The distribution ratio of the last six cross-chain integrated clearing smart contracts is 1000/8000=1/8. At this time, n×1/8=5000×1/8=625 points, i.e., the first six cross-chain point clearing smart contracts can be allocated to obtain 625 points.
Referring to fig. 3, the method for agreeing on the universal conversion price includes:
step C01) each of a plurality of cross-chain integral clearing intelligent contracts 10 generates a pass exchange price, generates a confusion code randomly, extracts hash values of the confusion code and the exchange price and sends the hash values to a voting initiator;

the method for determining initial point allocation by voting comprises the following steps:
after the settlement account period is finished, the cross-chain point clearing intelligent contracts exchange the points of the corresponding blockchain users into corresponding number of pass certificates, and the points are transferred into the point accounts;
counting the integral use quantity by the plurality of intelligent contracts for cross-chain integral clearing, wherein the intelligent contract for cross-chain integral clearing with the largest integral use quantity is used as a voting initiator, and the voting initiator generates an initial integral allocation scheme and sends out votes;
and if the intelligent contract for the cross-chain integral clearance exceeding the preset proportion agrees with the initial integral allocation scheme, the initial integral allocation scheme passes, and initial integral allocation is carried out according to the initial integral allocation scheme.
7. The digital asset cross-chain transaction method based on cross-trusted coalition chain of claim 6, wherein:
the method for the voting sponsor to generate the initial point allocation scheme comprises the following steps:
dividing the total amount of the integral into three parts according to a proportion, wherein the first part is directly distributed to a voting initiator, the second part generates an allocation scheme by the voting initiator, the integral amount of the third part is recorded as N, the voting initiator receives the application amount reported by other intelligent contracts for clearing the integral across the chain, calculates the sum of the application amounts, calculates the proportion of the application amount to the sum of the application amounts reported by each intelligent contract for clearing the integral across the chain, the proportion is used as the allocation proportion of the corresponding intelligent contract for clearing the integral across the chain, the product of the integral amount N of the third part and the allocation proportion is used as the integral allocation amount distributed to the corresponding intelligent contract for clearing the integral across the chain, and the allocation sum of the three parts is used as the initial integral allocation scheme.
8. The digital asset cross-chain transaction method based on cross-trusted coalition chain of claim 6, wherein:
the method for agreeing to pass the evidence to exchange the price comprises the following steps:
each of the plurality of cross-chain integral clearing intelligent contracts generates a pass exchange price, generates a confusion code randomly, extracts hash values of the confusion code and the exchange price and sends the hash values to a voting initiator;
after receiving the hash values sent by all the cross-chain integral clearing intelligent contracts, the voting sponsor informs all the cross-chain integral clearing intelligent contracts of public license exchange price and confusion codes;
calculating the products of initial points and bids of the intelligent contracts through a plurality of cross-chain integral clearing contracts, freezing the corresponding number of pass certificates, and thawing the pass certificates in a settlement period;
the voting sponsor extracts the hash value of the through certificate exchange price and the confusion code disclosed by the cross-chain integral clearing intelligent contract, and compares the hash value with the received hash value for verification;
if the verification is inconsistent, judging that the current agreed pass exchange price is illegal, and re-executing the agreed notification exchange price method, otherwise, calculating the weighted average of all pass exchange prices by taking initial points as weights, and taking the weighted average as the agreed pass exchange price.
9. The digital asset cross-chain transaction method based on cross-trusted coalition chains of claim 8, wherein: the voting initiator calculates the allowed bid interval;
the allowable bidding interval is k1 times to k2 times of the last accounting period through-certificate exchange price, k1 and k2 are preset coefficients, and the bid which is lower than k1 times of the last accounting period through-certificate exchange price is regarded as k1 times of the last accounting period through-certificate exchange price, and the bid which is higher than k2 times of the last accounting period through-certificate exchange price is regarded as k2 times of the last accounting period through-certificate exchange price.
10. A digital asset cross-chain transaction system based on a cross-trusted coalition chain for performing the digital asset cross-chain transaction method based on a cross-trusted coalition chain as claimed in any one of claims 1 to 4, 7 to 9, characterized by:
