🌿CoLink Overview

CoLink is a simple, secure, and flexible decentralized programming abstraction. It contains

• A concise interface and workflow design for the orchestration of decentralized protocols
• A secure gateway server implementation that facilitates decentralized protocol executions
• SDKs in multiple languages for writing applications or cryptographic protocols that involve multiple participants.

In addition, there are also many existing protocols built on CoLink that extend its functionality and improve its usability.

❔What is Decentralized Programming

In Traditional Programming 🖥️**…**

A user often wants to implement a certain function to describe a procedure to convert certain input to output. Normally,

• The function is executed on one machine.
• The machine have full access to the input and the computation procedure.
• There is less trust required as the only user owns the machine.

In Decentralized Programming 🌐…

There are multiple users interested in collaboratively execute a protocol that take private inputs from different users and generate potentially different outputs for them. Often times,

• The protocol involves multiple machines from user running as the same of different roles.
• The machines cannot access private inputs from others and often cannot observe a global intermediate states.
• Depending on the collaboration goals, users may or may not trust each other to a certain degree.

🍎Examples of Decentralized Programming

There are many example applications and systems that are suitable for a mindset of decentralized programming. Normally, if the scenario involves multiple participants with potentially different interests, requires privacy, or needs enhanced security provided by a committee, one may consider decentralized programming to simplify their design thinking procedure. Also, from the technical perspective, if the system requires multiple rounds of communication, has a complicated workflow that depends on dynamic decisions from different users, or needs to manage storage on different servers without being able to copy things around, decentralized programming can probably simplify the interfaces and the primitives.
