A topic I once tweeted about but didn't really pursue, that's now looking more interesting/relevant, is what I call a lightweight "nocoin" notary chain/web. Some thoughts on what that would be, and why it's interesting. A ๐งต
This idea started from looking at the definition of "blockchain" (merkle tree + consensus protocol) and asking whether such a thing necessarily facilitates running stupid toy money ponzi schemes on top of it.
@dalias I don't see how we ever solve the problem of binding human memorable name to random keys without signed merkle + consensus, unless we depend on central point of trust like DNS (which can be ok sometimes)
