0001 The invention relates to distributed ledge technologies such as consensus-based blockchains. Computer-implemented methods for a trustless, deterministic state machine are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction validate is received at a node in a blockchain network. The first transaction includes a first script that, as a result of being executed, causes the node to at least obtain a first set of field values of the first transaction, a second set of field values of a second transaction, and an input. The second transaction is obtained. The second transaction includes a second script that includes a set of rules and, as a result of being executed, causes the node to at least verify that the second script matches a third script embedded in the first set of field values, determine, based at least in part on the second set of field values, a current state, and determine, based at least in part on the current state, the input, and the set of rules, a next state. The first transaction is validated as a result of execution of the first script and the second script.

Disclosed are systems and techniques for activating and deactivating entities of a blockchain network. A request is received to register an entity of the blockchain network. In response to receiving the request, an ending state balance is determined for the entity, and a reference to the entity is added to an active entity data structure that maintains references to active entities of the blockchain network. After adding the reference to the active entity data structure, a determination is periodically performed of whether any active entities have insufficient state balance for continuing participation in the blockchain network, by comparing a global accumulator to respective ending state balances of entities referenced in the active entity data structure. In response to determining that a given entity has insufficient state balance, a reference to the given entity is removed from the active entity data structure.

This invention relates generally to blockchain implementations and is suited for, but not limited to, use with the Bitcoin blockchain. It can be used for the implementation of automated processes such as device/system control, process control, distributed computing and storage and others. The invention provides an event detecting, monitoring and/or counting mechanism. The event may be, for example, a vote, decision or selection which is made by a given entity. The invention provides a counting solution in which a computing resource, running simultaneously and in parallel to the blockchain, manages a loop-based operation. The computing resource continuously monitors the state of the blockchain as well as any other off-blockchain input data or source. The execution of the loop is influenced by the state of the blockchain. Each iteration of the loop that is executed by the computing resource is recorded in a transaction that is written to the blockchain. It is stored as a hash within the transaction's metadata. If the computing resource finds a transaction which contains a hash relating to the loop it accesses the relevant portion of code. The loop contains a conditional statement which enables the computing resource to decide which action to take. The condition may be dependent upon the state of the blockchain or any other data source. The action can be any type of action, on or off the blockchain. Thus, the combination of the computing resource and blockchain provide a Turing-

The present disclosure describes a method for managing a blockchain. The method includes receiving a user confirmed request for the transferring of a data package from a source address to a destination address. The method includes determining whether the source address and the destination address is authorized. If the source address and the destination address is authorized, then the method includes signing the partially signed contract to create a complete signed contract, transferring the data package to the destination address, and logging the data package and the complete signed contract to a centralized database. If at least one of the source address or the destination address is not authorized, then the method includes flagging the partially signed contract as incomplete, blocking the data package from being transferred to the destination address, and logging the data package and the partially signed contract to the centralized database.

0000 A system and method are disclosed for rendering consistent user interfaces stored in a blockchain smart contract. One asset may be sold on multiple websites using the same user interface rendered using metadata stored on a smart contract. A web application queries the smart contract for the rendering metadata. The web application generates a web element using metadata received from querying the smart contract. The web application renders the creator interface for display using the generated web element. For example, while an athlete may user a smart contract-rendered user interface to enable a consumer to purchase an NFT directly from their website, the athlete can also enable the same, smart contract-rendered interface to be available to consumers from other websites (e.g., websites for a sports organization, a sportswear company, etc.).

A system and method for accurate dividend distribution in investment products using proportional yield and temporal shifting. The disclosed system and method addresses challenges arising from real-time asset transfers and multi-day compounded rates. Specifically, the system calculates adjusted balances for investors by tracking ownership intervals across blockchain transactions, ensuring precise dividend distribution even during cross-chain transfers. It de-compounds multi-day rates provided by fund administrators into daily rates and schedules dividend payments accordingly, accounting for weekends, holidays, and other non-business days. By utilizing high-precision analytics and real-time synchronization between blockchains, the system ensures that dividend accruals are fair and accurate, even during asset transfers or when compounded rates span multiple days so that investors are paid equitably based on their actual holdings, regardless of transaction timing or cross-chain events.
