“You don’t want to use the blockchain unless there’s actually some kind of dispute; all cooperative transactions in the world can exist off of the blockchain and there’s no reason to actually use a blockchain for them”
— Nadav Kohen

Bitcoin's proof-of-work blockchain solves a specific problem: achieving consensus of a distributed ledger without a central authority. Out of this decentralised network, new properties emerge like censorship resistance and probabilistic finality.

Bitcoin's success led to an explosion of altcoins, with most claiming to improve upon Bitcoin somehow, whether it's speed, privacy or scalability. However, blockchains are a delicate balance of specific tradeoffs, and these altcoins pale in comparison to Bitcoin's decentralisation and censorship resistance.

While changing a parameter might seem to add functionality, it can also introduce unintended consequences. To resist influence and attacks, Bitcoin must remain decentralised by allowing for easy validation.

Can we achieve sufficient privacy and functionality on the second layer? And why are other consensus methods, like proof-of-stake, flawed?

In this interview, I talk to Suredbits software engineer Nadav Kohen. We discuss why blockchains must scale with second layers, proof-of-stake vs proof of work, and tradeoffs of privacy technology.
