Changing the world, one version at a time!

BlackCoin’s Proof-of-Stake Protocol v2

The current Proof of Stake protocol has several potential security issues: coin age can be abused by malicious nodes to gain significant network weight to perform a successful double spend. Additionally, due to coin age, honest nodes can abuse the system by staking only on a periodical basis. This does not secure the network. Lastly: in the current system all components of a stake of proof are predictable enough to allow pre-computation of future proof-of-stakes. In this paper a system is proposed to solve said issues.
