In their relatively short lifespan, blockchain technologies have already undergone significant milestones. Bitcoin’s blockchain, often referred to as Blockchain 1.0, features a simple database ledger that records transactions in a chronological order and represents the state of the network to participants. Ethereum, or Blockchain 2.0, introduced the notion of smart contracts. Microsoft’s Bletchley Project introduces a new modular architecture which might mark a new milestone for blockchain technologies.
Marley Gray, Principal Program Manager Blockchain at Microsoft, joins us to talk about Microsoft’s approach to blockchain architecture. With enterprise in mind, Bletchley introduces the concept of “Cryptlets”, the core building blocks for introducing a secure middleware tier into blockchain application infrastructure. These computational units, running off-chain, on secure trusted container enclave hardware, could provide trusted data to on-chain smart contract logic.
