Blackoin's Proof of Stake

"In this overview of State-less/Epoch-less Proof-of-Stake cryptocurrency implementations, my objective ideally is to divide PoS implementations in two big subgroups, this being the first one. In fact, while all Proof-of-Stake implementations try and achieve the shift of work to on-chain economic value, a radical difference comes to how their own block primitive is structured; a group of PoS implementations always requires a certain amount of "Proof-of-Stake-only bytes" in the block primitive header, which is not work related. Tracing a line here helps us identify such a broad set of different implementations."

"Version n The greater your economic commitment, the greater your chance at producing a valid block. A fork of "nil-n" PoS, Proof-of-Stake version-n was first implemented in Blackcoin, as described in the Blackcoin protocol whitepaper. "

Interview with the Creator of Blackcoin

Follow The Coin

April 4, 2014

Blackcoin is a scrypt based coin launched on February 24th, 2014 with no pre mine (neither the creator, or anyone else in the crypto community, had mined it before launch). Immediately after launch the coin garnered an impressive 20 – 28GH/s in mining power from the community, a tremendous amount of resources for a coin just being introduced to the market.

Not everyone in the crypto community agrees that BlackCoin’s way of disabling PoW is stable and secure. This should be proven by long-term practice.

BlackCoin is primarily a ‘store of value’ for much of it’s holders.
