Justice recognizes this kind of proof-of-authenticity?

After the record is confirmed by the blockchain, you already have a legal proof of authenticity. To reinforce the legal validity of contracts, parties can prove their knowledge and agreement to the document content, ensuring international legal validity for your record.
Although there is no specific jurisprudence on the blockchain 'yet', a document digitally signed and certified on a public network, irrevocably, with the knowledge and agreement of all the parties involved about the document contents, it can be considered additional and complementary proof in cases of dispute.

Does BitRegistro replace the public registration or the registration of trademarks and patents?

Currently, this record does not exclude the need for registration in official agencies and government, but offers support and counter-proof in cases of dispute as the official channels do not provide a quick and efficient way to validate the authenticity of the information.

What is Blockchain?

Blockchain is a distributed database (ledger) of public accounting that records cryptocurrency transactions in a decentralized and distributed network. Each blockchain uses its own cryptocurrency. The system does not depend on trust between the different users (network nodes). Anyone can control and monitor a system node. The blockchain network operates autonomously without a central database or single central administrator. The blockchain runs and is maintained collectively by various nodes of the peer-to-peer network to record transactions, and uses open source encryption to provide basic security functions to ensure that the cryptocurrency can only be spent by the owner and avoid double spending, forgery and tampering databases. An innovative solution that performs open accounting without relying on a trusted central authority. - Source: Wikipedia
