Because the result that block common recognition is performed dependent on contract, each node must be reached to the uniformity of the result of contract
Common recognition, therefore, the speed of the execution speed of contract directly affects block subsequent operation, causes block to generate the delay of time.
(2) speed that contract is performed has a strong impact on the contract execution concurrency that block chain can be supported：
In the case where the frequency that block chain is generated is generally approximately fixed, within the same period, a contract is performed
Speed, will directly influence under the execution of same other contracts of block, extreme case, the contract of a malice may cause system
Other contracts can not be handled, cause the concurrency for handling contract to substantially reduce.
(3) fault-tolerant ability in contract implementation procedure is limited：
Because by the way of synchronously performing, processing when contract is performed for various error situations needs to consider comprehensively,
And the quick processing of the operation to various time-sensitives is realized, than making corresponding place if desired for the timeout case to various operations
Reason.
Some existing solutions, such as ether mill, by the way of gas, the estimation of operand is carried out to each contract,
And the total operand for controlling current block to support using the total gas amounts of a system, to ensure being timely completed for common recognition.But
