Abstract: In one embodiment, a method includes receiving a request to reissue a certificate for a smart contract, wherein an original certificate was previously issued for the smart contract, determining by a certificate authority that the smart contract is upgradeable and was modified after being issued or the original certificate was revoked, receiving a copy of updated source code of an updated version of the smart contract in a development environment by the certificate authority, determining whether the copy satisfies security criteria by the certificate authority, receiving an indication by the certificate authority that the updated smart contract was deployed on a first blockchain network, determining by the certificate authority that the updated smart contract deployed on the first blockchain network matches the copy of updated source code in the development environment, and issuing a reissue certificate for the updated smart contract by the certificate authority based on the determination.

Abstract: In one embodiment, a method includes sending a verification request for a certificate issued by a certificate authority by a first smart contract deployed on a first blockchain network by a first entity, wherein the certificate is associated with a second smart contract, and wherein the verification request includes a program address of the second smart contract and an address of a first root authority entity associated with the certificate authority, receiving a verification response by the first smart contract indicating that the second smart contract is associated with a certificate matching the program address and the address of the first root authority entity in the verification request, determining whether the second smart contract is upgradeable by the first smart contract, determining whether the certificate is valid by the first smart contract based on a determination of whether the second smart contract was modified after the certificate was issued.

Abstract: In one embodiment, a method includes receiving transaction data associated with a protected first function of a first blockchain transaction protocol by a cybersecurity authentication service of a blockchain cybersecurity platform, assigning a first authority classification to the protected first function based on a transaction protocol runbook comprising preconfigured conditions associated with the protected first function, accessing the transaction data via a cybersecurity authentication interface by a first cybersecurity authority having an authority classification corresponding to the first authority classification, determining that the protected first function should be authenticated by the first cybersecurity authority based on each preconfigured condition being satisfied, inputting an authentication of the protected first function via the cybersecurity authentication interface by the first cybersecurity authority, and transmitting a transaction bundle configured to update a second blockchain transactio

Abstract: In one embodiment, a method includes receiving transaction data associated with a protected first function of a first blockchain transaction protocol by a cybersecurity authentication service of a blockchain cybersecurity platform, accessing a transaction protocol runbook comprising preconfigured conditions associated with the protected first function, determining that each preconfigured condition is satisfied based on the received transaction data, generating transaction simulations for the protected first function based on the transaction data via a blockchain transaction simulation module, wherein each transaction simulation indicates predicted outcome states based on the protected first function being executed based on the received transaction data, determining that the protected first function should be authenticated based on the generated transaction simulations and the determination that each preconfigured condition is satisfied, and transmitting a transaction bundle configured to update a second block

Abstract: In one embodiment, a method includes receiving transaction data associated with a protected first function of a first blockchain transaction protocol at a proxy blockchain transaction protocol associated with a blockchain cybersecurity platform based on a persistent address associated with the proxy blockchain transaction protocol, wherein the proxy blockchain transaction protocol is configured to redirect the received transaction data to an address associated with a receiving node of the blockchain cybersecurity platform, receiving the redirected transaction data at the receiving node, accessing a transaction protocol runbook by a cybersecurity authentication service of the blockchain cybersecurity platform, wherein the transaction protocol runbook comprises preconfigured conditions associated with the protected first function, determining that the protected first function should be authenticated based on each preconfigured condition being satisfied, and transmitting a transaction bundle configured to update

Abstract: In one embodiment, a method includes receiving authorization by a certificate authority to access a specified development environment of a smart contract, receiving in the development environment a first copy of source code of the smart contract by the certificate authority authorized to audit the smart contract, generating an audit report for the smart contract by the certificate authority, receiving a second copy of source code of the smart contract in the development environment, wherein the second copy of source code is generated responsive to the audit report, determining that the second copy of source code satisfies the security criteria, receiving an indication that the smart contract was deployed on the first blockchain network, determining that the smart contract deployed on the first blockchain network matches the second copy of source code in the development environment, and issuing a certificate for the smart contract based on the determination.

Abstract: In one embodiment, a method includes accessing transaction data associated with a protected first function of a first blockchain transaction protocol by a cybersecurity authentication service of a blockchain cybersecurity platform, accessing a transaction protocol runbook comprising preconfigured conditions associated with the protected first function, determining that the protected first function is eligible to be analyzed by an automated decisional logic module based on the transaction protocol runbook, determining each preconfigured condition is satisfied based on the transaction data by the automated decisional logic module, generating an authentication object for the protected first function, generating signed transaction data based on the accessed transaction data and a private encryption key, wherein the signed transaction data is configured to update a second blockchain transaction protocol to indicate that the protected first function is authenticated, and transmitting a transaction bundle comprising

Abstract: In one embodiment, a method includes identifying first entities by a first root authority entity, authorizing one or more first entities to be certificate authorities by the first root authority entity, wherein each certificate authority is configured to audit a smart contract in a development environment before it is deployed on a first blockchain network and authorized to issue a certificate for each smart contract audited in the development environment based on a determination that the corresponding smart contract deployed on the first blockchain network matches the smart contract that was audited in the development environment, determining certificate authority authorization parameters are not satisfied for at least a first certificate authority, and revoking the certificate authority authorization for the first certificate authority by the first root authority entity, wherein each certificate issued by the first certificate authority prior to the revocation remains valid after the revocation.
