Uptime

Changed minimum uptime requirement to receive a staking reward from 60% to 80%.

Networking

Added 3 new network messages: AppRequest, AppResponse and AppGossip. These messages allow instances of a blockchain to send arbitrary data to each other as defined by their VM. Previously, instances of a blockchain could only communicate with one another by sending consensus messages (Put, PushQuery, etc.). See snow/engine/common/engine.go.
Upon receipt of a Pong message, disconnect from the sender if their version is incompatible.
Prepended method named in common.Sender with Send for clarity (e.g. Put --> SendPut).

Config Flags

Removed

conn-meter-reset-duration
conn-meter-max-conns

Added

network-compression-enabled

Prometheus Metrics

Many Prometheus metrics were renamed, and many histograms were replaced with 2 gauges. See here for updated Grafana Dashboards.

This release also adds helper methods to the utils/metric package.

RocksDB

RocksDB is no longer built by default when running the build script, and it is not included in publicly released binaries. To build AvalancheGo with RocksDB, run export ROCKSDBALLOWED=1 in your terminal and then scripts/build.sh. You must do this before you can use --db-type=rocksdb.

The RocksDB database now places/looks for its files in a subdirectory rocksdb. Note that if you previously ran with RocksDB, you'll need to move the existing files.

Message Compression

Nodes now compress some P2P messages. If a peer is version >= v1.4.11, Put, Push Query, Peer List and Multiput messages sent to the peer are compressed using gzip before being sent over the network. This reduces AvalancheGo's bandwidth usage.

Inbound Connection Throttling Refactored inbound connection rate-limiting and enable it by default.

General Improvements

Refactored and improved performance of iteration over a database served by gRPC to a plugin.
On Linux, clean up the C-Chain if AvalancheGo dies ungracefully

If the previously installed node version is v1.4.5 then this node use the existing database and does not need to perform a database migration.

This patch:

Removes invalid transaction issuance into P-chain mempool that caused high sustained DB writes.
Ignored non-database files and folders in the database directory. This should specifically fix errors reported on macOS with .DS_Store files.
Fixed the build-dir flag to be able to be specified via CLI without causing the preupgrade node to error.
Removed the plugin-dir flag that is no longer supported with the node-manager daemon. Typically not specifying the flag leads to the correct behavior. However, for complex installations the build-dir flag may be required.
Enforced gossiping messages only to connections that have finished the peer handshake.
Reduced memory allocations during consensus traversals and bootstrapping.

v1.4.5 (View on GitHub)

Apricot Phase 2 - Patch 5 - DB Upgrade

This upgrade is more involved than the typical version update.

caution

This update is backwards compatible. It is optional, but encouraged. The patch includes significant performance improvements and numerous other updates.

VM Improvements:

Fully redesigned the platformvm's state management.
- Removed the usage of versiondbs being passed through blocks to pass state references that can be modified and read without re-parsing objects.
- Implemented a base state manager to properly cache and mange writes to the underlying database.
- Implemented CoW validator sets to enable caching multiple validator sets in memory.
- Indexed chains by Subnet to avoid touching unused state objects.
- Indexed validators by nodeID to avoid unnecessary iterations while accepting addDelegator and addSubnetValidator transactions.
- Reduced the number of key-value pairs dedicated to managing validator sets on disk and validator uptimes.
Added staking reward look-ups to the platformvm's API to support indexing of rewards.
Refactored validator uptime metering to simplify testing.
Added block and transaction type metrics to the platformvm.
Added API call metrics to the avm and the platformvm.
Updated the avm's state management to use prefixdbs, record caching metrics, and share additional code with the platformvm.
Simplified UTXO management and indexing in the avm and platformvm.
Restructured address parsing and management to be fully shared across compatible VM instances.
Restructured shared memory of the primary Subnet to be fully shared across VM instances.
Added a chain state implementation to support seamless caching over existing VM implementations and to simplify the implementation of new VMs.
Integrated the new chain state manager into the rpcchainvm, which also adds various metrics.
Added upgradeBytes and configBytes to the standard VM interface to better support future network upgrades.
Added getAtomicTx and getAtomicTxStatus endpoints to the evm API.
Simplified evm block production to be synchronously performed with the consensus engine.
Added an atomic transaction mempool to re-introduce orphaned atomic transactions.
Fixed bug in the evm client to properly set the sourceChain in getAtomicUTXOs.
Integrated the new chain state manager into the evm to better optimize block management.

Bootstrapping Improvements:

Removed re-traversals during bootstrapping. This significantly improves the performance of the node during restarts of the bootstrapping process.
Fixed an ungraceful node shutdown when attempting to exit the node while executing bootstrapped containers.
Fixed duplicated IPC container broadcasts during bootstrapping.
Standardized the bootstrapping jobs queue to write to state using prefixdbs rather than implementing custom prefixing.
Added additional bootstrapping caching and cache metrics.

Database Migration Additions:

Added a daemon process manager to seamlessly migrate to the updated database format.
Refactored version handling to track database semantic versions.
Implemented a database manager to track and operate over different database versions.
Implemented a keystore migration that automatically copies users from the v1.0.0 database to the v1.4.5 database.
Implemented a validator uptime migration from the v1.0.0 database to the v1.4.5 database.

Node Improvements:

Updating config parsing to always expand environment variables.
Refactored the node config to allow specifying TLS certificates in memory without touching disk.
Added better support for meaningful exit codes.
Displayed listening address of the http and staking servers to aid in supporting non-specific port mappings.
Implemented a versionable database to be able to toggle between a pass through database and a versioned database.
Optimized ID Set pre-allocations and reduced the memory usage of the structs.
Enforced stricter linting rules.

Modified command line arguments:

For the following arguments "default" was previously treated as a keyword. Now, "default" will attempt to be treated as the intended value of the flag. To retain the default behavior, the flag should not be specified.

config-file
coreth-config
plugin-dir
staking-tls-key-file
staking-tls-cert-file
bootstrap-ips
bootstrap-ids
ipcs-path
db-dir

For the following arguments "" was previously treated as a keyword. Now, "" will attempt to be treated as the intended value of the flag. To retain the default behavior, the flag should not be specified.

ipcs-chain-ids
log-dir
log-display-level

It is no longer required that the bootstrap-ips and bootstrap-ids are paired. This means it is now valid to specify a different number of bootstrap-ips than bootstrap-ids. The bootstrap-ips are used to initially connect to the network and the bootstrap-ids are used as the beacons in bootstrapping.

Added command line arguments:

fetch-only
build-dir

Removed command line arguments:

xput-server-port
xput-server-enabled

Fixed benched message handling that could cause a node to be unable to progress during bootstrapping. This was typically experienced when the node would fail to transition to normal execution as it was finishing bootstrapping.
Fixed a non-deterministic bug in the C-Chain codebase that could cause nodes that receive a lot of transaction broadcast requests to temporarily stop producing blocks until they process a block produced by another node.
Restricted the number of version messages to be sent to a peer to one.
Removed legacy handshake messages that were deprecated in Apricot Phase 2.
Marked nodes that have been benched as being offline for uptime calculations.
Updated the validator set to be more performant during validator set changes.

Apricot Phase 0 - Upgrade 1

danger

Please note that this patch is not backwards compatible with previous releases. This upgrade fixes performance issues related to interchange transfers between X, C, and P chains. We urge everyone in the community to upgrade as soon as possible in order to ensure that their nodes are not affected. Also, note that nodes may take several extra minutes to connect after the upgrade and the process should be allowed to complete uninterrupted.

The primary components to this upgrade include:

Fixed atomic import validation on C-Chain
Added rule exception logic to allow atomic bonus blocks
Added fail-fast logic into Shared Memory if duplicated deletes are issued
Fixed issue where polls could stall in snowman because of a failure to clear requests

v1.0.4 (View on GitHub)

danger

This update is optional but encouraged. The patch includes quality of life improvements and various performance enhancements. Note that this update requires the CLI parameters to be specified with -- rather than allowing for either - or --. For example, -public-ip=127.0.0.1 is no longer allowed and must be specified as --public-ip=127.0.0.1. Otherwise, this update is backwards compatible.

• Added Subnet whitelisting to allow a node owner to choose which Subnets to validate.

• Added config file parsing for node settings.
• Added more options for specifying a node's IP address and added getNodeIP to the info *endpoint.
• Added a TxID to the result of get.Validators in the platformvm.
• Updated Coreth version.
• Cleaned up the snowball trie implementation and added additional tests to align with mutation tests.
• Implemented and optimized continuous time averages for tracking CPU and network latency.
• Significantly optimized memory allocations in various locations.
• Increased the signature verification cache size.
• Reduced DB reads during vertex management.

• Added an optional argument includeReason to platform.getTxStatus.
If not provided, or if false, the output from getTxStatus is the same as before.

For example:
{
    "jsonrpc": "2.0",
    "result": "Dropped",
    "id": 1
}

If includeReason is true, the output from getTxStatus has a new format. It's an object that looks like this:

{
    "jsonrpc": "2.0",
    "result": {
        "status":"[Status]",
        "reason":"[Reason tx was dropped, if applicable]"
    },
    "id": 1
}

In this new format, reason will not be present unless the status is Dropped.
Anything that depends on platform.getTxStatus should switch to using the includeReason argument and use the new response format. After a few releases, we'll only support the new response format.
