UnitedBitcoin’s philosophy is to upgrade the Bitcoin network. It has such features as Proof-of-Work inherited from Bitcoin with brand new high-speed smart contracts, fast transactions through the Lightning network, asset allocation of active addresses, no-premining, stable system with fiat currency pegged reserves, block-size increased to 8 MB and support for SegWit.
According to the roadmap of United Bitcoin, the issuance of a digital currecny pegged to fiat currencies is scheduled for April 2018. The United Bitcoin will issue its first digital currency pegged to fiat currencies using UBTC as collateral. Moreover, in April United Bitcoin promises to add support for smart contracts, as UBTC will be officially upgraded to a version with smart contracts support.
What is more, United Bitcoin will transfer all pegged currencies to smart contracts also within April 2018. Because it is too complex for color coins to support smart contracts, in order to support the smart contracts for pegged currencies, all pegged currencies will be transferred to the smart contracts system.
Later, in July 2018, United Bitcoin plans to upgrade with the Lightning Network support.
