Original description and commentary can be found there. --- This changeset finishes the first phase of the assumeutxo project. It makes UTXO snapshots loadable via RPC (`loadtxoutset`) and adds `assumeutxo` parameters to chainparams. It contains all the remaining changes necessary to both use an assumedvalid snapshot chainstate and do a full validation sync in the background. This may look like a lot to review, but note that - ~200 lines are a (non-essential) demo shell script - Many lines are functional test, documentation, and relatively dilute RPC code. So it shouldn't be as burdensome to review as the linecount might suggest. - **P2P**: minor changes are made to `init.cpp` and `net_processing.cpp` to make simultaneous IBD across multiple chainstates work. - **Pruning**: implement correct pruning behavior when using a background chainstate - **Blockfile separation**: to prevent "fragmentation" in blockfile storage, have background chainstates use separate blockfiles from active snapshot chainstates to avoid interleaving heights and impairing pruning. - **Indexing**: some `CValidationInterface` events are given with an additional parameter, ChainstateRole, and all indexers ignore events from ChainstateRole::ASSUMEDVALID so that indexation only happens sequentially. - Have `-reindex` properly wipe snapshot chainstates. - **RPC**: introduce RPC commands `loadtxoutset` and (hidden) `getchainstates`. - **Release docs & first assumeutxo commitment**: add notes and a particular assumeutxo hash value for first AU-enabled release. - This will complete the project and allow use of UTXO snapshots for faster node bootstrap. The next phase, if it were to be pursued, would be coming up with a way to distribute the UTXO snapshots over the P2P network. --- ### UTXO snapshots Create your own with `./contrib/devtools/utxo_snapshot.sh`, e.g. ```shell ./contrib/devtools/utxo_snapshot.sh 788000 utxo.dat ./src/bitcoin-cli -datadir=$(pwd)/testdata`) ``` or use the pre-generated ones listed below. - Testnet: **2'500'000** (Sjors): - torrent: `magnet:?xt=urn:btih:511e09f4bf853aefab00de5c070b1e031f0ecbe9&dn=utxo-testnet-2500000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969` - sha256: `79db4b025448cc0ac388d8589a28eab02de53055d181e34eb47391717aa16388` - Signet: **160'000** (Sjors): - torrent: `magnet:?xt=urn:btih:9da986cb27b3980ea7fd06b21e199b148d486880&dn=utxo-signet-160000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969` - sha256: `eeeca845385ba91e84ef58c09d38f98f246a24feadaad57fe1e5874f3f92ef8c` - Mainnet: **800'000** (Sjors): - Note: this needs the following commit cherry-picked in: https://github.com/Sjors/bitcoin/commit/24deb2022b822f22fba9fcbee201e37a83225eb2 - torrent: `magnet:?xt=urn:btih:50ee955bef37f5ec3e5b0df4cf0288af3d715a2e&dn=utxo-800000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969` ### Testing #### For fun (~5min) If you want to do a quick test, you can run `./contrib/devtools/test_utxo_snapshots.sh` and follow the instructions. This is mostly obviated by the functional tests, though. #### For real (longer) If you'd like to experience a real usage of assumeutxo, you can do that too. I've cut a new snapshot at height 788'000 (http://img.jameso.be/utxo-788000.dat - but you can do it yourself with `./contrib/devtools/utxo_snapshot.sh` if you want). Download that, and then create a datadir for testing: ```sh $ cd ~/src/bitcoin # or whatever # get the snapshot $ curl http://img.jameso.be/utxo-788000.dat > utxo-788000.dat # you'll want to do this if you like copy/pasting $ export AU_DATADIR=/home/${USER}/au-test # or wherever $ mkdir ${AU_DATADIR} $ vim ${AU_DATADIR}/bitcoin.conf dbcache=8000 # or, you know, something high blockfilterindex=1 coinstatsindex=1 prune=3000 logthreadnames=1 ``` Obtain this branch, build it, and then start bitcoind: ```sh $ git remote add jamesob https://github.com/jamesob/bitcoin $ git fetch jamesob assumeutxo $ git checkout jamesob/assumeutxo $ ./configure $conf_args && make # (whatever you like to do here) # start 'er up and watch the logs $ ./src/bitcoind -datadir=${AU_DATADIR} ``` Then, in some other window, load the snapshot ```sh $ ./src/bitcoin-cli -datadir=${AU_DATADIR} loadtxoutset $(pwd)/utxo-788000.dat ``` You'll see some log messages about headers retrieval and waiting to see the snapshot in the headers chain. Once you get the full headers chain, you'll spend a decent amount of time (~10min) loading the snapshot, checking it, and flushing it to disk. After all that happens, you should be syncing to tip in pretty short order, and you'll see the occasional `[background validation]` log message go by. In yet another window, you can check out chainstate status with ```sh $ ./src/bitcoin-cli -datadir=${AU_DATADIR} getchainstates ``` as well as usual favorites like `getblockchaininfo`.

and conflicting heights in MarkConflicted 782701ce7d31919dba2241ee43b582d8ae5a2541 test: Test loading wallets with conflicts without a chain (Andrew Chow) 4660fc82a1f5cf6eb6404d5268beef5919581661 wallet: Check last block and conflict height are valid in MarkConflicted (Andrew Chow) Pull request description: `MarkConflicted` assumes that `m_last_block_processed_height` is always valid. However it may not be valid when a chain is not attached, as happens in the wallet tool and during migration. In such situations, when the conflicting height is also negative (which occurs on loading when no chain is available), the calculation of the number of conflict confirms results in a non-negative value which passes the existing check for valid values. This will subsequently hit an assertion in `GetTxDepthInMainChain`. Furthermore, `MarkConflicted` is also only called on loading a transaction whose parent has a stored state of `TxStateConflicted` and was loaded before the child transaction. This depends on the loading order, which for both sqlite and bdb depends on the txids. We can avoid this by explicitly checking that both `m_last_block_processed_height` and `conflicting_height` are non-negative. Both `tool_wallet.py` and `wallet_migration.py` are updated to create wallets with a state that triggers the assertion.

MarkConflicted calculates conflict confirmations incorrectly when both the last block processed height and the conflicting height are negative (i.e. uninitialized). If either are negative, we should not be marking conflicts and should exit early.

The legacy wallet allows to import any raw script (#28126), without checking if it was valid or not. Appending it to the watch-only set. This causes a crash in the migration process because we are only expecting to find valid scripts inside the legacy spkm. These stored scripts internally map to `ISMINE_NO` (same as if they weren't stored at all..). So we need to check for these special case, and take into account that the legacy spkm could be storing invalid not watched scripts. Which, in code words, means `IsMineInner()` returning `IsMineResult::INVALID` for them. Note: To verify this, can run the test commit on top of master. `wallet_migration.py` will crash without the bugfix commit.

In order to still allow paying to arbitrary scriptPubKeys (e.g. for data carrier outputs, or the user hand crafted a raw transaction that they have given to `fundrawtransaction`), `CNoDestination` is changed to contain raw scripts. Additionally, P2PK scripts are now interpreted as a new `PubKeyDestination` rather than `PKHash`. This results in some things that would have given an address for P2PK scripts to no longer do so. This is arguably more correct. `ExtractDestination`'s behavior is slightly changed for the above. It now returns `true` for those destinations that have addresses, so P2PK scripts now result in `false`. Even though it returns false for `CNoDestination`, the script will now be included in that `CNoDestination`.

2023-09-13Bump unconfirmed parent txs to target feerateMurch
When a transaction uses an unconfirmed input, preceding this commit it would not consider the feerate of the parent transaction. Given a parent transaction with a lower ancestor feerate, this resulted in the new transaction's ancestor feerate undershooting the target feerate. This commit changes how we calculate the effective value of unconfirmed UTXOs. The effective value of unconfirmed UTXOs is decreased by the fee necessary to bump its ancestry to the target feerate. This also impacts the calculation of the waste metric: since the estimate for the current fee is increased by the bump fees, unconfirmed UTXOs current fees appear less favorable compared to their unchanged long term fees. This has one caveat: if multiple UTXOs have overlapping ancestries, each of their individual estimates will account for bumping all ancestors.

2023-08-25wallet: accurately account for the size of the witness stackAntoine Poinsot
When estimating the maximum size of an input, we were assuming the number of elements on the witness stack could be encode in a single byte. This is a valid approximation for all the descriptors we support (including P2WSH Miniscript ones), but may not hold anymore once we support Miniscript within Taproot descriptors (since the max standard witness stack size of 100 gets lifted). It's a low-hanging fruit to account for it correctly, so just do it now.
2023-08-25wallet: use descriptor satisfaction size to estimate inputs sizeAntoine Poinsot
Instead of using the dummysigner to compute a placeholder satisfaction, infer a descriptor on the scriptPubKey of the coin being spent and use the estimation of the satisfaction size given by the descriptor directly. Note this (almost, see next paragraph) exactly conserves the previous behaviour. For instance CalculateMaximumSignedInputSize was previously assuming the input to be spent in a transaction that spends at least one Segwit coin, since it was always accounting for the serialization of the number of witness elements. In this commit we use a placeholder for the size of the serialization of the witness stack size (1 byte). Since the logic in this commit is already tricky enough to review, and that it is only a very tiny approximation not observable through the existing tests, it is addressed in the next commit.
2023-08-25descriptor: introduce a method to get the satisfaction sizeAntoine Poinsot
In the wallet code, we are currently estimating the size of a signed input by doing a dry run of the signing logic. This is unnecessary as all outputs we are able to sign for can be represented by a descriptor, and we can derive the size of a satisfaction ("signature") from the descriptor itself directly. In addition, this approach does not scale: getting the size of a satisfaction through a dry run of the signing logic is only possible for the most basic scripts. This commit introduces the computation of the size of satisfaction per descriptor. It's a bit intricate for 2 main reasons: - We want to conserve the behaviour of the current dry-run logic used by the wallet that sometimes assumes ECDSA signatures will be low-r, sometimes not (when we don't create them). - We need to account for the witness discount. A single descriptor may sometimes benefit of it, sometimes not (for instance `pk()` if used as top-level versus if used inside `wsh()`).
