Inquiry remote Bitcoin node: RPC and Ethereum
Since you are familiar with the request for Bitcoin Blockchain, you may be wondering how to achieve the same features, use a remote control, such as RPC (remote procedure call). In this article, we will investigate how to use RPC nodes, such as a public knot to be a request for Ethereum Blockchain.
** Why a query for RPC knots?
RPC nodes are ideal for asking “blockchain” because they are:
- are publicly available : Anyone can access and ask the RPC knot using their own public address.
2.
- Allow asynchronous inquiries : RPC knots allow you to send inquiries asynchronously, which is useful for large -scale programs.
Sent on GetblockCount RPC Node
You will need to use a “curly” command or similar tool to ask the Blockchain to ask the Blockchain using a public knot. Here’s how:
- Get RPC address : Find the public address of your RPC knot you want. You can usually find this information in a knot documentation or by searching online.
2.
`Bash
#!/Bin/bash
rpc_address = "your_rpc_address"
Get_blockCount = $ (Curl -S -x Get "https: // $ rpc_address/api/block/0")
Echo '$ get_blockcount'
Change your_rpc_address with your real RPC node public address.
3.
- Check output : Scenario will see the number of block first block block number.
Additional options
To improve the inquiry process, consider adding additional parameters to your Curl team:
-dosbose: Increases output verbism, making it easier to analyze.
- -Silent
: Disables output that can help solve combination problems.
- -Timeout = 5000
: sets the request time (in this case 5 seconds).
- -Max Size = 1024m
: Limits the amount of answer (in this case 1 MB).
Example Use cases
Some of the queries you can send by using a RPC knot such as a public knot is:
- GetblockCount
- Gettransactionid
- GettransACTION
- Getblock
- Gettransactionbyhash`
When asking Ethereum Blockchain, remember that some queries may require additional parameters or headlines to ensure proper functionality.
Conclusion
In this article, you have learned to ask the remote Bitcoin knot, such as the RPC knot, using your machine software. You can be the same technique as to achieve Ethereum Blockchain by sending GetBlockCount inquiries to public knots. By performing several experiments and configurations, you will be able to send a variety of questions and gain valuable insights into Ethereum Blockchain.
