MultiChain is a fork of Bitcoin Core.
MultiChain is a permissioned consortium blockchain protocol.
MultiChain achieves consensus by validating blocks in a round-robin scheme with a
All nodes with the addresses with the
mine permission take a turn in validating blocks in the network.
The way the
mine nodes take turns in validating blocks is determined by the network's
mining-diversity parameter can be set to any value between
minenode in the network must take a turn in block validation per round. This is the strictest setting.
0— not every
minenode must take a turn in block validation per round; any
minenode can take turns in block validation in a random fashion. This is the loosest setting.
The round-robin scheme is the following:
- Determine the number of nodes with the
minepermission in the network.
- Multiply the number of
minenodes by the
mining-diversityvalue to get the value spacing.
- Check if the
minenode validating the current block validated a spacing-1 block. If the
minenode validated a spacing-1 block, render the block invalid.
mining-diversity parameter is
0.3 and cannot be changed once the chain is initialized.
Round-robin example with 10
mine nodes with
mining-diversity set to
- 10 nodes permitted to validate blocks.
- 10×0.3=3. spacing is 3. spacing-1 is 2.
minenode in the network can validate every third block and cannot validate two blocks in a row.
A MultiChain network is deployed with the following service node:
