Boolberry is a privacy cryptocurrency officially released on September 8, 2016 using a Proof-of-Work (PoW) Wild Keccak consensus mechanism based on CryptoNote. The Boolberry blockchain reduced its blockchain size by 60-90%% by pruning ring signatures and improved its users anonymity by creating unlinkable outputs. The Boolberry project primarily relies on donation-based crowd funding and allows miners of Boolberry coins to vote how many Boolberry coins are allocated for project development (up to a maximum of 1% of mined coins).
