DigiByte (DGB)
A Decentralized UTXO PoW Blockchain with SegWit and Smart Contract Support.- DigiByte (DGB) is a decentralized UTXO blockchain that was launched in January 2014. The project is built on the code of Litecoin, but with several modifications.
- In February 2014, the project introduced DigiShield, a real-time difficulty adjustment mechanism which stablizes block time despite exponential changes in mining hash power.
- DGB has a maximum supply of 21 billion, which will be fully mined by 2035. 0.5% of the total DGB supply was pre-mined, and distributed to early community members. The network has a block time of 15 seconds, and is mined with SHA256d (available for BTC miners), Skein, Qubit, Odocrypt (FPGA), and Scrypt (available for LTC miners) consensus algorithms.
- The Odocrypt consensus algorithm was developed by the DigiByte team and automatically modifies itself every 10 days in order to prevent ASIC dominance. The algorithm was implemented in July 2019.
- DigiByte is one of the first decentralized networks to implement Segregated Witness (SegWit), a first layer solution which modifies the structure of transaction blocks and improves overall network scalability. DigiByte has also allowed the implementation of smart contracts by enabling OP_codes.
