Abstract: An access control server may store a private cryptographic key. The private cryptographic key corresponds to a public cryptographic key. The public cryptographic key is stored on a blockchain as part of an autonomous program protocol. The access control server may receive access control setting related to the autonomous program protocol. The access control server may receive a request for accessing the autonomous program protocol stored on the blockchain. The access control server may review the request. The access control server may determine the request is in compliance with the policies specified in the setting. The access control server may create, using the private cryptographic key, a digital signature for the request and generate a response including the digital signature. A successful verification of the digital signature using the public cryptographic key stored in the autonomous program protocol is required by the autonomous program protocol to process the request.

Abstract: 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.

Abstract: An access control server may receive state information of an autonomous program protocol that is recorded on a blockchain. The access control server may generate a trace log associated with one or more transactions executed by the autonomous program protocol, the trace log comprising machine events executed by the blockchain, the machine actions associated with the one or more transactions. The access control server may extract a set of features from the trace log, wherein a feature in the set comprises a summary of a machine event executed by the blockchain. The access control server may input the set of features to a machine learning model to determine a threat nature associated with the transactions of the autonomous program protocol. The access control server may perform a responsive action to address the threat nature.
