How to completely synchronize the data of two nodes

Mon, 24 Feb 2020 07:13:50 +0000

Hi team

My boss wants me to use multichain to build a private blockchain. Currently, a node has been opened in the background. Boss hopes to open a new node to share the pressure of the background work, such as one node for queries and another for transaction. Boss also hopes that any new data enters the background, the new node can get new data without input / output wallet operation, just like Bitcoin, one person adds data in one block, and the other person's data will also be added automatically

Permissionless Private Blockchain

Thu, 24 Jan 2019 02:49:31 +0000

I want to experiment a voting like scenario where i have about 1 to 2 lacs of addresses which will perform almost similar number of voting transactions. I am using POW and anyone-can-mine=true (for security and transparency). Of course only the voters which have addresses can send transaction. My question is what would I call this type of blockchain? Is it a permissioned private blockchain(as only register voters having addresses can participate in the process of sending transaction) OR is it a permissionless private blockchain where all the addresses can take part in mining(as anyone-can-mine=true)

How to achieve priavte transaction?

Sun, 11 Nov 2018 05:14:26 +0000

we want blockchain to keep track of transactions between company a, b, c and net out the balance. The exact transaction will be invisible to the company that is not part of the transaction.

For this I have 3 addresses on a node using getnewaddresses. But how do I make the transaction private between any two company.

What would be the best solution for this problem. Also, is making 3 addreses using getnewaddress the best approach?

Can we create a private multichain with proof of stake capability??

Managing public / private IPs for peering

Mon, 24 Apr 2017 10:35:20 +0000

Just a question, but if I have multiple multichain nodes that all reside within a reastricted network, and then attach a peer coming in via an external IP that only has access to one designated multichain node, then as far as available peers go, my new external node will try and connect to other peers that are not reachable from the network zone it's in.

Is there a way to manage what nodes are available as peers and additionally is there a way to configure public endpoints on a peer to peer basis that could be used for peering once it's determined the private IPs are not reachable....

Hope this makes sense, but looking at a potential deployment scenario which will have a mix of nodes some being public and others private and how to manage the comms between those clusters?

Cheers

How to conect my wordpress site to multichain blockchain that I am running?

Mon, 23 Jan 2017 08:56:39 +0000

Hi,

I am a beginner with Multichain. I would like to know how I can connect my wordpress site to the blockchain so that users of the website can send/receive transactions, as well as view the data streams and the blockchain. Thanks for the help.

Suggested method to blindly generate a private key that only a recipient can access

Wed, 23 Nov 2016 18:44:21 +0000

Looking for thoughts on how a user in a Multichain blockchain env might generate a private/public key address pair for the purpose of sending "value" to a recipient but only recipient would be able to decrypt priv key and sender would never be exposed to priv key, only public key. This is for an experiment so I don't need to discuss the obvious norms of why this may be nonsensical. Just curious of how a blind priv key could be generated as close as possible to zero trust / zero knowledge.

thanks,

Private key format

Fri, 05 Feb 2016 19:12:47 +0000

Hi, I'm trying to use my wallet private key in my application. I got a Base58 string as the response of the dumpprivkey command which should be in the Wallet Import Format specified by bitcoin documentation. However the length of the dumped private key is wrong (41 bytes instead of the valid 32 or 33 depending of the compression) and also if I try to make a checksum validation it fails (verifying the last 4 checksum bytes against the double hash of the private key bytes without the last 4 bytes of checksum).

Can you please explain the dumped private key format you use in multichain? Thanks a lot

Private ledger

Sat, 08 Aug 2015 12:59:16 +0000

I'm looking to use MultiChain for a permissioned ledger.

The most important aspect is that it is private, and gatekeepers can control who has access to the network.

Can you accomplish this with multichain?
