near-checksum

Implementation of a checksum any data on NEAR Protocol

Develop

make fix
make qa
make build
make clean

Run CI local

Installation act:

brew install act

Setup env vars:

echo "GITHUB_TOKEN=%GITHUB_TOKEN%" | tee .secrets

Run

act --help

Deploy stage

make deploy-force
accountId=ilyar.testnet
contractName=$(cat neardev/dev-account)
near state $contractName
near delete $contractName $accountId

Deploy testnet

make qa
make build
accountId=ilyar.testnet
contractName="checksum.$accountId"
near create-account --masterAccount $accountId $contractName 
near deploy --wasmFile build/checksum.wasm --accountId $contractName

Usage

near view $contractName has '{"hash": "c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2"}'
near call $contractName add '{"data": [102, 111, 111, 98, 97, 114]}' --accountId $accountId

near-checksum's Issues

Redundand hash data

You store redundant data.
You operate with hash as a String. But store as Vec<u8>

        let checksum = env::sha256(&data);
        ...
        if !self.hash_set.insert(&checksum) {
            env::panic(b"Failed to save checksum");
        }

You should store it as a String.

Change basic path for source file

Cargo.toml
remove:

path = "src/contract/main.rs"

you don't need to change default path src/main.rs.

Also your app is not executable.
So change src/main.rs -> src/lib.rs

Also change

version = "1.0.0-beta.0"

to

version = "0.1.0"

Also remove name from section:

[lib]
name = "checksum"
