Description

One of the most important aspect in Blockchain space is security. During the past years have seen Decentralize application , as well as Blockchain protocol that got hacked just because of some vulnerabilities lying in their Systems (Smart Contract).

Repots have stated the total amount of funds stolen or hacked in Blockchain protocol including DeFi (Decentralized Finance ) in 2022 is over 2,7Billoions dollars . Since we know the TVL (total value lock) from Blockchains ( Ethereum , Binance , Solana , Polkadot , Cardarno etc..) exceed 50Billions dollars, we understand how important is security of Smart Contact.

Blockchain security is also important as it helps boost adoption, improve the solutions running on Blockchain (Applications), secure investor's funds. Considering a career in Blockchain especially in security makes you stand out from the crowd.

In this course we will go through :

Network Consensus vulnerabilities and see how they operate.
