More on blockchain --- In an effort to better understand how blockchain works, I looked for some definitions online. Here are my takeaways (in simple words): 1. Blockchain is used to record and distribute information. The information cannot be edited or altered. 2. They generate trust with the need of a third party 3. They allow the exchange of data grouped in ‘blocks’ linked to one another. Each block store data. 4. The blocks of data are chained together in chronological order. 5. The data entered in a block is irreversible.<br /> The sources that I consulted are the following: https://www.pwc.com/us/en/industries/financial-services/fintech/bitcoin-blockchain-cryptocurrency.html https://www.investopedia.com/terms/b/blockchain.asp https://www.euromoney.com/learning/blockchain-explained/what-is-blockchain
