Abstract
Proof of Stake’s security has proven itself over years of testing. Advances in this technology in Blackcoin’s Proof-of-Stake 3.0 have solved the issues faced with Coin-Age, Block Reward and Blockchain Precomputation. The protocol is robust and keeps nodes connected to the network. It disincentives inactive nodes. In this paper we will highlight and outline the advantages and perform a security analysis of the system. We also outline ideas here in Blackcoin to potentially increase security further.
