Blockchain Address and Owner Verification System and Method

Glossary

Term Definitions Blockchain A growing list of records, called blocks, that are linked together using cryptography, including cryptographic hashes. Block A single record in a blockchain that contains a timestamp, transaction data, and a cryptographic hash of the previous block. Node In this context, a block in a blockchain, or a node in the Lightning Network. Blockchain Address A unique identifier associated with a blockchain node that is used to receive and send transactions. Authentication Certificate A digital certificate issued by an authentication server that verifies the identity of an entity associated with a transaction. X.509 Certificate A widely used digital certificate standard used in public key infrastructure (PKI). Extension Fields An optional field in an X.509 certificate that is used to include additional information. Authentication Service An entity or organization that issues and manages digital certificates. Public Key A key used to encrypt messages that can be accessed by anyone. Private Key A key used to decrypt messages that is kept secret by the owner. Lightning Network A secondary protocol built on top of the underlying blockchain that allows for faster and cheaper transactions. Channel A payment channel established between two users in the Lightning Network that is secured by collateral. Offline A transaction or operation performed outside of the blockchain. Funding transactions are on-chain transactions used to create channels in the Lightning Network. Double spending is a fraudulent act in a blockchain network where the same digital currency is spent twice.

Answers

The core characteristics of blockchain technology are decentralization, transparency, and immutability. Data is linked together in blocks, and each block contains a cryptographic hash of the previous block, ensuring the integrity of the data.

Bitcoin mining ensures the security and integrity of the network by solving complex mathematical problems to verify and add to the blockchain. In return, miners are rewarded with Bitcoin.

Blockchain technology has advantages in security, transparency, and censorship resistance, but its transaction speed is slower and less scalable than centralized systems.

An attestation certificate is a digital document issued by a trusted third party to verify the identity of an entity. In blockchain transactions, attestation certificates can be used to verify the identity of the counterparty to the transaction and prevent fraud.

An X.509 certificate can contain information such as the entity's name, email address, public key, organizational information, and digital signature to verify the entity's identity.

The system described in this article associates an address with a specific entity by including the blockchain address in an attestation certificate. The attestation server verifies the identity of the entity and issues the certificate to the entity.

A QR code can store an attestation certificate or a link to the location where the certificate is stored. Users can scan the QR code with a blockchain-enabled device to verify the certificate and confirm the identity of the entity.

A receiver can verify the sender's identity by requesting the sender to provide an attestation certificate containing its blockchain address. The receiver can verify the authenticity and validity of the certificate to ensure that the address belongs to the legitimate sender.

In the Lightning Network, a node can establish and verify its identity using an authentication certificate containing its node ID. Other nodes can verify the certificate, confirm the node's identity and establish a secure payment channel.

The system and method described in this paper improve the security of blockchain transactions and reduce the risk of fraud and identity theft by associating blockchain addresses with verified entity identities.
