This initial phase is focused on core Bitcoin protocol data:
Script/Address Balances
UTXO Set
Full Transactions w/ Output Availability
Transaction Confirmations
BTC Headers (Last and N)
🏗️ Struct Definitions
UTXO
Represents an unspent transaction output (UTXO).
struct UTXO {
bytes32 txId; // Transaction ID
uint256 index; // Index of the UTXO
uint256 value; // Value in satoshis
bytes scriptPubKey; // Script public key
}
Transaction
Represents a Bitcoin transaction.
struct Transaction {
bytes32 containingBlockHash; // Hash of the containing block
uint256 transactionVersion; // Transaction version
uint256 size; // Transaction size
uint256 vSize; // Virtual size of the transaction
uint256 lockTime; // Lock time
Input[] inputs; // Array of inputs
Output[] outputs; // Array of outputs
uint256 totalInputs; // Total number of inputs in the original transaction
uint256 totalOutputs; // Total number of outputs in the original transaction
bool containsAllInputs; // Indicates if all inputs are contained
bool containsAllOutputs; // Indicates if all outputs are contained
}
Input
Represents a Bitcoin transaction input.
struct Input {
uint256 inValue; // Value spent by the input in satoshis
bytes32 inputTxId; // Transaction ID of the input source
uint256 sourceIndex; // Index of the input in its transaction
bytes scriptSig; // Script signature
uint256 sequence; // Sequence number
uint256 fullScriptSigLength; // Full length of the script signature
bool containsFullScriptSig; // Indicates if the full script signature is contained
}
Output
Represents a Bitcoin transaction output.
struct Output {
uint256 outValue; // Value of the output in satoshis
bytes script; // Output script
string outputAddress; // Output address
bool isOpReturn; // Indicates if the output is an OP_RETURN output
bytes opReturnData; // Data contained in the OP_RETURN output
bool isSpent; // Indicates if the output is spent
uint256 fullScriptLength; // Full length of the output script
bool containsFullScript; // Indicates if the full output script is contained
SpentDetail spentDetail; // Details of the spent output
}
SpentDetail
Represents details of a spent output.
struct SpentDetail {
bytes32 spendingTxId; // Transaction ID of the spending transaction
uint256 inputIndex; // Index of the input in the spending transaction
}
