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.
#consensus#nodes#scaling
InjectiveIntermediateInjective's exchange module matches orders once per block. New orders on the same side clear at one uniform price, so a transaction's position in the block doesn't matter and sandwiches have nothing to capture.

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.

SolanaIntermediateThe priority fee is CU limit × CU price in micro-lamports, on top of 5,000 lamports per signature. Simulate to size the limit, price from recent fees on the accounts you write, and never request 1.4M by default.

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.

BitcoinIntermediateOrdinals number every sat and track it first-in-first-out; inscriptions put files in Taproot witness data on a sat; Runes are UTXO-based tokens in OP_RETURN. Indexers, not nodes, interpret all of them.

HyperliquidIntermediateHyperliquid builds the exchange into the chain: HyperCore runs order books, margin, liquidations and the HLP vault as native logic under HotStuff-style HyperBFT, with HyperEVM alongside under the same consensus.

StacksIntermediateStacks miners spend BTC that goes to STX stackers, Clarity contracts can read Bitcoin state, and Nakamoto added fast blocks with Bitcoin finality. sBTC is a 1:1 BTC-backed token secured by a threshold signer set.
