• 伊達雲從 8/29 1600 至 8/31 2100 停機(node2 - node6)維護

  • 臨時iota-swarm-node: http://node0.puyuma.org:8000

• proof.K

  • 利用 FPGA accelerator 的實驗

開發進度

• Synchronization is stuck again #937

• powsrv note

• proof.K

  • Base: Neighbor Node Management
  • Base: Improve CTPS and reduce confirmation time

• ender503

  • TangleID-DID register and resolver
