Aptos以20億美元的估值籌集2億美元重啟Diem項目:金色財經報道，Aptos博客稱，在Meta公司確認關閉其加密貨幣相關資產之后，Aptos正在將Diem區塊鏈再次帶入生活。據兩位不愿透露姓名的消息人士稱，該團隊正以20億美元的估值籌集2億美元來實現這一目標。知情人士稱，Andreessen Horowitz（a16z）和其他幾家加密貨幣風險投資公司都參與了這項交易。

一位了解該項目的消息人士表示，Aptos團隊正在基于最初的Libra白皮書構建其新的第一層區塊鏈。對潛在投資者的宣傳是 “沒有Facebook的Libra\"。與Libra不同的是，該項目的重點將不是跨境支付，而是不可偽造的代幣。

據悉，Aptos由Avery Ching和Mo Shaikh創建，Ching之前在Meta的Novi加密貨幣子公司工作，被認為是Diem區塊鏈的DiemBFT共識協議的共同創造者。（Coindesk）[2022/2/24 10:13:58]
