A computer-implemented method of partitioning a blockchain network into shards is disclosed. The method comprises the steps of identifying a transaction id of a blockchain transaction and allocating the transaction to a shard based on the transaction id.

Embodiments relate to a method for transferring at least one source token of a source set of tokens from a source blockchain of a source blockchain network to a target blockchain of a target blockchain network. A method comprises providing an approval of the transfer, initiating an issuing transaction of at least one target token in the target blockchain of the target blockchain network, and verifying an annihilation of the at least one source token in the source blockchain of the source blockchain network.

A network of computing nodes and a method of operating the computing nodes effectuate, in real-time, an international, money transfer from the bank account of a first person (the payer) in a first country to the bank account of a second person (the beneficiary) in a second, different, country.

A method for protecting a login process of a user to a service provider against brute force attacks is provided. A financial value is transferred from the user to a token provider for a temporary login token. A login attempt is performed by the user on the service provider, wherein the login attempt requires user specific login data and the temporary login token. If the login on the service provider was successful within a predefined number of login attempts, the financial value is transferred back to the user.

Systems and methods for expediting math-based currency (MBC) transactions are described. A financial institution facilitates the expedited MBC transactions. The expedited MBC transactions are achieved by guaranteeing merchants that a pending MBC transaction between the merchant and a customer will be verified by the MBC verification nodes. A provided guarantee can be collected on by the merchant in the event that a guaranteed MBC transaction is not verified by the MBC verification nodes.

The application provides a secure financial settlement method and system of blockchain, which is applied to the blockchain data system, the system comprises settlement node 1, settlement node 2, and data center. The technical solution relates to the application has the advantage of high security.

A method for generating and providing a two-dimensional code is provided. The two-dimensional code encodes data for loading a client side of a decentralized application in a web browser of a client device. The two-dimensional code also encodes a private key of a blockchain account that has been funded with a predetermined amount of crypto-currency. The method can also include creating the blockchain account. The method can further include funding the blockchain account with the predetermined amount of crypto-currency and refreshing one or more of the two-dimensional code and the blockchain account. Related systems, computer-readable mediums, and articles are also described.

An improved blockchain implementation that uses proof-of-transfer to overcome the technical deficiencies of proof of work and proof-of-stake implementations is described herein. For example, the proof-of-transfer process may include elements of a single-leader election sortition, but modified to cause base chain cryptocurrency committed for the purposes of the sortition to be transferred to a burn address or at least one reward address.

The method comprises transferring a digital asset from a first user to a second user. The method comprises authenticating the first user as the owner of the digital asset by inspecting a transaction database. The method comprises transferring the digital asset from the first user to the second user by updating the transaction database so as to identify the second user as the owner of the digital asset; and by providing a graphic asset associated with the digital asset to a user electronic device of the second user. The transfer of the digital asset may be validated using a distributed ledger such as a blockchain. The method may be performed by a system 800 comprising user electronic devices 200A, 200B, 200C, and a transaction database 801. The system comprises a user electronic device 200 comprising a communicator 201, and a processor 207 communicatively coupled to the communicator 201.
