Abstract
|
|
========
|
|
|
|
This proposal defines a new transaction digest algorithm for signature verification from the Sapling network
|
|
upgrade, to account for the presence of Sapling shielded inputs and outputs in transactions.
|
|
|
|
|
|
Motivation
|
|
==========
|
|
|
|
The Sapling network upgrade introduced new shielded inputs and outputs. We want these to be covered by the
|
|
transaction digest algorithm used for signatures, in order to ensure they are correctly bound.
|
|
|
|
|
|
Specification
|
|
=============
|
|
|
|
A new transaction digest algorithm is defined::
|
|
|
|
BLAKE2b-256 hash of the serialization of:
|
|
1. header of the transaction (4-byte little endian)
|
|
2. nVersionGroupId of the transaction (4-byte little endian)
|
|
3. hashPrevouts (32-byte hash)
|
|
4. hashSequence (32-byte hash)
|
|
5. hashOutputs (32-byte hash)
|
|
6. hashJoinSplits (32-byte hash)
|
|
7. hashShieldedSpends (32-byte hash)
|
|
8. hashShieldedOutputs (32-byte hash)
|
|
9. nLockTime of the transaction (4-byte little endian)
|
|
10. nExpiryHeight of the transaction (4-byte little endian)
|
|
11. valueBalance of the transaction (8-byte little endian)
|
|
12. sighash type of the signature (4-byte little endian)
|
|
|
|
13. If we are serializing a transparent input (i.e. this hash is not for a JoinSplit signature,
|
|
Spend authorization signature, or binding signature):
|
|
a. outpoint (32-byte hash + 4-byte little endian)
|
|
b. scriptCode of the input (serialized as scripts inside CTxOuts)
|
|
c. value of the output spent by this input (8-byte little endian)
|
|
d. nSequence of the input (4-byte little endian)
|
|
|
|
The new algorithm is based on the transaction digest algorithm defined in ZIP 143 [#zip-0143]_.
|
|
|
|
The new algorithm MUST be used for signatures created over the Sapling transaction format [#zip-0XXX]_.
|
|
Combined with the new consensus rule that v3 transaction formats will be invalid from the Sapling upgrade
|
|
[#zip-0XXX]_, this effectively means that all transaction signatures from the Sapling activation height will
|
|
use the new algorithm [#zip-0XXX]_.
|
|
|
|
The BLAKE2b-256 personalization field [#BLAKE2-personalization]_ is set to::
|
|
|
|
"ZcashSigHash" || CONSENSUS_BRANCH_ID
|
|
|
|
``CONSENSUS_BRANCH_ID`` is the little-endian encoding of ``BRANCH_ID`` for the epoch of the block containing
|
|
the transaction. [#zip-0200]_ Domain separation of the signature hash across parallel branches provides replay
|
|
protection: transactions targeted for one branch will have invalid signatures on other branches.
|
|
|
|
Transaction creators MUST specify the epoch they want their transaction to be mined in. Across a network
|
|
upgrade, this means that if a transaction is not mined before the activation height, it will never be mined.
|
|
|
|
Semantics of the original sighash types are as in ZIP 143 [#zip-0143]_.
|
|
|
|
Field definitions
|
|
-----------------
|
|
|
|
The items 1, 2, 3, 4, 5, 9, 10, 12, and 13 have the same meaning as in ZIP 143 [#zip-0143]_.
|
|
|
|
6: ``hashJoinSplits``
|
|
`````````````````````
|
|
* If ``vjoinsplits`` is non-empty, ``hashJoinSplits`` is the BLAKE2b-256 hash of the serialization of all
|
|
JoinSplit descriptions (in their canonical v4 transaction serialization format) concatenated with the
|
|
``joinSplitPubKey``;
|
|
|
|
* The BLAKE2b-256 personalization field is set to ``ZcashJSplitsHash``.
|
|
|
|
* Note that while signatures are omitted, the JoinSplit proofs are included in the signature hash, as with
|
|
v1, v2, and v3 transactions.
|
|
|
|
* Otherwise, ``hashJoinSplits`` is a ``uint256`` of ``0x0000......0000``.
|
|
|
|
7: ``hashShieldedSpends``
|
|
`````````````````````````
|
|
|
|
* If ``vShieldedSpend`` is non-empty, ``hashShieldedSpends`` is the BLAKE2b-256 hash of the serialization of
|
|
all Spend Descriptions (in their canonical transaction serialization format minus ``spendAuthSig``);
|
|
|
|
* The BLAKE2b-256 personalization field is set to ``ZcashSSpendsHash``.
|
|
|
|
* Note that the Spend proofs are included in the signature hash, as with JoinSplit proofs in v1, v2, and v3
|
|
transactions.
|
|
|
|
* Otherwise, ``hashShieldedSpends`` is a ``uint256`` of ``0x0000......0000``.
|
|
|
|
8: ``hashShieldedOutputs``
|
|
``````````````````````````
|
|
|
|
* If ``vShieldedOutput`` is non-empty, ``hashShieldedOutputs`` is the BLAKE2b-256 hash of the serialization of
|
|
all Output Descriptions (in their canonical transaction serialization format);
|
|
|
|
* The BLAKE2b-256 personalization field is set to ``ZcashSOutputHash``.
|
|
|
|
* Note that the Output proofs are included in the signature hash, as with JoinSplit proofs in v1, v2, and v3
|
|
transactions.
|
|
|
|
* Otherwise, ``hashShieldedOutputs`` is a ``uint256`` of ``0x0000......0000``.
|
|
|
|
11: ``valueBalance``
|
|
````````````````````
|
|
An 8-byte signed two's-complement little-endian value of the net amount, in zatoshi, exiting the Sapling value
|
|
pool. For clarity, a negative value corresponds to an amount *entering* the Sapling value pool.
|
|
|
|
Notes
|
|
-----
|
|
|
|
The ``hashPrevouts``, ``hashSequence``, ``hashOutputs``, ``hashJoinSplits``, ``hashShieldedSpends``, and
|
|
``hashShieldedOutputs`` calculated in an earlier verification can be reused in other inputs of the same
|
|
transaction, so that the time complexity of the whole hashing process reduces from O(n\ :sup:`2`) to O(n).

Example

|
=======
|
|
|
|
To ensure consistency in consensus-critical behaviour, developers should test their implementations against
|
|
the ZIP 243 test vectors [#test-vectors]_. The first two test vectors are broken out below for clarity. Note
|
|
that 32-byte values below are exactly as the hash function returns, and are not reversed. Further examples can
|
|
be found in the SignatureHash test data [#sighash-tests]_.

Deployment
|
|
==========
|
|
|
|
This proposal is deployed with the Sapling network upgrade. [#zip-0XXX]_
|
|
|
|
|
|
Backward compatibility
|
|
======================
|
|
|
|
This proposal is backwards-compatible with old UTXOs. It is **not** backwards-compatible with older software.
|
|
All transactions will be required to use this transaction digest algorithm for signatures, and so transactions
|
|
created by older software will be rejected by the network.
|
|
|
|
|
