GoldBlocks (GB) is a decentralised, open-source cryptocurrency forked from BlackCoin in May 2016. It's a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin which can be either "mined" by a computer or "minted" through a process called "staking". The PoW part of the coin uses the X11 hashing algorithm (11 rounds of scientific hashing functions that include blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd and echo) with a 60-second block time and a total coin supply of 24.7 million. The coin's PoS method offers a 10% annual interest on staked coins, with the total supply capped at 50 million coins. Original announcement.
