in #bitshareslast month (edited)

Release Notes

The BitShares Core software has been updated to the 5.0.0 Protocol Release. The code name of the release is "Splash". 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 Monday, September 28, 2020 17:00:00 UTC (2020-09-28T17:00:00Z).

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 node operators must upgrade to handle the protocol upgrade.

Upgrade Process

Precautions

  • All validation nodes must complete their upgrade prior to Protocol Activation
  • A blockchain replay will automatically be performed after the validation node software is restarted. This typically takes a few hours on a modern CPU.

How to Upgrade from Source Code

Note:

  • The code base requires a compiler that supports the C++ 14 standard
  • The minimum supported boost version is 1.58, the maximum is 1.69.1
  • The minimum supported CMake version is 3.2
