2X2 Coin – 2X2 Coin

2×2 is a decentralized cryptocurrency project designed for long-term sustainability, network security, and predictable coin issuance. The project uses a hybrid Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus mechanism with a fixed premine and a controlled annual coin emission schedule. We have created 2×2 – PoW/PoS cryptocurrency which, despite the crypto market fluctuations, can generate passive income stream for its holders.

Technology
Hashing algorithm: Scrypt
Proof type: Proof-of-Stake and Proof-of-Work
Block time:60 seconds
2x2 aims to provide:
Fair initial distribution with premine
Sustainable and predictable inflation
Long-term security incentives for miners and validators
Clear roadmap for coin supply and tail emission

Coin Supply & Inflation
Premine: 11,000,000 coins
Annual coin emission: Varies by year, based on reward schedule
Blocks per year: 262,800
Tail emission (year 20+): 1,000 coins per block

Coin Supply & Inflation Schedule

The coin supply schedule ensures high initial growth to bootstrap the network, followed by controlled long-term inflation and a stable tail emission.
Consensus Mechanism Proof-of-Work (PoW)
Rewards decrease over time according to a deterministic block schedule
Initial premine at genesis block: 11,000,000 coins
Designed to incentivize early miners while maintaining predictable supply
Proof-of-Stake (PoS)
Rewards are equal to PoW rewards per block after early phase
Project Highlights
Sustainable & predictable inflation for 20+ years
Hybrid PoW/PoS consensus for security and decentralization
Clear long-term coin supply plan with tail emission
Deterministic block rewards to maintain network incentives
Provides continuous incentives for validators securing the network
Tail emission ensures validators remain incentivized indefinitely

Proof-of-Stake
There is no minimum amount of coins required for staking 2X2. However the more users stake, the more difficulty and the more the network weight, which leads to wallets with small balance having low staking weight and enlarged staking period. Staking weight grows every confirmation increasing, over time, the chance of getting a stake reward. You must leave your wallet online to receive the reward. And unlocked for Staking.

Proof-of-Work
It is a decentralized blockchain consensus mechanism that secures networks like 2x2Coin by requiring participants (miners) to solve complex mathematical problems to validate transactions and create new blocks.
Miners use specialized hardware to solve these complex mathematical problems (hashes). The first to solve it is to add the block to the blockchain, a process known as PoW mining.
We have a code developed for mining through the wallet on the Windows System.
Soon we will have our own mining pool.

Security settings

Encrypting wallet
Go to menu Settings – Encrypt wallet. In the dialoge that appears, set a safe password, then confirm new passphrase by repeating it, click on OK. Must be careful not to forget the passphrase. If you forget there is no way to recover lost passphrase and access coins.
Changing passphrase
Go to menu Settings – Change passphrase. In the dialoge that appears, enter current passphrase, set new passphrase, then confirm new passphrase by repeating it.
Backup wallet
Go to menu File – Backup wallet. In the dialoge that appears, enter file name, choose the folder location and save the file to your computer.
We highly recommend for reliable data storage to make at least two copies of your wallet.dat file on different discs – for example, one on your hard disc, the another – on USB.
Important: when you encrypt your wallet or change passphrase, previous backups you have made of your wallet file should be replaces with newly generated, encrypted wallet file. For security reasons, previous backups of unencrypted wallet (or wallet with old passphrase) will become useless as soon as you start using the new, encrypted wallet (or wallet with new passphrase).
Lock/Unlock wallet
Each time your open the wallet it is locked by default. Locked wallet is unabled to stake. To enable staking you must unlock your wallet.
Go to menu Settings – Unlock wallet. In the dialoge that appears, enter your passphrase and put a checkmark in the For staking only. If you remove the mark from the checkbox, the wallet becomes unencrypted and anyone with access to your computer / wallet will have access to your funds. We highly recommend removing the mark only for multiply payments to send and always encrypt the wallet before leaving your computer (esüecially if you have.

Frequently Asked Questions

Where is 2×2 wallet file located on my computer?
Your 2×2 wallet file (wallet.dat) can be found in the folder C:\Users\User\AppData\Roaming\2x2Coin or in the folder selected when the wallet was first opened.
If AppData folder is not visible, folder settings for “hide operating system files” need to be unchecked, and “show hidden files and folders” need to be checked.
How do I know if my coins are staking or not?
Point at the staking icon (Up Arrow) at the bottom right for some statistics.
If the icon is grey you are not staking for one of two reasons – you wallet is locked (at this point unlock the wallet for staking only) or you don’t have matire coins.
If icon is green, you are staking. Move the pointer over the icon to see your staking weight, network weight and expected time to earn reward.
Why does expected time to earn reward decrease and then increase again?
This is because the difficulty fluctuates according to number of users on network and network weight. Just be patient, you’ll stake soon.
Do I need to run my wallet 24/7?
Each 2×2 wallet is a node in the 2×2 network. If a wallet is offline it’s not synced with the network and can’t participate in sighning blocks. Thus your coins can stake only if your wallet is online and synced with the network. However, there is another conditions for staking – coins must be mature. Therefore, if you have mature coins you need to keep your wallet open (and unlocked for staking), if no mature coins yet – no need to keep the wallet open.
What are “orphans”? Why are some of my minted coins “generated but not accepted”?
Time by time you could mint a block that fails to get into the blockchain, this blocks are called “orphans”. This is because someone else is staking and finding a block at the same time as you but a little bit faster. Fast-speed stable internet is crucial for staking! If you get a lot of orphaned blocks, take a look at your internet connection.
Will there be any updates to the wallet?
We are working on creating a new wallet.
Compatible with the latest operating systems. We will announce updates for community support at https://discord.gg/RZnFRXq. Thank you for your understanding.

2X2 Staking Tutorial

1. Download 2×2 wallet.
2. Install and open the wallet and let it sync. Synchronization goes automatically.
3. Go to “Settings” and “Encrypt wallet”. Create a secure password. Try to remember your password without writing it down, but beware, the password can’t be recovered: the lost password – the lost coins.
4. Restart the wallet.
5. Go to “Receive coins” and create an address.
6. Withdraw purchased 2×2 coins from an exchange to this newly created address. Once you receive the coins to the wallet, staking period starts.
7. Go to “Settings”, select “Unlock wallet for staking only” and enter your password.
That’s all, congratulations!
2×2 coins stake at least 4 hours, since that’s how long it grows to maturity. You can check coins maturity in the bottom right of the wallet. Keep your wallet open and unlocked to stake the most efficiently.
