Security, privacy and scalability in blockchain technologies
Blockchain technologies have rapidly acquired popularity and promise to become one of the pillars of the digital society. They, however, are not immune from open challenges in terms of security, privacy and scalability. First, the complexity of blockchain applications makes their security analysis prohibitive, which may lead to coin losses by honest users. Second, the fundamental requirement of including every single transaction in the blockchain for transparency is at odds with the privacy of transactions and users. Last, but not least, storing all data in the blockchain creates severe scalability issues: currently, blockchain technologies typically support a dozen transactions per second, which is far from the throughput of other payment systems available today.
