lambda-chain

Haskell implementation of a simple blockchain

Main goals

Lambda Chain main goals are below, ordered by priority.

1. Lambda Chain: Proof-of-Work [Completed] The first part of research is to build a minimal viable blockchain, only core modules for demonstrating the research.

2. Lambda Chain: Cryptocurrency [Partial Completed] The 2nd part of research, is to build a digital asset-like / electronic cash working on top of lambda chain. Nodes in chain are also have capale to handle memory pool and higher level of interaction.

3. Distributed Ledger Technology [On plan] The completed chain should be a distributed database product, provide a small network with a append-only ledger(database)

4. Assets and Contracts

Install Lightning DB (lmdb)

Via Package Manager on Unix system (brew, yum, apt...)

brew install lmdb

or build from vcpkg on Windows

Packages needed

1. encode/decode and crypto

$ cabal install base16-bytestring cryptonite merkle-tree arithmoi

2. hashmap and system path

$ cabal install unordered-containers easy-file

3. database

$ cabal install lmdb

4. and network

$ cabal install network wai warp

Running Node

1. Load Dash interface
2. dash [port-number]
3. connect [host] [port]
4. transfer [address] [amount]
5. mine
