Coinbase 推廣 cbBTC，基礎區塊鏈的包裝比特幣替代品

來自加密貨幣交易所和 Base 創始人 Jesse Pollack 的推文表明，cbBTC 可以在第 2 層區塊鏈上運行。

Crypto exchange Coinbase (COIN) is seemingly building an alternative to BitGo's wrapped bitcoin (WBTC) to operate on Base, its own layer-2 blockchain, giving users a way of accessing the largest cryptocurrency by market capitalization on the network.

加密貨幣交易所Coinbase (COIN) 似乎正在構建BitGo 包裝比特幣(WBTC) 的替代方案，在其自己的第2 層區塊鏈Base 上運行，為用戶提供一種訪問網絡上市值最大的加密貨幣的方式。

The speculation began with cryptic tweets from Coinbase late Tuesday U.S. time, which included the wording: "cbBTC" and "Coming soon."

這項猜測始於美國時間週二晚些時候 Coinbase 發布的神秘推文，其中包括「cbBTC」和「即將推出」等措辭。

These were followed by a tweet from Jesse Pollak, who runs Base, outlining how the team is planning to build a "massive bitcoin economy" on the network.

隨後，Base 的營運者 Jesse Pollak 發布了一條推文，概述了該團隊計劃如何在網路上建立「大規模比特幣經濟」。

Wrapping a crypto token is a way of making it available on protocols other than the one it was originally designed for, adding more liquidity to the target ecosystem. Each wrapped bitcoin represents one of the original, which is held in custody. When a trader wants to redeem the wrapped token for bitcoin, the wrapped version is "burnt," or deleted from the chain, and the original is released.

包裝加密代幣是一種使其可以在最初設計的協議之外的協議上使用的方法，從而為目標生態系統增加更多的流動性。每一個被包裝的比特幣都代表著被保管的原始比特幣之一。當交易者想要將打包的代幣兌換成比特幣時，打包的版本會被“燒毀”，或者從鏈中刪除，而原始版本會被釋放。

Coinbase's announcement comes as a cloud hangs over wBTC. Earlier this month, BitGo said it was setting up a joint venture with BiT Global, a Hong Kong-registered custody platform that is partly owned by the Tron ecosystem and Tron founder Justin Sun. The venture will continue to use the same BitGo multisignature technology and deep cold storage, it said.

Coinbase 宣布這項消息之際，wBTC 仍籠罩著陰雲。本月早些時候，BitGo 表示正在與 BiT Global 成立一家合資企業，BiT Global 是一家在香港註冊的託管平台，波場生態系統和波場創始人孫宇晨擁有部分股權。該公司表示，該合資企業將繼續使用相同的 BitGo 多重簽名技術和深度冷儲存。

The announcement drew a largely muted response as there is no technical change to the product and all data about underlying reserves continues to be verifiable on-chain. However, some chatter on the forums of DAI stablecoin issuer MakerDAO expressed a negative reaction. A MakerDAO executive proposal for token holders to stop wBTC borrowing and cut wBTC debt limits to 0 DAI to reduce risk is open for the next month.

由於該產品沒有技術變化，而且有關基礎儲備的所有數據仍然可以在鏈上驗證，因此該公告引起的反應基本上是冷淡的。然而，DAI 穩定幣發行者 MakerDAO 的論壇上的一些討論表達了負面反應。 MakerDAO 的一項執行提案將於下個月開放，要求代幣持有者停止 wBTC 借貸並將 wBTC 債務限額削減至 0 DAI 以降低風險。

On-chain data from Dune shows there has been no change in supply for wBTC, suggesting traders aren't trying to exit the protocol en-masse.

Dune 的鏈上數據顯示 wBTC 的供應量沒有變化，這表明交易者並沒有試圖集體退出該協議。

In a post on X, Sun said that there will be "no changes to WBTC" outside of the joint venture and he does not control the protocol's private keys and can't move any of the BTC reserves.

Sun 在 X 上的一篇貼文中表示，在合資企業之外，“WBTC 不會發生任何變化”，他不控制該協議的私鑰，也不能移動任何 BTC 儲備。

"My personal involvement in WBTC is entirely strategic," he wrote.

「我個人參與 WBTC 完全是戰略性的，」他寫道。
