Example 6 with ChainContainer

use of io.nuls.consensus.poc.container.ChainContainer in project nuls by nuls-io.

the class BlockProcess method checkForkChainFromMasterChain.

/**
 * When a block cannot be connected to the main chain, it is checked whether it is a branch of the main chain.
 * If it is a branch of the main chain, a bifurcation chain is generated, and then the bifurcation chain is added into the forked chain pool to be verified.
 * <p>
 * 当一个区块不能与主链相连时，检查是否是主链的分支，如果是主链的分支，则产生一条分叉链，然后把该分叉链添加进待验证的分叉链池里
 *
 * @return boolean
