Uke Human DNS ink! Smart Contract

Description

An ink! smart contract that maps cryptographic addresses to more human readable names, just like a DNS. Coined the "Human DNS", it essentially maps the hashes of unique, human readable ids to otherwise illegible addresses via a hash. With this verifiable mapping of addresses, client-side implementations can then look up other users and add them to their contacts, or write them a new message, or any other package of data in theory.

Requirements

• Rust & Cargo
• ink! CLI

For an extended guide, please view: https://ink.substrate.io/getting-started/setup. This is required before running, compiling, or running tests for this repository.

Building & Running Tests

To run the included unit tests, you can run

cargo +nightly contract test

To build the smart contract into a usable WASM executable, you can run

cargo +nightly contract build

Deploying to Substrate Contract UI

Firstly, install the substrate-contract-node to your commandline using cargo :

cargo install contracts-node --git https://github.com/paritytech/substrate-contracts-node.git --tag v0.17.0 --force --locked

Build the contract:

cargo +nightly contract build

Start your Substrate development node:

substrate-contracts-node --dev --tmp

Once it's started and you see blocks populating, navigate to https://contracts-ui.substrate.io/ and click the upper left and select Local Node.

You may now upload uke_human_dns.contract to the node via Add New Contract in the left pane. Click through the UI and upload the contract to the network.
