Protection of online applications and webpages using a blockchain

A computing system, comprising:

• at least one processor connected to at least one memory;
• a hash module stored on a non-transitory computer readable medium and including instructions that when executed by at least the processor cause the processor to hash computer code corresponding to network-accessible content to generate a hashed code, wherein the network-accessible content is to be hosted at a network address corresponding to a domain;
• and
• an encryption module stored on the non-transitory computer readable medium and including instructions that when executed by at least the processor cause the processor to:
• encrypt and sign the hashed code to generate an encrypted and signed hash, wherein the hashed code is encrypted using:
• (i) a private key associated with a source of the network-accessible content, and (ii) a public key associated with a registrar of the domain;
• and
• transmit, by at least the processor, the encrypted and signed hash and the domain to a blockchain, causing:
• (i) the blockchain to request validation the encrypted and signed hash by a terminal associated with a registrar of the domain;
• (ii) the terminal associated with the registrar to:
• (a) decrypt the encrypted and signed hash using the private key to obtain the hashed code, (b) attempt to validate an authenticity of the hashed code by determining whether a signature of the encrypted and signed hash corresponds to a party affiliated with the domain, and (c) control inclusion of the hashed code in a blockchain record based on a result of the attempt to validate the authenticity of the hashed code;
• (iii) the blockchain to transmit a domain confirmation request to a domain name server;
• and
• (iv) the domain name server to (a) determine whether the registrar matches a specific registrar linked to the domain in a data structure accessible to the domain name server, (b) transmit an objection to the blockchain, to interfere with inclusion of the hashed code in the blockchain record as a result of a determination that the registrar does not match the specific registrar.

A computer-implemented method, the method comprising:

• hashing, by at least a processor, computer code corresponding to network-accessible content to generate a hashed code, wherein the network-accessible content is to be hosted at a network address corresponding to a domain;
• encrypting and signing, by at least the processor, the hashed code to generate an encrypted and signed hash, wherein the hashed code is encrypted using:
• (i) a private key associated with a source of the network-accessible content, and (ii) a public key associated with a registrar of the domain;
• and
• transmitting, by at least the processor, the encrypted and signed hash and the domain to a blockchain, causing:
• (i) the blockchain to request validation the encrypted and signed hash by a terminal associated with a registrar of the domain;
• (ii) the terminal associated with the registrar to:
• (a) decrypt the encrypted and signed hash using the private key to obtain the hashed code, (b) attempt to validate an authenticity of the hashed code by determining whether a signature of the encrypted and signed hash corresponds to a party affiliated with the domain, and (c) control inclusion of the hashed code in a blockchain record based on a result of the attempt to validate the authenticity of the hashed code;
• (iii) the blockchain to transmit a domain confirmation request to a domain name server;
• and
• (iv) the domain name server to (a) determine whether the registrar matches a specific registrar linked to the domain in a data structure accessible to the domain name server, (b) transmit an objection to the blockchain, to interfere with inclusion of the hashed code in the blockchain record as a result of a determination that the registrar does not match the specific registrar.
