Blockchain is presented as a revolutionary technology for digital trust. And it is! Usage cases are soaring, and all the activity sectors are getting to grips with them. Sometimes obvious, sometimes strange, even useless, these tests bring innovation to our daily lives and in the medium term.

The fundamentals of blockchain are theoretically solid and rely on cryptographic mechanisms which were developed and mastered many years ago. In light of this, their main point of weakness lies in the manner with which the implementation of Blockchain is realized. Recent attacks have highlighted these limits, in particular that which is aimed at the Ethereum chain and its famous “smart contracts”.

This RiskInsight letter aims to interpret these evolutions and their function, to explain the risks and the documented attacks to allow you to find the right balance between risk and innovation.
