}Get a Block Transaction
Get a transaction in a block by its Transaction Identifier. This endpoint should only be used when querying a node for a block does not return all transactions contained within it. All transactions returned by this endpoint must be appended to any transactions returned by the /block method by consumers of this data. Fetching a transaction by hash is considered an Explorer Method (which is classified under the Future Work section). This method can be used to let consumers to paginate results when the block transactions count is too big to be returned in a single BlockResponse. Calling this endpoint requires reference to a BlockIdentifier because transaction parsing can change depending on which block contains the transaction. For example, in Bitcoin it is necessary to know which block contains a transaction to determine the destination of fee payments. Without specifying a block identifier, the node would have to infer which block to use (which could change during a re-org). Implementations that require fetching previous transactions to populate the response (ex: Previous UTXOs in Bitcoin) may find it useful to run a cache within the Rosetta server in the /data directory (on a path that does not conflict with the node).

A BlockTransactionRequest is used to fetch a Transaction included in a block that is not returned in a BlockResponse.
The network_identifier specifies which network a particular object is associated with.

"bitcoin"
If a blockchain has a specific chain-id or network identifier, it should go in this field. It is up to the client to determine which network-specific identifier is mainnet or testnet.
"mainnet"
In blockchains with sharded state, the SubNetworkIdentifier is required to query some object on a specific shard. This identifier is optional for all non-sharded blockchains.
The block_identifier uniquely identifies a block in a particular network.
The transaction_identifier uniquely identifies a transaction in a particular network and block or in the mempool.

Any transactions that are attributable only to a block (ex: a block event) should use the hash of the block as the identifier.

Response
Expected response to a valid request
A BlockTransactionResponse contains information about a block transaction.
Transactions contain an array of Operations that are attributable to the same TransactionIdentifier.

Operations contain all balance-changing information within a transaction. They are always one-sided (only affect 1 AccountIdentifier) and can succeed or fail independently from a Transaction. Operations are used both to represent on-chain data (Data API) and to construct new transactions (Construction API), creating a standard interface for reading and writing to blockchains.

The operation_identifier uniquely identifies an operation within a transaction.

The operation index is used to ensure each operation has a unique identifier within a transaction. This index is only relative to the transaction and NOT GLOBAL. The operations in each transaction should start from index 0. To clarify, there may not be any notion of an operation index in the blockchain being described.
x >= 05
Some blockchains specify an operation index that is essential for client use. For example, Bitcoin uses a network_index to identify which UTXO was used in a transaction. network_index should not be populated if there is no notion of an operation index in a blockchain (typically most account-based blockchains).
x >= 00
Type is the network-specific type of the operation. Ensure that any type that can be returned here is also specified in the NetworkOptionsResponse. This can be very useful to downstream consumers that parse all block data.
"Transfer"
Restrict referenced related_operations to identifier indices < the current operation_identifier.index. This ensures there exists a clear DAG-structure of relations. Since operations are one-sided, one could imagine relating operations in a single transfer or linking operations in a call tree.

[{ "index": 1 }, { "index": 2 }]Status is the network-specific status of the operation. Status is not defined on the transaction object because blockchains with smart contracts may have transactions that partially apply (some operations are successful and some are not). Blockchains with atomic transactions (all operations succeed or all operations fail) will have the same status for each operation. On-chain operations (operations retrieved in the /block and /block/transaction endpoints) MUST have a populated status field (anything on-chain must have succeeded or failed). However, operations provided during transaction construction (often times called "intent" in the documentation) MUST NOT have a populated status field (operations yet to be included on-chain have not yet succeeded or failed).
"Reverted"
The account_identifier uniquely identifies an account within a network. All fields in the account_identifier are utilized to determine this uniqueness (including the metadata field, if populated).

The address may be a cryptographic public key (or some encoding of it) or a provided username.
"0x3a065000ab4183c6bf581dc1e55a605455fc6d61"
An account may have state specific to a contract address (ERC-20 token) and/or a stake (delegated balance). The sub_account_identifier should specify which state (if applicable) an account instantiation refers to.

The SubAccount address may be a cryptographic value or some other identifier (ex: bonded) that uniquely specifies a SubAccount.
"0x6b175474e89094c44da98b954eedeac495271d0f"
If the SubAccount address is not sufficient to uniquely specify a SubAccount, any other identifying information can be stored here. It is important to note that two SubAccounts with identical addresses but differing metadata will not be considered equal by clients.
Blockchains that utilize a username model (where the address is not a derivative of a cryptographic public key) should specify the public key(s) owned by the address in metadata.
Amount is some Value of a Currency. It is considered invalid to specify a Value without a Currency.

Value of the transaction in atomic units represented as an arbitrary-sized signed integer. For example, 1 BTC would be represented by a value of 100000000.

Currency is composed of a canonical Symbol and Decimals. This Decimals value is used to convert an Amount.Value from atomic units (Satoshis) to standard units (Bitcoins).

Canonical symbol associated with a currency.
"BTC"
Number of decimal places in the standard unit representation of the amount. For example, BTC has 8 decimals. Note that it is not possible to represent the value of some currency in atomic units that is not base 10.
x >= 08
Any additional information related to the currency itself. For example, it would be useful to populate this object with the contract address of an ERC-20 token.
{ "Issuer": "Satoshi" }CoinChange is used to represent a change in state of a some coin identified by a coin_identifier. This object is part of the Operation model and must be populated for UTXO-based blockchains. Coincidentally, this abstraction of UTXOs allows for supporting both account-based transfers and UTXO-based transfers on the same blockchain (when a transfer is account-based, don't populate this model).

CoinActions are different state changes that a Coin can undergo. When a Coin is created, it is coin_created. When a Coin is spent, it is coin_spent. It is assumed that a single Coin cannot be created or spent more than once.
