Abstract

Provided is a block chain information matching platform. A fund demand side publishes bill information onto a block chain to form a bill token, and a fund supply side obtains a corresponding settlement token of the platform through fund deposition. The fund supply side selects the bill token and then pays the settlement token to form a contractual relationship. After a bill transferred from the fund demand side is received and confirmed, the fund demand side can obtain the settlement token and withdraw real funds. On the platform, the bill token and the settlement token are matched in a smart contract by using block chain technology, and transaction operations such as listing and delisting, financial operations such as recharge and withdrawal, and confirm operations such as ECDS transfer and bill collection are all written into a block chain to ensure that each fund transaction and bill transfer are in a one-to-one correspondence, procedures for data clearing and fund settlement of a traditional matching platform are reduced, and the fund demand side can obtain funds immediately.

After the fund supplier selects the bill token, it pays the settlement token to form a contractual relationship. After receiving the bill transferred from the fund demander and confirming it, the fund demander can obtain the settlement token and can withdraw the real fund.

[0007] The capital demand side enters the basic information of the holding bill on the platform, including the bill number, the drawer, the acceptor, the due date, the coupon amount, etc. After the platform is approved, the corresponding bill token is sent to the capital demand side. In the public key address. Searching for the hash value of the entry operation, you can query the CA identity information, entry information, and ticket basic information of the fund demand side.

[0008] After the capital demander sets the discount rate, the discount fee, and the financing amount, the private key signature confirms the listing transfer ticket, and the ticket token is sent to the platform smart contract address. After the fund provider deposits the funds into the bank's bank escrow account, the platform issues the corresponding settlement token to the platform account of the fund provider. When the fund provider confirms the investment target, a corresponding amount of settlement tokens are sent to the smart contract for the matching transaction. Searching for the hash value of the listing and delisting operations, you can query the identity authentication of the participating parties, the basic information of the ticket, the discounted transaction information, and the transaction time.

[0009] The subsequent transaction confirmation between the parties to the ECDS ticket system, and the confirmation of the receipt and payment, require a private key signature, and the operation record is written into the blockchain. The search operation hash value can be used to query the information of the day, type, bill amount, etc. of the specific operation, and search for the public key address of both parties of the transaction, and can query all historical operations of the address.
