Aptos Documentation

Aptos Blockchain

These pages explain how Aptos works: accounts and resources, how transactions change state, how Move and Block-STM execute those transactions, and how validators, staking, and governance keep the network running.

For implementation details, read the Aptos white paper, the research papers, and the aptos-core source. For hands-on work, start with Your First Transaction and the Move Book.

Blockchain fundamentals

Section titled “Blockchain fundamentals”
Aptos White Paper Read the design principles behind Aptos: Move, pipelined execution, and on-chain upgrades.
Blockchain Deep Dive Follow a transaction from REST submission through mempool, consensus, execution, and commit.
Blocks See how Aptos batches transactions into blocks, including system transactions and epochs.
The Move Language Learn Move's resource model, Aptos-specific features, and how it compares with other VMs.

Execution and transactions

Section titled “Execution and transactions”
Transactions and States Understand transaction contents, lifecycle states, proofs, and the versioned ledger.
Transaction Payloads and BCS Inspect entry function, script, multisig, orderless, and encrypted payload encodings.
Execution See how Block-STM executes transactions in parallel without declared access lists.
Gas and Storage Fees Learn how execution, IO, and storage fees are charged and refunded.
Computing Transaction Gas Break down instruction, IO, storage, and payload gas parameters.
Events Emit and query module events, and migrate off deprecated EventHandle streams.

Accounts and resources

Section titled “Accounts and resources”
Accounts Cover addresses, authentication keys, key rotation, sequence numbers, and orderless nonces.
Resources See how Move resources, objects, and modules store on-chain state.

Network and nodes

Section titled “Network and nodes”
Validator Nodes Learn how validators run consensus, execute blocks, and persist ledger state.
Fullnodes Run a replica of ledger state, serve the REST API, and forward transactions.
Node Networking and Sync Map validator, VFN, and PFN topology, and how state sync keeps nodes current.

Staking and governance

Section titled “Staking and governance”
Staking Stake APT, join the validator set, and earn epoch rewards in the owner-operator-voter model.
Delegated Staking Pool stake from many delegators so a validator can meet the minimum stake.
Governance Create, vote on, and resolve on-chain proposals that upgrade Aptos.
Section titled “Related guides”
