English abstract

Blockchain, originally called block chain, is an ever-growing list of records called blocks that communicate with each other through encrypted messages. Each block contains a cryptographic hash of the previous block, a timestamp, and the transaction data. By design, a blockchain is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way," typically managed by a peer-to-peer network that adheres to a protocol for communication between nodes and validating new blocks. Once recorded, the data in a given block cannot be changed retroactively without changing all subsequent blocks, which requires network consensus.

Romanian abstract

Blockchain, denumit inițial lanț de blocuri, este o listă în continuă creștere de înregistrări numite blocuri, care comunică între ele prin mesaje criptografiate. Fiecare bloc conține un hash criptografic al blocului anterior, un marcaj de timp și datele tranzacției. Prin proiectare, un blockchain este "un registru deschis, distribuit, care poate înregistra tranzacțiile între două părți eficient și într-un mod verificabil și permanent", de obicei gestionat de o rețea peer-to-peer care aderă la un protocol pentru comunicarea între noduri și validarea de noi blocuri. După înregistrare, datele dintr-un bloc dat nu pot fi modificate retroactiv fără modificarea tuturor blocurilor ulterioare, ceea ce necesită consensul rețelei.
