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…

There's a lot of research and practical work on quantum-proof cryptography which is already in use in some cryptocurrencies - 'just' need to hardfork and update it when it's ready for Bitcoin

Daily reminder that cryptocurrencies are not == bitcoin All the problems with bitcoin are long long solved just not with bitcoin because its not possible to fix something when the majority (of hashpower) thinks its not broken or rather profit form its brokenness. FBA coins exists since 2013 or so.

> Daily reminder that cryptocurrencies are not == bitcoin This is an interesting feature of cryptocurrencies. Someone levels a fair criticism of a particular implementation but it can be handwaved away because an entirely separate cryptocurrency solved this particular problem (nevermind that whatever replacement you’ve chosen has its own host of separate problems because those can be handwaved away the same way).

The looking up of liquidity is the whole reason LN can not scale or be cheap ever. Today people in crypto may be willing to look up bitcoins they hold long term anyway. But in the real world this would be dead and trapped capital it doesn't work for you and you cant even use it to quickly buy something an take advantage of a market situation. The only reason why someone would look up capital like that if is it makes…

If I decide I want to be long BTC, why not also lock it up to earn fees?

This is reminds me of Ken Shirriff's 2014 "Bitcoins the Hard Way" blog post that also used Python to build a Bitcoin transaction from scratch: http://www.righto.com/2014/02/bitcoins-hard-way-using-raw-bi... (The subtitle of the blog is "Computer history, restoring vintage computers, IC reverse engineering, and whatever" and it is full of fascinating articles, several of which have been featured here on HN)

Thanks for the nice mention of my blog. I was wondering if anyone remembered my old bitcoin article :-)
