暗号通貨勉強会：BitGoのWBTCカストディ問題など
下記について話したPodcastです。 * BitGoがWBTC発行のためのBitcoinのマルチシグウォレットの鍵のホルダーを3分割。従来は３つのキーの全てをBitGoが管理していたが、そのうち二つを香港ベースのBiT Globalに渡すとしていた。しかしコミュニティから新しいエンティティのBiT GlobalがWBTCを動かせるようになる２つのキーを管理することへの反発がおき、最終的にBitGo SingaporeとBiT Global、BitGoがそれぞれ１つずつキーを管理することになった。BiT Globalは悪名高いTron創業者のJustin Sunも出資しており、これでWBTCのリスクが高まったと考えられ、MakerDAOはWBTCを外す提案をしている * Coinbaseが「cbBTC」「coming soon」というツイートをしたことでCoinbaseがラップドBTCを発行するのではないかと噂される。現在BitGoのWBTCは154,000、約$9B相当がEthereum上で流通している * Swellがリキッドステーキング用のswBTCをローンチ
