vStore: verifiable store

vStore is a Go application built using Cosmos SDK. It focusses on providing:

• data integrity: attaching timestamp and signature information to data ; and
• data redundancy: running a vstore application on top of CometBFT nodes ; and
• data availability: data is available from any supporting CometBFT nodes ; and
• data security: the blockchain is not used to store your data!

The vStore is released as an ABCI application which commits cryptographic proof alongside data sets to ensure that they are untouched and always verifiable.

This software implements a first draft of vfs as an integral part of the vstore application, this may change in the future.

Usage

A reference documentation is deployed at https://vfs.zone.

Usage documentation can be found in this document or in the cmd package documentation which also lists some examples here.

Install

To start running an instance of vstore, execute the following command:

go install github.com/securesharelabs/vstore@latest
vstore --home /tmp/.vfs-home --socket unix://vfs.sock

You can interact with vfs using any ABCI client implementation or you can run a CometBFT node from the same directory that connects with this ABCI application:

export COMETBFT="github.com/cometbft/cometbft/cmd/cometbft@v0.38.10"
go run ${COMETBFT} init --home /tmp/.cometbft-home
go run ${COMETBFT} node --home /tmp/.cometbft-home --proxy_app unix://vfs.sock

Your vstore instance is now available through the CometBFT RPC, and using the different subcommands available with vstore, e.g.:

# Sending a transaction
vstore factory --home /tmp/.vfs-home --data "Data that will be signed" --commit

# Querying app info (includes AppHash)
vstore info --home /tmp/.vfs-home

# Querying a transaction hash (as returned by factory)
vstore query --home /tmp/.vfs-home --hash TRANSACTION_HASH_HEX

Developer notes

This package is released as github.com/securesharelabs/vstore and is composed of two implementation subpackages:

• github.com/securesharelabs/vstore/vfs: A first draft implementation for vfs.
• github.com/securesharelabs/vstore/cmd: A CLI for storing data with vStore.

Note that it is probable that the vfs subpackage implementation gets extracted in later iterations of the project.

You can install dependencies and run the unit test suite using:

go get
go build
go test github.com/securesharelabs/vstore/vfs -v -count=1

Reference documentation

You can generate the reference documentation locally using github.com/johnstarich/go/gopages.

Install gopages using go install -u github.com/johnstarich/go/gopages. Then generate the static reference documentation in a docs folder using the following command:

gopages -out docs/
