Today, Filecoin and Hedera Hashgraph are announcing a joint effort to advance the interoperability of Web3. Starting with a USD $200,000 grants program and an initial demo implementation for NFT use cases, the long-term vision is a full range of distributed ledger solutions, including distributed consensus, storage, and smart data applications, that combine the strengths of both networks.
The Hedera public network is a fast, low-cost, and eco-friendly distributed ledger technology (DLT), designed for high-volume usages such as supply chain, verifiable proofs for data, payments, advertising, tokenization of assets, and more. The Hedera network is incredibly efficient and lightweight, but it’s not ideal for storing large files or object data due to cost constraints.
This is a decentralized peer-to-peer storage network using IPFS technology, allowing anyone to store and validate data within its network. Currently, hundreds of storage providers worldwide participate in the Filecoin network, offering a combined 8 exabytes of storage capacity.
And that’s where Filecoin and Hedera’s partnership comes into play: Hedera brings highly efficient DLT capabilities, while they offers a robust, flexible large-scale storage layer. Combining both networks provides new possibilities to verify the provenance, ownership, and validity of both transactions and their underlying data.
The Hedera Token Service (HTS) enables the configuration, management, and transfer of native non-fungible tokens (NFTs) on the Hedera platform. Tokens are as fast, fair, and secure, costing less than 1¢ USD to transfer. NFTs can be a unique digital representation of anything from an in-game item to a physical or digital asset.
Hedera Improvement Proposal 10 ( HIP-10) offers an ecosystem standard for NFT metadata. To bolster this new functionality, Filecoin protocol (using the NFT.storage integration) enables decentralized storage of the JSON schema containing those NFT properties and multimedia or localization data.
Combining Hedera and Filecoin delivers a truly decentralized NFT experience. They are acting as a decentralized storage layer for NFTs on the Hedera network ensures a maximum amount of trust for in-game assets, art, music, supply chain, financial applications, and more.
The open-source reference implementation and demo showcase how you can issue NFTs on HTS, then store that data on this using the NFT.storage API: https://github.com/hashgraph/hedera-hts-demo/.
The Starling Framework for Data Integrity is a joint effort developed by the USC Shoah Foundation and Stanford University’s Department of Electrical Engineering. The initiative aims to create a set of tools and principles to be used across non-profit organizations, news outlets, and industry experts to solve challenges regarding the uncertainty of the media we see today and our enduring effort to preserve the truth. Starling leverages multiple decentralized technologies, including Filecoin and Hedera, to store and verify original media assets and their underlying metadata.
While the cost of storage on Filecoin is quite competitive, Filecoin is much more than just storage. By introducing large-scale storage with periodic proofs and bringing storage closer to compute, Filecoin brings a unique building block to the Web3 ecosystem.
- Content Addressable Data — This is a decentralized storage network built on Content Addressable Data at the heart of Web3.
- Verifiable Storage with Proofs — The Filecoin blockchain verifies that all data is continuously stored on the network every 24 hours; proof of this can be bridged to other smart contract systems.
- Decentralized Storage at Scale — This network is onboarding more than 1PiB of storage capacity every hour.
- Flexible Storage Options — A global network of storage providers, each offering different features and local optimizations, allow for maximal composability and emergence.
Many new interactions, applications, and business models can emerge at the intersection of Filecoin and smart contract systems such as Hedera. You can find more information about the business opportunities on Filecoin in this talk.
Filecoin and Hedera are awarding $200,000 in developer grants along two tracks:
- Decentralized Storage SDK for Hedera & Demo Application — We want to make it easy for builders using Filecoin Storage and Hedera Token Service to integrate the two into their applications. This grant will be awarded for an SDK that seamlessly integrates existing Hedera and Filecoin toolchains. It should enable non-fungible tokenization and allow storage of larger files associated with Hedera Token Service tokens (such as digital art, music, JSON metadata, etc.) on the Filecoin network. Filecoin storage may be accessed via tooling or services such as Estuary, Fleek Space Daemon, NFT.storage, or Textile Powergate.
The accompanying demo application must use this SDK to build an open source end-to-end NFT marketplace demo application to 1) Showcase the functionality of the Decentralized Storage SDK and 2) Be used by other developers in the community as a reference architecture. The demo application should include:
- NFTs created on Hedera.
- Multimedia associated with the NFT stored on Filecoin.
- JSON metadata schema associated with those NFTs on Filecoin.
- Accepting HBAR and FIL (at a minimum) for payment of NFTs.
2. Real-world Applications: These grants will be awarded to proposals for real-world applications that utilize both Hedera Token Service (HTS) and Filecoin decentralized storage. Developers can be as creative as they’d like — there are no strict requirements as to the type of application or use case, but it must utilize both Hedera HTS and Filecoin. Filecoin storage may be accessed via tooling or services such as Estuary, Fleek Space Daemon, NFT.storage, or Textile Powergate.
First prize: $50,000; Second prize: $40,000; Third prize: $20,000; Fourth prize: $10,000; Fifth prize: $5,000;]
