Bridge validator threshold (k-of-M)

Evidence summary #

Not a k-of-M threshold model. UMA OO uses economic bonding + time window: proposer posts bond (~WETH, ~2h challenge window); if undisputed, executes; if disputed, DVM votes. Effective "threshold" is economic, not signature-based. Bond is configurable by HubPool admin (3-of-5 multisig). No cryptographic k-of-N signing — this is the key architectural distinction from Wormhole/Axelar style bridges.
