Ethereum: Does bitcoind accept batch RPC calls?
Ethereum: accepts Bitcoin Batch RPC calls?
In this article we will examine whether the official API of Ethereum with the name “Openzenpelin” “RPC” (Restful Protocol-Calls) of “RPC” (Restful Protocol-Calls), supports RPC calls.
Overview
As a developer who builds up applications for both Ethereum and Bitcoin, it is important to understand how to interact with the APIs of every blockchain. In this article, we will examine the current state of support for attacked RPC calls between Ethereum and Bitcoin via the OpenSpelin -RPCinterface.

The documentation of Ethereum Developer describes the "RPC" API as follows:
"An RPC server is a standard HTTP-based protocol with which you can send requirements for a service that is carried out on another computer. This protocol supports two operating modes: synchronous and asynchronous."
For Bitcoin, the official API (Bitcoin Cash) was also optimized for the synchronous and asynchronous communication.
OpenSpelinsRPCinterface
The Openzenpelin library offers a high-ranking abstraction for the construction of relaxing APIs both in Ethereum and Bitcoin. With the "RPC 'interface" it enables developers to send requirements for services that are carried out on these blockchains using standard -http methods (get, post, put, delete).
Here is an example of how you can use the Python interface interface:
Python
Import JSON
Import inquiries
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'}
Payoad = json.dumps ({...})
Answer = Requests.post (f'http: // {self.host}: {self.port}/rpc ', data = payload, header = header)
Batching RPC call
With regard to batched RPC calls, the OpenSpelin -RPCinterface currently supports asynchronous communication. This means that you can send several inquiries at the same time without waiting for everyone to be completed before you continue with the following commands.
Here is an example of how you can use Batching RPC calls with the "RPCinterface" class:
Python
Import JSON
Def Pull (command, Foo):
Create an instance of RPCinterface
rpc = rpcinterface ('http: // localhost: 8545', 8545)
Define a attacked command
batch_command = {
'Method': 'My_Method',
'Params': ['arg1', 'arg2']
}
Send the Batch command to Stack (up to 10 commands)
for i in the area (0, len (batch_command ['params']), 10):
Payoad = json.dumps ({{{
** Batch_command,
'ID': Str (i)
})
Answer = rpc.execute_command (payload)
print (f'command {i+1} complete: {response.json ()} ')
Example use:
Pull ('my_method', {'arg1': 'value1'})
As you can see, this example shows how several commands are stacked in stacks (up to 10 commands) at the same time with the “RPCinterface” class.
Diploma
In summary, it can be said that the official API of Ethereum (RPC) and Openzenpelin’s” RPC` interface “support both Batching -RPC calls. You can use these Python and Bitcoin interfaces to create scalable applications that interact with both blockchains.
However, it is important to note that RPC calls specified in all scenarios are not available, e.g. B. if the network of blockchain is overloaded or when the service called is heavily loaded. To maximize the performance, it is recommended to use asynchronous communication if possible.
Future improvements
While the development of Ethereum and Bitcoin is developing, we can expect further improvements to your APIs.
