t know it, can’t. Don’t be the guy who doesn’t know his own keys. Keep them safe. Make copies. Keep those safe. Don’t let your friends, kid brother or random burglar find them, but don’t lose them either.
The only other thing you need for a fully functional wallet is a way to spend coins. Coinb.in is such a way. There are others, such as DogeCoinMultiSig.org which tomcarbon built.
Oh, and you can and should download it and run it locally.

Where?

The default entry point for coinb.in is https://coinb.in/#settings because this settings page is very well hidden. Its in the tiny gear wheel on the Broadcast page.
Looking across the top of the page, you can see
  • + New
  • Verify
  • Sign
  • Broadcast
  • Wallet
  • About
We’re only going to use three of these. New, Sign, Broadcast.
Now, keep in mind that coinb.in is an old Bitcoin tool which tomcarbon added Dogecoin to. Sometimes it thinks its dealing with Bitcoin still, so if you see anything odd, go and make sure you’ve selected Dogecoin in the Settings page.

When?

This tool should be the only place you spend coins. Sure, some clients may look more convenient, but they all suffer from a very big coin-losing flaw. Whenever you split a UTXO, they create a new wallet to send the change to. And they DON’T TELL YOU! This means unless you back up after every transaction, you run a high risk of finding all your coins have ‘disappeared’ from your wallet, and you don’t recognise where they went.
So if you use a client for the convenience as well as a text list of your wallets, you won’t know to add a new wallet to your masterfile. Its best to ditch the clients entirely.

How?

Now we come to the nitty-gritty. Lets use those three wallets above and assume that #1 is the source, #2 the destination and #3 the change wallet. Note that these won’t actually work, as none of them have ever been used, but they will do as examples.
New Transaction
Located at the bottom of the New menu, this will give you a page to enter your wallets and amounts.
In the top field, you enter your source address or Key. If you use the key, it will calculate the address when you click the Load button, which should match what you expected. Note that Load only brings in the first 100 UTXOs. This is so that you can retrieve coins from high-volume wallets which would kill any client. Coinb.in is in fact the ONLY WAY to do this, as even QT falls over around 600 UTXOs.
You will see the total balance that was loaded in the Transaction Fee field. And also in the Inputs tab, where you can go to adjust which UTXOs to spend.
Now you need to add the wallet(s) and amounts to send to them. Lets suppose the source contained a single UTXO for 1,000 Doge. You want to send 500 of them. So you would enter the #2 address in the Address field, and 500 in the Amount field. The Fee now changes to 500, which is not what you want.
So you click the + button to bring up a new line, enter the change address and the other 500, making the fee zero.
And you’re done. Check that the Fee is indeed zero. Check that the amounts shown in the Outputs and Inputs tabs match exactly.

THIS IS CRITICAL!

There is a bug which will send all the coins to the miners if the Outputs exceed the Inputs. I would have expected the Fee to show as negative in such a situation, but it doesn’t. BE WARNED!
Once everything looks right, hit the Submit button.
This will give you a block of hex code. Copy it.
Sign
Go to the Sign tab and paste it. Add your private key for the source wallet and click Submit. Note this can be done offline for safety.
This will give you another block of hex, the SIGNED transaction.
Broadcast
Copy this and paste it in the Broadcast tab and click Submit.
That’s it. Your coins are on their way. Make a cuppa and settle in while they arrive in a minute or three.
Note: All fields retain their values unless you refresh the page! This can be a boon when doing multiple transactions, such as when emptying a huge wallet. But it can also be a trap for the unsuspecting. Refresh or close the window when you’re done.

Who?

Who should use this?
Absolutely EVERYONE!
Even if you’re wedded to your client in some satanic blood-contract, you should still know how this works, because sooner or later you’re going to have a problem you can’t fix without it.
Definitely download the site and store it on every device you have. On every USB backup of your wallets. On your phone (well, except iOS which doesn’t do local HTML), etc, etc, etc.
Oh, and if you’re a programmer SmartyShibe, do consider improving the code over on GitHub.

All About Zcoin

All About Zcoin

https://preview.redd.it/hixbz9f3lxm31.jpg?width=1200&format=pjpg&auto=webp&s=43896de84a3693d840c84057c0314af71718f0a3
What is Zcoin?
Zcoin, also referred to as XZC or Zerocoin, is an open source decentralized cryptocurrency that provides privacy and anonymity for its users when making transactions.
To achieve its privacy and anonymity, Zcoin uses zero-knowledge proofs via the Zerocoin protocol, which is at this moment in time one of the most cited cryptography papers.
According to Wikipedia, in cryptography, a zero-knowledge proof or zero-knowledge protocol is a method in which one party proves to another party (the verifier) that a given statement is actually true.
In other words, in a transaction with Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default, leaving you vulnerable. All it takes is one link to your personal information or IP to find out the origin of the coins.
However, when you trade with Zcoin’s Zercoin feature, your transaction history is not linked to the actual coins. Only the receiver and sender know that the funds have actually been exchanged.

How Does Zcoin Work?

Zcoin works on the Zerocoin protocol by enforcing Zero-knowledge proofs. Here are the components of Zcoin to explain how it works.
Mint: When sending a private transaction with Zcoin, all you need to do is select the number of coins you want to mint. Post that your normal Zcoin balance would reduce automatically and you will be credited with new coins and no transaction history. In essence, your old coins are burned cryptographically, which prevents anyone else from using them again and being directed to your transaction history. You get credited with new coins with no history, while the total supply is maintained.
For now, you can only mint in denominations of 1, 10, 25, 50 and 100. If you choose ‘100’ coins to be minted, for instance, you will instantly be credited with 100 new Zcoins with no history attached to them.
  • Spend: When you want to make a private transaction, you will be required to use these ‘100’ newly minted coins. From this pool of funds, you can now send any amount in any denomination to anyone anonymously because no history is attached to it.
  • Repeat: You can ‘mint’ and ‘send’ Zcoins any number of times at anytime with your privacy intact.

Zcoin’s Vision

Zcoin seeks to improve things that Bitcoin hasn’t been able to so far, some of which include fungibility, privacy and miner’s centralization.
Users of Zcoin can enjoy full fungibility and privacy along with demolishing miner’s centralization by implementing a better proof of work algorithm called MTP.
Total Zcoin supply
Only 21 million units of Zcoin will ever be produced. Currently, there are about 3.4 million units in circulation, with the rest yet to be mined.
But the total supply has increased by 388450 XZC units after a Zcoin code bug, which the team refused to roll back due to economic reasons, which is why the total supply stands at approximately 21.4 million.
Every 10 minutes, a Zcoin block is mined and 50 coins are generated, making 72,000 Zcoins per day.
Market cap of Zcoin
According to CoinMarketCap, the total circulating supply of Zcoin is 5,757,841 XZC and the current unit price is $9.6. That makes the market cap approximately $55 million*.*

Zcash:
Zcash is a decentralized and open-source peer-to-peer cryptocurrency that provides strong privacy protections. It was created as a fork of Bitcoin and, like bitcoin, it also has a hard limit of 21 million coins. Unlike bitcoin, however, Zcash offers total privacy for its users maintaining the absolute anonymity behind each transaction along with the parties and the amounts involved in it.
PIVX:
PIVX, which stands for Private Instant Verified Transaction, is an open-source, decentralized form of digital online money that uses blockchain technology. This makes it easy to transfer all around the world in an instant with low transaction fees with market leading security & privacy. PIVX focuses on privacy, security, anonymity, and instant transactions.
Monero:
Monero is a fast, private, secure and untraceable digital currency system that uses a special kind of cryptography to keep all its transactions 100% unlinkable and untraceable. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity.
Some Zcoin misconceptions
There are some misconceptions regarding Zcoin:
  • Some believe that, since Zcoin has a trusted setup that allows indefinite minting of coins, it is not safe. This is untrue. Of course, to start with they had to use a trusted setup because they have an auditable total coin supply that prevents any form of cheating. This downside however, is being taken care of by removing this trusted setup in the near future and when that happens, Zcoin will be one of the serious coins to count on for privacy.
  • Zcoin has been considered as Zcash’s fork but that is also not true because Zcash is based on the Zerocash protocol whereas Zcoin was started from scratch by applying Zerocoin tech.
Now that some of the Zcoin’s misconceptions have been cleared, here’s a look into its future.

Zcoin’s Future & Roadmap

Zcoin’s future is quite promising and worth watching based on these interesting milestones on their roadmap:
  • Zcoin is the first coin to implement MTP proof of work, which makes it possible for general masses to mine Zcoin with GPUs and CPUs. MTP doesn’t allow costly ASIC-like miners to mine XZC coins.
  • Zcoin is also implementing Znodes to make their cryptocurrency more decentralized and anonymous. These Znodes will be like masternodes and facilitate anonymous transactions as making an anonymous transaction single-handedly is quite computational.
  • Znodes will be incentivized by reducing some portion of the founder’s reward. Also, the surplus funds that get generated from the founder’s reward reduction would be used for hiring new developers and increased marketing efforts.
  • Another agenda on their roadmap is to bring inbuilt Tor or some IP obfuscation mechanism that will make it completely anonymous.
  • Apart from these, some innovative and exciting things like sigma protocol, decentralized anonymous voting and Zcoin Labs are on their roadmap, making this project worth checking out.
  • Last but not least, its recent price is a good indicator of its healthy market sentiment and shows that there are people who understand this project’s worth. Just to put things into perspective – a unit of Zcoin was priced $2 in March 2017 and now it is $37*.*

Zcoin Team & Progress

Zerocoin is a cryptocurrency proposed by professor Matthew D. Green, a professor of Johns Hopkins University, and graduate students Ian Miers and Christina Garman. It was proposed as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions.
Zerocoin was first implemented into a fully functional cryptocurrency and released to the public by Poramin Insom, the lead developer, as Zcoin in September 2016.
Some of the notable dev members of the team are listed below.
Poramin Insom
Founder and Core Developer
Poramin Insom created what was the world's 4th most valuable cryptocurrency in February 2014. He is also the world's first person to implement stealth addresses in QT-Wallets, improving cryptocurrency anonymity. He earned a master’s degree in Information Security from Johns Hopkins University, where he wrote a paper on a proposed practical implementation of the Zerocoin protocol.
Alexander N.
Developer
Alexander N. aka Aizensou is a full-stack developer who has experience in many programming languages (C++, C#, Python, Perl, Java etc.) and has been involved in the cryptocurrency space since 2013. He has a broad development portfolio from low level APIs in Python and C++ to Android native applications in Java. In addition to his involvement in cryptocurrencies, Alexander was doing his P.h.D. in machine learning at a German university from 2012 to 2016.
Saran Siriphantnon
Developer
Saran Siriphantnon is the CTO of Satang.co/Satoshift, a fintech company focusing on creating an open financial system for Southeast Asia. He served as President of the Computer System Administrator Group at King Mongkut's Institute of Technology Ladkrabang.
Tadhg Riordan
Solidity Developer
Tadhg Riordan is a 24 year old Software Developer from Wexford, Ireland. He recently completed his MSc from Trinity College Dublin, where he worked with Blockchain privacy mechanisms, focusing particularly on Zero-Knowledge Proofs and the Ethereum platform. He is a strong advocate for the adoption of cryptocurrency and for complete financial privacy.
Apart from these, their team comprises of other developers, community managers, support personnel and advisors who maintain the required balance.

Advisors:

Aram Jivanyan (Cryptography Advisor): Co-Founder at Skycryptor & KMSchai
Torphop Korgtadam (It Security Consultant): Senior Vice President, Head Of Internal Audit Strategy, Innovation and Decision Science at United Overseas Bank Limited
Alexander N. aka Aizensou (Advisor)

Unique/Key Features Against Its Competitors:

  • Anonymous transactions. The project establishes a notably higher level of anonymity and seeks to bypass current analysis techniques which governments use to reveal the identity of users.
  • Not subject to transaction graph analysis. Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands.
  • Innovative process. Tokens are burned cryptographically and replaced with new coins without a transaction history. This actively prevents anyone else from using the tokens again and stops the public from being directed to a user's transaction history.
  • Transparency focused. Zcoin's main advantage is its auditable money supply.

What are Bitcoin transaction fees? Can I change them? HOW TO AVOID PAYING HIGH BITCOIN FEES?  LEDGER NANO S EDITION

Paying so much fee for that will cause people to make one bigger transaction instead of 175 small ones. This is bad for you i know, but i dont think you can do anithing about it, except try to make the transaction without fee and take the risk that the transaction will not confirm. Min Transaction Relay Fee Fee rates (in BTC/kB) smaller than this are considered zero fee for relaying, mining and transaction creation. Please provide a valid number (min: 0, max: ) Whitelist Relay Accept relayed transactions received from whitelisted peers even when not relaying transactions. Bitcoin transaction fees are usually quite inexpensive; the average transaction fee at time of writing is just $0.30. However, Bitcoin transaction fees, unlike the transaction fees charged by banks and other payment providers, do not have a set percentage rate (e.g. 0.3% of the transaction). Instead, Bitcoin users set their own transaction fees ... Bitcoin-Qt does prompt the user to accept the fee before the transaction is sent (they may cancel the transaction if they are not willing to pay the fee). Note that a typical transaction is 500 bytes, so the typical transaction fee for low-priority transactions is 0.1 mBTC (0.0001 BTC), regardless of the number of bitcoins sent.
