Proof of Burn (PoB): The mining mechanism used in Stacks 1.0, Blockstack’s first implementation of the blockchain and platform core
Proof of Transfer (PoX) : The Stacks 2.0 mining mechanism. As part of Stacking consensus enables benefits not possible with just proof-of-work or proof-of-stake.
Stacks : the name used for both (1) the Blockstack blockchain and (2) the name of the Blockstack native token, which is also known by it’s ticker symbol STX.
Stacks 2.0 : the second major version of the Blockstack blockchain and platform core. Implemented in the Rust programming language. It includes native Stacks mining, the Clarity smart contract language, and other improvements.
Stacking : The consensus algorithm used for Stacks 2.0.
Stacking takes the same Bitcoin used in Stacks 1.0 (PoB), but instead of destroying it, transfers it to users who are (1) holding Stacks tokens and (2) actively participating in the consensus algorithm. Once every reward cycle (roughly once per month), every user who meets the eligibility for Stacking would receive a reward (a payout) of Bitcoin from the network.
