Filesign

Filesign is a substrate pallet which allows to create and store files with different metadata on blockchain

Main features:

• file versioning
• store file hashes for each version
• assign signers to files
• provide file signing

Add the pallet to the Substrate node template pallets folder.

Add the following snippets of code to the runtime/lib.rs:

use pallet_evercity_filesign;

impl pallet_evercity_filesign::Config for Runtime {
    type Event = Event;
    type Randomness = RandomnessCollectiveFlip;
}

construct_runtime!(
	pub enum Runtime where
		Block = Block,
		NodeBlock = opaque::Block,
		UncheckedExtrinsic = UncheckedExtrinsic
	{
        ...
        EvercityFilesign: pallet_evercity_filesign::{ Module, Call, Storage, Event<T> },
	}
);

Add the following dependencies to runtime Cargo.toml:

[dependencies]
pallet-evercity-filesign = { default-features = false, version = '0.1.3', git = 'https://github.com/EvercityEcosystem/filesign'}

Run:

cargo build --release
./target/release/node-template purge-chain --dev
./target/release/node-template --dev

Go to extrinsics for the locally running node

works with JUL template
