 ## Epochs
-Operation of the Sui network is temporally partitioned into non-overlapping, fixed-duration (e.g. 24-hour) *epochs*. During a particular epoch, the set of authorities participating in the network is fixed. At an epoch boundary, reconfiguration occurs and can change the set of authorities participating in the network and their voting power. Conceptually, reconfiguration starts a new instance of the Sui protocol with the previous epoch's final state as [genesis](wallet.md#genesis) and the new set of authorities as the operators.

 ## Committees
-A *committee* is a set of authorities whose combined voting power is >2/3 of the total during a particular epoch. For example, in a Sui instance operated by four authorities that all have the same voting power, any group containing three authorities is a committee.

-The committee size of >2/3 is chosen to ensure *[Byzantine fault](https://en.wikipedia.org/wiki/Byzantine_fault) tolerance (BFT)*. As we will see, an authority will  commit a transaction (i.e., durably store the transaction and update its internal state with the effects of the transaction) only if it is accompanied by cryptographic signatures from a committee. We call the combination of the transaction and the committee signatures on its bytes a *certificate*. The policy of  committing only certificates ensures Byzantine fault tolerance: if <2/3 of the authorities faithfully follow the protocol, they are guaranteed to eventually agree on both the set of committed certificates and their effects.

 ## Write requests
-An authority can handle two types of write requests: transactions and certificates. At a high level, a client:
-* communicates a transaction to a quorum of authorities to collect the signatures required to form a certificate.
-* submits a certificate to an authority to commit state changes on that authority.
+A validator can handle two types of write requests: transactions and certificates. At a high level, a client:
+* communicates a transaction to a quorum of validators to collect the signatures required to form a certificate.
+* submits a certificate to a validator to commit state changes on that validator.
 
 ### Transactions
-When an authority receives a transaction from a client, it will first perform transaction validity checks (e.g., validity of the sender's signature). If the checks pass, the authority will sign the transaction bytes and return the signature to the client. The client repeats this process with multiple authorities until it has collected signatures on its transaction from a committee, thereby forming a certificate.

If the checks pass, the validator will sign the transaction bytes and return the signature to the client. The client repeats this process with multiple validators until it has collected signatures on its transaction from a committee, thereby forming a certificate.
 
-Note that the process of collecting authority signatures on a transaction into a certificate and the process of submitting certifcates can be performed in parallel. The client can simultaneously broadcast transactions/certificates to an arbitrary number of authorities. Alternatively, a client can outsource either or both of these tasks to a third-party service provider. This provider must be trusted for liveness (e.g., it can refuse to form a certificate), but not for safety (e.g., it cannot change the effects of the transaction).

 ### Certificates
-Once the client forms a certificate, it submits the certificate to an authority, which will perform certificate validity checks (e.g., ensuring the signers are authorities in the current epoch, and the signatures are cryptographically valid). If the checks pass, the auhority will execute the transaction inside the certificate. Execution of a transaction will either succeed and commit all of its effects to the ledger, or abort (e.g., due to an explicit `abort` instruction, a runtime error such as divison by zero, or exceeding the maximum gas budget) and have no effects other than debiting the transaction's gas input. In either case, the transaction will durably store the certificate indexed by the hash of its inner transaction.

-As with transactions, we note that the process of sharing a certificate with authorities can be parallelized and (if desired) outsourced to a third-party service provider. A client should broadcast its certificate to >1/3 of the authorities to ensure that (up to BFT assumptions) at least one honest authority has executed and committed the certificate. Other authorities may learn about the certificate via inter-authority state sync or via client-assisted state sync.

-What we sequence using consensus is certificates of transactions. These represent transactions that have already been presented to 2/3 of authorities that checked that all their owned objects are available to be operated on and signed the transaction. Upon a certificate being sequenced, what we do is set the *lock* of the shared objects at the next available version to map to the execution of that certificate. So for example if we have a shared object X at version 2, and we sequence certificate T, we store T -> [(X, 2)]. That is all we do synchronously when we reach consensus, and as a result we are able to ingest a lot of sequenced transactions.

 Now, once this is done we can process all certificates that had their locks set, on one or multiple cores (currently). Obviously, transactions for earlier versions of objects need to be processed first (causally), and that reduces the degree of concurrency. Both the read and write set is determined by the transaction itself, and not dynamically based on the contents of the object at a specific version (not currently).

 There are a few different ways to concisely refer to an object without specifying its full contents and metadata, each with slightly different use cases:
 * ID: the globally unique ID of the object mentioned above. This is a stable identifier for the object across time, and is useful for querying the current state of an object or describing which object was transferred between two addresses.
 * Versioned ID: an (ID, version) pair. This describes the state of the object at a particular point in the object's history, and is useful for asking what the value of the object was at some point in the past or determining how fresh some view of an object is now.
-* Object Reference: an (ID, version, object digest) triple. The object digest is the hash of the object's contents and metadata.
