There seems to be a misunderstanding, or perhaps an acceptance for the sake of simplicity, of what consensus mechanisms blockchains use.

Blockchains, and cryptocurrencies by extension, have captured the imagination of almost everyone. Hardly a day goes by without Bitcoin being mentioned in the news.

If you spend enough time in the cryptocurrency/digital assets space, you will hear the words “Zero Knowledge” mentioned quiet often. For most, the maths just block out all the maths and cryptography terminology when people talk about zero knowledge proofs.

If you have been in crypto for a while, you will no doubt have heard the term “Not Your Keys, Not Your Coins”. It’s essentially a view, adopted mostly by “Bitcoiners”, that encourages users to hold their own private keys (for Bitcoin) instead of entrusting the keys to a third-party i.e. a Crypto Exchange.

In December 2020, ETH2.0 Beacon Chain launched. This Phase 0 launched forms part of a multi-year process that will see ETH1.x transform from a PoW (Proof of Work) to a PoS (Proof of Stake) blockchain.
