 * [Objects](../build/objects.md) - Sui has programmable objects created and managed by Move packages (a.k.a. smart contracts). Move packages themselves are also objects. Thus, Sui objects can be partitioned into two categories mutable data values and immutable packages.
 * [Transactions](../build/transactions.md) - All updates to the Sui ledger happen via a transaction. This section describes the transaction types supported by Sui and explains how their execution changes the ledger.

 An *accumulator* makes sure the transaction is received by a quorum of validators, collects a quorum of votes, submits the certificate to the validators, and replies to the client. The accumulator enables transactions to be certified. Sui offers a Gateway service that can assume the role of accumulator and collect votes on transactions from validators in Sui, saving end-users bandwidth.
