Spaces Virtual Machine (SpacesVM)

Authenticated, Hierarchical Key-Value Store w/EIP-712 Compatibility, State Expiry, and Fee-Based Metering

Avalanche Subnets and Custom VMs

Avalanche is a network composed of multiple sub-networks (called subnets) that each contain any number of blockchains. Each blockchain is an instance of a Virtual Machine (VM), much like an object in an object-oriented language is an instance of a class. That is, the VM defines the behavior of the blockchain where it is instantiated. For example, Coreth (EVM) is a VM that is instantiated by the C-Chain. Likewise, one could deploy another instance of the EVM as their own blockchain (to take this to its logical conclusion).

AvalancheGo Compatibility

[v0.0.1] AvalancheGo@v1.7.0-v1.7.4
[v0.0.2] AvalancheGo@v1.7.5-v1.7.6
[v0.0.3] AvalancheGo@v1.7.7-v1.7.9
[v0.0.4] AvalancheGo@v1.7.10
[v0.0.5] AvalancheGo@v1.7.11-v1.7.12
[v0.0.6] AvalancheGo@v1.7.13-v1.7.18
[v0.0.7] AvalancheGo@v1.7.13-v1.7.18
[v0.0.8] AvalancheGo@v1.8.0-v1.8.6
[v0.0.9] AvalancheGo@v1.9.0-1.9.1
[v0.0.10] AvalancheGo@v1.9.2

Introduction

Just as Coreth powers the C-Chain, SpacesVM can be used to power its own blockchain in an Avalanche Subnet. Instead of providing a place to execute Solidity smart contracts, however, SpacesVM enables authenticated, hierarchical storage of arbitrary keys/values using any EIP-712 compatible wallet.

Authenticated

All modifications of storage require the signature of the owner of a "space".

Hierarchical

Owners can modify any key in their "space" (ex: owner/*), however, no one else can.

Arbitrary Key/Value Storage

As long as a key is ^[a-z0-9]{1,256}$, it can be used as an identifier in SpacesVM. The max length of values is defined in genesis but typically ranges between 64-200KB. Any number of values can be linked together to store files in the > 100s of MBs range (as long as you have the SPC to pay for it).

EIP-712 Compatible

wallet_signing

The canonical digest of a SpacesVM transaction is EIP-712 compliant, so any Web3 wallet that can sign typed data can interact with SpacesVM.

EIP-712 compliance in this case, however, does not mean that SpacesVM is an EVM or even an EVM derivative. SpacesVM is a new Avalanche-native VM written from scratch to optimize for storage-related operations.

Demo: tryspaces.xyz

What better way to understand how the the SpacesVM works than to see it in action? Well anon, you are in luck!

You can try out the SpacesVM at tryspaces.xyz. All you need is a EIP-712 Compatible Web3 Wallet (like MetaMask) and some SPC (all 973k of you that interacted with the C-Chain more than 2 times got 10k SPC to get you started).

This demo is running as an Avalanche Subnet on Fuji. It is ALPHA LEVEL CODE and may be restarted/have a few bugs in it. It exists for demonstration purposes ONLY but could be extended to run as a production-level Subnet on Avalanche Mainnet.

How it Works

Claim

Interacting with the SpacesVM starts with a ClaimTx. This reserves your own "space" and associates your address with it (so that only you can make changes to it and/or the keys in it).

Reserved Spaces

Spaces of length 66 (0x + hex-encoded EVM-style address) are reserved for address holders. Only the person who can produce a valid signature for a given address can claim these types of spaces.

Set/Delete

Once you have a space, you can then use SetTx and DeleteTx actions to add/modify/delete keys in it. The more storage your space uses, the faster it will expire.

Content-Addressable Keys

To support common blockchain use cases (like NFT storage), the SpacesVM supports the storage of arbitrary size files using content-addressable keys. You can try this out using spaces-cli set-file <space> <filename>.

Lifeline

When your space uses a lot of storage and/or you've had it for a while, you may need to extend its life using a LifelineTx. If you don't, your space will eventually become inaccessible and all data stored within it will be deleted by the SpacesVM.

Community Space Support

It is not required that you own a space to submit a LifelineTx that extends its life. This enables the community to support useful spaces with their SPC.

Resolve

When you want to view data stored in SpacesVM, you call Resolve on the value path: <space>/<key>. If you stored a file at a particular path, use this command to retrieve it: spaces-cli resolve-file <path> <destination filepath>.

Transfer

If you want to share some of your SPC with your friends, you can use a TransferTx to send to any EVM-style address.

Move

If you want to share a space with a friend, you can use a MoveTx to transfer it to any EVM-style address.

Space Rewards

50% of the fees spent on each transaction are sent to a random space owner (as long as the randomly selected recipient is not the creator of the transaction).

One could modify the SpacesVM to instead send rewards to a beneficiary chosen by whoever produces a block.

Fees

All interactions with the SpacesVM require the payment of fees (denominated in SPC). The VM Genesis includes support for allocating one-off SPC to different EVM-style addresses and to allocating SPC to an airdrop list.

Nearly all fee-related params can be tuned by the SpacesVM deployer.

Running the VM

To build the VM (and spaces-cli), run ./scripts/build.sh.

Joining the Spaces Demo

If you'd like to validate the Spaces Subnet Demo on Fuji, please follow the following steps:

You can find the genesis used for the Spaces Demo in networks/42/*.

Download and Build SpacesVM

git clone https://github.com/ava-labs/spacesvm.git;
cd spacesvm;
./scripts/build.sh

Running the above commands will generate a binary and save it at ~/spacesvm/build/sqja3uK17MJxfC7AN8nGadBw9JK5BcrsNwNynsqP5Gih8M5Bm.

Move Binary

Once the SpacesVM binary is built, you'll need to move it to AvalancheGo's plugin directory (within the --build-dir) so it can be run by your node. When building from source, this defaults to ~/avalanchego/build/plugins. This build directory is structured as:

build-dir
|_avalanchego
    |_plugins
      |_evm

To put the SpacesVM binary in the right place, run the following command (assuming the avalanchego and spacesvm repos are in the same folder):

mv ./spacesvm/build/sqja3uK17MJxfC7AN8nGadBw9JK5BcrsNwNynsqP5Gih8M5Bm ./avalanchego/build/plugins;

Add Subnet to Whitelist

Next, you'll need to provide the whitelisted-subnets argument by modifying your config file or providing an argument on startup (which tells your node to connect to the Spaces Subnet Demo). Ai42MkKqk8yjXFCpoHXw7rdTWSHiKEMqh5h8gbxwjgkCUfkrk is the subnet id for Spaces Subnet.

Example Config File:

{
  "network-id":"fuji",
  "health-check-frequency":"2s",
  "log-display-level":"INFO",
  "log-level":"INFO",
  "whitelisted-subnets":"Ai42MkKqk8yjXFCpoHXw7rdTWSHiKEMqh5h8gbxwjgkCUfkrk"
}

Example Node Args:

--whitelisted-subnets=Ai42MkKqk8yjXFCpoHXw7rdTWSHiKEMqh5h8gbxwjgkCUfkrk --network-id=fuji

Restart Node

Once you've performed the following steps, you'll need to restart your AvalancheGo node for the changes to take effect.

If you completed the steps successfully, you'll see the node print out:

Become a Fuji Validator

Once your node is up and running with the SpacesVM, you'll need to become a Fuji Validator. This is the exact same flow as Mainnet except you only need to stake 1 AVAX instead of 2000 AVAX.

Recall, only validators on the Primary Network (in this case Fuji) can become validators of subnets.

Submit a Validator Request

Once you've completed the above steps and your node is fully bootstrapped, submit a Spaces Demo Validator Request to be considered as a validator (everyone will be approved).

The Spaces Subnet Demo is a Permissioned Subnet and requires explicit approval from the creator to validate. In the near future, it will be possible to create permissionless subnets that anyone can join.

If you have any questions, reach out to @_patrickogrady on Twitter!

Running a local network

scripts/run.sh automatically installs avalanchego, sets up a local network, and creates a spacesvm genesis file. To build and run E2E tests, you need to set the variable E2E before it: E2E=true ./scripts/run.sh 1.7.11

See tests/e2e to see how it's set up and how its client requests are made.

# to startup a local cluster (good for development)

./scripts/run.sh 1.7.11

Deploying Your Own Network

Anyone can deploy their own instance of the SpacesVM as a subnet on Avalanche. All you need to do is compile it, create a genesis, and send a few txs to the P-Chain.

You can do this by following the subnet tutorial or by using the subnet-cli.
