Overview of 'staking' in a variety of projects

This post considers “staking”, the practice of using cryptographic coins or tokens to participate in some functional or governance role(s) within a decentralized (blockchain) production effort. The classic example is Proof of Stake (PoS) consensus, where token holders collectively perform the task of maintaining consensus and creating new blocks. This function is performed by Proof of Work miners in Bitcoin. The term “staking” is now used much more broadly, including Delegated Proof of Stake systems and also hybrid forms.
