Mandel v3.1.0-rc1 Release Notes
Pre-release
This is a RELEASE CANDIDATE for version 3.1.0. The latest STABLE release is v2.0.14.
Release 3.1.0-rc1 includes protocol upgrades enabling contracts to get the current block number and to accelerate various cryptographic computation, as well as many other new features including:
- a new transaction submission API endpoint with full trace of a transaction failure and automatic nodeos-mediated retry;
- nodeos-mediated cache of transaction finality statuses along with a new API endpoint to query the finality status of a transaction;
- the ability to request a nodeos computation of transaction costs without committing the transaction;
- the addition of new options for subjective billing;
- automatic pruning of old entries in block and
state_history_plugin(SHiP) logs; - and, much more.
Read on for details.
Protocol changes
Host functions to accelerate crypto primitives
A new protocol feature CRYPTO_PRIMITIVES has been introduced which upon activation will make 7 new host functions accessible to contracts which are all related to cryptographic computations.
While in theory all of these cryptographic computations could be implemented in WebAssembly code if the transaction was given sufficient time to execute before timing out, leveraging these new host functions may allow for significantly reducing the time it takes to execute the computations because the computations are carried out in native implementation of the host executable. This means some cryptographic functions now become practically accessible to contracts even with typical transaction deadlines in production blockchains, and some others continue to remain accessible but at a lower CPU cost.
In particular, all of these new host functions serve to reduce CPU costs of executing the cryptographic functions available in EVM precompiled contracts.
Arbitrary-precision exponentiation under modulo
Activation of the CRYPTO_PRIMITIVES protocol feature introduces the mod_exp host function which enables modular exponentiation with arbitrary-precision numbers.
Support for the alt_bn128 elliptic curve
Activation of the CRYPTO_PRIMITIVES protocol feature introduces the following three host functions that support elliptic curve math involving the alt_bn128 elliptic curve:
alt_bn128_add: Point addition on the alt_bn128 elliptic curve.alt_bn128_mul: Scalar multiplication on the alt_bn128 elliptic curve.alt_bn128_pair: Bilinear function on groups on the alt_bn128 elliptic curve.
These host functions can support implementations that verify zkSNARKs.
ECDSA uncompressed public key recovery for the secp256k1 elliptic curve
The protocol already supported ECDSA public key recovery for the secp256k1 elliptic curve (and also for the secp256r1 elliptic curve) through the recover_key host function. However, that host function has two limitations. First, it aborts the transaction if an invalid signature is presented rather than returning a failure condition to the caller. Second, it returns the recovered public key in compressed format. And going from a compressed to uncompressed public key requires elliptic curve math which involves compiling in an elliptic curve library into the contract, thus bloating the contract size and increasing CPU time for ECDSA uncompressed public key recovery.
Activation of the CRYPTO_PRIMITIVES protocol features introduces the k1_recover host function which addresses both limitations of recovery_key mentioned above. However, it has its own limitation of only supporting the secp256k1 elliptic curve. There is currently no host function that returns an uncompressed public key from ECDSA recovery using the secp256r1 elliptic curve.
Additional support for hash functions
Activation of CRYPTO_PRIMITIVES protocol feature introduces the following two host functions:
sha3: This host function computes the SHA3-256 hash of an arbitrary byte string. Both the NIST and Keccak variants are supported.blake2_f: This host function implements the compression function F used in the BLAKE2 cryptographic hashing algorithm.
Get current block number from within contracts
A new protocol feature GET_BLOCK_NUM has been introduced which upon activation will make the host function get_block_num accessible to contracts. The get_block_num host function returns the block number (aka block height) of the current block.
New features
New transaction submission API
PRs
New chain_api_plugin endpoint:
-
/v1/chain/send_transaction2(send_transaction_params)struct send_transaction2_params { bool return_failure_trace = true; ///< Embed transaction exceptions into the returned transaction trace bool retry_trx = false; ///< request transaction retry on validated transaction std::optional<uint16_t> retry_trx_num_blocks{}; ///< if retry_trx, report trace at specified blocks from executed or lib if not specified fc::variant transaction; ///< same format as send_transaction };
This new transaction submission API supports returning the full trace of a failed transaction and automatic nodeos-mediated retry if enabled on the node.
When transaction retry is enabled on an API node, it will monitor incoming API transactions and ensure they are resubmitted additional times into the P2P network until they expire or are included in a block.
receipt and except fields of the returned trace.
New configuration args for nodeos:
transaction-retry-max-storage-size-gb- "Maximum size (in GiB) allowed to be allocated for the Transaction Retry feature. Setting above 0 enables this feature."
transaction-retry-interval-sec(defaults to 20)- "How often, in seconds, to resend an incoming transaction to the P2P network if not seen in a block."
transaction-retry-max-expiration-sec(defaults to 90)- "Maximum allowed transaction expiration for retry transactions, will retry transactions up to this value."
p2p-dedup-cache-expire-time-sec(defaults to 10)- "Maximum time in seconds to track transaction for duplicate optimization"
New command line options for cleos:
--use-old-send-rpc- "Use old RPC
/v1/chain/send_transaction, rather than new RPC/v1/chain/send_transaction2"
- "Use old RPC
-t,--return-failure-tracedefaults totrueuse-t falsefor previous behavior- "Return partial traces on failed transactions"
- Note: Automation which depends on cleos to return a non-zero value on transaction failure will instead need to parse the traces or use option
-t false.
--retry-irreversible- "Request node to retry transaction until it is irreversible or expires, blocking call"
--retry-num-blocks- "Request node to retry transaction until in a block of given height, blocking call"
Transaction finality status
PRs
- Added read only transaction status capability,
get_transaction_status, to the Chain API Plugin. Also added support in cleos. (#145) - Added Finality Status storage. Added storage for Finality Status feature and using signals_processor to populate. (#81)
- Added integration tests for finality status. (#189)
New chain_api_plugin endpoint:
-
/v1/chain/get_transaction_status(get_transaction_status_params)struct get_transaction_status_params { transaction_id_type id; //transaction id to status }; struct get_transaction_status_results { string state; std::optional<uint32_t> block_number; std::optional<chain::block_id_type> block_id; std::optional<fc::time_point> block_timestamp; std::optional<fc::time_point> expiration; uint32_t head_number; chain::block_id_type head_id; fc::time_point head_timestamp; uint32_t irreversible_number; chain::block_id_type irreversible_id; fc::time_point irreversible_timestamp; chain::block_id_type last_tracked_block_id; };
When transaction finality status is enabled, the status of a transaction in the node, as well as a snapshot of the current chain state, can be queried. If a transaction is not found for the given transaction id, only the chain status fields and a status of "UNKNOWN" will be provided.
New configuration args for nodeos:
transaction-finality-status-max-storage-size-gb- "Maximum size (in GiB) allowed to be allocated for the Transaction Finality Status feature. Setting above 0 enables this feature."
transaction-finality-status-success-duration-sec(defaults to 180)- "Duration (in seconds) a successful transaction's finality status will remain available from being first identified."
transaction-finality-status-failure-duration-sec(defaults to 180)- "Duration (in seconds) a failed transaction's finality status will remain available from being first identified."
New command line options for cleos:
get transaction-status <id>- "Gets current blockchain state and, if available, transaction information given the transaction id"
Transaction Resource Cost Estimation
PRs
New chain_api_plugin endpoint:
/v1/chain/compute_transaction- accepts existing
send_transaction_params
- accepts existing
Transactions sent to this endpoint will be executed and create a transaction trace, including resource usage, and then will revert all state changes and will not contribute to the subjective billing for the account. If the transaction has signatures, they will be processed, but any failures will be ignored. Transactions which fail will always include the transaction failure trace.
New command line options for cleos:
--read-only- "Specify a transaction is read-only"
Block log & state_history_plugin (SHiP) log pruning
PRs
Two new options block-log-retain-blocks and state-history-log-retain-blocks are available to configure nodeos to periodically prune these logs to the most recent configured blocks. This allows reducing the amount of disk space nodeos uses over time without stopping the node.
Other changes
Upgraded cryptography library libsecp256k1
PRs
The branch of the libsecp256k1 library in use was many years old. The newly adopted version enables significant performance improvements, as well as including bug fixes.
K1 signature key recovery performance improvements:
| CPU | Previous | New |
|---|---|---|
| Intel 9600k | 50 µs | 33 µs |
| AMD 5950X | 51 µs | 35 µs |
(exact performance numbers will vary depending on hardware, OS, and system load)
The library's own unit tests are now incorporated into the suite of tests executed by Mandel.
Subjective billing improvements
PRs
- Implemented additional check against account whitelist in subjective billing. (#84)
- Added "subjective-account-max-failures" option in the Producer Plugin to set the maximum amount of failures allowed per account, per block. (#82)
- Added "subjective-account-decay-time-minutes" option to the Producer Plugin. It sets the amount of time it takes to restore full subjective CPU to an account. (#90)
Account max failures: During block production, accounts are permitted a set number of failures before their additional transactions are dropped for a given block. This previously hard-coded limit of 3 is now configurable. Also, disable-subjective-account-billing accounts are no longer subjected to this limit.
Decay time: Users are prevented from abuse of transactions by tracking an account's subjective CPU budget. The budget is returned to an account over a period of time known as subjective account decay. This previously hard-coded decay of 24 hours is now configurable.
New configuration args for nodeos:
subjective-account-max-failures(defaults to 3)- "Sets the maximum amount of failures that are allowed for an account per block"
subjective-account-decay-time-minutes(defaults to 1440 (24 hours))- "Sets the time to return full subjective CPU for accounts"
New user-defined fields in GELF appender for Graylog
PRs
- Extend GELF appender to support user-defined fields. (eosnetworkfoundation/mandel-fc#24)
- Remove miniz in favor of boost iostreams zlib filter. (eosnetworkfoundation/mandel-fc#25)
- Logstash fails to decompress best compression but succeeds with default. (eosnetworkfoundation/mandel-fc#29)
- Update to most recent version of the fc library. (#305)
- Update fc (#330)
The GELF appender now supports arbitrary fields and accompanying values in the logging.json configuration file, with some restrictions. Per the GELF specification, user-defined field names must begin with an underscore and contain only letters, numbers, underscores, dashes, and dots. The regular expression against which field names are checked is: ^_[\w\.\-]*$. Beyond the format check, there is also a list of reserved field names which are reserved by the specification or used by nodeos. The list of reserved field names is:
- _id
- _timestamp_ns
- _log_id
- _line
- _file
- _method_name
- _thread_name
- _task_name
There is no enforced limit on the length of the field name nor the accompanying value. However, by default, Graylog servers are configured to drop UDP GELF log messages which exceed 128 fragments. The GELF appender limits its payload size to 512 bytes, so field names and values with a combined length of somewhat less than 65536 bytes may result in lost log messages. The GELF protocol allows a maximum of 256 fragments, so a combined length exceeding 131072 bytes will always result in lost log messages. There is also no enforced limit regarding the number of user-defined fields beyond those limits described above.
The Graylog server automatically elides the leading underscore in user-defined fields when displaying them in selectors and in the interface.
New --terminate-at-block option in nodeos
Nodeos can be configured to exit once it receives or replays the specified block number, allowing unattended progression to a desired state and enabling easy automation of pre-determined snapshots.
New configuration arg for nodeos:
--terminate-at-block(defaults to 0, meaning disabled)- "terminate after reaching this block number (if set to a non-zero number)"
This option is only accepted on the command line.
Building, compatibility, and upgrading
New build procedure
The shell scripts previously recommended for building the software have been removed in favor of a build process entirely driven by CMake. Those wishing to build from source are now responsible for installing the necessary dependencies. The list of dependencies and the recommended build procedure are in the README.md file. Instructions are also included for efficiently running the tests.
Ubuntu 18.04, 20.04, and 22.04 are the only build platforms that are supported. Other distributions, compilers, and platforms are known to work. Your mileage may vary.
Snapshot compatibility
This release introduces a new snapshot format. It can still load older snapshot versions. Snapshot versions and compatibility is as follows:
- v6 is the snapshot format introduced in this release (3.1). It is only compatible with nodeos version 3.1.
- v5 is a snapshot format from the unsupported EOSIO 2.1 release. Because v5 snapshots can be generated by unsupported software that may have incompatible protocol features activated, it may not generally be possible to load a v5 snapshot into a version 3.1 release of nodeos. However, if the v5 snapshot is of the state of a blockchain that has not activated any protocol features introduced in EOSIO 2.1, then the snapshot can be loaded in nodeos version 3.1.
- v4 is a snapshot format generated by nodeos version 2.0. It is compatible with nodeos version 3.1.
Network compatibility
Network compatibity means it can accept blocks and transactions over the p2p connection between nodes and will respond to requests for blocks.
This release is network compatible with nodeos version 2.0.
This release may also be network compatible with EOSIO 2.1 assuming the blockchain has not activated any protocol features specific to EOSIO 2.1.
state_history_plugin (SHiP) compatibility
This release is compatible with SHiP logs generated by nodeos version 2.0, but is NOT compatibile with SHiP logs that were written to by EOSIO 2.1.
To accommodate 3.1's new features, changes to the state history ABI were required. Consumers of state history from a 3.1 nodeos must be prepared to handle the following changes.
A new action_trace_v1 and chain_config_v1 will be sent instead of the previous _v0 versions. Remember that your client must be prepared to receive either the v0 or v1 variation since entries in your state history log prior to upgrading to 3.1 will continue to be sent to your client as v0 versions.
These new versions are listed here for convenience but the authoritative definition is the ABI sent over state history's WebSocket upon connection.

State file compatibility
This release is not compatible with the state files generated by earlier release. Please use a compatible snapshot file generated from an earlier version of nodeos.
Block log compatibility
This release is compatible with block logs generated by nodeos version 2.0.
This release is NOT compatible with block logs generated by EOSIO 2.1.
Upgrading from prior releases
Generate a snapshot of the state from an earlier version of nodeos (e.g. 2.0). See snapshot compatibiltiy section for other snapshot formats that can be used.
Remove the state file used by the node you are upgrading. If using EOSIO 2.1, you will also need to remove the SHiP and blocks logs. But SHiP and block logs can remain if upgrading from nodeos version 2.0.
Start nodeos with the snapshot. Afterwards, you can start and stop nodeos as usual.
Deprecations, removals, and dropped support
Deprecations
ABI conversion APIs deprecated
The APIs /v1/chain/abi_bin_to_json and /v1/chain/abi_json_to_bin have been deprecated as of this release and will be fully disabled or removed in a future release.
Removals
Build scripts removed
As mentioned earlier, the build scripts were removed. See README.md for instructions to build.
history_plugin removed
The history_plugin was deprecated as part of the v1.2.0 release and is fully removed as of this release.
Nodes which were being started with --plugin eosio::history_plugin will need to be migrated to --plugin eosio::trace_api_plugin or --plugin eosio::state_history_plugin.
mongo_db_plugin removed
The mongo_db_plugin was deprecated as part of the v1.8.0 release and is fully removed as of this release.
Reversible block database removed
A chainbase database is no longer used to store the active set of reversible blocks during nodeos operation. The reversible blocks continue to still be stored in the fork databasae on shutdown.
Note: Any existing configuration for the reversible block Chainbase database should be removed from the config.ini file and any scripts.
reversible-blocks-db-size-mb, reversible-blocks-db-guard-size-mb, fix-reversible-blocks, import-reversible-blocks, and export-reversible-blocks
Dropped support
Ubuntu 16.04, Centos, and macOS
As mentioned earlier, the only officially supported platforms are Ubuntu 18.04, 20.04 and 22.04. All others have been removed from binary package support and/or code level changes.
Developers using cleos, nodeos, etc. should look at DUNE which supports Windows 10 and 11, macOS, and any Linux that supports Docker.
