The blocklist system IFTAS proposes is called CARIAD - "Consensus Aggregated Retractable IFTAS Allowlist Denylist".
CARIAD's blocking data will be aggregated from two sources. The first is the Facebook Mafia spider-holed at Stanford, which fabricated the CSAM-scare influence operation that roiled the fedi a few months ago. More on them here: https://kolektiva.social/@ophiocephalic/110772380949893619
The second is "an aggregation of at least ten of the largest ActivityPub service providers"; this would seem to be a sugar pill to win over Mastodon gGmbH and a few other megaservers.
The system itself is somewhat similar to that proposed in the Nivenly FSEP plan which has proven so controversial over the last couple of months; except that, instead of centralizing blocklist control with WelshPixie, CARIAD centralizes control with Meta-linked authoritarian techbros.
