The proposal of BIPs such as 300 and 301, advocating for broader sidechain support, merges, and pegging mechanisms, introduces new trust surfaces involving miners, custodians, and multi-signature schemes. Participants acknowledge that trust modeling in these systems is a compromise—introducing new attack vectors or opportunities for miners to “swap out rewards” by undermining mechanisms like peg-in and peg-out protocols.
