Coinbase 推广 cbBTC，基础区块链的包装比特币替代品

来自加密货币交易所和 Base 创始人 Jesse Pollack 的推文表明，cbBTC 可以在第 2 层区块链上运行。

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.

加密货币交易所 Coinbase (COIN) 似乎正在构建 BitGo 包装比特币 (WBTC) 的替代方案，在其自己的第 2 层区块链 Base 上运行，为用户提供一种访问网络上市值最大的加密货币的方式。

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

这一猜测始于美国时间周二晚些时候 Coinbase 发布的神秘推文，其中包括“cbBTC”和“即将推出”等措辞。

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.

随后，Base 的运营者 Jesse Pollak 发布了一条推文，概述了该团队计划如何在网络上建立“大规模比特币经济”。

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.

包装加密代币是一种使其可以在最初设计的协议之外的协议上使用的方法，从而为目标生态系统增加更多的流动性。每一个被包装的比特币都代表着被保管的原始比特币之一。当交易者想要将打包的代币兑换成比特币时，打包的版本会被“烧毁”，或者从链中删除，而原始版本会被释放。

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 宣布这一消息之际，wBTC 仍笼罩着阴云。本月早些时候，BitGo 表示正在与 BiT Global 成立一家合资企业，BiT Global 是一家在香港注册的托管平台，波场生态系统和波场创始人孙宇晨拥有部分股权。该公司表示，该合资企业将继续使用相同的 BitGo 多重签名技术和深度冷存储。

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.

由于该产品没有技术变化，而且有关基础储备的所有数据仍然可以在链上验证，因此该公告引起的反应基本上是冷淡的。然而，DAI 稳定币发行者 MakerDAO 的论坛上的一些讨论表达了负面反应。 MakerDAO 的一项执行提案将于下个月开放，要求代币持有者停止 wBTC 借贷并将 wBTC 债务限额削减至 0 DAI 以降低风险。

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 的链上数据显示 wBTC 的供应量没有变化，这表明交易者并没有试图集体退出该协议。

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 上的一篇帖子中表示，在合资企业之外，“WBTC 不会发生任何变化”，他不控制该协议的私钥，也不能移动任何 BTC 储备。

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

“我个人参与 WBTC 完全是战略性的，”他写道。
