[Bounty] Stacking Pool

[willemneal]

NEAR Bounty Terms

Before beginning work on the bounty, you must submit a proposal. Only if your proposal is accepted will you be able to claim the reward of the bounty. In particular for this bounty you need to detail the testing you will use other than unit testing.

There should be at most 1 week between proposal is accepted and you start working on the bounty. It should take you at most 1 month to complete the bounty.

Description

For this bounty you will need to rewrite the Staking Pool into AssemblyScript making sure that they have the same API.

Context

With the new addition of includeBytes function in AssemblyScript, near-sdk-as should have enough parity with near-sdk-rs that the core smart contracts should be able to be written in AS. The trickiest part of the contracts are the cross contract calls. Rust provides a high level abstraction for working with promises. For an example for batch promise calls in AS see the sdk's repo here.

Relevant repos or issues

Core Contracts

API

Same as rust contracts.

Acceptance Criteria

• [ ] Including the unit tests
• [ ] Test contracts another way

Bounty

200 DAI

Proposal:

I plan to rewrite the Staking Pool into AssemblyScript making sure that they have the same API.

I plan to create unit tests and an integration tests in AssemblyScript deploying the contract in testnet, in a similar way the near-cli package test the near call functionality

As a second test strategy, I plan to use the test harness of the rust contract code, but using the .WASM file from the assemblyscript compilation. It seems that the rust test suite can be applied to a .WASM contract file generated by the AS compiler.

@luciotato I added an example contract and tests.

I took a detour and I'm making a rust parser (hand-coded PEG Parser)
The "parsing" part is mostly done (it was not easy, rust syntax is complex)
I'm starting now the "transpiling into AS" part.

This is the resulting AST for the Staking Contract up to level 3

Hi Willem!, I'm doing the hackathon. Will resume after that

@willemneal I'm stuck because to compute "shares" after a stake, I need to multiply 2 u128 into a u256 (2 big u128, will overflow).-
is there a way to do that in AssemblyScript? I don't see mul & div in u256, nor mul(u128,u128)->u256
It looks like those should be added to https://github.com/MaxGraey/as-bignum
