PHPCoin (PHP)
Pure PHP blockchain built for Web

We are proudly introduce new unique blockchain technology and coin.

About PHPCoin
Why another coin?

While many coins are just designed to build, gain interest, give fast profit to owners and exit as potential scam, PHPCoin will tend to develop through a large developer community who can contribute to the project.

Also PHPCoin is designed as some kind of "green" coin which is tend to solve issue of heavy mining algorithms by utilising its own and unique elapsed proof of work (EPOW)

PHPCoin is built on the web based platform which is easily understandable to a wider number of developers. It explains basic blockchain principles and allows people to understand its full purpose not just for earning profit.

In that way PHPCoin will implement decentralized apps and databases and smart contracts written fully in well known and popular language php.

What differentiate PHPCoin from other cryptocurrencies?

Open and easy
Built on the web based platform which is easily understandable to a wider number of developers. It explains basic blockchain principles and allows people to understand its full purpose.

Lightweight coin
Designed as "green" coin which is tend to solve issue of heavy mining algorithms by utilising its own and unique elapsed proof of work (EPOW), minable with any web browser.

Built for web
Creates a network of nodes which while keeping the network secure, hosts decentralized apps, and earn rewards for its services

Blockchain consensys
Phpcoin blockchain tries to solve actual issues with traditional proof of work consensus (POW). As POW is often criticized  as a very energy waste, PHP Coin utilizes its own lightweight version of POW, called EPOW -  Elapsed Proof Of Work.
Basic principle of this algorithm is that valid hash is calculated minimum one per second for each miner in such a way that more time elapsed from target block time it will be easier to mine block.

Mining process
Miners generate a new block on the network.
In order to do that, miners get work from a connected node. That work contains the latest block info and pending transactions from mempool.
Then the miner goes into a loop and calculates his elapsed times from the last block.
To prove his work, the miner hashes the base string with argon and its address.
Based on its address it calculates hit value which is changed every second elapsed from last block time.
With a given difficulty for the next block which is calculated from node, miner calculates the target and when its hit value becomes higher than target it mines a block.

Explanation of mining hash calculation
https://docs.google.com/drawings/d/171dKeVOGB8NFwOtJyN_NqYpyxOWcVwOtad7r5DYatHg/edit

Target is not fixed, it is calculated from difficulty and is lower as time passes from the previous block. It is centered to be optimal to mine blocks for given block time.

After finding the hash, the miner sends it to the associated node. Node checks miner hash, and if it is validated, node adds a new block to blockchain. For that block beside mempool transactions node adds two reward transactions.
First one is reward (90%) to miner who submitted targeted hash and second is reward to node (10%) who added block to blockchain. Amount for rewards are calculated from actual block reward.
If node is also a miner then the whole reward goes to it.

Difficulty adjustment
Based on a simple formula that calculates the last 10 blocks, difficulty is calculated and adjusted for every block. If a block is found faster than block target time, difficulty is increased by 5%, otherwise it is decreased by 5%.

Start mining in browser

1. Go to wallet node: https://wallet.phpcoin.net/apps/wallet/login.php
2. Click on link to create new address, or directly to link: https://wallet.phpcoin.net/apps/wallet/login.php?action=signup
3. Create your account (write down generated keys)
4. Go to faucet node: https://faucet.phpcoin.net/apps/faucet/
5. Enter your address, and click on button Receive
6. Wait for transaction to be added to blockchain
7. Go to wallet, login with public/private key
8. Send on transaction to some address (for example back to faucet: PYcFC7BvhJ4queNMwbDuxBGdqSmBvyjXZT)
9. Wait for transaction to be added to blockchain
10. Go to miner node: https://miner1.phpcoin.net/apps/miner/
11. Enter you address and click Start to mine

What means Dropped in mining?

It means that miner detected new block on network and need to start over

Can I mine from wallet and browser at the same time? Why miner does not use CPU heavily?

You can mine but on different addresses.
Mining on same address does not improve chances, because in every moment of time hash is same for same address.
It is planned to be easy mining, not impacting CPU or memory, so any device can mine coin.
Details about Elapsed Proof of Work, you can check in whitepaper document.

get started

Unusual project

ookkkk ready mine :o :o :o

0 Accepted 0 Rejected 143 Dropped  BALANCE 0 ??? ??? ???

Any antibot protection? I think there is already bots mining this.

It looks very strange, how does it work, what resources does it involve?

Just no luck :-(

It is basic mathematics calculation and very simple. Please check whitepaper for explanation.
That is idea, to not be heavy on any resources, so any device can mine it.

why when i mining with wallet its mining 15 min  and i have some error and mining stoping

That problem is just resolved, please download new wallet version.

New version of wallet (1.06) not mining correctly.
"Error in miner
Error: TypeError: Cannot read property 'height' of undefined a minute ago"

not working
"Hash rejected
generator-disabled"

After a year of development this coin will soon go public.
Soon we will publish more information.

Mainnet will be launched on April 1st 12 PM UTC.

https://i.ibb.co/GF2vZvC/phpcoin-launch.jpg (https://ibb.co/wYWNnNp)

Small explanation of what's going on with this coin.

This coin was originally launched about 1.5 years ago but then it had many issues ,not mature enough and not ready for public adoption.
We spent that time developing and improving coin software and building a testing community.

In that period we developed masternoding, staking, decentralized apps and started working on smart contracts.

That phase and chain we are calling mainnet-alpha and it is still running.
Coins earned and will be earned in this chain can be swapped directly or via token to mainnet after its launch.

On April 1st we are launching a new chain where the total current mainnet-alpha chain supply is in genesis and can be swapped back from earned coins and tokens.

So there are few ways how users can participate in new chain:
1. Earn coins on mainnet-alpha by mining, masternoding, staking and swap that coins later to mainnet coin or token
2. Buy token and swap it to mainnet coin
3. Mine coin on mainnet

After we collect enough funds from selling the token we will use it to list on some exchange.

Also note that the first 2 weeks (approx) from launch coin can be only mined, after that it will start the masternoding phase with dynamic collateral.

Any updates on the project? Joined discord but it seems dead, rarely any chat.

Project is steady and running.

If there is less activity on chat, it seems that everything is working  ;)

You can try PHPCoin and earn some by visiting new interactive demo:
