## 重要變革
* 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](https://hackmd.io/s/SJ7i1QnIX)

## 開發進度
* [Synchronization is stuck again #937](https://github.com/iotaledger/iri/issues/937)
* [powsrv note](/s/HkRiiUGw7)

* proof.K
* [Base: Neighbor Node Management](https://github.com/DLTcollab/general/issues/89)
* [Base: Improve CTPS and reduce confirmation time](https://github.com/DLTcollab/general/issues/81)
* ender503
* [TangleID-DID](https://github.com/TangleID/tangleid-did) register and resolver
* Use [TIC](https://github.com/cr0ssing/tic.api.js) to maintain the DID Document
* 目前 TIC 僅支援 Profile and Contacts
* 如果要在 TIC 支援 claims 需要調整 TIC 的專案。
* Claims 的資料格式可以參考 W3C 的 [Verifiable Claims](https://www.w3.org/TR/verifiable-claims-data-model/)
* [Claims Use Cases](https://www.w3.org/2017/05/vc-use-cases/CGFR/2017-05-01/#finance)
* [DID Auth](https://www.w3.org/TR/verifiable-claims-data-model/) 驗證使用者權限, 其中包含使用者個資和 Claims。
* [WIP] TangleID client
* BETA 版預計會提供 Android 手機使用 APK 進行安裝。
* csielee
* [meta-tangleid](https://github.com/DLTcollab/meta-tangleid) (a meta layer)
* `tangleid.bb`
* install shell scripts for tangleid
* setting `UUID` and `backend`
* `mender_%.bbappend`
* add `UUID` for identity and inventory
* [WIP] develope `tangleid-mender-state-scripts.bb`
* [TODO] write README for usage
* jkrvivian
* merged: [Initialize TCP/UDP receiver services with ports from configuration variables](https://github.com/iotaledger/entangled/pull/146)
* [entangled git hooks tutorial](https://hackmd.io/8yV5-YVbQM-2KWRZ9C11mQ?view#git-hook-installation)
* [WIP] Implement `getopt_long`
* HowJMay
* [Remove recursion in merkle tree implementation](https://github.com/iotaledger/entangled/pull/176)
* [Implement URI parser](https://github.com/iotaledger/entangled/pull/204)

* [TangleID API Reference](https://hackmd.io/vtDUuQgcSU-mzGoqq0Pftw)
* new_claim - Create a new claim for authed identity
* [get_tips(1)](https://github.com/yillkid/iota-swarm-node/blob/747e2218b3414cb70f395207a2bf7f038852e1b9/extensions/tangleid/main.py#L48)
* swarm node不向full node要tip
