To achieve the above object, the technical scheme adopted by the invention is as follows: it is a kind of without arbitrate solve typing block chain friendship
The authentic and valid method of easy data, includes the following steps
S1: resource user A requests resource R to resource provider B；
S2:B generates the unique identification currently traded with the address of A and B, current time stamp ts and a random salt
TID (Transaction ID), and TID is sent to ATID=H (addrA, addrB, ts, salt)；
Resource R is divided into several pieces R=[R1, R2 ..., RN] by S3:B；
S4:B provides resource RX to A, and before to A requesting to obtain and promising to undertake that PX:A recognizes to receiveIt and can be this pair
Take
S5: after A receives PX, verifying PX content, signs to obtain PX ' to Px with A private key, and by PX ' be sent to BPX '=
Sign(PX,KeyA)；
S6:B receives the promise PX ' that A has signed, then continue to send next resource RX+1 (jump to step 4), otherwise into
Enter next step；
S7:B is completed or is interrupted transaction, and the PX ' received for the last time is put on block chain and is verified；
S8: block chain verifying PX ' content simultaneously checks whether TID is unique, executes relevant contract according to content by rear.
Further, described in this process of exchange, how small granularity division of no matter trading is, practical Exactly-once transaction,
Expense is very low, and transaction content is undeniable.Third-party intervention is not all needed in the whole process, and can be real-time
Verifying.
Compared with prior art, the authentic and valid method tool of the transaction data that this kind solves typing block chain without arbitration
It has the advantages that::
1, the prior art obtains the data outside block chain using prophesy machine；Prophesy machine is the tissue of a centralization, phase
Than decentralization distributed network lack data can not distort attribute, data transformation is credible；In error in data, need
To determine by third party arbitration organ, and timeliness lags；In addition, needing to pay certain usage charges using prophesy machine
With.
2, the present invention solves that obtain the outer data of chain credible using prophesy machine bring data transformation, needs to arbitrate, when
Effect property lag, and the problem of higher cost.
3, the present invention provides a kind of trading scheme, both parties it is incomplete trust in the case where, for reduce loss with
The transaction granularity of very little is traded, once certain Fail Transaction, then subsequent transaction stops, and such both sides only can be at last
Secondary transaction is disputed on.When transaction granularity is sufficiently small, this loss will also be become insignificant.But exists in real trade and open
In the case where selling (service charge etc.), transaction granularity will be limited, especially in block chain, the transactional overhead of smaller particle size
It will become difficult to receive.
4, for the present invention to solve the problems, such as to propose a kind of algorithm above, core concept is that increment promises to undertake algorithm；Pass through
Algorithm of the invention, in this process of exchange, how small granularity division of no matter trading is, and practical Exactly-once transaction, expense is very
It is low, and transaction content is undeniable.Third-party intervention is not all needed in the whole process, and can be with real-time verification.
