An example operation may include one or more of receiving, by a blockchain node of a permissioned blockchain network, a request to transfer an asset from an asset provider to an asset requester, determining the request is valid, and in response validating one or more of an asset requester and an asset provider associated with the request, determining a risk exposure associated with the request is acceptable and generating a blockchain transaction to a public blockchain network to transfer the asset.

Database configuration for asset transfers

An example operation may include one or more of identifying a transaction from a blockchain node to be committed to a blockchain, determining a current amount of block space reserved by other blockchain nodes of the blockchain from a schedule, determining whether there is enough block space available for the transaction, and creating a block space reservation for the transaction.

Transaction scheduling for block space on a blockchain

An example operation may include one or more of identifying a blockchain transaction requiring commitment processing for commitment to a blockchain, determining the blockchain transaction is delayed, responsive to identifying the blockchain transaction is delayed, creating a transaction acceleration smart contract defining an incentive for performing the commitment processing of the blockchain transaction, and storing the transaction acceleration smart contract blockchain in a different blockchain.

Decentralized out-of-band accelerated blockchain transaction processing

An example operation may include one or more of receiving blockchain transactions, sorting an order of the blockchain transactions, simulating committance processing of the plurality of blockchain transactions to identify mining costs associated with each of the plurality of blockchain transactions, and applying one or more heuristic procedures to select one or more of the plurality of blockchain transactions which maximize a result associated with a next blockchain block.

Block creation based on transaction cost and size

An example operation may include one or more of initializing a smart contract (SC) and appending it to a blockchain, registering each of a plurality of participants as a party to the SC, receiving from at least some of the participants an encrypted confidential input commitment, appending the encrypted input commitments to the blockchain, decrypting the encrypted input commitments, executing by the SC at least one business rule using the decrypted input commitments to obtain a business rule result, and identifying a prevailing participant based at least in part on the business rule result.

Ensuring information fairness and input privacy using a blockchain in a competitive scenario governed by a smart contract

An example operation may include one or more of receiving transaction parameters for a blockchain transaction into a transaction wallet interface of a transaction wallet of a sender, the transaction parameters comprising a transaction amount and an intended recipient address. The example operation may include generating a blockchain transaction that specifies the transaction amount and a single recipient address selected from the intended recipient address and a mining pool address of a mining pool, and providing the generated blockchain transaction to the mining pool.

Privacy preserving transactions with probabilistic transaction fees

An example operation may include one or more of identifying a transaction from a blockchain node to be committed to a blockchain, determining available channels for assignment, assigning a channel to the blockchain node, and transmitting the transaction to the blockchain on the assigned channel.

Transaction reservation for block space on a blockchain

An example operation may include one or more of receiving cryptocurrency information of a cryptocurrency mined via a blockchain, determining a volatility of the cryptocurrency based on the received cryptocurrency information, in response to the determined volatility being greater than a predetermined threshold, stopping inclusion of transaction data within data blocks for storage on the blockchain, and generating one or more transaction-free data blocks, and storing the one or more transaction-free data blocks within a hash-linked chain of transaction data blocks previously stored on the blockchain.
