A rollup whose transaction sequencing is driven by the Layer 1 base chain's proposers rather than a dedicated centralized sequencer. L1 proposers permissionlessly include rollup blocks as part of L1 blocks, inheriting Ethereum's censorship resistance, liveness, and decentralization. The trade-off is higher latency (constrained by L1 block times), addressed through preconfirmation mechanisms.

Based Rollup (based-rollup) Categoria: Blockchain Geral Definição: A rollup whose transaction sequencing is driven by the Layer 1 base chain's proposers rather than a dedicated centralized sequencer. L1 proposers permissionlessly include rollup blocks as part of L1 blocks, inheriting Ethereum's censorship resistance, liveness, and decentralization. The trade-off is higher latency (constrained by L1 block times), addressed through preconfirmation mechanisms. Aliases: L1-Sequenced Rollup Relacionados: Rollup, Sequencer, Preconfirmation

A Layer 2 scaling technique that executes transactions off-chain, bundles them, and posts compressed data back to L1. Optimistic rollups assume transactions are valid and use fraud proofs for disputes (7-day challenge period). ZK rollups generate cryptographic validity proofs for every batch. Rollups inherit L1 security while providing 10-100x throughput improvement.
The entity responsible for ordering, batching, and submitting transactions in a Layer 2 rollup. Most rollups currently use a single centralized sequencer operated by the rollup team. Decentralized and shared sequencer designs (Espresso, Astria) distribute this power across a network of operators, enabling cross-rollup atomic composability and reducing single points of failure.
A credible, collateral-backed promise from a block proposer or sequencer that a transaction will be included in a future block, providing near-instant soft confirmation before on-chain finality. Preconfirmations address latency in based rollups where Ethereum's 12-second block time is too slow for UX. Implementations achieve sub-10ms guarantees, secured by restaked ETH with slashing for broken commitments.

A distributed, append-only ledger that records transactions in cryptographically linked blocks. Each block contains a hash of the previous block, forming an immutable chain. Nodes in the network maintain copies of the ledger and reach agreement through consensus mechanisms. Blockchains enable trustless, decentralized record-keeping without a central authority.
The protocol by which nodes in a distributed network agree on the current state of the ledger. Common mechanisms include Proof of Work (Bitcoin), Proof of Stake (Ethereum, Solana), and BFT variants. Consensus ensures all honest nodes converge on the same transaction history despite potential network delays or malicious actors.
A consensus mechanism where validators are selected to produce blocks based on the amount of cryptocurrency they have staked (locked) as collateral. PoS is energy-efficient compared to Proof of Work. Misbehaving validators risk losing their stake (slashing). Solana, Ethereum (post-Merge), Cosmos, and Cardano use PoS variants.
A consensus mechanism where miners compete to solve computationally expensive puzzles to produce blocks and earn rewards. PoW provides strong security (51% attack resistance) but is energy-intensive. Bitcoin and pre-Merge Ethereum use PoW. The difficulty adjusts to maintain target block times regardless of total network hash power.
