Hey guys! Welcome back to a new episode on The 4Geeks Podcast. Today we are talking about Blockchain, and it can be used to disrupt some industries.

Banking, Supply Chain, Security, Insurance, Crowdfunding, Government, Health, Online Music and Real Estates are some industries that we talked about on this episode.


  • Citi Coin, from Citi Bank. (“equivalent to bitcoin”).

Blockchain-based systems don’t have a single place to attack due to the technology’s basic principles, where each block is immutable and cryptographic.

Each block has previous hash references (composed from the data)
Proof-of-work (latency) and proof-of-stake(based on percentage)


Fraud: $40B a year in loses for fraud, paperwork process increase fraud. Eliminate double booking, ownership and reduce premium division.
Health insurance: records secured and shared between.
