Week 32 August 2025 §

nim libs §

• Complete the ABI encoder / decoder PR (https://github.com/status-im/nim-web3/pull/216)
  • Fix offsets encoding issue
  • Use nim-fastream api advance to avoid loading the whole buffer in memory for dynamic data
  • Apply PR’s feedback (comments, handling int overflow decoding…)
  • Replace the old encode / decode functions by the new decoder in nim-web3
  • Test in eth1 (https://github.com/status-im/nimbus-eth1/pull/3554)
  • Testing in eth2 and nwaku (in progress)

Altruistic mode §

Status desktop requirements §

Status desktop requirements FURPs PR has been created: https://github.com/status-im/status-desktop/pull/18483)

New altruistic design ideas §

• Eric — replication network alternative
• Eric — replication network alternative — over simplified assumptions
• Balazs — additions to the altruistic musings

Specs §

Kicked off specs effort for existing modules. Template: https://hackmd.io/@codex-storage/rkbytlbOxg Kanban of components to spec: https://github.com/orgs/codex-storage/projects/6/views/1 Due 15 August Specs will be contained in https://github.com/codex-storage/codex-docs-obsidian

Offsite §

Have more or less decided on mid-November for the offsite, to come after a prototype is delivered, as there is not a lot of other convenient times due to holidays and other availability considerations (eg paternity leave). Location will be in Europe to keep costs down. Initial idea is Canary Islands but could move to more central Europe to drop costs further.

Roadmap §

We are working towards a roadmap that replaces bittorrent in status-go with a prototype of the new Codex.
