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.

The present invention relates to a system and method for monetizing access to data using a blockchain-based framework with hardware secure enclaves (HSEs). The system enables data owners to securely store and control access to their data while ensuring payment for access through blockchain smart contracts. The system comprises a hardware secure enclave configured to lock data off-chain, store it securely, and provide cryptographic proof of data properties to authorized parties. Data access is monetized through the submission of funds to a smart contract, with payment verified on-chain and processed by the enclave. The system utilizes unique enclave signatures to manage notifications and triggers related to data access requests. Furthermore, the system employs blockchain relayers to ensure timely communication and transaction verification. A universal attestation process is used to ensure the integrity of the enclave's code. This invention provides a secure, efficient, and scalable solution for monetizing data access, leveraging secure enclave technology and blockchain for transparent and tamper-resistant transactions.

A method for detecting fraud across networks of interconnected smart contracts on a blockchain network, including constructing a graph representation of nodes and node edges representing smart contracts and interactions therebetween on a blockchain network. New smart contracts are added to the graph representation which is updated to reflect updated edges. Pattern recognition algorithms are applied to the graph database to identify and flag sub-graphs suggesting potential fraud. Filtering smart contracts gather forensic data about each smart contract comprised by the flagged sub-graph. A fraud risk score is determined by analyzing the forensic data. If the fraud risk score exceeds a threshold value, a fraud response is triggered.

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 present invention relates to a system and method for enhancing the security of smart contracts within blockchain networks by utilizing a hardware secure enclave for monitoring and suspending contract activities in response to detected security breaches. The system establishes a trust relationship between the hardware secure enclave and the smart contract, providing the smart contract with a unique enclave signature to ensure secure communications. A modular data monitoring application within the enclave is configured to detect suspicious activities, while an attestation process ensures the integrity of the enclave's code. Upon detecting a security threat, the system initiates a pause function to suspend contract operations and mitigate potential damage. The invention further leverages blockchain relayer modules to witness and transmit contract activity, and consensus mechanisms such as Proof-of-Work (PoW) or Proof-of-Stake (PoS) for transaction verification. This method provides a scalable, secure solution for preventing attacks on smart contracts and safeguarding digital assets in decentralized applications.

Techniques for generation of a unified identity registry are described that support integration and analysis of non-blockchain based user data and blockchain-based user data. A processing device, for instance, monitors an interaction between a client device associated with a user and a digital service provided by a digital service provider. Based on the interaction, the processing device determines a non-blockchain based identifier as well as a blockchain based identifier associated with the user and generates an association between the identifiers. 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.
