This presentation aims at providing a brief introduction to distributed ledgers, and their underlying technologies, such as the blockchain, multisignature, and smart contracts.

Potential use-cases are presented, as well as current applications of the technologies.

Decentralized applications (DAPPS) promise to innovate the current business models, and create new ones.

Early adopters or investors should exercise due diligence, as the current platforms are still under heavy development.
