The existence of strong BSD community here on Mastodon (and reading AST’s book about operating systems) has reminded me about good old days of using #FreeBSD. One of the effects is writing and submitting a port of #BlackCoin daemon/CLI: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226501

#cryptocurrency #cryptocurrencies

I’ve been writing a new #proof_of_stake #cryptocurrency in #Erlang, using #Tendermint as a consensus engine. Features accounts instead of UTXOs, simple design, transaction messages and flexible economic structure. Burning #BlackCoin is proposed to obtain initial coin distribution.

According to Digicoinomist, #Bitcoin consumes currently 14.43 TWh of #energy annually (with mining cost of $721,420,025) compared to #VISA’s 0.54 TWh, making VISA 26,505 times more energy efficient per transaction.

This is not an inherent #cryptocurrency problem, as there are #proof_of_stake #cryptocurrencies like #BlackCoin which secure #blockchain with the scarce resource being money owned instead of energy expended. Knowledge about them still doesn’t seem to be widespread.
