How can I retrieve blockchain data via MultiChain JSON-RPC API and efficiently handle large datasets?

Fri, 12 Dec 2025 12:44:12 +0000

I am trying to access blockchain data using MultiChain’s JSON‑RPC API for development purposes. I want to retrieve blocks, transactions, and associated metadata programmatically and handle large datasets efficiently. Any guidance on best practices, pagination, or API limitations would be helpful. Example use cases include exporting transaction histories and monitoring blockchain activity in real-time.

what is "pubkey" in 'getaddresses' API and how is different than Public Key i.e. "address"?.

Creating manually conection between 2 nodes

How do I create the conection ?

Difference between admin-consensus and round-robin consensus?

Fri, 05 Apr 2019 10:57:53 +0000

Hello Team ,
I have gone through white paper where i have read about roub robin consensus and now i am trying documents of multichain , so I am just little confused in admin-consensus and round robin consensus ?
When multichain will use round robin and when it will use admin -consensus?

As per my learning when i was trying to deploy stream filter in network(3 nodes with admin permissions) so in that case 50% admin node has to agree on that transaction that's how admin-consensus comes in and round-robin consensus used for stream transaction etc .
If i am wrong please correct me.

Difference between master and 2.0-release

Thu, 04 Apr 2019 13:04:38 +0000

Hey there.
I would like to ask what's the difference between the versions in the two branches in the GitHub repository?
I can see that the `master` branch has been updated recently (unlike the `2.0-release`) and it has some things about Google's V8 engine.

I know that version 2 of Multichain was released some months ago, so I was wondering why the `2.0-release` branch hasn't been updated for a year.

Which branch should I use for personal development?

MultiNodeJS: Multichain 2.0 Wrapper for Nodejs

Tue, 26 Mar 2019 14:54:42 +0000

Due to lack of maintenance I decided to update the Node.js wrapper with the new API commands. I also wasn't a fan of the previous test suite, but I'm still building one, so be aware of that (even though I think everything should work fine).

MultiNodeJS:

Github: https://github.com/sdec-brasil/multinodejs

NPM: npm install multinodejs

What's the difference between Multichain and products like BigchainDB?

Tue, 21 Aug 2018 00:31:18 +0000

I read the following article https://www.multichain.com/blog/2016/12/spot-half-baked-blockchain/ where Gideon explain that to be a real blockchain it has to comply with six attributes. After, I read the article I believe that Bigchain DB has all those 6 attributes unless I am missing something. Can you please provide what you think separates multichain from bigchain DB? besides the fact that multichain is built over bitcoin core and bigchain db is like adding blockchain properties to big data.

Next MultiChain 2.0 preview release

Wed, 25 Apr 2018 02:22:53 +0000

When are you expecting to release the next MultiChain 2.0 alpha/beta release? I want to build a program using 2.0 but I want to wait for the next preview release in case there's API changes.

Hyperledger Fabric vs Multichain 2.0 for time-series database

Sun, 15 Apr 2018 15:48:21 +0000

Hi there,

I was wondering what is the advantage of Multichain versus Hyperledger Fabric from a time-series database point of view? From my understanding, Hyperledger Fabric maintains a series of asset transactions and writes these asset transactions out to a world view once confirmed (a traditional database for the purpose of querying). http://hyperledger-fabric.readthedocs.io/en/latest/ledger/ledger.html

What is the advantage of using Multichain with data streams for these transactions and writing the datastream items out to a traditional database? To me, the open source nature of Multichain and the fact that it is a fork of Bitcoin Core are advantages. Could you list any others?

Stopping A Node

Sun, 01 Apr 2018 12:34:28 +0000

This might seem like a dumb question but I just want to be sure. So I have two nodes connected to each other on the same server. The first node is the one that created the blockchain. If I stop it using the command:

>sudo multichain-cli [chain-name] stop

Will that automatically kill all the other nodes created afterwards that are connected to the blockchain as well? Also is it possible to stop one node without stopping the entire blockchain and the other nodes connected to it?

What is the difference between Node and a Wallet?

Tue, 13 Mar 2018 07:07:57 +0000

Is Wallet a package API inside a Node or is it a subsystem like Node on Multichain platform?

If so how node interacts with wallet to get Transactions details from a mined block?

Difference between Multichain and Cosmos(Tindermint)

Thu, 09 Nov 2017 07:45:21 +0000

Hi,

What is the difference between Multichain and Cosmos(Tindermint)? Is the working principle same? In case of Cosmos, there are multiple parallel blockchain running and they can communicate with each other via BCI. In multichain, can we do similar actions. I would like to work on multiple blockchains working in parallel and all the Blockchains are independent with each other. In this case, will it be a permissioned or permissionless blockchain.

Thanks.

Multichain vs Hyperledger vs Sia for file storage and sharing?

Sat, 09 Sep 2017 13:43:04 +0000

Which of these is better. And why is multichain better than the others?

Multichain vs Openchain

Wed, 23 Aug 2017 11:54:47 +0000

Hello Multichain Team,

I read that in open-chain, instead of forming a block of the transaction and then appending that block to blockchain, open-chain directly appends transaction to blockchain without forming the block. Effectively it is transaction chain.

So, this makes the open-chain superfast in confirmation of the transaction. But given the structure of how blockchain works, I think that it's a normal blockchain whose block contains only one transaction (I am not sure, but we have to include somewhere the hash, etc so a block must be formed)

So, My question is does really making only one transaction per block speeds up the blockchain? Is this Openchain better in performance when compared to multichain?

Is MultiChain a hybrid of Bitcoin and Ethereum?

Fri, 14 Jul 2017 03:33:38 +0000

Although I do not know much about the subject yet, could they answer the question?

what is the difference between Multichain(bitcoin-style) and Bitcoin?

Thu, 08 Jun 2017 01:50:35 +0000

Thanks for your answer which let us have a more accurate understanding of Multichain.

If we create a Mutichain Blockchain with bitcoin-style, what is significant difference between Mutichain Blockchain and Bitcoin Blockchain?

1) A new wallet (version 2)? Higher efficiency ?

2) Configurable parameters ?

Thanks in advance
