4. Blockchain 101 - RelevantAspects • Values: Decentralization, transparency, security and privacy. • DLT: Distributed Ledger Technology. • Decentralized Database • Transparency: although the information (or blocks) is not on any server, every user (or node) has access to a complete copy of the information registered. Nodes participate in Blockchain administration through consensus mechanisms - which vary among Blockchains and are central to reliability

5. Blockchain 101 - RelevantAspects • Immutability: the concept is related to the fact that each new information (or block) is associated with the previous block in a verifiable way, which generates a unique sequence distributed through all users of the network - thus guaranteeing inviolability.

6. Blockchain 101 - RelevantAspects • Cryptography: from the Greek "kryptós" meaning hidden and "graphene" meaning writing, cryptography is the science that transforms information into numbers and letters unintelligible to those who do not have the key, or formula, to read the message. • Values: Decentralization, transparency, security and privacy.

7. Smart Contracts • Nick Szabo • juristandcomputerscientistwhopioneeredcryptocurrencies. • coinedtheconceptof “smartcontract” in 1994: • “acomputerizedtransactionprotocol for thepurposesofcontractualobligationsfulfillment, reducingtheneed for reliableintermediaries, breachesandrelatedproblems, whetheraccidentalormalicious.”

8. Smart Contracts

9. BrazilianScenario: Receptiveness • Government and Judiciary • Brazil has a public key to sign documents. • BNDES / Petrobras initiatives to be further discussed • Blockchain to register legal proofs • Notary Offices • Civil Law: our legislation may already have what it takes to accept smart contracts • Under civil law, to be deemed valid, a contractual agreement must observe: • Agent capability (e.g. age / mental condition) • Licit, possible and determined object • Its form should either be expressly provided for or not expressly forbidden by law • Loophole • Rulings • Brazilian Supreme Court decided on Sept. 20 that “electronic agreements” may, under certain circumstances, be fully enforced in the judiciary even without the witnesses signature (something our legislation requires for a more straightforward judicial procedure in this matter).
