Technical Notes: RGB vs Ethereum Rollup — Two modes of "off-chain execution + on-chain commitment" that reflect completely different philosophies. 🌈 RGB: Local ledger, peer-to-peer transmission, distributed state machine • Each transaction generates a consignment file (state fragment + ancestor chain). • Sent to the recipient, verified locally (tweak / merkle + state machine rules). • No global ledger → double-spending detection relies on collecting scattered consignments. • Philosophy: Distributed state machine, as long as both parties verify, global consistency is not the goal. 🟣 Rollup: Global ledger, batch proofs, global state machine • Rollup nodes execute thousands of transactions off-chain. • Regularly submit global state root to the main chain. • zk Rollup → mathematical proof of global correctness; Optimistic → fraud proof + challenge mechanism. • Philosophy: Global state machine operates on L2, main chain is responsible for security & finality. #Bitcoin #RGB #Ordinals @BitlightLabs @BitMask_App @dr_orlovsky @VitalikButerin
