An access control server may receive, from an access requester, an access request for accessing a protected autonomous program protocol stored on a blockchain. The access control server may analyze parameters related to the access requester to determine whether the access requester is authorized to access the protected autonomous program protocol. An access control server may generate a cryptographic signature associated with the access request. An access control autonomous protocol recorded on the blockchain may receive the cryptographic signature, verify the cryptographic signature, and store proof of authorization in association with the protected autonomous program protocol. The proof of authorization is accessible by the protected autonomous program protocol to verify that the access requester is authorized to access the protected autonomous program protocol.

Embodiments are directed to generating and training a distributed machine learning model using data received from a plurality of third parties using a distributed ledger system, such as a blockchain. As each third party submits data suitable for model training, the data submissions are recorded onto the distributed ledger. By traversing the ledger, the learning platform identifies what data has been submitted and by which parties, and trains a model using the submitted data. Each party is also able to remove their data from the learning platform, which is also reflected in the distributed ledger. The distributed ledger thus maintains a record of which parties submitted data, and which parties removed their data from the learning platform, allowing for different third parties to contribute data for model training, while retaining control over their submitted data by being able to remove their data from the learning platform.

Systems and methods for novel uses and/or improvements to blockchains and blockchain technology. As one example, systems and methods are described herein for self-validating digital records that may be transferred in real-time through a cross-network registry. For example, in a conventional system, minting a token (e.g., a digital record) involves writing a self-executing program that defines the transfer rules of the digital record. Once the self-executing program is written, it is deployed on a blockchain, and the digital record is minted by publishing it to a blockchain.

A computer-implemented method for enabling elliptic curve arithmetic to be performed using blockchain transactions. A first script comprising a modular inversion script is generated. The modular inversion script is configured to obtain a target integer x, a modulus value p, and a pair of indices for a component of an addition chain identifying a pair of pervious components which, when summed, equal the component of the addition chain. A modular inverse is generated by computing the exponentiation of x to the reduced modulus (p−2) using the addition chain. For each component of the addition chain for 3≤i≤l, each multiplier value is calculated by selecting the multiplier values associated with the pair of indices and multiplying the selected multiplier values to generate the respective multiplier value for the component. For i=l, a remainder of the multiplier value with respect to the modulus value is computed.
