Storing Solana History on IPFS/Filecoin - Project Old Faithful with Brian Long

In a groundbreaking development for the Solana ecosystem, Brian Long discusses Project Old Faithful, an initiative set to revolutionize how blockchain data is stored and accessed. This project, born from a collaboration between Solana and Protocol Labs, aims to make the entire history of Solana's blockchain accessible to anyone, anywhere, without gatekeepers. Let's dive into the details of this transformative project and explore its implications for developers, users, and the broader blockchain community.

The Genesis of Project Old Faithful

Project Old Faithful originated from a critical need within the Solana ecosystem. As Brian Long explains, developers new to Solana often face a significant hurdle when trying to set up their own RPC (Remote Procedure Call) nodes. While they can easily spin up an RPC server, they quickly discover that they lack access to the full historical ledger of Solana transactions. This limitation poses a serious challenge to the principles of blockchain transparency and accessibility.

The inception of the project can be traced back to what Long humorously refers to as the "St. Pancras meeting." At London's St. Pancras Station, Linus Kendall, one of the co-founders, and Richard Patel, a renowned engineer from the Fire Dancer team, engaged in a conversation that would lay the foundation for Old Faithful. Their discussion centered around innovative ways to make Solana's archive history available on a large scale, considering the blockchain's substantial data volume.

The Challenge: Solana's Massive Data Volume

One of the primary challenges addressed by Project Old Faithful is the sheer size of Solana's blockchain data. Brian Long reveals a staggering statistic:

"Currently about 250 terabytes right now is what we've got in the old faithful archive now."

This enormous volume of data presents unique challenges for storage and accessibility. Traditional methods of data storage and retrieval are simply not feasible for such a vast amount of information. The project needed to find a solution that could not only store this data but also make it readily accessible to users without requiring them to download the entire dataset.

Enter IPFS and Filecoin

The solution to Solana's data storage and accessibility challenge came in the form of a collaboration with Protocol Labs, the organization behind IPFS (InterPlanetary File System) and Filecoin. This partnership marks a significant milestone in blockchain technology, showcasing how two layer-one protocols can work together synergistically.

IPFS, or the InterPlanetary File System, is a distributed system for storing and accessing files, websites, applications, and data. Filecoin, built on top of IPFS, provides the economic incentives to ensure that data remains stored and accessible over time. By leveraging these technologies, Project Old Faithful found a way to make Solana's entire history available without requiring users to store massive amounts of data locally.

The Technical Brilliance of CAR Files

At the heart of Project Old Faithful's technical implementation is the use of CAR (Content Addressable aRchives) files. This file format, recommended by Richard Patel, is crucial to the project's success. CAR files are particularly well-suited for use with Filecoin and other content-addressable storage systems.

Brian Long explains the advantages of using CAR files:

"We can throw a 500 gigabyte file on a Filecoin. And if you need to pull a transaction out of that 500 gig file, you don't need to download the entire file. You can say, I want to grab only these bytes."

This capability is a game-changer for data retrieval. It allows users to access specific transactions or pieces of data without downloading entire massive files, significantly reducing bandwidth requirements and improving access speeds.

Compatibility with S3 Storage

Another notable feature of the CAR file format is its compatibility with S3 (Simple Storage Service) compatible storage solutions. This compatibility extends the utility of the project beyond just IPFS and Filecoin. As Long points out:

"That same format is also available or works well, I should say, on any S3 compatible storage, because S3 will support an HTTP range request."

This means that the data can be efficiently retrieved from various storage solutions, providing flexibility and redundancy in data access methods.

The Growth of Solana's Blockchain Data

An interesting aspect of the project is the continuous growth of Solana's blockchain data. Brian Long mentions:

"It grows by 500 gig every two days."

This rapid growth underscores the need for a scalable and efficient storage solution. Project Old Faithful's approach ensures that as the blockchain continues to expand, the data remains accessible without placing an undue burden on individual users or developers.

Democratizing Access to Blockchain Data

One of the most significant achievements of Project Old Faithful is its democratization of access to Solana's blockchain data. Previously, access to the full history was limited to a select few entities that maintained replicas of the data in Google Bigtable. Long describes the previous situation:

"There's only-- I don't know if there's five or six people that have instances or replicas that we're all maintaining independently. And that means that if you want to get the history, you have to go through a gatekeeper."

By making the entire history available through IPFS and Filecoin, Old Faithful removes these gatekeepers. This change aligns perfectly with the ethos of blockchain technology, which emphasizes decentralization and open access to information.

Implications for Developers

The impact of Project Old Faithful on developers in the Solana ecosystem cannot be overstated. With this new infrastructure in place, developers can now:

1. Spin up their own RPC nodes with full historical data access.
2. Perform deep historical analyses of the Solana blockchain.
3. Build more robust and feature-rich applications that require historical data.
4. Verify and audit transactions independently, enhancing trust in the ecosystem.

This level of access and capability was previously impossible or prohibitively expensive for most developers. Now, it's within reach of anyone with an internet connection.

The Challenge of Index Files

While Project Old Faithful solves many problems, it's not without its challenges. One significant hurdle is the size of the index files. Brian Long notes:

"On the 250 terabytes right now, there's just over 50 terabytes of indexes."

These large index files mean that while the data is accessible, setting up a full node with complete indexing capabilities still requires substantial storage resources. This aspect of the project highlights the ongoing challenges in blockchain data management and the need for continued innovation in this space.

The Importance of Data Availability vs. Data Delivery

An important distinction made by Brian Long is between data availability and data delivery. Project Old Faithful focuses primarily on data availability - ensuring that the data exists and is accessible. As Long explains:

"We're really focused on the data availability layer, but not the data delivery layer."

This focus means that while the project ensures the data is there and can be accessed, it doesn't necessarily optimize for the fastest possible delivery speeds. However, the flexibility of the system allows for various optimizations at the delivery layer, depending on specific use cases and requirements.

Flexibility in Data Storage and Retrieval

One of the strengths of Project Old Faithful's approach is its flexibility. The use of CAR files and compatibility with various storage solutions means that users have options in how they store and access the data. Long explains:

"If somebody wants to download it from Filecoin and put it into a nearby S3 storage, they can do that. If they have a really big data center with petabytes of storage, then of course, they could even bring it in local and still access it the same way."

This flexibility ensures that the project can adapt to various use cases and infrastructure setups, making it a robust solution for a wide range of users and applications.

Impact on State Compression

The conversation touches on an interesting implication of Project Old Faithful for state compression in Solana. State compression is a technique used to reduce the amount of data stored on-chain, but it comes with challenges in terms of data accessibility. As one of the hosts points out:

"One of the challenges with state compression right now is that if you aren't indexing compression events as they're happening, you will fairly quickly lose access to those transaction logs, which is where the data actually lives."

Project Old Faithful could potentially address this issue by ensuring that all historical data, including compressed state data, remains accessible. This capability could be crucial for developers working with compressed NFTs or other state compression applications.

Enhancing Blockchain Transparency and Verifiability

One of the core principles of blockchain technology is transparency and verifiability. Project Old Faithful significantly enhances these aspects for Solana. By making the entire history of the blockchain easily accessible, it allows for independent verification of transactions and state changes. As one of the hosts notes:

"Now there's multiple entry points for confirming this or verifying the accuracy and validity of data, which is really awesome."

This capability is crucial for maintaining trust in the ecosystem and allows for more robust auditing and analysis of blockchain activities.

Collaboration Between Layer-1 Protocols

The collaboration between Solana and Protocol Labs (through IPFS and Filecoin) represents a significant development in the blockchain space. As Brian Long points out:

"Now we've got two layer ones that are working together and collaborating in a very positive and synergistic way."

This partnership demonstrates the potential for cross-chain collaborations to solve complex problems in the blockchain ecosystem. It sets a precedent for how different blockchain projects can work together to enhance the overall capabilities and user experience of decentralized technologies.

The Future of Blockchain Data Storage
