Blockchain technology is extremely fascinating... has captured our imaginations because of its huge potential to revolutionize industries such as logistics, food safety, music, insurance, banking, and even voting systems; however, its adoption is still very scarce. The reason is simple: blockchains are complex to use by end users.

During recent years, decentralized applications (DApps) have been emerging as candidates to change the rules of the game, mainly because of their ease of use and capability to leverage the full power of blockchains. The big question is... are DApps really secure?

This presentation will show how Ethereum-based DApps work, the technology behind them and some of their most common vulnerabilities. The ultimate goal will be to understand how to attack these applications and, especially, what to do to be protected.
