Understanding the events of Metamask and Json-RPC
As a virtual Ethereum user, however, Metamask allows a more perfect experience using alternative protocols.
The problem: Standard Ethereum with http
In the standard Ethereum API, the Chson Remote Call (JSON-RPC) is used to interact with the network, but is designed for complex complex connections such as Websockets. Http connection.
The Solution: Metamask and Websocket
Metamask provides a way to connect its local Ethereum node to blockchain using its API. Instead of trusting the Ethereum network.
** Why WS4JS?
WS4JS is a protocol that allows your web application or desktop app to the Ethereum network without a full knot. This eliminates
Metamask Websocket Connection
When this method was designed specifically to deal with bidirectional communication without requiring a complete knot.
When using WS4JS, Metamask provides a perfect experience to sign up for JSON-RPC events on the local Ethereum node, even if you are not using an official ganache instance or other note.
Conclusion
In summary, the metamask WebSocket-based approach allows users to connect their local Ethereum node to blockchain without transporting the default JSON-RPC API. This allows one more direct
