Installation and usage of the platform

General platform configuration: mining

The blockchain mining parameters are in the miner section of the node configuration file:

miner {
  enable = yes
  quorum = 2
  interval-after-last-block-then-generation-is-allowed = 10d
  micro-block-interval = 5s
  min-micro-block-age = 3s
  max-transactions-in-micro-block = 500
  minimal-block-generation-offset = 200ms
}

  • enable - activation of the mining option. Enable - yes, disable - no.

  • quorum - required number of node miners to create a block. The 0 value will allow to generate blocks offline and is used only for test purposes in networks with one node. When specifying this value, take into account that your own miner node does not sum up with the value of this parameter, i.e. if you specify quorum = 2, then you need at least 3 miner nodes for mining.

  • interval-after-last-block-then-generation-is-allowed - enable block generation only if the last block is not older the given period of time (in days).

  • micro-block-interval - an interval between microblocks (in seconds).

  • min-micro-block-age - a minimal age of the microblock (in seconds).

  • max-transactions-in-micro-block - a maximum number of transactions in the microblock.

  • minimal-block-generation-offset - a minimal time interval between blocks (in milliseconds).

The mining settings depend on the planned size of transactions on your network.

Also, blockchain mining is closely related to the chosen consensus algorithm. The following parameters of the miner section must be taken into account when configuring the consensus parameters:

  • micro-block-interval - an interval between microblocks (in seconds).

  • min-micro-block-age - minimum age of microblock. The value is specified in seconds and must not exceed the value of micro-block-interval.

  • minimal-block-generation-offset - a minimal time interval between blocks (in milliseconds).

The values of microblock creation parameters must not exceed or otherwise conflict with the values of average-block-delay for PoS and round-duration for PoA and CFT. The number of microblocks in a block is not limited, but depends on the size of the transactions included in the microblock.
