This project has been introduced by Microsoft, indicating the commitment by Microsoft to blockchain technology.
Bletchley allows the use of Azure cloud services to build blockchains in a user-friendly manner.
A Complete Guide to Understanding This Blockchain Concept
A major concept introduced by Bletchley is called cryptlets, which can be thought of like an advanced version of Oracles that reside outside the blockchain and can be called by smart contracts using secure channels.
These can be written in any language and execute within a secure container.
There are two types of cryptlets: utility cryptlets and contract cryptlets.
The first type is used to provide basic services such as encryption and basic data fetching from external sources, whereas the latter is a more intelligent version that is created automatically when a smart contract is created on the chain and resides off the chain but still linked to the on-chain contract.
Due to this off-chain existence, there is no need to execute the contract cryptlets on all nodes of the blockchain network.
Therefore, this approach results in increased performance of the blockchain.
