CHANGELOG

v0.41.0

Namada 0.41.0 is a minor release that primarily improves gas, fixes bugs related to signature verification and a memory leak from a dependency, and includes shielded sync upgrades.

BUG FIXES

• Adds SDK builder to shielded and shielding transfers. (#3518)
• Workaround a leak in wasmer store. (#3529)
• Client fixes that include using the correct total voting power to compute a proposal result and also the correct voting threshold for steward proposals. (#3540)
• Fixed a possible panic in transaction signatures verification missing expected signature(s). (#3543)

CI

• Fixed a broken e2e test for db migrations. Added it to the list of e2e test to be run by the CI. (#3481)

IMPROVEMENTS

• Moved the signature verifications out of the masp vp and into the affected addresses' vps. (#3312)
• Implements phase 1 of Issue #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.

  • A trait for fetching behavior should be added to provide modularity

    (#3498)

• Improved the interface of the gas type. Removed the duplicated gas used from events. (#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)
• Minor improvements to governance and PGF code quality, including template gov proposal jsons and a python script to attach wasm code. (#3471)
• Modified rechecks of process proposal to actually use process_proposal instead of process_txs. Added a caching mechanism to avoid running the check for a given proposed block more than once. (#3473)
• Expanded the scope of test vector generation and updated outdated components of the test vector code. (#3494)
• Removes redundant function. (#3502)
• Bump tendermint-rs to 0.37 (#3506)
• Increased the gas cost for storage occupation and tied it to the other gas costs. (#3510)
• Eliminates the MASP VPs requirement for all debited accounts to sign a Tx. (#3516)
• Rename and split --memo-path into --ibc-shielding-data and --ibc-memo (#3517)

v0.40.0

Namada 0.40.0 is a minor release that makes many important improvements to shielded actions, DB snapshotting capabilities, batched transactions, and much more.

BUG FIXES

• Update native token total supply with MASP rewards. (#3375)
• Increase the lifetime of disposable signing keys from 5 minutes to 1 week. (#3378)
• Our DateTimeUtc type allowed a relaxed representation of RFC3339 strings. We now enforce a string subset of this format, to guarantee deterministic serialization. (#3389)
• Fix to decode ibc-rs transfer messages (#3404)
• Add replay protection to MASP-IBC transactions. (#3409)
• Respect --wasm-dir on init-network. (#3432)
• Fix IBC shielding transfer for the receiver not to be replaced by a malicious relayer (#3438)
• Fixed MASP witness data malleability in the Tx (#3463)
• Fix to extract MASP transaction when IBC shielding transfer (#3488)

FEATURES

• Reworked transparent and masp transfers to allow for multiple sources, targets, tokens and amounts. (#3356)
• Added support for fee payment directly from the MASP pool. (#3393)

IMPROVEMENTS

• Moved up the check on the sapling value balance in the masp vp. (#2721)

• Queries methods now requests TryInto trait bound for block heights to reduce the conversion error. (#2891)

• Miscellaneous code optimizations. (#3192)

• Added a namada complete command to generate shell completions. This command 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. (#3343)

• Remove the max_expected_time_per_block genesis parameter. (#3366)

• Refactored checked assign arithmetic operations to use smooth-operator macro. (#3374)

• Store total MASP rewards and print them in the conversions query. (#3375)

• Remove the check on the maximum number of signatures allowed per transaction (#3380)

• Resolves the first two points of Issue #3307:

  • 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)

• Addresses the third point and part of the fourth point of Issue #3307

  • Adds chunking logic to snapshots
  • Implements the ListSnapshots ABCI call
  • Implements the LoadSnapshotChunk ABCI call

  (#3386)

• Remove the requirement that the proposal voting period is some integer multiple of the minimum voting period. (#3390)

• Include the gas scale as a protocol parameter that is mutable via governance rather than as a hard-coded constant. (#3391)

• Upgrade the library used to communicate with hardware wallet (#3412)

• Index batched txs via their wrapper and commitment hashes. (#3416)

• Moved shielded tx validation out of the SDK crate into shielded token crate. (#3419)

• Enforce an upper limit on the number of PGF stewards allowed to exist at a given time. (#3442)

• Combined the various Transfer formats into one general one. (#3446)

• Introduced a local configuration parameter to allow nodes to rerun the process proposal checks before block finalization. (#3448)

TESTING

• Adds additional test coverage to batch tx events emission, to make sure we correctly build a batch of inner tx events from a batched tx. (#3401)
• Change the IBC E2E testing config (#3455)

IMPROVEMENTS

• The transfer command has been split into:
  • transfer (shielded transfer)
  • transparent-transfer
  • shield (from transparent to shielded)
  • unshield (from shielded to transparent) (#3297)
• Avoid growing wasm memory when performing read-only accesses. (#3315)
• Added a separate epoch tracker for masp to decouple its logic from the rest of the protocol. (#3318)
• Default to the address from local config when the --node argument is not specified for shielded-sync command (#3333)

• Remove last staked ratio and pos inflation amount from Parameters and initialize them in pos genesis initialization. (#2559)
• Only process 1 slash per validator per block height. (#2574)
• Refactor inflation with a standalone PD controller module. Then the PoS and shielded inflation modules are wrappers around this controller. (#2575)
• Instead of having every user tx be executed across two blocks, the first executing a wrapper and the second executing the main payload, this change makes it so that the entire tx is executed in a single block (or rejected). (#2627)
• Only load governance proposals on a new epoch right before execution. Decoupled the logic from the Shell and implemented in the gov crate. (#2630)
• Adds a transaction's code and data section hashes as additional sources of entropy, to compute an established account's address. (#2781)

v0.29.0

Namada 0.29.0 is a minor release that introduces the light SDK, upgrades the MASP and CLI, and includes other fixes and refactors of the PoS, IBC, and Ethereum Birdge modules.

BUG FIXES

• Prevents double-spending in masp by adding a nullifier set. (#2240)
• Updates masp tx to store the notes and the native vp to validate them and the anchors. (#2244)
• Updates the masp vp to validate the convert description's anchor. (#2248)
• Client: Check that transaction is successful before taking further actions. (#2279)
• Non-Namada token can be given to ibc-gen-shielded (#2308)
• Make the ledger wait for genesis before starting up any processes (#2310)

• 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, which was removed in the previous release. Key export / import functionality for both transparent and shielded key kinds has been implemented. Additionally, several other improvements have been made. (#2260)
• IBC transfer from a spending key (#2321)

IMPROVEMENTS

• Emit Bridge pool transfer status update events from FinalizeBlock (#1995)

• Improved validation on transaction's expiration. Added an expiration for MASP transfers. (#2315)

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)

Replaced recursion from RocksDB that was growing stack size with a loop. (#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.

BUG FIXES

v0.28.0

Namada 0.28.0 is a minor release that improves the genesis setup to allow signing with hardware wallet and contains various improvements including validator liveness jailing, accounts simplifications, bug fixes, stability improvements and more.

BUG FIXES

• Fix the start block height of the first epoch. (#1993)
• Fix Ethereum event validation/state updates when more than one validator is running the chain (#2035)
• Fix possible underflow in MASP rewards calculation. (#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)

• Prune merkle tree of bridge pool (#2110)
• Revert the chain ID format by upgrading ibc-rs to 0.48.1 (#2153)
• Changed pre-genesis established addresses to be derived from their data. 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)
• Combined the user and the validator VP into one. (#2202)
• Charge gas for network usage. (#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)
• Increase hardware wallet support in the CLI (#2209)
• Handle errors on loading WASMs from file-system compilation cache. (#2215)

FEATURES

• Added bech32m string encoding for common::PublicKey and DkgPublicKey. (#2088)
• Added --pre-genesis argument to the wallet commands to allow to generate keys, implicit addresses and shielded keys without having a chain setup. If no chain is setup yet (i.e. there's no base-dir or it's empty), the wallet defaults to use the pre-genesis wallet even without the --pre-genesis flag. The pre-genesis wallet is located inside base-dir in pre-genesis/wallet.toml. (#2088)
• Reworked the genesis templates, setup and related utils commands. (#2088)

• Prevent clients from delegating from a validator account to another validator account. (#1263)

FEATURES

• Infrastructure for PoS inflation and rewards. Includes inflation using the PD controller mechanism and rewards based on validator block voting behavior.

In this PR, rewards are calculated and stored, but they are not yet applied to voting powers or considered when unbonding and withdrawing. (#714)
• Implements governance custom proposals (#1056)
• Adds expiration field to transactions (#1123)
• Added a rollback command to revert the Namada state to that of the previous block. (#1187)
• 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)

IMPROVEMENTS

BUG FIXES

• Fixed the PrefixIter order of iteration in the write- log to always match the iteration order in the storage. (#1141)
• Fixed the init-chain handler to stop committing state to the DB as it may be re-applied when the node is shut-down before the first block is committed, leading to an invalid genesis state. (#1182)
• Fixed an issue in which a validator's stake and validator sets data gets into an invalid state (duplicate records with incorrect values) due to a logic error in clearing of historical epoch data. (#1191)

FEATURES

• Added a lazy set collection. (#1196)

IMPROVEMENTS
