ADAPT - A Decentralized Application Programming Toolkit: Vision, Motivation, Architecture Today's development of decentralized applications is most often based on using large generalized blockchain networks, such as Ethereum, EOS or Dfinity. ADAPT offers an alternative: a way to launch small independent blockchain networks customized for the needs of a specific decentralized use case. We will discuss the reasoning behind this choice, the questions of alignment between stakeholder (broken in the current approach), topics of decentralized code reuse, surface of attack, and miner incentives. The talk will take the audience through the thinking that leads to the design of the next generation of blockchain software.
