A creating and trading system for tokenized open-end fund and a method thereof are disclosed. In the creating and trading system, a fund-end host deploys a smart contract corresponding to an open-end fund in a blockchain network, a performance fee is calculated and a token value is adjusted based on a ROI of an open-end fund, so that when a purchase request of a buyer's host is received, a token is generated based on the token value and the purchase request, and transmitted to a wallet address of the buyer's host, and a register of shareholders in the smart contract is updated; when a transfer request is received, a subscription function and a redemption function of the smart contract are executed to simulate a transfer transaction. Therefore, the fund-end host can centralize the process to avoid a transfer agent, to improve convenience, transparency and liquidity of fund transaction.

Block header hashes of a blockchain are used as tokens for time stamps. Since the blockchain is ubiquitous with the block header hashes randomly generated and are practically immutable, the time stamps using the block header hashes are secure. A time stamping system uses a block header hash as a time stamp can be used to time stamp digitalized representation of a physical object. The time stamped digitalized representation of a physical object can be used as proof of current ownership of the physical object if the time stamp is adequately recent.

Certain aspects of the present disclosure provide techniques for reliable cryptocurrency rebroadcasting. According to certain embodiments, after an initial transaction broadcast disclosed systems listen to a blockchain to determine if the transaction was included in the blockchain. If, after a short time period, the transaction is not confirmed, a transaction database record for the transaction is locked to prevent inadvertent rebroadcast. While the record is locked, the transaction format and replay information are verified, and depending on the blockchain, is updated. For blockchains having a transaction fee, the system reviews recent transactions to determine appropriate fees and if needed, updates the transaction fee accompanying the transaction. Once the replay information is verified/updated, and the transaction fee is sized appropriately, the database record is unlocked and the transaction is rebroadcasted.
