Multichain integration

Overview

Multichain is a collection of functions, types, interfaces, and runtimes that can be implemented for any blockchain. Those familiar with the Rosetta spec by Coinbase will note similarities in goals. However, multichain's scope is limited to accounts, contract calls, and sending transactions — there is no block data extraction. Moreover, the chain (Harmony) would have to implement the appropriate functions to Ren's multichain repo as a pull request and undergo their review. The Ren Project notes that once Harmony has integrated with the multichain API, we have the possibility for support in the RenVM.

Context

To help bridge the gap between Harmony and other chains, we must explore ways to integrate with chain agnostic interfaces. Having an API that is standard across multiple chains (notably BTC & ETH) will help reduce the friction of getting a

Install

1. Make sure you have docker installed.
2. Go to a directory you are comfortable with. For example cd ~/Desktop.
3. Download the funding script with the following comand:

curl -O https://raw.githubusercontent.com/harmony-one/dapp-curve-contracts/master/scripts/fund.sh && chmod +x fund.sh

Node API Overhaul

Last updated: Wednesday, July 8th, 2020.

Overview

The API layer of a Harmony node is its main interface with the outside world. Therefore, it must be consistent, robust, and well-documented in order to provide easy integration with developers who wish to build on Harmony.

Current issues with v1 & v2 of Harmony's JSON-RPC based API

• Inconsistancies of response types (hex v.s. hex string v.s. number) and names (cammelCase v.s. kebab-case v.s. snake_case).

Send transactions using the Harmony CLI from a CSV file

Install

0. (Optional) Open terminal and cd to wherever you want to install your CLI. Personally I like ~/bin.

mkdir -p ~/bin && cd ~/bin

1. Get the latest Harmony CLI version

curl -O https://raw.githubusercontent.com/harmony-one/go-sdk/master/scripts/hmy.sh && chmod +x ./hmy.sh && ./hmy.sh -d
