Incentivizing Useful Data Storage on Filecoin

Filecoin Plus (Fil+) is a program that makes it easier and more rewarding to store important data on the Filecoin network. Whether it's scientific research, public records, videos, or archives, Fil+ helps make sure the network is filled with content that matters.

Through a form of storage credit called DataCap, Fil+ gives clients access to better storage deals, and rewards storage providers who store this kind of meaningful data.

How It Works

The Filecoin Plus Process

  • 1

    Clients Apply for DataCap

    Organizations or individuals who want to store important data—like open datasets or cultural archives—can request DataCap.

  • 2

    Allocators Review Application

    A group of trusted community members, called Allocators, review each request. If it meets the criteria, they assign DataCap to the client.

  • 3

    Storage Deal

    With DataCap, clients can make deals on better terms. Storage Providers get higher rewards for storing this verified data.

For Clients

Store valuable data with more trust

As a client, Filecoin Plus helps you store important real-world data—like public records, research, or open-source datasets—more effectively. By working with an approved allocator, you can request DataCap, a special resource that signals to storage providers that your data is valuable and trusted. This makes it easier to secure deals and can lead to better pricing and prioritization.

Support the integrity of the network by guiding how DataCap is distributed

Allocators are trusted community members who help decide which clients receive DataCap. This role is central to ensuring that Filecoin is used for storing meaningful, verifiable data rather than spam or low-quality content.

Becoming an allocator involves understanding the program's principles, submitting an application that outlines your background and evaluation approach, and participating in a transparent community review process.

For Storage Providers

Boost your ability to earn block rewards by storing valuable data

For storage providers, Filecoin Plus offers a direct incentive to prioritize verified, high-value data.

When you accept deals backed by DataCap, your Quality Adjusted Power increases—improving your ability to earn block rewards. These deals often come from clients who are working on public-good projects and value long-term reliability.

Frequently Asked Questions

FAQs

What is Filecoin Plus (Fil+)?

Filecoin Plus is a program designed to increase the amount of useful data stored on the Filecoin network. It achieves this by providing verified clients with DataCap tokens, which they can use to make storage deals with storage providers. These deals are considered higher quality and incentivize storage providers to store valuable data.

What is DataCap?

DataCap is a token allocated to verified clients, allowing them to make storage deals with storage providers. These deals are recognized as verified, enhancing the storage provider's reputation and potential rewards. DataCap is a one-time credit and cannot be transferred between addresses. If a client needs more DataCap, they must request additional allocations.

How does Filecoin Plus benefit storage providers?

When storage providers accept deals that utilize DataCap, their Quality Adjusted Power (QAP) increases. This higher QAP boosts their chances of earning block rewards. However, it's important to note that while the probability of earning rewards increases, the actual amount of rewards does not multiply.

How can clients acquire DataCap?

Clients can obtain DataCap by applying through approved allocators. The process typically involves:

  1. Creating a Filecoin wallet.
  2. Choosing an allocator from the list of approved allocators.
  3. Ensuring they meet the allocator's requirements.
  4. Submitting an application for DataCap.
  5. Using the allocated DataCap in storage deals.

Can smart contracts use DataCap?

Yes, smart contracts can acquire and use DataCap similarly to regular clients. To do so, the smart contract's address must be specified when requesting DataCap. It's important to remember that DataCap allocations are tied to specific addresses and cannot be transferred. If a smart contract is redeployed with a new address, a new DataCap allocation is necessary.

What responsibilities do storage providers have when accepting verified deals?

Storage providers accepting verified deals must:

  • Ensure the data is stored securely and reliably.
  • Provide regular proofs of storage to the network.
  • Be prepared to offer data retrieval services to clients.
  • Understand that while the potential rewards are higher, so are the penalties for failing to meet the network's standards.

How does one apply to become an Allocator?

To apply to become a Filecoin Plus Allocator, follow these steps:

  1. Open a Pull Request — Visit the Allocator Governance GitHub page. Create a pull request, name the file "Allocator application", and commit the change as a branch.
  2. Fill Out the Airtable Form — After the pull request is submitted, a GitHub Action will comment with a link to an Airtable form. Fill out the form using your GitHub handle and PR number.
  3. Track the Submission — Once the form is submitted, a corresponding issue will be created for governance review. This issue will also propose adding the new Allocator to the registry JSON file.

For a full list of instructions on how to become an allocator, please visit blog.allocator.tech. We are currently prioritizing new allocators that are developing pathways according to our Request for Allocators (RFA).
