BLOCKCHAIN TRANSACTION CLEAN-UP SERVICE

Resumen de: WO2025119607A1

Methods, devices, and data structures for processing large volumes of transactions in blockchain nodes. Solutions are provided for transaction clean-up following receipt of a block announcement from another node. In one example, transaction identifiers in a list matching the local candidate block are marked if they match transaction identifiers in the announced block and, once the block is validated, the block assembly service uses unmarked transaction identifiers to build the new candidate block. In other examples, a candidate database of transaction identifiers is built during the mining phase and TxIDs are marked with an array identifier or a node identifier as arrays are announced by other nodes on the network. This may speed clean-up once the block is announced and reduces memory footprint for carrying out the post-solution marking of TxIDs as being included in the solved block.

Latency and computational performance on a blockchain

Resumen de: AU2025203696A1

Blockchain latency is improved by unclogging a mempool, which frees up electronic memory and reduces CPU usage and network bandwidth. Mining data of one or more initial blocks of a blockchain is accessed. The mining data reveals, for each miner, the time delay between individual transactions mined by that miner. A subset of miners is then determined to have lower time delays than miners not in the subset. Thereafter, a different random number is generated for each new block of the blockchain system to be mined. Based on a comparison of this random number and a predefined threshold, either an exploitation phase or an exploration phase is entered for the mining of each new block. In the exploitation phase, mining tasks are assigned only to the subset of the miners. In the exploration phase, mining tasks are assigned to both miners within the subset and miners not in the subset.

UNITY COIN

Resumen de: AU2023270357A1

UnityCoin can be utilized for various transactions within the platform, including the purchase of advertisement space, contributions to charitable causes, and other in-app acquisitions. The Intrinsic value of a Unity coin will be determined by the below formula: = 1 here Y(U) n(u) y(u) represents Value of one unity coin, g(t1 ) represents the intrinsic value added by trigger t,, and n (U) represents number of Unity coins mined The function g(ti) will have different formulae for each trigger to represent the value it adds to Unity. For example, in the example, when the trigger is adding a problem voice, then intrinsic value it adds is: gt =C(x) -C'(x) When the trigger is continuous self-improvement using Unity Assistant, the intrinsic value it adds is: g(t) =n (Ua) X ag X E where n (Ua) represents number of Daily Active Users interacting with Unity assistant, 'avg represents Average Interaction score as calculated by Unity Assistant, and E represents self-improvement constant as defined by Unity platform Figure 1
