Private constructorOptional _indexOptional _originReturns commitment for this UTXO
the poseidon hash of [chainId, amount, pubKey, blinding]
the index configured on this UTXO. Output UTXOs generated before they have been inserted in a tree.
the nullifier: hash of [commitment, index, signature] as decimal string where signature = hash([secret key, commitment, index])
the public key used for generating the commitment. If the utxo is configured with a secret_key, this value should be poseidonHash(secret_key)
the secret_key AKA private_key used in the nullifier. this value is used to derive the public_key for the commitment.
Static Private wasmStatic decryptStatic deserializeThe CircomUtxo object implementation of a Utxo.
A string representation of the parts that make up a utxo.
parts[0] - Curve value, e.g. Bn254, Bls381, Ed25519, etc. value represented as string. parts[1] - Backend value, e.g. arkworks or circom. value represented as string. parts[2] - Amount of atomic units, e.g. ETH in wei amounts or DOT in 10^12 decimals. value represented as uint. parts[3] - TypedChainId, the hex value of the calculated typed chain id parts[4] - Blinding, secret random value parts[5] - PublicKey, the "publicKey = hash(privateKey)" value which indicates ownership for a utxo. parts[6] Optional - EncryptionKey, the public key of "publicKey = encryptionScheme(privateKey)" value used for messaging. parts[7] Optional - PrivateKey, the secret key component correlated to the above values. parts[8] Optional - Index, the leaf index if the utxo has been inserted in a merkle tree

Utxos are objects used to represent ownership of value within a VAnchor instance. The input Utxos to a VAnchor transaction represent the spending a previously created Utxo.
