JWT allows for stateless authentication between you and your endpoint. Multiple Authentication Tokens - Create multiple authentication tokens for each of your deployed endpoints. This allows you to revoke any tokens that may be comprised, without needing to restart your non-compromised endpoint. To roll an individual authentication token, create an additional token and then delete the previous token.

Learn more about multiple authentication tokens in this QuickNode guide. Check if you have it by running the following: curl -h curl -h Web3.

The client sends a request to the server, and the server returns a response back to the client.

An HTTP connection is closed after the response for a given request is sent. HTTP is supported in every browser as well as almost all programming toolchains. Due to its ubiquity it has become the most widely used transport for interacting with Geth. To start a HTTP server in Geth, include the --http flag: geth --http If no other commands are provided, Geth falls back to its default behaviour of accepting connections from the local loopback interface The default listening port is The ip address and listening port can be customized using the --http.

Instead, they have to be whitelisted explicitly when Geth is started. The default whitelist allows access to the eth, net and web3 namespaces. To enable access to other APIs like account management personal and debugging debug , they must be configured using the --http.

This is achieved using the --http. A Websocket connection is maintained by client and server until it is explicitly terminated by one. Most modern browsers support Websocket which means it has good tooling. Because Websocket is bidirectional, servers can push events to clients. That makes Websocket a good choice for use-cases involving event subscription.

Another benefit of Websocket is that after the handshake procedure, the overhead of individual messages is low, making it good for sending high number of requests.
