Some projects have built synthetic price pegs, which is not a true bridge. Other projects are supply pegs, but have centralized parties adding friction to the minting and redemption process and therefore, are not censorship-resistant systems. Some new bridges are decentralized supply pegs, however, those security models are less safe. They rely on a ⅔ honesty assumption, use brand new “roll your own crypto” rather than peer-reviewed, widely deployed t-ECDSA cryptography), or use an outdated capital-inefficient approach that tBTC has already outgrown in v2 of the protocol.
