Release Notes

The BitShares Core software has been updated to the 4.0.0 Protocol Release. The Core software is used to build the validation nodes that perform consensus of all transactions on the BitShares blockchain. This release includes additions, improvements, and changes to the consensus protocol.

The scheduled protocol upgrade time is Thursday, July 30, 2020 13:55:00 UTC (2020-07-30T13:55:00Z).

Documentation for users may be be found at How BitShares Works.

Documentation for BitShares developers may be found at the BitShares Developer Portal.

Who Should Upgrade?

All operators must upgrade to handle the protocol upgrade and to benefit from performance improvements.

Operators of API nodes will be able to configure custom limitations on their API nodes as described in the API section.

Upgrade Process

Precautions

  • All validation nodes must complete their upgrade prior to Protocol Activation: Thursday, July 30, 2020 13:55:00 UTC
  • A blockchain replay will automatically be performed after the validation node software is restarted. This typically takes a few hours on a modern CPU.

Upgrading from Any Version

Delayed Node

The witness_node program can be configured to serve the features that were previously provided by the delayed_node program. Therefore the delayed_node program is no longer supported. Instructions for configuring a witness node to act as delayed node can be found in the Wiki.

Elastic Search Plugin

The default values for the Elastic Search Plugin have been changed. These changes are summarized under Elastic Search Plugin.

Custom Operations Plugin

A new custom_operations plugin is added in this release which is enabled by default for new nodes. The plugin stores account catalogs of key=>value data using custom operations. The feature is expected to be utilized by several client applications including the reference UI and the BTS++ mobile App in the near future. Existing public API nodes should enable it.

API Helper Indexes Plugin

The api_helper_indexes plugin is now required for serving several existing critical APIs. Public API nodes should enable it. Please check the API section for more info.

Upgrading from 3.2.0

Operators of API nodes need to edit their configuration file per the instructions in the 3.3.0 Release Notes API section.

Upgrading from before 3.2.0

Please check the 3.2.0 Release Notes for more information if you are upgrading from a version prior to 3.2.0.

How to Upgrade from Source Code

Note: the minimum build requirements have changed starting from the 3.3.0 Feature Release:

  • The code base requires a compiler that supports the C++ 14 standard (previously C++ 11).
  • The minimum supported boost version is 1.58 (previously 1.57).
  • The minimum supported CMake version is 3.2 (previously 3.1).

Obtain the Source Code

The source code may be obtained by checking out the 4.0.0 tag. Download the source at:

Build the Binaries

The binaries may be built by using your pre-existing process, or by following the standard instructions that can be found in the wiki:

Deploy the Binaries

Your standard process for deploying the node software may be used. No additional requirements or precautions will be required to deploy the new release.

How to Upgrade with Docker

The latest Docker image may be found at BitShares Core Docker page and updated with

docker pull bitshares/bitshares-core

Binaries for download

Binaries of the command line interface (CLI) wallet and the node software are pre-built and available for download.

Note: These binary builds are reproducible and were signed using Gitian. Please check the README if you want to verify and/or contribute.

Is the custom_operations_plugin meant to be active on public API nodes? If so we should mention it.
