The old system also provided a way for domains to be seized, which would be the equivalent of an identity being revoked. This can't happen with blockchain based identities, so it provides more certainty. Blockchain based domains are tie human rememberable names to identities well. Which while GPG is associated with email addresses, the association seems more difficult to fake, and provides non-technical people certainty of identity in a similar way to how they would normally trust a website.
Yes it's pretty much the same as Facebook Like, except that the accounts are decentralized so could never be banned. Also you could have a group of people "like" an edit as a group (shared identity).
This project feels a lot like “we could do things with blockchain because…we can do things with blockchain”
As mentioned elsewhere, there’s already PKI stuff for Wikipedia, there doesn’t seem to be a lot of point, or benefit? Just because there’s some sort-of-convenient infra in ETH land doesn’t automatically make that inherently useful to anywhere else, and honestly comes across more like a veiled attempt to pump MAU’s on blockchains/meta mask.
Still can’t shake the idea that this is a solution waiting for a problem, and this isn’t really it.
OP: two points.
1. It helps harness the help from EVM wallet's adoption. Most people don't know how to use GPG. Most GPG tools aren't built with mind of regular user as target audience.
2. We could soon see on-chain identities, and organizational relationships linked to it. E.g. one could use ERC-1271 to have a contract attest to a signature.
Crypto made public private keys more ubiquitous, not completely, but much much more.
Speculation drives innovation.
OP: Society with and without "phones" are foundamentally different. The introduction and adoption of cryptography into daily life is at this level.
In the beginning, we probably could only attract a small group of adoptors. But the monthly active editors of Wikipedia is only O(100000) and the number of editors that actively review and "like" edits are even smaller, around O(1000). This is the scale of users that have made great impact on Wikipedia and the world's knowledge.
