About Utility

Utility's mission is to stimulate community-led innovation for the benefit of people worldwide.

To realize this mission, Utility provides a platform where developers and entrepreneurs can build applications that put users back in control of their data and assets. This is a core tenet of the ["Open Web" movement][open-web-url].

A key component of utnet is utility, a blockchain-powered unc-infra.tructure for serverless applications and smart contracts. Utility aims to offer the ease-of-use and scalability of modern PaaS like Firebase, but at a fraction of the cost of blockchains like Ethereum.

Installation

The easiest way to join the network, is by using the make release command or download release binaries, which you can install as follows:

# testnet node init directly use binaries
unc-node --home ~/.unc init --chain-id testnet --download-genesis --download-config
# download snapshot data （optional）## install rclone 1.66.0 or beyond```sh# Mac $ brew install rclone# Linux$ sudo apt install rclone$ mkdir -p ~/.config/rclone$ touch ~/.config/rclone/rclone.conf## rclone config[unc_cf]type = s3provider = Cloudflareendpoint= https://ec9b597fa02615ca6a0e62b7ff35d0cc.r2.cloudflarestorage.comaccess_key_id = 2ff213c3730df215a7cc56e28914092esecret_access_key = b28609e3869b43339c1267b59cf25aa5deff4097737d3848e1491e0729c3ff6cacl = public-read## download data $ rclone copy --no-check-certificate unc_cf:unc/latest ./$ latest=$(cat latest)$ rclone copy --no-check-certificate --progress --transfers=6 unc_cf:unc/${latest:?}.tar.gz /tmp## un archive snapshottar -zxvf /tmp/${latest:?}.tar.gz -C /tmp && mv /tmp/${latest:?}/data ~/.unc## on ～/.unc dir touch file `validator_key.json` (optional){"account_id": "miner-addr""public_key":"ed25519:2yMvZrTtjgFMtcpE12G3tdt7KsYKdKE6jufRnz4Yyxw3","private_key":"ed25519:3NVx4sHxBJciEH2wZoMig8YiMx1Q84Ur2RWTd2GQ7JNfWdyDxwwYrUR6XtJR3YcYeWh9NzVEmsnYe2keB97mVExZ"}# node run$ unc-node --home ~/.unc run
