The distributed computing network Blockstack announced that it will launch version 2.0 of the consensus algorithm Stacks, which is scheduled to be released in the second quarter of this year. The Stacks 2.0 update includes implementations in Rust, native Stacks mining and smart contract language Clarity, and other important improvements. Officially, the new Stack2.0 consensus algorithm is called Stacking, and Proof of Transfer (PoX) will be used instead of Proof of Burn (PoB) for mining. Different from the PoB consensus that burns the base currency (Bitcoin), PoX miners will send the base currency to the Stack token holders participating in the network consensus. Currently, Blockstack ’s proposal is that the miners will send Bitcoin to the participating network consensus Stack holders. At each reward cycle (currently about monthly), the network sends Bitcoins to eligible holders.
