Abstract

The invention discloses a settlement method on a block chain. The method is characterized in that some public key addresses are authorized with the right to issue digital currencies or digital assets through a voting system on the block chain, and association can be achieved through CA certificates with relevant authorities; a user can convert cash into the digital currencies on the block chain in equivalent value, or entrust assets to an issuer to obtain the digital assets on the block chain in equivalent value; as long as both parties reach a transaction agreement, even without an intermediary, the digital currencies or the digital assets can be simultaneously transferred to a public key address of the other party after private key signing by one party in person on the block chain, so that the digital currencies and the digital assets can be settled without arrears.

Description

Settlement method on block chain
Technical field
The present invention relates to Internet technical field, particularly the clearing of block chain, enciphered digital currency, enciphered digital assets.
Background technology
Existing bit coin block chain technology, complete decentration manages, it does not have the regulator at center, and the asset association being difficult in the franc with national distribution or reality is got up.
Existing exchange vanilla transaction fund is required for after closing the same day just clear, interbank clearance neither be completely real-time, and all data bases still can be distorted by hacker, and server security requirement of shelter is high especially, although there being many people to check system, but also cannot prevent altered data in partnership.
Customer transaction relates to signing a contract in affixing one's seal and is required for substantial amounts of human cost, but cannot be entirely prevented from contractual fraud, and risk is also all implied in unsecured transaction.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this technology introduce can undertake acceptance liability publisher, distribution block chain digital cash and block chain digital asset, facilitate the settlement of transactions on block chain.
The invention provides the block chain scheme for settling accounts, it is necessary to the user of settlement of transactions, as long as in advance fund and assets being exchanged into the digital cash on block chain and digital asset can be concluded the business voluntarily, it is not necessary to intermediary.
The technical solution adopted in the present invention is: the block chain scheme for settling accounts, and is had the right of distribution digital cash or digital asset by some PKI address of the ballot system mandate on block chain, it is possible to associated by the CA certificate of associated rights. User can exchange the block chain digital cash of equivalence in cash, user can obtain assets trustship the block chain voucher of the digital asset of equivalence to publisher, as long as owing to both sides conclude the transaction agreement, can when without intermediary, on block chain, digital cash or digital asset are transferred to the other side's PKI address after my private key signature simultaneously, close digital cash and digital asset, neither owe mutually.
Block chain digital cash can be that various countries issue currency, such as RMB, dollar, Euro, pound, yen etc., it is also possible to is virtual coin such as bit coin, and issuer undertakes and last cashes responsibility. Block chain digital asset can be stock, credits, futures contract, staple commodities, raw material, commodity, the service that can mark the price, and issuer undertakes and last cashes responsibility. Issuer can be bank, exchange, capital company, fund, enterprise or or individual etc. have the focal pointe of capacity of acceptance.
Between various digital cash can settlement of transactions, can also settlement of transactions between various digital assets.
Being voted by block chain or authoring system can authorize some PKIs to be the CA certificate center managing user, the identity of user can be verified in these centers, provides the CA certificate of different trading privilege, such as trading limit according to its credit level. Trustship through the encrypted private key of user's safety problem or the remedial after private key is lost as password can be given for change, accept private key and report the loss the service freezing PKI address, user can also have super authority in the center of authorizing, at checking user identity, after one section of public notification period, change client public key address, the digital cash on old PKI address or digital asset are transferred to new address.
Voted by block chain or authoring system can authorize the mechanisms such as some references that the transaction record of user is evaluated, the complaint of acceptable user or arbitration, continuously user is carried out credit rating, white list, blacklist etc. can be set up, short-term can also freeze the transaction of client public key address, it has been found that irregularities can submit to law enforcement agency to enforce the law further. Credit information service obtains the accreditation of block chain by the private key signature that PKI is corresponding, and user be dealt on block chain after the evaluation of oneself can also be encrypted, and password is informed credit information service simultaneously.
Voted by block chain or authoring system can authorize some law enforcement agencies to have super authority, or only more than two right units of associating just can force to freeze, shift digital cash or the digital asset of user, can first freeze, after one section of public notification period, perform transfer instruction again.
Compared with prior art, the invention has the beneficial effects as follows and fund block chain digital cash is replaced, assets are replaced to trustship center block chain digital asset, both sides' transaction can carry out either directly through block chain, participate in without intermediary, sign papery contract and nor is it necessary that, it is not necessary to affix one's seal and check the identity of counterparty, especially those are needed repetitious transaction, it is not necessary to the block chain transaction checked the capitals and examine goods substantially increases trading efficiency.
Also introducing authentication mechanism, credit information service, law enforcement agency on block chain, the work of functional department directly completes on block chain, simplifies flow process and improves efficiency.
Accompanying drawing explanation
Fig. 1 be illustrate to conclude the business between user digital cash and digital asset realize step.
Detailed description of the invention
Step is realized below in conjunction with what accompanying drawing 1 illustrated to conclude the business between user digital cash and digital asset:
1 fund of user proceeds to 2 digital cash distribution and honours bank account a little, and 2 will squeeze into digital cash of equal value the PKI address 3 of user A.
5 assets of user proceed to the trustship center of 6, and 6 will squeeze into digital asset of equal value the PKI address 7 of user B.
User's B PKI address 7 issued by user's A PKI address 3 100 yuan after A private key signature, and 10 strands of digital assets in user's B PKI address 7 are sent to A PKI address 3 after B private key signature simultaneously.
This example demonstrates that user identity and rights management:
Being voted by block chain or authoring system can authorize some PKIs to be the CA certificate center managing user, the identity of user can be verified in these centers, provides the CA certificate of different trading privilege, such as trading limit according to its credit level. Trustship through the encrypted private key of user's safety problem or the remedial after private key is lost as password can be given for change, accept private key and report the loss the service freezing PKI address, user can also have super authority in the center of authorizing, at checking user identity, after one section of public notification period, change client public key address, the digital cash on old PKI address or digital asset are transferred to new address.
This example demonstrates that and how to supervise user:
Voted by block chain or the grading of transaction record that authoring system can authorize some credit information service's PKIs to be user, and accept complaint or the arbitration of user, continuously user is carried out credit rating, white list, blacklist etc. can be set up, short-term can also freeze the transaction of PKI address, it has been found that irregularities can submit to law enforcement agency to enforce the law further.
