ADNL over TCP implementation in C#

[purpleguy99]

Summary

The development of an ADNL over TCP implementation is crucial for the TON ecosystem, as it provides a secure, efficient, and reliable communication protocol between nodes. By creating an ADNL over TCP implementation, developers will be able to easily integrate this protocol into their projects and improve the overall performance and security of their applications.

Context

ADNL (Abstract Datagram Network Layer) is an essential protocol for TON, which enables secure and efficient communication between nodes. Currently, there is a lack of an easy-to-use implementation of ADNL over TCP, which makes it difficult for developers to adopt this protocol and leverage its benefits.

This proposal aims to create an ADNL over TCP implementation, which will make it easier for developers to incorporate ADNL into their projects and improve the overall performance and security of the TON ecosystem.

Goals

Implement ADNL over TCP:

• Generate ADNL address from key
• Send messages (client side)
• Receive messages (server side)
• Encrypt and sign messages, Diffie Hellman
• Packet data (de)serialization

Implement LiteClient over ADNL:

• LiteServer methods provided in lite_api.tl
• TL data (de)serialization

Estimate suggested reward

2.250 USD in TON

@Naltox what do you think?

Well, I hope the C# SDK will develop, it greatly simplifies the life of indie Unity developers :)

The proposal looks constructive and timely.
The TON development toolchain keeps expanding with new development tools, and some of them will need the client-side module to to interact with blockchain natively.
C#/.NET also seems like a good choice: the managed language with clear structure and semantics leaves less room for subtle bugs.

Done! I have released v0.1.0 of the ADNL SDK for C#.

Ton docs successfully updated - ton-community/ton-docs#420

Based on the fact that without implementing a Lite Client for this library, it will be less used, I suggest you add a Lite Client implementation to the conditions for performing this task.

It will include the implementation of the main methods - sending and receiving Lite Server data presented in the topic
https://github.com/ton-blockchain/ton/blob/ad736c6bc3c06ad54dc6e40d62acbaf5dae41584/tl/generate/scheme/lite_api.tl#L62-L84

Additional suggested reward - 250 USD in TON.
Estimated development time is 4 days.

I have add lite client wrap for this library.
