DigiByte (DGB)DGB
A multi-algorithm UTXO chain launched in January 2014 with 15-second blocks, five mining algorithms and a 21 billion coin cap.
The wiki's angle: DigiByte answered Bitcoin's one-algorithm mining with five, and was early with SegWit in 2017 while Bitcoin itself was still stuck in the activation fight.[1][2]

Launch
The DigiByte Core README says DigiByte was “founded in early 2014” and lists its genesis block text as “USA Today: 10/Jan/2014, Target: Data stolen from up to 110M customers”[1]. The README describes the chain as public, UTXO based and multi-algorithm, and compares it with Bitcoin point by point; this wiki has not yet sourced which codebase the project started from[1].
Design
Per the README, DigiByte mines on five algorithms — SHA256, Scrypt, Odocrypt, Skein and Qubit — each taking about 20% of blocks, with 15-second blocks and a cap of 21 billion DigiBytes reached in 2035[1]. It lists five hard forks: DigiShield at block 67,200 on 28 February 2014, MultiAlgo, MultiShield, DigiSpeed and, in July 2019, Odocrypt[1].
SegWit
The README claims DigiByte was the “First major altcoin to successfully activate Segwit” in April 2017, months before SegWit activated on Bitcoin[1].
