Understanding Blockchain Technology and How To Get Involved

  1. 1. Workshop “Open Education” #eLSE2018 Conference, Bucharest Romania, April 19-20 Prof.dr.ing. Carmen Holotescu "Ioan Slavici" University of Timisoara, Romania Understanding Blockchain Technology and How To Get Involved
  2. 2. Content 1. Blockchain technology 2. Blockchain impact 3. Blockchain in Romania 4. Blockchain in education 5. The need for Blockchain learning 6. Getting involved
  3. 3. https://github.com/trottier/original-bitcoin Definition (1) The blockchain term, originally block chain, was first coined in 2009, by (the still unknown) Satoshi Nakamoto, in the original source code for the virtual currency Bitcoin: "Nodes collect new transactions into a block, hash them into a hash tree"; "when they solve the proof-of-work, they broadcast the block to everyone and the block is added to the block chain." (Nakamoto, 2009). http://www.metzdowd.com/pipermail/cryptography/2008- October/014810.html
  4. 4. Definition (2) Blockchain technology enables the creation of a decentralized environment, where the cryptographically validated transactions and data are not under the control of any third party organization. Any transaction ever completed is recorded in an immutable ledger in a verifiable, secure, transparent and permanent way, with a timestamp and other details. In March 2018, Merriam Webster Dictionary added the definitions for Blockchain, Cryptocurrency and Initial Coin Offering (ICO). twitter.com/MerriamWebster/status/970667988964831232
  5. 5. Technology Explaining decentralization, Vitalik Buterin (24y), the creator of Ethereum, states that it assures fault tolerance, attack resistance and collusion resistance. Also, blockchain is decentralized on two of the three possible axes in software decentralization: • politically decentralized - no one controls it; • architecturally decentralized - no infrastructural central point of failure; • logically centralized - there is one commonly agreed state and the system behaves like a single computer. https://medium.com/@VitalikButerin/the-meaning-of- decentralization-a0c92b76a274 Ethereum (ethereum.org) is an open-source blockchain platform, described in a white paper by Vitalik Buterin in 2013 and launched in 2015, and is designed for a large variaty of applications, as opposed to the Bitcoin platform, mainly crypto-currency oriented.
  6. 6. How a blockchain works http://usblogs.pwc.com/emerging-technology/a-primer-on-blockchain-infographic/ http://usblogs.pwc.com/emerging-technology/category/blockchain/ Blockchain Demo https://anders.com/blockchain Mining: process of adding transactions to a blockchain by hash verification processes, with a high consume of hardware, energy, time. A new block: created on Bitcoin network at each ~ 10 min (https://blockchain.info/stats), on Ethereum network at each ~ 10 s (https://ethstats.net).
  7. 7. Advantages — self-sovereignty - users identify themselves and maintain control over the storage/management of personal data; — trust - the technical infrastructure offers secure operations(payments or issue of certificates); — transparency and provenance - to perform transactions in knowledge that each party has the capacity to enter into that transaction; — immutability- records are written and stored permanently, without the possibility of modification; — disintermediation- no need for a central controlling authority to manage transactions or keep records; — collaboration - ability of parties to transact directly with each other without the need for mediating third parties.
