支付业巨头 Visa 发布了一项提案，允许以太坊用户们在没有任何第三方参与的情况下进行自动化的可编程支付 (automated programmable payments)。<\/strong><\/p>

根据最近一个加密货币思想领导的职位，该公司计划使用智能合约来实现这一目标，该智能合约充当用户帐户和合约帐户之间的中介，创建一个自我保管的钱包，可以在不参与的情况下进行自动的定期付款，且无需银行或其他中央实体的介入。<\/strong><\/p>

虽然此类服务已经可供银行账户的持有人和传统金融公司的用户使用，但目前尚无法透过区块链网路来获得该功能。因此，Visa 的目标是成为第一家将此类功能引入以太坊网路的公司。<\/strong><\/p>

“在区块链上，这类交易并不是那么简单，”该公司表示，并补充说它计划在以太坊第 2 层网路 StarkNet 上部署该解决方案。 Visa 央行数位货币和协议负责人 Catherine Gu 表示：<\/strong><\/p>

“如果区块链的主要用例之一是支付，那么基本要求就是区块链的功能如果不是更好的话，至少必须和今天一样好。”<\/strong><\/p><\/blockquote>

Visa 表示，他们之所以想出这一功能，是因为其 2022 年加密货币骇客马拉松挑战赛，该公司员工在 2 月份举行的一场竞赛，旨在解决 ETH 所有者如何在未来某个日期使用加密货币支付账单的问题，同时暂时离开互联网的服务。<\/strong><\/p>

截至目前，以太坊网路上有两种类型的账户：由私钥控制的外部账户（EOA）和本质上是智能合约的合约账户（CA）。<\/strong><\/p>

EOA 可以发起交易，而 CA 不能。然而，透过使用账户抽象 (AA\/ accountabtraction)，将智能合约和钱包合并到以太坊区块链上的单一类型账户的想法，可以创建一个可以代表 EOA 发起交易的智能合约。<\/strong><\/p>

AA 的一个用例是创建“可委托账户”，它允许通过使用智能合约实现支付的自动化。值得注意的是，AA 的想法可以追溯到 2015 年，最初由以太坊联合创办人 Vitalik Buterin 所提出。该提案于 2017 年正式确定为以太坊改进提案 (EIP) 86。<\/strong><\/p>

在交易所的以太坊余额处于历史的低位<\/strong><\/h2><\/span>

在最近加密货币交易所 FTX 的内爆和用户对中心化平台的信任恶化的情况下，大型或“鲸鱼式”的钱包继续从交易所撤回资产。据 Bitfinx 分析师称，2022 年是交易所持有的 BTC 和 ETH 历史上最大的跌幅。<\/strong><\/p>

据报导，全球最大的加密货币交易所币安上周一天的净提款额超过 30 亿美元。在最近的一份报告中，Bitfinix 表示：<\/strong><\/p>

“2022 年中心化交易所持有的 BTC 和 ETH 比去年同一时期的跌幅来讲为最大，均下降近 20% 11 月的百分比跌幅是 BTC 历史上第三大月度跌幅和 ETH 历史上第五大月度跌幅，均出现百分比跌幅是自 2017 年以来最大的一次。”<\/strong><\/p><\/blockquote>","protected":false},"excerpt":{"rendered":"
