What becomes possible with FVM?

Perpetual Storage Deals

“Permanent” storage + real proofs of data persistence

We know that many data storage clients don’t want to just store data for a year or two - they want to store ONCE and leave the long-term persistence problem to the network itself! Filecoin has always put control for data storage replication and longevity in the hands of users - but FVM unlocks new opportunities.
With FVM, perpetual storage becomes a simple smart contract on top of Filecoin’s verifiable storage proofs. Just provision a wallet with a storage endowment, and set repair bots to monitor your data CIDs and storage deals, always making new storage deals with qualifying storage providers whenever Filecoin’s daily proofs of storage indicate a copy needs replication
This gives you the same long-term permanence that other blockchains claim, while ALSO benefiting from Filecoin’s verifiable storage proofs,
which ensure that YOUR data is being stored and replicated correctly by the network - raising the bar for responsible data preservation everywhere!

Data DAOs

1. Collectively curate useful data

2. Govern + sell data access

3. Shared treasury for data preservation + growth

Hypervisors and virtual machines

Unix kernel

Actor model

20 of 38

Built to support multiple runtimes�EVM, Wasm (passthrough), SES, LLVM IR, BPF, etc.

Foreign addressing support�via delegated addressing

Abstract accounts�supporting foreign signature schemes, and more

IPLD-native�all data (params, state) is IPLD

Low level system calls�Unix inspired architecture to interact with the env

Built-in resource metering�for gas accounting

Based on WebAssembly�using wasmtime under the hood

So this is what the FVM looks like.
It is based on WebAssembly, using wasmtime under the hood in its reference implementation. You can think of Wasm running at the hypervisor layer.
It can power multiple runtimes, like EVM, Secure EcmaScript, and more through the virtualization model I just described.
Each actor runs in isolation, and can escape its sandbox through syscalls, very much inspired by the Linux model.
All data managed and exchanged is IPLD data, in other words, content addressed linked data.
It supports foreign addressing and foreign signatures schemes.
It performs gas accounting and execution halt by instrumenting the Wasm bytecode.

IPVM: we expect that many of these ideas will make it into the IPVM project, led by Fission, which is establishing a more generalised content-addressed compute environment for a variety of workloads, not just on-chain state transitions.

Libraries to interact with built-in actors�Querying an operating on the storage market, miner actors, verified registry for FIL+ automation, and more.

Filecoin data types�Sectors, deals, partitions, deadlines, and more.

Invoking system features�such as randomness, cryptographic functions, and more.

OpenZeppelin-like utilities specific to Filecoin�For convenience.

Status: prototyping

The reason why devs want to deploy on Filecoin is to interact with its powerful storage system, storage market, storage provider lifecycle, and more.
Solidity is the most used web3 smart contract language, and we want to make it easy for contracts to interact with the Filecoin environment.
For this reason, we’re developing a Filecoin Solidity library that serves like a glue between Solidity smart contracts and the Filecoin system.
You don’t need to use it, but it’ll make your life simpler because it’ll allow you to:

easily call to built-in actor from smart contracts.
It will also add convenience utilities and data types, as well as functions to access Filecoin primitives such as randomness and cryptographic functions.

This library is currently being prototype and we expect the final versions to land over the next month.
