My views on blockchain / bitcoin
Going from abstract to concrete:
- Private currency: good. I would love to have lots of them, just as I love both gold and silver.
- Blockchain: not so good, more of a solution in search of a problem. The only advantage it has compared to an append-only database is decentralization… and I don't see a need for that. I would much rather have many private currencies. Also, in practice most coins are actually centralized, or at least a very small oligarchy.
- Bitcoin: nah. Really bad. Incredibly slow to initialize, slow transactions, easy to control by a sustained state-level effort, very low cap on number of transactions per second, plenty of bugs, hard-forks which means the code is actually controlled by a small group (which in turn means that I can't trust that the currency itself is decentralized)… nah.
In conclusion, I like the initiative, and I'm 100% behind the idea that we need to separate states and money, but we're nowhere near yet.
