## 開發進度
- jserv / afcidk
- [hashchain](https://github.com/DLTcollab/hashchain): be a limited source of authentication
- Base -> Hash~0~ = H(Base) -> Hash~1~ = H(Hash~0~) -> ... -> Hash~N~ = H(Hash~N-1~)
- given the last hash in the chain, Hash~N~, it is very difficult to determine any of the previous hashes, or the base. However, given the last hash, it is trivial to verify whether another hash is part of the chain.
- [evm-lite](https://github.com/mosaicnetworks/evm-lite): A lean Ethereum node with interchangeable consensus
- Contract Proxy for IOTA
- how to reuse spent address(es)?
- yillkid
- Resize the node8 storage from 1TB to 2TB [#217](https://github.com/DLTcollab/general/issues/217)
- marktwtn
- entangled: trit/tryte 轉換使用 SIMD SSE4.2 優化 [#1443](https://github.com/iotaledger/entangled/pull/1443) (review 中)
- 感謝 howjmay 協助 bazel 除錯 (需使用 bazel 最新版本)
- dcurl: 把 logging 函式改成與 entangled 相同的命名 [#180](https://github.com/DLTcollab/dcurl/issues/180) (完成)
- 實作不同，dcurl 是自己的實作，entangled 使用 logger 專案
- dcurl 只有 log_debug() 跟 log_info()，未來要跟 entangled 一樣有多重等級的 logging 函式
- dcurl: 釋出 [v0.5.0](https://github.com/DLTcollab/dcurl/releases/tag/v0.5.0)
- dcurl: 修正 CppCheck 偵測到的錯誤 [#173](https://github.com/DLTcollab/dcurl/issues/173) (進行中)
- IRI: 平行 attachToTangle() API 與 FPGA 的效益 [#162](https://github.com/DLTcollab/general/issues/162#issuecomment-536841078)
- YingHan
- Architecture of in/out path with scylla [link](https://hackmd.io/_cmh3WfhSSyAk-ivMCf7yg?both)
- Implement program to import historical transaciont and listen newly confirmed transaction [#323](https://github.com/DLTcollab/tangle-accelerator/pull/323)
- Test on Node8

- ender503
- Infra: PoW Remote Worker Log Management [#204](https://github.com/DLTcollab/general/issues/204)
- 使用 thetangle 來取得過往的交易紀錄
- **需要 yillkid 提供 token 的 HTTP header 格式**。
- ex: x-api-key: fdf4afc5-179a-4ad1-8606-ab4fdd746fa3
- Infra: Monitoring the systemd service status [#219](https://github.com/DLTcollab/general/issues/219)
- Infra: Setup Scylla Cluster with Multi Data Centers (DC) on Node1 [#218](https://github.com/DLTcollab/general/issues/218)
- Node1 的 ScyllaDB 先使用 localhost 來取代 node1.puyuma.org 的設定
