This document discusses BMLite, a lightweight web client for the Bitmessage network. It aims to address issues with the full Bitmessage client, which requires downloading the entire message history. BMLite would allow users to send and receive Bitmessages through a web interface hosted on a server, avoiding the need to set up the full client locally. It proposes using AngularJS, Node.js, and MongoDB to build the lightweight web client platform.

2. Introduction
Problem:

NSA security fallout

How perfect is Https – centralized authority

How perfect is PGP/GPG – sender/receiver is
not encrypted

3. 
Proposed Solution:
Jonathan Warren's Bitmessage

Based on Satoshi Nakamoto's (a pseudonym of
a developer) Bitcoin concept

4. Bitcoins

Peer-to-peer network concept

Concepts: Transactions, Blocks, Proof-of-work

Transactions: The basic unit in Bitcoin concept
[Messages: The basic units in Bitmessage
concept]

Blocks: Makes sure that duplicates are not
created in the Bitcoin network

Proof-of-work – originated in HashCash by
Adam Back

5. HashCash

Proposed by Adam Back in March 1997

Protects the email system from Spamming and
Denial-of-Service attacks

This concept is extensively used in Bitmessage

6. Problem

In Bitmessage or Bitcoin system, the user has
to download the respective client into his
system

The first time download downloads all the
existing Bitmessages into the user's system

This is an issue because a naïve user may not
be comfortable to set it up

7. Solution

A web client that holds all the Bitmessage data

This web application is deployed on a server
which contains all the messages in the
Bitmessage network

A user logs into this system using his userID
and password and sends/receives messages
from this web client

8. Platform

The (hippie) development stack:
− AngularJS
− Node.js
− MongoDB
