UnitedBitcoin is a fork of Bitcoin, designed to improve on the imperfections of Bitcoin. The most important function of UB is to be a secure medium of exchange. It represents a joint credit system that aims to transfer inactive account balances to the UnitedBitcoin Foundation. These inactive balances include money locked in addresses that are no longer accessed by its owners.UnitedBitcoin’s goal is to find a purpose for inactive wallets and create a stablecoin via the association of smart contracts and joint credit. Thanks to UnitedBitcoin users can easily execute financial contracts. Users can add restrictions and improve functionality, without upgrading or modifying the blockchain.The halving time, block speed and total volume are the same as those of Bitcoin. UnitedBitcoin uses the mining algorithm of Bitcoin. It features the same proof of work mechanism but the initial difficulty is reduced. The currency unit of UnitedBitcoin is UBTC. The block reward is 1 UBTC. Block time is lowered to 1 minute. UB implements replay protection by developing new transaction signatures. So it is impossible the transactions on one chain to be replayed on another one.
