App ecosystem adoptionThe network launched with 50 applications, but sustaining growth requires attracting developers away from Ethereum, Solana and other established chains.
Validator decentralizationReal-time execution requires tight coordination among validators; ensuring decentralization while maintaining instant finality is an engineering challenge.
Sequencer centralizationCurrently the MegaETH sequencer is centralized. Decentralizing the sequencer while maintaining real-time finality is an open problem.
Physics limits
Real-time determinism and decentralizationProviding instant transaction finality across a decentralized network of validators requires solving distributed consensus problems that normally take rounds of communication.
Ethereum settlement bandwidthEthereum mainnet can process a limited number of transactions per second. As MegaETH grows, the cost of posting proofs to Ethereum becomes a bottleneck.
State growthLike all blockchains, MegaETH's state (account balances, smart contract code) grows over time, requiring full nodes to store ever-increasing amounts of data.
How it works
3 parts
Real-time execution
Transactions finalize immediately
Unlike typical rollups that batch transactions and wait for Ethereum confirmation, MegaETH uses deterministic ordering to finalize transactions instantly.
Ethereum settlement
Cryptographic proofs posted to Ethereum
Transaction batches are compressed and posted to Ethereum mainnet, where proofs verify the rollup's correctness.
Two-token economics
MEGA governance and USDm stablecoin
MEGA tokens control protocol upgrades and rewards. USDm is the native stablecoin used for gas fees and settlement.
