Secure blockchain (BC)-based tokens are issued and linked to payment cards and/or devices of customers. Custom conditions associated with the tokens are stored in smart contracts on a BC. The tokens are stored in a cloud-based key vault and/or in the BC. Validation of a token for access a smart contract on the BC can only be made by a financial institution (FI) to the key vault. Real-time information for a transaction device, for transaction information, and/or for the customer is provided as input data to the smart contract for evaluation of the conditions. After the token is authenticated by the key vault, the real-time information is gathered and passed to the corresponding smart contract on the BC for evaluation. The FI receives transaction authorization or transaction denial based on the smart contract's evaluation of the conditions.

A method of transferring access to a digital asset is disclosed. The method comprises receiving a first blockchain transaction (4) from a first participant (6) by each of a plurality of second participants (8), (10). The first participant (6) has a first private key of a first private-public key pair of a cryptography system, and each participant (6), (8), (10) has a respective first share of a second private key of a second private-public key pair of the cryptography system, and the first blockchain transaction is signed with the first private key. Signature of the first blockchain transaction with the first private key is verified by each second participant (8), (10). A respective first share is applied to the first blockchain transaction to generate a respective second share of a second blockchain transaction signed with the second private key. Signature with the second private key is possible by means of a first threshold number of second shares and is inaccessible to less than the first threshold number of second shares. The first threshold number of second shares is combined from the first participant (6) and a plurality of the second participants (8), (10) generate the signature.

The invention relates to distributed ledge technologies such as consensus-based blockchains. methods for causing an injection of a serialized previous transaction into a locking script are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script. The first script, as a result of being executed, causes the node to at least obtain a first set of field values corresponding to the first transaction and obtain a second set of field values corresponding to a particular transaction. A second transaction is obtained, with the second transaction having been validated and including a second script. The second script, as a result of being executed, causes the node to at least obtain the first set of field values and the second set of field values of the particular transaction supplied as a result of execution of the first script, extract a transaction identifier from the first set of field values, and determine, based at least in part on the second set of field values, that the particular transaction corresponds to the transaction identifier. The first transaction is validated by executing the first script and the second script.

The invention relates to a method and a system for multidimensional Blockchain mining. The method makes use of a purposely delay of the time frame of the block mining in order to use the information in the block at hand as a relay to route in specific targeted node elements. The delay, which is performed on the block mining, targets the reshaping (editing) process in the blockchain implemented in this solution. By delaying the mining, the number of blocks that is otherwise needed to be edited is limited. Additionally, a chain is obtained that is more solid with regards to its incident information contents. The technical advantage of this action is depicted in the search operations performed over the optimized chain once it is edited. The above changes result in lower usage of server resources giving the opportunity to handle more events with the same number of resources.

Example data processing methods are apparatus are described. In one example method, a system includes a plurality of data management apparatuses, and each data management apparatus corresponds to one blockchain node in a blockchain network. The method includes receiving, by a target data management apparatus in the plurality of data management apparatuses, a transaction request from a blockchain client, where the transaction request includes identifiers of transaction participants. The target data management apparatus performs input/output (I/O), in the blockchain network based on the transaction request, on a transaction information ciphertext. The transaction information ciphertext is obtained by encrypting a transaction information plaintext by using a key that is invisible to a participant other than the transaction participant. The target data management apparatus then returns a transaction result to the blockchain client.

A computer system operates an off-chain electronic game that includes in-game assets stored off of a blockchain. The computer system detects an occurrence of a progression event related to a particular in-game asset associated with a particular player. In response to the occurrence, the computer system increases an upgrade capacity of the particular in-game asset. The upgrade capacity controls a maximum number of attribute upgrades that can be applied to the particular in-game asset at a time. The computer system then permits or prevents application of attribute upgrades to the particular in-game asset based on the upgrade capacity. The computer system further permits or prevents application of attribute upgrades based on whether the attribute upgrades are being applied to other off-chain electronic games. An interoperability API is used to determine whether a given attribute upgrade is being used in another game.
