hósdagur 15.02.2018, kl. 16:30, Ovastova, Nóatún, Fróðskaparsetrið

Qin Xin, professari í teldufrøði á Fróðskaparsetrinum, fer hósdgain 15 februar at halda almennan fyrilestur við heitinum BlockChains and BitCoin.

Um fyrilesturin verður sagt: 

"A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography [this definition comes from Wikipedia]. The blockchain was introduced by an anonymous person or group known as Satoshi Nakamoto and implemented as the backbone of Bitcoin in which it records all transactions as the public ledger. However, because this ledger is distributed over a P2P network without of a trusted authority or central server, the participants have to agree on the validity of transactions before they can be recorded into the Bitcoin blockchain, which is achieved through a “mining process.” A “proof of work” that meets certain requirements is created during the mining, which is costly and time-consuming to produce but can be easily verified by other participants. To really understand what is the blockchain and Bitcoin, we need to understand how it works at a techincal level. In this talk, Qin will cover the important topics including bitcoin technology, decentralized ledger, block structure and merkle tree, bitcoin address, proof-of-work, mining puzzle, smart property, and potential blockchain applications. Other advance issues including the incentive-compatible property of bitcoin, alternative mining puzzles, quantum attacks on bitcoin, quantum-resistant cryptocurrency, and quantum money may also be addressed."
