Accumulate developers are announcing Testnet 8 Millennium – Mainnet Release Candidate 2. Named after the Millennium bridge located in London, England, Accumulate’s Testnet 8.0 includes a variety of updates.

Additionally, from this point onwards (until further notice), there will be two Testnets to make sure that third-party applications can remain stable. In addition, the DevNet will remain. The mobile application is compatible with the Beta RC1 version of the Testnet.   

  1. Testnet Beta RC1 is Testnet 7.0   
  2. Testnet Beta RC2 is Testnet 8.0   
  3. DevNet is DevNet   

The mobile application will point to the Testnet Beta RC1 is Testnet 7.0  endpoint, which will be compatible with the Testnet Beta RC1 branch (Develop Branch – tag cli-v1.0.0-rc1.2) in the CLI and Testnet Beta RC1 in the Explorer ( To use new features in Accumulate, connect to the Testnet Beta (8.0) Branch (Develop Branch – Tag cli-v1.0.0-rc2) in the CLI and use the Testnet Beta RC2 option in the Explorer ( To interact with the Devnet use the Develop branch in the CLI and the Devnet option in the explorer (   

To switch from one branch to another in the CLI type git branch and the branch you would like to connect to. Make sure to do a git pull and go build to get the latest updates in the CLI.

  • Allow new Factom data entries – a user can choose to write data in the same manner as a Factom data entry 
  • Variable fee schedule update – for multi-operation commands in Accumulate, such as sending ACME tokens to multiple outputs, each additional output will be charged a fee. Please see the change in the fee schedule below:
