Fault tolerance

In the LO blockchain with 3f+1 (also applicable to 3f+2 or 3f+3), it has the fault tolerance performance of f nodes.
When the number of error nodes is less than or equal to f, the error node does not affect the confirmation of the transaction by the honest nodes of both parties across the chain.
Easy can keep accounts normally.
When the number of error nodes is greater than f and less than 2f+1, honest nodes cannot confirm transactions, and cross-chain transactions cannot be accounted for.
When the number of error nodes is greater than 2f+1, the error nodes may cooperate with each other and cause forks of the ledger, which can cause
The ledger data of both parties in a cross-chain transaction is inconsistent, and local ledger data can also be manipulated.
When the number of error nodes is greater than 2f+1, the error nodes may cooperate with each other and cause a fork in the ledger, which can cause inconsistencies in the ledger data of the two parties in the cross-chain transaction, and can also manipulate the local ledger data.
