ScrollIntermediateThey rank how closely a zkEVM matches Ethereum: type 1 changes nothing, type 2 swaps data structures, 2.5 reprices gas, 3 drops features like precompiles, and type 4 only compiles the same Solidity to another VM.

SeiIntermediateSei executes a block's transactions in parallel, tracks what each one read and wrote, and re-executes any that conflict, so results match serial order. Contracts need no changes, but shared hot storage slots still serialize.
#consensus#performance#scaling
FlowIntermediateCollection nodes batch, consensus orders, a few heavy execution nodes run transactions and many light verifiers check chunks. Cadence resources are typed assets that can't be copied or lost, guarded by entitlements.

LineaIntermediateDeposits are anchored on Linea within minutes. Withdrawals wait until a proof covering them is finalized on Ethereum, then need a separate L1 claim. Fast bridges skip the wait by adding trust.

Bitcoin CashBeginnerBCH forked in August 2017 to scale with bigger blocks instead of SegWit. Today it has a 32 MB adaptive limit, native CashTokens, CashAddr addresses, no SegWit or RBF, low fees and far less hashrate than BTC.

MonadAdvancedMonad runs transactions optimistically in parallel and re-executes conflicts while committing in order, executes after consensus instead of during it, and uses MonadDb for parallel state reads. Gas is charged on the limit.

KaspaIntermediateEach Kaspa block references every tip it sees, so parallel blocks are merged, not orphaned. GHOSTDAG colours well-connected blocks blue and orders the DAG, supporting 10 PoW blocks per second since Crescendo.

CelestiaIntermediateA DA layer guarantees rollup data was published. Celestia erasure-codes blocks into a 2D square, so light nodes sampling a few random shares catch withholding; fraud proofs catch bad encoding.

ZKsyncAdvancedzksolc compiles to EraVM, not the EVM: CREATE/CREATE2 addresses differ, factories need known bytecode, every account is a smart account, pubdata changes gas, and the 2300-gas .transfer stipend can fail.

ArbitrumIntermediateRollups execute off-chain and post data to Ethereum. Optimistic rollups like Arbitrum assume validity unless a fault proof wins during a challenge window; ZK rollups post a validity proof per batch.
