Ethereum: Does Bitcoin Accept Group RPC Calls?

In this article, we will take a closer look at whether the official Ethereum API, called the OpenZeppelin rpc (RESTful Protocol-Calls) interface, supports group RPC calls.

Overview

As a developer building applications on both Ethereum and Bitcoin, it is important to understand how to interact with each blockchain’s API. In this article, we will take a look at the current state of support for group RPC calls between Ethereum and Bitcoin via the OpenZeppelin rpc interface.

Ethereum rpc API

The Ethereum developer documentation describes its rpc API as follows:

“An RPC server is a standard protocol based on HTTP that allows requests to be sent to a service running on another machine. This protocol supports two modes of operation: synchronous and asynchronous.”

In the case of Bitcoin, the official API (Bitcoin Cash) has also been optimized for synchronous and asynchronous communication.

OpenZeppelin rpc interface

The OpenZeppelin library provides a high-level abstraction for creating RESTful APIs on both Ethereum and Bitcoin. The rpc interface allows developers to send requests to services running on these blockchains, using standard HTTP methods (GET, POST, PUT, DELETE).

Here is an example of how you can use the OpenZeppelin rpc interface from Python:

import json
import requests
class RpcInterface:
def __init__(self, host, port):
self.host = host
self.port = port
def execute_command(self, command, foo=None):
headers = {'content-type': 'application/json'}
payload = json.dumps({...})
response = requests.post(f' data=payload, headers=headers)

Batching RPC calls

When it comes to batching RPC calls, the OpenZeppelin rpc interface currently supports asynchronous communication. This means you can send multiple requests at once without having to wait for each one to finish before moving on to the next command.

Here is an example of how you can use RPC batching with the RpcInterface class:

import json
def pull(command, foo):





Create an RpcInterface instance
rpc = RpcInterface(' 8545)

Define a batch command
batch_command = {
'method': 'my_method',
'params': ['arg1', 'arg2']
}

Send a batch command in batches (up to 10 commands)
for i in range(0, len(batch_command['params']), 10):
payload = json.dumps({
**batch_command,
'id': str(i)
})
response = rpc.execute_command(payload)
print(f'Command {i+1} complete: {response.json()}')

Usage example:
pull('my_method', {'arg1': 'value1'})

As you can see, this example shows how to send multiple commands in batches (up to 10 commands) at once using the RpcInterface class.

Conclusion

To sum up, the official Ethereum API (rpc) and OpenZeppelin’s rpc interface support batch RPC calls. You can use these interfaces from Python and Bitcoin to build scalable applications that interact with both blockchains.

However, it is important to note that group RPC calls are not available in all scenarios, for example, when the blockchain network is congested or when the service being called is under heavy load. To maximize performance, it is recommended to use asynchronous communication whenever possible.

Future Improvements

As Ethereum and Bitcoin continue to evolve, we can expect further improvements to their APIs.
