CHANGELOG.md

# CHANGELOG

## v201.0.7

Namada apps v201.0.7

### IMPROVEMENTS

- Changed RocksDB compaction style to "Level" to avoid stalling on diffs
  column family. ([\#4946](https://github.com/namada-net/namada/pull/4946))

## v201.0.6

Namada apps v201.0.6

### BUG FIXES

- Fix refund when timeout on unlimited channel
  ([\#4822](https://github.com/namada-net/namada/issues/4822))
- Fixed state loading from DB to ignore tx gas map from previous block
  in line with its removal from in-memory state after block commit.
  ([\#4843](https://github.com/namada-net/namada/pull/4843))
- Integrate an updated `nam-bellperson` that fixes issues in wasm,
  namely the usage of `std::time::Instant`, which has been replaced
  with `wasmtimer::std::Instant`. Moreover, silence a lot of the
  `INFO` log lines previously sent to the CLI, when generating proofs.
  ([\#4878](https://github.com/namada-net/namada/pull/4878))

### FEATURES

- Extends the `ShieldedWallet` to also compile the
  history of shielded transactions if requested.
  ([\#4705](https://github.com/anoma/namada/pull/4705))
- Added support for MASP frontend providers sustainability fees.
  ([\#4790](https://github.com/anoma/namada/pull/4790))

### IMPROVEMENTS

- Removed handling of failed atomic batches from `handle_inner_tx_results` that
  was never hit. ([\#4450](https://github.com/namada-net/namada/issues/4450))
- Querying the conversion state becomes more difficult as nodes progress
  to higher and higher epochs. For instance, on a mainnet clone running on
  accelerated epochs, client queries for conversions always timeout (even after
  modifying timeout_broadcast_tx_commit) when the node goes beyond a certain
  MASP epoch. This happens because the conversion state grows linearly with
  the MASP epoch counter. This PR attempts to address this problem by making
  the conversions RPC endpoint require that clients specify the MASP epoch
  they want conversions from. This implies two things: first the size of the
  response from the conversions RPC endpoint should now be constant (equal to
  the number of tokens in the shielded rewards program), and second a client
  requiring all conversions now has to do a separate query for each MASP epoch.
  ([\#4776](https://github.com/namada-net/namada/pull/4776))
- Optimize shielded sync and shielded wallet layout.
  ([\#4785](https://github.com/anoma/namada/pull/4785))
- The masp now uses the bellperson backend to synthesize circuits and build zk
  proofs. Benchmarking this indicates substantial speed ups in proving time.
  ([\#4817](https://github.com/namada-net/namada/pull/4817))
- Updated tiny-hderive crate to replace unmaintained memzero crate with zeroize.
  ([\#4818](https://github.com/namada-net/namada/pull/4818))
- Closes #4714
  - When dry-running, dummy signatures are used in
    txs
  - Validation does not perform signature checks when dry-running
  
I have tested that the gas estimation hasn't changed between dry-running
with signatures and with dummies. It is curious however that in both cases there is a small discrepancy between dry-running and the actual tx.
([\#4714](https://github.com/namada-net/namada/issues/4714))

### SDK

- Updated the transaction building process to avoid using MASP conversions with
  no rewards. ([\#4789](https://github.com/namada-net/namada/issues/4789))
- Reworked SDK wrapping and signatures, including some breaking changes.
  More specifically:
  - The wrapper arguments have been extracted into a separate type and their
    presence signals the need to wrap the tx
  - The dump and dry-run arguments have been turned into enumerations
  - The wrapper signer data has been removed from SigningTxData and moved into
    SigningWrapperData
  - Simplified the interface of aux_signing_data
  - Removed redundant dispatcher functions
  - Prevent casting from a wrapped to a raw transaction type
  - Prevent submitting an unwrapped transaction
  - Avoided passing the MASP internal address as a transaction's owner
  - Updated the interface of build_batch
  - Removed the owner for reveal_pk

  in MASP transactions. ([\#4748](https://github.com/anoma/namada/pull/4748))

### MISCELLANEOUS

- Updated to Rust edition 2024 and increased the MSRV to 1.85.
  ([\#4523](https://github.com/anoma/namada/pull/4523))

### TESTING

- Avoid flakiness in IBC e2e tests
  ([\#4553](https://github.com/anoma/namada/issues/4553))

## libs-v0.251.0

Namada libs v0.251.0 Consensus and API breaking release.

### BUG FIXES

- Fix to receive IBC denom whose base token includes slash
  ([\#4643](https://github.com/anoma/namada/issues/4643))
- Fixed a possible overflow of the masp expiration height in the SDK.
  ([\#4725](https://github.com/anoma/namada/pull/4725))
- Allow to execute WASM with a tx payload that doesn't fit into the initial WASM
  memory. ([\#4729](https://github.com/anoma/namada/pull/4729))
- Validate the base denom in MsgTransfer

  viewing keys on the hardware wallet to save screen space.
  ([\#4436](https://github.com/anoma/namada/pull/4436))
- Forbid targeting MASP payment addresses in IBC transfers.
  ([\#4593](https://github.com/anoma/namada/pull/4593))
- Currently, the shielded wallet attempts to find a file and deserialize it, both of which are fallible. Upon failure, 
  a default (empty) wallet is created. This is fine if the file is missing, but causes unexpeceted behavior when we've changed
  the wallet format and deserialize fails. This PR changes the logic to the following:

  - If the file is missing, use a default
  - If deserialization fails, try to run a migration (this requires versioning shielded wallets)
  - If deserializing / migration fails, error out explicitly
  
  ([\#4664](https://github.com/anoma/namada/pull/4664))
 - Conversions are cached when performing Masp balance queries. Futhermore, the decoded asset type cache is used more
 - effectively. Care must be taken to clear the masp conversions cache on load if the masp epoch has changed. If the 
 - masp epoch changes during a balance query, it may produce invalid output. However, repeating the query after the epoch
 - has completed will yield the correct result. The new cache resides on the shielded wallet, so a migration has been added.

 ([\#4671](https://github.com/anoma/namada/pull/4671))
- Perform wasm gas accounting using mutable global, to avoid frequent host/guest
  vm context switches. ([\#4685](https://github.com/anoma/namada/pull/4685))
 - When using the ledger client, we update witness maps manually. We now add notes to the witness map only if there were successfully trial decrypted. ([\#2693](https://github.com/anoma/namada/pull/4693))
- Add backoff sleep between MASP indexer client failed requests.
  ([\#4702](https://github.com/anoma/namada/pull/4702))
- Added a VP check that gov updated parameters are readable.
  ([\#4708](https://github.com/anoma/namada/pull/4708))
- Allow bech32 encoding of MASP address in shielded receive middleware.
  ([\#4722](https://github.com/anoma/namada/pull/4722))
- Improve the UX of Osmosis swaps in various ways. Moreover, start encoding the
  MASP address with `bech32`, rather than `bech32m`, when shielding the output
  of the trade. ([\#4723](https://github.com/anoma/namada/pull/4723))

### MISCELLANEOUS

- Make CometBFT max_tx_bytes configurable
  ([\#4712](https://github.com/anoma/namada/issues/4712))

  ([\#4594](https://github.com/anoma/namada/pull/4594))
- Improved the UX for shielded fee payment.
  ([\#4619](https://github.com/anoma/namada/pull/4619))
- The `signatures` and `gas-signature` arguments are now avilable only for
  `custom` transactions. If a gas signature is provided then no gas payer is
  allowed. ([\#4625](https://github.com/anoma/namada/pull/4625))
- Compute transaction change to a shielded account only after all shielded
  inputs from it have been constructed. The intent of this is to reduce wasted
  change. ([\#4651](https://github.com/anoma/namada/pull/4651))
- Limit the number of unique transfer targets (sources + targets) to 20, in
  `tx_transfer`. ([\#4659](https://github.com/anoma/namada/pull/4659))
- Optinmized the PoS claim rewards tx to use less gas.
  ([\#4666](https://github.com/anoma/namada/pull/4666))

## v0.43.0

Namada 0.43.0 is a minor relasing improving shielded sync and addressing some pre-genesis flow issues.

### BUG FIXES

- Fix genesis bonds from implicit accounts. Now, only addresses
  of the form `tnam1...` are supported in `balances.toml`.
  ([\#3645](https://github.com/anoma/namada/pull/3645))

### FEATURES

 - Partially addresses Issue [\#2900](https://github.com/anoma/namada/issues/2900). Viewing and spending keys can now
   be given birthdays in the form of block heights which are loaded into 
   shielded sync. Shielded sync will not try to decrypt a block before a 
   keys birthday with said key. ([\#3653](https://github.com/anoma/namada/pull/3653))
- The command `namadan utils test-genesis` now accepts `--check-can-sign`
  multi-arg that can be used with genesis addresses and/or public keys to
  verify that a pre-genesis wallet in the base directory is able to sign
  with the keys associated with the addresses or with the keys themselves.
  ([\#3660](https://github.com/anoma/namada/pull/3660))

### IMPROVEMENTS

- Removed parallel gas accounting.
  ([\#3615](https://github.com/anoma/namada/pull/3615))
- Improve governance client side validation.
  ([\#3629](https://github.com/anoma/namada/pull/3629))

  action. ([\#3632](https://github.com/anoma/namada/pull/3632))
- Do not load context for `namadan utils test-genesis` command.
  ([\#3652](https://github.com/anoma/namada/pull/3652))
- Speeds up client commands on networks with massive balances.toml
  files. Previously, to retrieve the native token of some network,
  we had to parse these giant files. Now, we only parse the
  necessary genesis toml files required to retrieve the native token.
  ([\#3655](https://github.com/anoma/namada/pull/3655))

### SDK

- Parallelize the shielded sync implementation in Namada.
  ([\#3578](https://github.com/anoma/namada/pull/3578))

  ([\#3593](https://github.com/anoma/namada/pull/3593))

### IMPROVEMENTS

- Added two new crates, namada_vm and namada_vp and removed namada crate that
  contained various loosely related code. Moved the native VP implementations
  to the relevant crates and replaced their cross-dependencies with dependency-
  injection. ([\#3402](https://github.com/anoma/namada/pull/3402))
- Replaced cross-system dependencies in namada_shielded_token crate with
  dependency-injection. ([\#3466](https://github.com/anoma/namada/pull/3466))

  addresses' vps. ([\#3312](https://github.com/anoma/namada/issues/3312))
 - Implements phase 1 of Issue [\#3385](https://github.com/anoma/namada/issues/3385)
   - When fetching notes, connections and related failures should not halt shielded sync. Instead, the process
     should be restarted
   - If fetching is interrupted, the data fetched should be persisted locally so that progress isn't lost.

      ([\#3498](https://github.com/anoma/namada/pull/3498))
- Improved the interface of the gas type. Removed the duplicated gas used from
  events. ([\#3428](https://github.com/anoma/namada/pull/3428))
- Implement the phase 2 masp shielded sync client. This client uses
  a [`namada-masp-indexer`](https://github.com/anoma/namada-masp-
  indexer) instance to query the state of the shielded context.
  ([\#3456](https://github.com/anoma/namada/pull/3456))

  running the check for a given proposed block more than once.
  ([\#3473](https://github.com/anoma/namada/pull/3473))
- Expanded the scope of test vector generation and updated outdated components
  of the test vector code. ([\#3494](https://github.com/anoma/namada/pull/3494))

  We now enforce a string subset of this format, to guarantee deterministic
  serialization. ([\#3389](https://github.com/anoma/namada/pull/3389))
- Fix to decode ibc-rs transfer messages
  ([\#3404](https://github.com/anoma/namada/issues/3404))
- Add replay protection to MASP-IBC transactions.
  ([\#3409](https://github.com/anoma/namada/pull/3409))

  requires `--shell` with one of:
  -  bash
  - elvish
  - fish
  - powershell
  - zsh
  - nushell

  To use in e.g. bash, run `namada complete --shell bash > /usr/share/bash-completion/completions/namada.bash`.

   - Add the ability to create chunkable snapshots to our rocksdb implementation
   - Spawn a background task to create snapshots are certain blockheights

   Specifically adds a config parameter that indicates after how many blocks a 
   snapshot should be created. If set, then on the corresponding calls to commit,
   a background task is spun up that takes a snapshot of rocksDB and writes it
   in a convenient format to a file. This file contains metadata of how to be 
   broken up into chunks. Once a new snapshot is created, older snapshots are
   removed. ([\#3383](https://github.com/anoma/namada/pull/3383))
 - Addresses the third point and part of the fourth point of Issue
   [\#3307](https://github.com/anoma/namada/issues/3307)

  - `transfer` (shielded transfer)
  - `transparent-transfer`
  - `shield` (from transparent to shielded)
  - `unshield` (from shielded to transparent)
  ([\#3297](https://github.com/anoma/namada/pull/3297))
- Avoid growing wasm memory when performing read-only accesses.
  ([\#3315](https://github.com/anoma/namada/pull/3315))

  the transaction. ([\#2934](https://github.com/anoma/namada/pull/2934))
- Change the return type of a VP's predicate function to a Result of unit or
  some error. In case Namada users perform invalid state changes, they should
  be met with more descriptive error messages explaining the cause of their tx's
  rejection. ([\#2940](https://github.com/anoma/namada/pull/2940))
- Return error messages from tx execution, instead of aborting execution with no
  context. ([\#2958](https://github.com/anoma/namada/pull/2958))

and runs them through init_chain. All errors are collected into a report. ([\#2255](https://github.com/anoma/namada/pull/2255))
- The wallet CLI structure has been significantly reworked and simplified.
  Alias argument is now obligatory for key generation / derivation
  commands. Feature of raw (non-HD) key generation has been restored,

  require valid signature(s) for unknown storage changes.
  ([\#2213](https://github.com/anoma/namada/pull/2213))
- Allowed the unshielding of previous epochs assets from the masp.
  ([\#2222](https://github.com/anoma/namada/pull/2222))
- Fee amounts in transaction wrappers are now denominated to facilitate hardware
  wallet support. ([\#2245](https://github.com/anoma/namada/pull/2245))
- Refactor the PoS crate by breaking up the lib and tests code into smaller
  files. ([\#2253](https://github.com/anoma/namada/pull/2253))

### IMPROVMENTS

- Previously, a hardcoded set of tokens were expected to be used in Masp conversions.
  If these tokens did not have configs in genesis, this would lead to a panic after the first
  epoch change. This PR fixes this to use the tokens found in genesis belonging to the MASP
  rewards whitelist instead of hardcoding the tokens.
  ([\#2285](https://github.com/anoma/namada/pull/2285))

## v0.28.2

Namada 0.28.2 is a patch release that fixes a stack overflow issue for nodes.

### BUG FIXES

- Fixed DB prefix iterators to avoid iterators with key that don't match the
  given prefix, which was triggering recursive call that was growing stack with
  every new applied tx and on reading state from disk on start-up. Replaced
  recursion from RocksDB that was growing stack size with a loop.
  ([\#2325](https://github.com/anoma/namada/pull/2325))

## v0.28.1

Namada 0.28.1 is a patch release that makes improvements to the MASP, SDK, merkle trees, and chain initialization conditions.

  ([\#1993](https://github.com/anoma/namada/pull/1993))
- Fix Ethereum event validation/state updates when more than one validator is
  running the chain ([\#2035](https://github.com/anoma/namada/pull/2035))
- Fix possible underflow in MASP rewards calculation.
  ([\#2230](https://github.com/anoma/namada/pull/2230))

### IMPROVEMENTS

Allow  the ethereum oracle to be activated / deactivated via config 
updates sent from ledger. This allows governance to shut down the 
ledger without restarts. Otherwise, disconnecting from Ethereum will
result in the ledger crashing.
([\#1764](https://github.com/anoma/namada/pull/1764))
- Prune merkle tree of bridge pool
  ([\#2110](https://github.com/anoma/namada/issues/2110))

  Improved signing of pre-genesis transactions to use the same format as
  regular transactions. Genesis token balances now can be directly assigned to
  established addresses. ([\#2186](https://github.com/anoma/namada/pull/2186))
- Combined the user and the validator VP into one.
  ([\#2202](https://github.com/anoma/namada/pull/2202))
- Charge gas for network usage.
  ([\#2205](https://github.com/anoma/namada/pull/2205))
- A new `tx_become_validator` replaces `tx_init_validator`. This tx doesn't
  initialize a new account and instead it modifies an existing established
  address to become a validator. This currently requires that there are no
  delegations on the source account before it can become a validator (if there
  are some, they have to be unbonded, but they don't have to be withdrawn).
  A new client command `become-validator` is added that requires an `--address`.
  The client command `init-validator` is kept for convenience and updated to
  send `tx_init_account` tx before `tx_become_validator`.
  ([\#2208](https://github.com/anoma/namada/pull/2208))

  failure, some more checked arithmetics, aesthetic code cleanup, and fixing a
  bug in is_delegator. ([\#2178](https://github.com/anoma/namada/pull/2178))
- Added type tags to transactions to enable hardware wallets
  to fully decode transactions even after minor Namada updates.
  ([\#2182](https://github.com/anoma/namada/pull/2182))
- Save MASP conversion state to the state storage instead of the diffs
  ([\#2189](https://github.com/anoma/namada/issues/2189))

- Introduced a new ledger sub-command: `run-until`. Then, at the provided block
  height, the node will either halt or suspend. If the chain is suspended, only
  the consensus connection is suspended. This means that the node can still be
  queried. This is useful for debugging purposes.
  ([#1189](https://github.com/anoma/namada/pull/1189))

### FEATURES

- Allow to set the native token via genesis configuration.
  ([#582](https://github.com/anoma/namada/pull/582))
- Added a validity predicate for implicit accounts. This is set in
  protocol parameters and may be changed via governance. Additionally,
  added automatic public key reveal in the client that use an implicit
  account that hasn't revealed its PK yet as a source. It's also
  possible to manually submit reveal transaction with  client command
  ([#592](https://github.com/anoma/namada/pull/592))
- PoS: Removed staking reward addresses in preparation of auto-staked rewards
  system. ([#687](https://github.com/anoma/namada/pull/687))
- Allow to set validator's commission rates and a limit on change of commission
  rate per epoch. Commission rate can be changed via a transaction authorized
  by the validator, but the limit is immutable value, set when the validator's
  account is initialized. ([#695](https://github.com/anoma/namada/pull/695))
- Optimize the PoS code to depend only on bonded stake, removing
  the VotingPower(Delta) structs. This mitigates some previous
  information loss in PoS calculations. Instead, the notion of
  voting power is only relevant when communicating with Tendermint.
  ([#707](https://github.com/anoma/namada/pull/707))
- Update the set of parameters in the PoS system according to the
  latest spec and standardizes the use of the rust_decimal crate
  for parameters and calculations that require fractional numbers.

  transaction results with query endpoints to the events store.
  ([#674](https://github.com/anoma/namada/pull/674))
- Refactored governance code to use storage_api.
  ([#719](https://github.com/anoma/namada/pull/719))
- Public parts of shared `namada` crate have been split up into a
  `namada_core` crate. The `namada_proof_of_stake`, `namada_vp_prelude`
  and `namada_tx_prelude` crates now depend on this `namada_core` crate.
  ([#733](https://github.com/anoma/namada/pull/733))

## v0.4.0

Anoma 0.4.0 is a scheduled minor release, released 31 January 2022.

### BUG FIXES

- Matchmaker: Fix a matchmaker's state management via a raw pointer
  that was causing segfaults in the matchmaker in release build.
  ([#806](https://github.com/anoma/anoma/pull/806))

### CI

- Build Linux package directly from tagged releases, and upload wasm from tags.
  ([#801](https://github.com/anoma/anoma/pull/801))

### FEATURES

- Client/Ledger: Added a flag  to allow to indicate that client should exit once
  the transaction is in mempool without waiting for it to be applied in a block.
  ([#403](https://github.com/anoma/anoma/issues/403))
- Ledger: Emit and validate IBC events from transactions.
  ([#480](https://github.com/anoma/anoma/issues/480))
- Add `anomac tx-result` command to query the result of a transaction given a
  transaction hash. ([#634](https://github.com/anoma/anoma/issues/634))
- Ledger: Use IBC messages from ibc-rs crate to be used in the relayer.
  ([#699](https://github.com/anoma/anoma/issues/699))
- Ledger: Added [fungible token transfer](https://github.com/cosmos/ibc/tree/26299580866b80fbdf0ce8a0691ee19a28176795/spec/app/ics-020-fungible-token-transfer)
  support to IBC validity predicate. 
  ([#823](https://github.com/anoma/anoma/issues/823))

### IMPROVEMENTS

- Ledger: Add IbcActions trait to execute IBC operations
  ([#411](https://github.com/anoma/anoma/issues/411))
- Matchmaker has been separated from intent gossiper node. Multiple
  matchmakers can connect to an intent gossiper node over WebSocket.
  ([#579](https://github.com/anoma/anoma/issues/579))
- Wallet: Ask for encryption password confirmation when generating a new key.
  ([#625](https://github.com/anoma/anoma/issues/625))
- Ledger: Two-layer merkle tree for the IBC proof verification
  ([#671](https://github.com/anoma/anoma/issues/671))
- Testing: Increments network configuration ports used for E2E
  tests and ABCI++ enabled E2E tests to avoid sharing resources.
  ([#717](https://github.com/anoma/anoma/issues/717))
- Matchmaker: compiling and loading matchmakers to and from dylib instead of
  WASM ([#718](https://github.com/anoma/anoma/pull/718))
- Ledger: Coding IBC-related data without Borsh
  ([#734](https://github.com/anoma/anoma/issues/734))

  matchmaker implementation ([#746](https://github.com/anoma/anoma/pull/746))
- Testing: Update to a new branch of property-based state machine testing with
  initial state shrinking. ([#765](https://github.com/anoma/anoma/pull/765))
- Port the Nix build to the new Flakes system.
  ([#770](https://github.com/anoma/anoma/pull/770))
- Client/Utils: Respect wasm directory, when specified and non-default in the
  command. The command now doesn't unpack the network config archive into its
  default directories, if any of them are specified with non-default values.
  ([#813](https://github.com/anoma/anoma/issues/813))
- Install the default token exchange matchmaker implemenetation into
  `~/.cargo/lib` directory when building from source. When not absolute, the
  matchmaker will attempt to load the matchmaker from the same path as where the
  binary is being ran from, from `~/.cargo/lib` or the current working 
  directory. ([#816](https://github.com/anoma/anoma/issues/816))

### MISCELLANEOUS

- Force non-dev build for make build-release, check-release & package
  ([#791](https://github.com/anoma/anoma/pull/791))

## v0.3.1

Anoma 0.3.1 - first maintenance release in the 0.3.x series. Protocol
compatible with 0.3.0, but changes the on-disk storage format - nodes
will need to resync from scratch.

  these on loading last known block's state from persisted state on disk.
  ([#732](https://github.com/anoma/anoma/pull/732))
- Ledger: Handle Unix and Windows interrupt and termination signals to shut down
  cleanly. ([#768](https://github.com/anoma/anoma/issues/768))

  protocol and allow to keep the established peer connections open.
  ([#775](https://github.com/anoma/anoma/pull/775))

### MISCELLANEOUS

- Adds missing nix-shell openssl dependency.
  ([#694](https://github.com/anoma/anoma/pull/694))
- Don't include wasm checksums in the package, since the network configuration
  mechanisms now handle this. ([#731](https://github.com/anoma/anoma/pull/731))
