Sheldrake

About

Sheldrake is a blockchain demo network that implements a cryptocurrency(first generation) example without a merkle tree, smart contracts, sidechain and a wallet. The main motivation was practice ocaml, functional programming, blockchain concepts and decentralized applications.

Dependencies

• OCaml 4.12.0
• Dune 2.9.1
• GCC 11.1.0

Compile and Run

On root

 $ dune build

to compile(some warnings due to C interfaced code) and

$ dune exec sheldrake

to run.

How to run properly

• You'll need to change the port and execute in different terminals to check the requests working between executions.
• If you have more than one machine you can try to execute in each one and see the requests with server side logs(it's printed in every request).
• You can just execute one instance and test the endpoints with something like postman(Remember to add the header "client" in the request).
