Introducing Slingshot Phase 2

Introducing Slingshot Phase 2

Slingshot is a community competition for storage clients and developers that rewards the storage of real, valuable, and usable data on the Filecoin network. Phase 1 of the Slingshot competition ran for four weeks. In that time, the Filecoin storage client and developer communities passed several important milestones, including:

In this blog post, we are introducing Phase 2 of the Slingshot competition. If you are interested in earning FIL rewards for storing valuable data on the Filecoin network, Slingshot is for you!

Introducing Slingshot Phase 2

Slingshot Phase 2 is a community competition that rewards the storage of valuable data onto the Filecoin network. In Phase 2, we are looking for teams that are excited to preserve public, open-access datasets on the Filecoin network.

Slingshot has the following goals:

How to Participate in Slingshot Phase 2

In this competition, participants are rewarded for storing curated datasets (i.e. public datasets approved for storage in this competition) in well-documented, thoughtful, and reusable ways.

Slingshot Phase 2 is a very different competition from Slingshot Phase 1. If you are participating in Phase 2, please read this section carefully!

To participate in Slingshot Phase 2, you must store one of the curated datasets that are listed on the Slingshot GitHub repo. Once you have made your dataset choice and determined a plan for storing this data, you can register to participate in the competition on the Slingshot website: https://slingshot.filecoin.io. Then, continue storing valuable data to earn more rewards.

To be eligible for rewards in this competition, you must follow the Competition Rules:

If you have questions at any point in the competition, check out:


We are excited to announce that Slingshot Phase 2 will distribute at least 500,000 FIL in rewards! This is in addition to the 50,000 FIL that will be distributed for Slingshot Phase 1.

Storage Rewards

Slingshot reward pools are collaborative and competitive. The more data is stored to the network by Slingshot participants, the more reward pools you will unlock!

Total Data Onboarded by Slingshot Participants Reward Pool Unlocked for this Storage Tier (FIL) Cumulative Reward Pool (FIL)
500TiB (Phase 1) - 50,000
1PiB 50,000 100,000
1.5PiB 25,000 125,000
2PiB 25,000 150,000
2.5PiB 25,000 175,000
3PiB 25,000 200,000
More to be announced

Storage Rewards are distributed every month in which a storage tier has been unlocked. Our plan is to continue this competition for the next several months. We think it would be a lot nicer if we were able to give out rewards on a monthly basis instead of having to wait until the very end of the competition! As a result, we have monthly reward windows that we will use to determine final rewards distribution for the month. All deadlines below are at 1800 UTC.

Reward Deadline: We will take a snapshot of the competition at this point to determine rankings/data stored. If no prize pools have been unlocked by this date, we will not distribute any rewards in this reward period. Material Submission Deadline: This is the deadline to submit additional materials, e.g. CID lists and documentation. Participants will submit this information through the Slingshot website. Judging Period: Community Reviewers will review all projects during this period, and determine valid data stored and final rewards. Winners Announced: Final rewards are determined and winners are announced. Rewards will be distributed within 1-2 weeks after this date and all rewards vest over 6 months from distribution date.

Storage Rewards will be distributed proportionally based on the amount of new valid data that Slingshot participants have stored in the reward window. The amount of valid data might be different than the total data you have stored, after accounting for too many redundant copies, unretrievable data, datasets that don’t match the curated dataset list, poor documentation, if you have lots of unretrievable data, and more. Some teams may be outright disqualified for not following the rules, so make sure you follow the rules please!

Booster Rewards

In addition, we will be offering Booster Prizes in Slingshot Phase 2! If you follow the rules and store more than 50GiB of new data in the reward window, you will receive a 10FIL Booster Prize.

Other prizes may become available over time as well!

Note: All rewards earned will vest linearly over six months from mainnet launch. Additionally, while we don’t expect it, in the unlikely event that Protocol Labs or the Filecoin Foundation determine in their sole discretion that legal or regulatory issues prevent the delivery of any portion of rewards, the rewards may be restructured, postponed, or cancelled.

Thank you!

We are excited to continue the Slingshot competition with familiar Phase 1 participants and new faces alike! Your efforts will greatly contribute to continue to grow the amount of real data stored on humanity’s largest decentralized storage network. Thank you to the Filecoin storage client, developer, and mining communities. Onward to Slingshot Phase 2!
