[英]Why do you need an browser extension like MetaMask to make transactions on Ethereum?
是什么阻止Web应用程序直接在区块链上访问和进行交易?
Technically, you don't need MetaMask. 从技术上讲,您不需要MetaMask。 You do need access to a node on the blockchain.
您确实需要访问区块链上的节点。 That can be achieved by running a fully synced or light node on a client, or by having your web app talk to a server connected to a node.
这可以通过在客户端上运行完全同步的节点或轻量节点,或者通过使Web应用程序与连接到该节点的服务器对话来实现。 MetaMask is one of many ways.
MetaMask是多种方式之一。 It just happens to be the most popular (right now).
它恰好是最受欢迎的(现在)。
