PKC

為了讓群組分享激勵較為簡單例如贊助一杯咖啡，這時需要有個容易說明的換算單位，故採用普朗克咖啡 ( Planck Coffee )為換算單位，利用普朗克常數來計算波卡生態圈內代幣近似一杯普通咖啡的換算單位，簡稱普咖也就是PKC。

一杯普咖 = 1 PKC = 6,626,070,150 Planck = 0.662607015 DOT (可以想像約一杯咖啡價)

中元流動性普渡

去年本來要燒 Grin 結果太隱密很難燒換燒比特幣，今年波卡上線加上以太坊流動性挖礦風潮，趕流行徵求流動性提供者 Liquidity Provider (LP)，不需合約，直接先燒 0.5 DOT 到 11111111111111111111111111111Gzr8zVsW 地址後保證 200% 返還 1 DOT，名額有限只有五名，欲燒從速，但須等台北時間中元子時過後才開始算，注意單一地址只能燒一次。話說不管是金爐合約還是金爐跑環RUNTIME現在都還沒辦法上波卡主鏈，燒完 DOT 沒辦法自動燒出 LP token 來換個素果之類的。

// 2020年中元在國曆9月2日

一開始買來的插上去會點紅燈代表可以燒入，如果燒入完成狀態插入不會有紅燈亮，後續瀏覽器登入要求插入後會閃兩邊的燈。

info: Please insert the dongle and switch it to DFU mode by keeping the button pressed while inserting..

要再次點紅燈裡面有提到按住一個按鈕，注意不是明顯確認那個按鈕，而是下方有個方向不同的 reset 按鈕需要按住才能點紅燈。只有閃紅燈狀態可以燒入，如果出現 Permission denied: /dev/ttyACM0 權限問題就必須再執行一次 chmod a+rw /dev/ttyACM0。

github 的容器庫有兩種版本，可以無登入公開拉取的容器庫需推到 ghcr.io 

$ docker tag foo ghcr.io/dltdojo/substrate:2.0.0-rc6-1
$ docker push ghcr.io/dltdojo/substrate:2.0.0-rc6-1

外接需要 Set up Secure WebSocket for Remote Connections · Polkadot Wiki，只是要設定 nginx 會佔去機器的 443 port。

支援 Ethereum 的公鏈專案，Avalanche 架構將以太坊支援直接放在 C-Chains 上是直接出廠配備，另外波卡的 Ink! 一直改版未穩定，可直接使用 Ethereum 的 frontier 也是，而 Cosmos ethermint 只出到 0.1.0 版本。

dev chain sntpl-2.0.0-rc6-1 (DD0J1)

目前建立平行鏈 實做多資產的方式採用整合 pallet-generic-asset 方式，修改的部份 dev testnet dd0j1 with pallet-generic-assets · dltdojo/tcpdug@18ba9d5 請參考。要注意的是目前整個 substrate 的狀態即使到 rc6 還是不固定，如果版本不對，修改支援 pallet-generic-asset 的地方也必須因應改變，等到版本出來會在製作一版。

另一個修改的是 Substrate_ | Chain Specification 加上測試鏈的名稱與原生幣的單位 DD0J。

測試採用 Polkadot/Substrate Portal 來進行，除了瀏覽器不須安裝其他程式，於 Extrinsic submission 執行修改狀態之交易，另外用 Chain state 讀取狀態。
