SEPARATING HASHING FROM PROOF-OF-WORK IN BLOCKCHAIN ENVIRONMENTS

Resumen de: US2025184117A1

Blockchain environments may mix-and-match different encryption, difficulty, and/or proof-of-work schemes when mining blockchain transactions. Each encryption, difficulty, and/or proof-of-work scheme may be separate, stand-alone programs, files, or third-party services. Blockchain miners may be agnostic to a particular coin's or network's encryption, difficulty, and/or proof-of-work schemes, thus allowing any blockchain miner to process or mine data in multiple blockchains. GPUs, ASICs, and other specialized processing hardware components may be deterred by forcing cache misses, cache latencies, and processor stalls. Hashing, difficulty, and/or proof-of-work schemes require less programming code, consume less storage space/usage in bytes, and execute faster. Blockchain mining schemes may further randomize byte or memory block access, further improve cryptographic security.

If the fraud risk score exceeds a threshold value, a fraud response is triggered.

METHODS AND DEVICES FOR PROPAGATING BLOCKS IN A BLOCKCHAIN NETWORK

Resumen de: US2025182103A1

Methods and devices for propagating blocks in a blockchain network. At a mining node, while hashing a first block header of a first candidate block, the mining node sends, to other mining nodes, a first message specifying transactions and their order in a first ordered set of transactions contained in the first candidate block. The mining also receives a second message specifying transactions and their order in a second ordered set of transactions contained in a second candidate block being mined by a second mining node. If the mining node succeeds in mining the candidate block it notifies other mining nodes by providing them with a coinbase transaction, hash value, and timestamp. If another mining node is successful, then the mining node receives information from the other mining node from which, in conjunction with the second message, it can assemble the second candidate block and validate it.

The processing device then generates an identity asset that includes the association for inclusion in an identity registry. The processing device performs a variety of analysis as part of maintaining the identity registry, such as generating segments of identity assets and generating rules to govern access and use of the identity assets. The processing device then grants access to the identity registry based on the rules.
