Ethereum node performance: Remote JSON RPC Edition
As a creator of Ethereum, you are probably familiar with a reliable and fast blockchain connection. However, I had a tedious problem with Remote -Json -RPC calls in one of my Ethereum nodes.
After I have been checked whether my knot actually operates the standard -bitcoind team ($ bitcoind -server -url http: // localhost: 8545) and worked through the standard, I found that the attempt to make a remote -json -RPC call to make with a library like ETHH. RPC or ETH.JS does not provide any results. Despite many attempts, I was not able to successfully send and access data about the Ethereum network.

To understand what is going on, we immerse yourself in details on how Ethereum nodes communicate with each other via the JSON RPC interface. If you start the knot with Bitcoind, an RPC server will be created in the 8545 port. The RPC customer such as ETH-RPC or ETH.JS establishes a connection to this server and sends data inquiries.
However, I noticed that some nodes reported on the problems of sending JSON objects about the Remote-Json-RPC interface. In particular, the problem is how Ethereum nodes deal with the consistency of values for JSON signs.
Solution
To solve this problem, I recommend extending your node configuration to switch on the strict JSON Consistency mode. Here are actions:
- Update Bitcoind team : Execute this command to update the RPC server associations:
Bash
$ Bitcoind -Server -Url http: // localhost: 8545 -jsonrpc -Stritt True
In this way, the JSON series can be strict and not allow unexpected data.
- Search for settings such as Jsonrpcversion or RPCURLs that can cause problems.
- Check the JSON RPC interface
: Make sure that the RPC customer library is compatible with the updated node configuration. For example, if you use ETH-RPC, update your code to use new settings.
Tips and precautions
- When updating the node configuration, make sure that all connections are successfully set up before trying to distance Json -RPC calls.
- If you have changed the rules of your network interface or firewall, you may need to configure your knot again.
- Remember that the strict JSON -SERIALICALITIONALITION regime can increase the use of memory and the slower connection speed.
Diploma
Finally, based on one of my Ethereum nodes of the JSON -RPC, I was found in the design of the JSON -RPC of the JSON -RPC because he deals with the serialization of the JSON object. By updating the Bitcoind team and ensuring the correct configuration of the JSON-RPC interface of the junction, you should be able to solve this problem and successfully carry out the JSON RPC calls with your desired library.
