"...Bitcoin is a living, breathing, developing code base that is moving forward with new features to continue to scale..." There is exactly zero progress to make it scale in the last 10+ years.

What happened to the lightning network? (Serious question, I am out of the loop.)

I wonder how strong would Elliptic Curve Cryptography be compared to other methods if there is a major breakthrough in quantum computing.

I wish this were talked about more. Quantum computing is the biggest long-term threat to crypto imo. What's the plan once elliptic curve cryptography can be broken? There will be a point in time where there are just a few quantum computers that can break everything before the general public has access to quantum computing. Can crypto work in that scenario? Normal computers wouldn't be able to work with the beastly al…

> I wish this were talked about more.

This is talked about all the time in Bitcoin dev circles.

That's a lot of upvotes. Do you folks really spend hours going through the whole blog post? I for one can never go through the whole blog post. My brain would be shouting at me the whole time to work on something that can generate passive recurring revenue instead.

You could also read it for fun, curiosity, and/or because you already have enough recurring revenue.

Taproot doesn't make bitcoin scale its mainly to increase privacy.

Taproot decreases the size of multisig and other complex transactions significantly, in the happy path of a cooperative signature.

It also enables Schnorr, which produces smaller signatures than ECDSA.

It also contains features to further improve the efficiency of Lightning, which is a shockingly effective scaling mechanism.

Maybe most of his job is hype & marketing without delivering much

FSD rollout has been delayed many times. He's underperforming.

This is a very cynical way of looking at development progress. Did the iPhone team underperform by shipping in 2007 instead of 2005?

It launched, is usable in most wallets, and is starting to get adoption. It's going to be a key piece of the recently passed legislation in El Salvador which makes Bitcoin legal tender.
