This release upgrades the network inline with the Arweave 2.6 specification. While the specification details the major upgrades to the system, some of the highlights include:

  • Significantly lessened energy consumption during the mining process.
  • Oracle-free real-time detection of storage costs.
  • Increased capabilities to detect network capacity.

Please read the spec and mining guide for full details of these features

Transition and Implementation Details

The fork activates at height 1132210, approximately 2023-03-06 14:00 UTC. You will need to make sure you have upgraded your miner before this time to connect to the network.

The release comes with the prebuilt binaries for the Linux x86_64 platforms. arweave-2.6.0.0.linux-x86_64.tar.gz works on Ubuntu 21+ and CentOS 8. To run on Ubuntu 18 or 20, grab arweave-2.6.0.0.ubuntu18-x86_64.tar.gz or arweave-2.6.0.0.ubuntu20-x86_64.tar.gz . CentOS 7 is not supported.

If you want to run the miner from the existing Git folder, upgrade Erlang to version 24 and execute the following command:

git fetch --all --tags && git checkout -f N.2.6.0

See the updated mining guide for further instructions.

The new protocol comes with the new mechanism for determining upload fees and mining rewards. The new upload fee computation mechanism kicks in in 75 days after the fork activation and begins a gradual transition to the new pricing mechanism taking 12 months. Fiat price stabilization will be disabled during these 3 months until the transition begins due to high uncertainty about the network difficulty at the time. An additional hard fork adjusting the benchmark rate during this interim period is likely.

This release also adds mechanisms for potential situations in which the endowment value reaches extreme values. In the case that the endowment consumes almost all of the tokens in the system (<1mAR left outside the endowment), all tokens will automatically re-denominate by 3 orders of magnitude. This allows the tokens to continue to be usefully subdivided, despite the deflation of its supply. In the event that the endowment runs too low (signalling that the core parameter of a Kryder+ rate expectation of 0.5% is too optimistic), the network would halve the expected Kryder+ rate. This halving would repeat until a Kryder+ value is found that leads to the anticipated long-term deflation, while storage for old data continues to be honoured.

This release also includes a delay in the release of block rewards for miners by approximately thirty days (30 * 24 * 30 blocks). This mechanism is designed to incentivize miners to be aligned with the network for atleast the medium-term. The delay will start at the moment that the hard fork activates.

Complete weave replicas are required for maximizing the mining performance. Nevertheless, miners with small datasets can pool together by using a shared mining address.
