Course description

So far, this learning path has been focused on blockchain-based distributed ledgers. This course goes beyond this view to discuss how the blockchain protocol can be replaced (using different underlying architectures), expanded (with second-layer protocols) or improved (using advanced cryptographic primitives) to overcome some of the limitations of blockchain technology.
