A blockchain is a system that is used in cryptocurrency to record and save data of a person’s information and transactions. It is a recording system that also blocks and makes it difficult to cheat or hack the system.

Blockchaining is used in cryptocurrency to protect the user’s data and make sure the user does not exploit any cheats or hacks to benefit themselves. 

Large companies including Amazon, Microsoft, Walmart, PayPal, and Samsung use blockchains to secure transactions.

Blockchains are one of the biggest factors in cryptocurrency, as they record transactions between currencies and support big cryptocurrencies like Bitcoin.

Diego Hernandez, a WJPS junior stated, “I don’t think that it could be a safe idea as since this is a part of cryptocurrency, the idea of cryptocurrency has always been like a double edged sword. I personally don’t invest in crypto, but Blockchain might do a good job if they know what they’re doing. Besides that, I’m still positive that they can find a way.”

“I think it’s smart for cryptocurrency investors.” Giovanni Duran, another WJPS junior said.
