Plasma’s cross chain re staking sounds elegant: stake XPL once validate multiple chains via light clients. But key questions remain.
How do you prove a false Ethereum attestation on Plasma without full state? Light clients verify headers not transaction absence.
Add mismatched finality (ETH vs Solana vs BTC) and validators running 5+ chain clients and you are selecting for institutions only. This either fixes fragmentation or just shifts trust assumptions.
