Introducing the Access Control Trie (ACT) in Swarm

by Nóra Kuklis | Sep 16, 2024 | Decentralised Data, Access Control Trie

by András Arányi

The Access Control Trie (ACT) is an essential feature designed to manage access control in Swarm’s decentralized storage infrastructure. It enables publishers to grant or revoke access to specific content at the chunk level using encrypted session keys. This guide will walk you through the key concepts and practical aspects of using ACT to protect your data in Swarm.

If you’re a content publisher and looking for a way to share data but maintain full control and privacy, you might find that the below concept of a fully fledged access control mechanism covers all your needs.

Content Publishers

⚠️ TLDR: Publishers can control access to their data by encrypting access keys for each viewer and adding/removing them from the ACT lookup table. ⚠️

As a publisher, you have full control over who can view your content. Using ACT, you can upload your data and grant access to specific grantees (viewers) by referring to their Swarm node wallets’ public keys. Additionally, you can revoke access at any time, ensuring that only authorized viewers have the ability to access your data.

What makes ACT unique is that, as opposed to other solutions which only encrypt data, ACT ensures that only the intended viewers will have access to the data. Everyone else is blocked, even from discovering an encrypted version of it. This significantly increases the privacy and security of your content, preventing unauthorized users from knowing the data even exists.

How to manage access:

Upload your content to Swarm as you normally would, but with ACT request headers included.
Assign access rights by adding the grantee’s public key to the ACT.
If needed, revoke access by removing the grantee from the ACT.

Keep in mind: Publishers can control the latest version of content that grantees are able to access. If you update your content, viewers might still have access to an older version if they were granted access to that earlier version before.

You can learn more about how to manage access using tools like swarm-cli by following the tutorial in the Swarm documentation. These features are also fully supported by the Bee API (starting from version 7.0+), enabling any application to interact with them directly.

Grantees (Content Viewers)

⚠️ TLDR: Grantees can access the specific version of content that the publisher has granted access to, but may lose access to future versions if revoked. ⚠️

As a grantee, your ability to view the content is based on the public key of your Swarm node’s wallet and depends on the permission granted by the publisher. The process for gaining access is simple and secure, thanks to ACT’s encryption mechanisms.

How it works:

Your Swarm node wallet’s public key is used as a session key, which is then used to create two additional keys:
- A lookup key to find your entry in the ACT lookup table.
- An access key decryption key, allowing you to decrypt the content access key specifically encrypted for you.

This ensures that only you can decrypt the content, and you can retrieve the version of the content you have (or have had) permission for.

How ACT Manages Grantee Access

ACT employs a sophisticated mechanism to manage grantee access using public-key cryptography and secure key derivation. At the heart of this system is the ACT lookup table, a key-value store that securely links each grantee’s Swarm node wallet’s public key to an encrypted access key. Here’s a breakdown of how it works:

Session Key:
Each grantee’s Swarm node’s public and private key pair serves as their unique session key. This session key is crucial because it forms the basis for all further encryption steps related to the grantee’s access.
Key Derivation via Diffie-Hellman:
Using Diffie-Hellman key derivation, the session key is used to derive two important keys:
- Lookup Key: This key is used to identify the specific entry for a grantee in the ACT lookup table.
- Access Key Decryption Key: This key is used to decrypt the access key, which in turn allows the grantee to unlock the protected content.
Encrypted Access Keys:
The content access key is encrypted specifically for each grantee using their derived decryption key. This ensures that only the intended grantee can decrypt the access key and thus view the content. This per-grantee encryption adds a layer of security, preventing unauthorized access even if someone else obtains the encrypted data.
ACT Lookup Table:
The lookup table itself is implemented as a key-value store within a Swarm manifest. Each grantee’s public key maps to an encrypted access key, ensuring that only authorized users with the correct session and decryption keys can retrieve the access key and, subsequently, the content. This table allows publishers to manage access dynamically, adding or removing grantees as needed without compromising the security of the stored content.
Adding and Removing Grantees:
Publishers have the flexibility to dynamically add or remove grantees from the lookup table. When a grantee is added, their public key and the corresponding encrypted access key are stored in the lookup table.

Version Control and Historical Access:
The ACT maintains a version history, which includes timestamps for each version of the access control list. If a grantee’s access is revoked for new versions of the content, they can still access older versions to which they had been granted permission, based on the relevant timestamps.

Encryption and Security in ACT

⚠️ TLDR: Every element in the ACT process is encrypted, ensuring complete security of content and access control. ⚠️

As demonstrated earlier, encryption is central to how ACT is implemented. Every component, from the grantee list to the content access keys, is encrypted using strong cryptographic methods. This ensures that only authorized users can access your data, and any tampering or unauthorized access is effectively prevented.

Here’s how encryption is applied:

Grantee List Encryption:
The list of grantees is encrypted using the publisher’s lookup key, ensuring that unauthorized users cannot even detect the existence of the grantee list. This adds another layer of privacy, as only the publisher and authorized grantees are aware of who has access.
Access Key Encryption:
Each grantee’s access key is individually encrypted using their specific decryption key derived through the Diffie-Hellman process. This ensures that only the intended grantee can decrypt the access key and gain access to the protected content.
Historical Version Encryption:
All versions of the ACT, including older ones, are protected by encryption. This means that even if a grantee’s access is revoked, the historical data they had access to remains encrypted and secure.

Content Encryption:
Finally, the actual content itself is encrypted at the chunk level. Only those who possess the correct access key (which is encrypted for each grantee) can decrypt and retrieve the content.

Key Takeaways

Publishers: Maintain control over your data and manage grantee access with fine-grained control using ACT. You can easily add or remove access rights and ensure your data is always protected by encryption.
Grantees: Access specific versions of content securely, knowing that only you have the ability to decrypt the content you’ve been granted access to.

For anyone operating in the Swarm ecosystem, the Access Control Trie (ACT) represents a critical advancement in decentralized content management, offering robust security while maintaining flexibility in access control.

Optimized chunk production for compact usage of postage buckets: A Swarm Hack Week success

by Nóra Kuklis | Jul 2, 2024 | Uncategorized

During the recent Swarm Hack Week, the Solar Punk team hosted a hackathon where Mirko from Etherna developed a project aimed at addressing the inefficiencies in postage batch consumption in Swarm’s data storage. Currently, storing data in Swarm requires purchasing postage batches with a depth much larger than necessary, leading to significant inefficiencies and increased costs. The project focused on optimizing this process to make the nominal space in postage batches truly usable.

Steps of development

Using Bee.Net, an open-source C# library, he introduced a “compaction level” ranging from 0 to 100. This compaction level controls the effort put into compacting chunks within buckets. At level 0, there is no effect on chunk compaction, while at level 100, the compaction is maximized. The compaction level sets a trigger limit on bucket collisions, prompting the system to mine a better chunk hash when collisions occur. To enhance precision at higher compaction levels, he implemented this using a parabolic function.

Mirko added a custom byte in front of each data chunk’s payload to enable the mining of different chunk hashes, resulting in data chunks containing 4095 bytes of actual information instead of the original 4096 bytes. To interpret these optimized chunks, the reader simply drops the first byte of each data chunk. This approach ensures that the optimization can be executed solely on the client side, though it would be more efficient if handled server-side.

The key advantages of this approach include making nominal space in postage batches usable, reducing postage batch costs, and not requiring additional resources for storing decryption keys. The algorithm works even if not all chunks within the postage batch are optimized, and different files can utilize different compaction settings, enhancing flexibility.

If you would like to take a closer look on the project’s code, you can reach it on the following link: https://github.com/Etherna/bee-net/tree/feature/BNET-99-swarm-hackathon-2024

Future work

Future work will focus on developing a deterministic method for hash production to enhance consistency, refining the trigger level formula for better performance at lower levels, and investigating solutions for the potential impact of unoptimized chunks on lower depths due to the birthday paradox.

This Swarm Hack Week project has significantly advanced the optimization of Swarm’s storage. By implementing a compaction level and optimizing data chunks, he has made Swarm’s storage more efficient and cost-effective. This collaborative innovation exemplifies the potential for future improvements in decentralized data storage. Stay tuned for more updates as we continue to enhance Swarm’s capabilities!

by Barbara | Feb 6, 2024 | Decentralised Data, News

The “OnlyFake” scandal, exposing the ease of bypassing KYC checks with forged IDs, throws a spotlight on the vulnerabilities of centralised verification systems in crypto. But fear not, for decentralisation and Swarm, a leading decentralised data storage and distribution technology, might hold the key to a more secure and empowering future.

Centralised KYC: A Honeycomb for Hackers and Fraudsters

Storing user data on centralised servers creates a honeypot for malicious actors. Deepfakes become potent weapons, exploiting weak verification processes to jeopardise financial security and erode trust. Opaque verifications further exacerbate the issue, leaving users with little control over their data and fostering privacy concerns.

Swarm & Decentralization: Empowering Users, Fortifying Security

Decentralisation offers a paradigm shift. By storing user data on blockchains like Swarm, a distributed and tamper-proof ledger, we eliminate central points of attack. Users regain control through self-sovereign identities, fostering trust and transparency. But how do we verify attributes without exposing sensitive information?

Zero-Knowledge Proofs: Verifying Without Revealing

Zero-knowledge proofs (ZKPs) act as cryptographic shields. They allow individuals to prove they possess certain characteristics (e.g., being above 18) without revealing any underlying data. This guarantees privacy while maintaining the integrity of verification.

A Glimpse into the Future: Secure & Empowering Crypto Identity Management with Swarm

Imagine a world where:

Swarm-powered decentralised storage eliminates honeypots, making data breaches a distant memory.
ZKPs render deep fakes useless by focusing on attribute verification, not identities.
Users hold the reins of their data, fostering trust and transparency within the ecosystem.

Here’s how Swarm and ZKPs could work together:

Store ID data on Swarm: Users upload their encrypted ID documents to the decentralised Swarm network, ensuring data privacy and distribution across multiple nodes.
Zero-knowledge verification: When required, users leverage ZKPs to prove they possess necessary attributes (e.g., age) without revealing the entire document.
Empowered control: Users maintain complete control over their data, deciding who can access specific attributes and revoking access as needed.

The “OnlyFake” incident serves as a stark reminder of the need for change. By embracing Swarm-powered decentralisation and ZKPs, we can create a crypto space where security, privacy, and user empowerment reign supreme.

The question now lies with you: Are you ready to join the movement towards a more secure and empowering crypto future?

Understanding Erasure Coding in Distributed Systems: A Guide to Swarm’s Innovative Approach

by Barbara | Feb 1, 2024 | Decentralised Data

Introduction to Data Storage in Distributed Systems

In our increasingly digital world, the importance of effective and secure data storage cannot be overstated. Distributed systems, such as cloud storage networks, represent a significant advancement in this area. These systems distribute data across multiple locations, ensuring accessibility and resilience against failures or data losses. However, this distributed nature also introduces unique challenges in terms of data storage and retrieval. For instance, ensuring data integrity and availability across different nodes in a network becomes more complex. Understanding these challenges is crucial for appreciating the innovative solutions like Swarm’s erasure coding, which are designed to address these specific issues.

Overview of Erasure Coding in Swarm

Imagine you have a jigsaw puzzle, and even if a few pieces are missing, you’re still able to recognise the picture. This analogy aptly describes the principle behind erasure coding, a method used for protecting data in distributed systems like Swarm. In Swarm’s context, erasure coding is not just a safety net for missing data; it’s a strategic approach to ensure data is both secure and optimally stored. This coding technique involves dividing data into chunks, then adding additional ‘parity’ chunks. These extra chunks allow the system to reconstruct the original data even if some chunks are lost or corrupted, much like how you can still make out a picture with a few missing puzzle pieces.

Comparison with Traditional Methods

Traditional data storage methods often rely on redundancy—storing multiple copies of data across different locations. While this approach is straightforward, it’s not the most efficient, especially in terms of storage space and resources. In contrast, erasure coding, as used in systems like Swarm, presents a more sophisticated solution. It strikes an optimal balance between data availability and storage efficiency. By storing additional parity information rather than complete data copies, erasure coding provides a reliable means of data recovery with less overall storage requirement. This efficiency makes it particularly suitable for distributed systems, where resource optimization is key.

Deep Dive into Swarm’s Erasure Coding

Swarm’s implementation of erasure coding through Reed-Solomon coding is a masterclass in data protection. This method, at its core, involves breaking down data into manageable chunks, followed by the creation of additional parity chunks. These extra chunks act as a safety mechanism, allowing for the reconstruction of the original data, should any part be lost or corrupted. It’s a method that mirrors the intricacies of a well-crafted puzzle, where each piece, even if minor, plays a crucial role in the bigger picture. This intricate process not only ensures data integrity but also bolsters the system’s ability to recover from unforeseen data losses.

Real-World Applications in Swarm

In practical scenarios, Swarm’s use of erasure coding is a game-changer, especially in maintaining data integrity and availability. In real-world applications, such as cloud storage services, this translates to an unparalleled reliability for users. Whether it’s safeguarding critical business documents or preserving cherished family photos, Swarm’s system ensures that users’ data remains intact and retrievable, even in the face of partial data losses. This level of reliability and security is what makes Swarm stand out in the crowded field of data storage solutions.

Benefits Specific to Swarm’s Approach

Swarm’s unique approach to erasure coding brings with it a suite of advantages. The enhanced data security that comes from this method is the most prominent, providing a robust shield against data loss. Moreover, the system’s efficiency in data storage is noteworthy; by reducing the need for redundant data copies, it significantly cuts down on storage requirements. This efficiency is not just about saving space – it’s also about optimising resources and reducing costs, making it a highly cost-effective solution for large-scale data storage needs.

Technical Challenges and Solutions

The implementation of erasure coding in Swarm, while beneficial, is not without its complexities. Managing the intricate balance between data accessibility, integrity, and storage efficiency presents a significant challenge. However, Swarm’s sophisticated coding techniques and network management strategies have been meticulously designed to address these issues. By continually refining these strategies, Swarm ensures a seamless and reliable user experience, maintaining its status as a leader in distributed data storage.

Conclusion

Erasure coding in distributed systems like Swarm marks a significant milestone in digital data storage and protection. In an era where data’s value is ever-growing, the importance of technologies like erasure coding cannot be understated – they are essential for the reliability and security of our digital world.

Zero-Knowledge Rollups and Ethereum Scalability: The Future of Interoperability

by Barbara | Jan 23, 2024 | News

In recent weeks, the world of blockchain technology has witnessed a surge in the launch of projects centered around zero-knowledge proofs. Notable offerings include Polygon’s zkEVM, Matter Lab’s zkSync Era on the Ethereum mainnet, and ConsenSys’ Linea zkEVM on the testnet. These projects share a common goal: to enhance Ethereum’s scalability by harnessing the power of zero-knowledge proofs. In this article, we delve into this exciting development and explore the potential future of interoperability in the realm of zero-knowledge rollups.

Zero-Knowledge Proofs: The Foundation

Zero-knowledge proofs are cryptographic techniques that allow one party to prove they possess specific knowledge without revealing the actual knowledge itself. In the context of blockchain technology, these proofs enable Ethereum to scale efficiently. Rollups, a key concept in this context, offload the computation for thousands of transactions from the main Ethereum blockchain, providing a tiny cryptographic proof that validates the correct execution of these transactions.

Competing Rollups or Collaborative Harmony?

As these zero-knowledge rollup projects gain momentum, a pressing question arises: Is it a winner-takes-all competition among them, or can they coexist harmoniously, working together seamlessly? Anthony Rose, head of engineering for zkSync, envisions a future where multiple rollups can collaborate, making it irrelevant for users to choose a specific one. In his view, the rollups will become an integral part of the blockchain infrastructure, much like how users of platforms like Snapchat or Facebook don’t need to understand the technical intricacies of the internet.

Interoperability: The Bridge to the Future

Transitioning from a landscape of competing rollups to an ecosystem of interoperable and composable zero-knowledge solutions is a significant challenge. Fortunately, the community is already contemplating this transition, and all the zero-knowledge projects mentioned are working on plans to achieve interoperability to varying degrees. The extent of this interoperability, however, largely depends on the development of standards and protocols.

Ethereum Scalability: Current Status

Currently, Ethereum’s scalability faces practical limitations due to data availability on the network. Despite various solutions claiming theoretical scalability figures in the tens of thousands of transactions per second (TPS), the reality is different. Ethereum and its scaling solutions collectively process around 25 transactions per second, with Ethereum itself averaging about 12 TPS over the past month. Arbitrum One, Optimism, and zkSync offer TPS in the range of 1.6 to 7.2.

The Road to Interoperability

Interoperability between rollups is crucial to prevent users from being confined to isolated ecosystems. For instance, Optimistic Rollup users experience a one-week waiting period for fund withdrawals, limiting their ability to interact with other ecosystems. Achieving interoperability is technically possible, but its practical implementation depends on factors such as the financial viability of frequently putting proofs on Ethereum, which currently results in delays of 10 to 20 minutes between transactions.

Interoperability vs. Composability

It’s important to distinguish between “interoperability” and “composability.” While these terms are often used interchangeably, they have distinct meanings. Interoperability involves the seamless movement of funds between different layer-2 solutions. Composability takes it a step further, enabling transactions that involve operations across multiple rollups. Achieving composability may require the development of new standards and protocols.

The Role of MetaMask Snaps

MetaMask, a popular browser wallet, offers another avenue for achieving interoperability. They are developing Snaps, which are crowdsourced wallet extensions that extend MetaMask’s capabilities. Snaps could facilitate communication between different ZK-rollups, allowing them to interact with each other effectively.

Composability: The Future Frontier

Composability entails transactions involving operations on different rollups in a more real-time manner. This requires the development of new standards and protocols, and the sooner this happens, the better the user experience will be. With synchronous composability, transactions can be seamlessly executed across different off-chain systems, offering users an optimal liquidity experience.

The Potential of Optimism’s Superchain

Optimism introduces the concept of a “Superchain” that aims to integrate various layer-2 solutions into a single interoperable and composable system. Shared sequencing and the separation of proving and execution are key aspects of this concept, allowing cross-chain operations like flash loans to occur efficiently.

Direct Connection between ZK-Rollups

Some experts believe that ZK-rollups can connect directly with each other, as long as they can verify each other’s proofs. Smart contracts can be written to interpret incompatible proofs used by different rollups, enabling direct communication. This approach simplifies interoperability, especially when rollups share a common codebase.

Towards an Interoperable and Composable Future

In summary, the future of Ethereum scalability is expected to revolve around interoperability and composability among various zero-knowledge rollup solutions. These advancements will be driven by the development of standards, protocols, and collaborative efforts among the blockchain community. As these systems mature, users and developers alike will benefit from a more interconnected and efficient Ethereum ecosystem.

Understanding Decentralised Data Storage Costs on Ethereum Swarm

by Barbara | Dec 18, 2023 | Decentralised Data

In the dynamic world of blockchain technology, Ethereum Swarm stands out as a cornerstone for decentralized data storage and communication. It’s crucial for users and developers in the Ethereum ecosystem to understand the intricacies of storage costs on this platform. This article delves deeper into the various factors affecting these costs, including network size, data size, and the critical role of BZZ tokens in pricing.

What is Ethereum Swarm

Ethereum Swarm is not just a decentralized storage system; it’s an extension of Ethereum‘s vision to build a comprehensive, decentralized internet. It enables data to be stored and distributed across a network of nodes, reducing reliance on centralized servers and mitigating risks like data loss or censorship. Swarm is designed to seamlessly store Ethereum’s dApp data, smart contracts, and user data, ensuring high availability and resistance to outages.

Factors Influencing Storage Costs

Network Size: The cost of data storage on Swarm is significantly influenced by the network’s size. A larger network means more nodes are available to store data, leading to increased redundancy and potentially lower costs due to economies of scale. In contrast, a smaller network might have higher costs due to increased demand for the limited storage space available.

Data Size: The volume of data being stored directly impacts the cost. Larger files require more space and network resources, naturally incurring higher costs. Smaller data sets, however, are less resource-intensive, making them more economical to store.

The Role of BZZ Tokens

BZZ tokens, Swarm’s native cryptocurrency, are fundamental to its operational model. These tokens facilitate transactions within the Swarm network, serving as a form of payment for storage services. Users pay for storage in BZZ, while node operators earn BZZ by providing storage space. This creates a decentralized market for storage, where prices are governed by supply and demand.

The Pricing Mechanism

Swarm’s pricing model is dynamic, adjusting to real-time conditions in the network. Storage costs are calculated based on several factors, including the amount of data, network congestion, and the availability of nodes. This ensures that the pricing is fair, competitive, and reflective of the network’s current state.

Swarm’s Postage Stamps Mechanism

An integral part of understanding data storage in Swarm is its unique “postage stamp” system. This mechanism is crucial for the functioning of the Swarm network and influences storage costs:

Concept of Postage Stamps: In Swarm, users must purchase “postage stamps” to upload and store data. These stamps are essentially proof of payment attached to the data being stored, ensuring that the data remains in the network for a predetermined amount of time.

Functioning: When a user wants to store data, they buy a postage stamp using BZZ tokens. The price of the stamp depends on the size of the data and the desired storage duration. The data with a valid postage stamp is then accepted and stored by the nodes in the network.

Impact on Storage Costs: The cost of postage stamps adds an additional layer to the overall storage costs on Swarm. It’s a pay-as-you-go model where the more data you store and the longer you want it stored, the more postage stamps you need to purchase.

Understanding Swarm’s Cost Per Gigabyte Per Year

Calculating the cost of storing data, such as a gigabyte for a year on Ethereum Swarm, requires an understanding of several dynamic factors:

Market Value of BZZ: Since storage costs are paid in BZZ tokens, the market value of BZZ significantly impacts the cost. As the value fluctuates, so does the cost of storage.

Network Demand and Supply: Costs vary depending on the balance between available storage space and the demand for storage. Higher demand or limited supply can drive up costs.

Data Redundancy and Replication: Swarm ensures data redundancy for reliability, which might affect the cost as more copies of the data are stored across different nodes.

Given these variables, providing an exact figure for the cost per gigabyte per year can be challenging. However, for illustrative purposes, let’s assume a scenario:

Assume that 1 BZZ equals X USD, – you can check the up to date prices here – and the current rate for storing 1 GB of data for a month is Y BZZ – check the up to date Swarm storage price here. Therefore, the cost to store 1 GB of data for a year would be (Y * 12) * X USD. At the time of writing, based on this calculation you’d pay $1.561 for storing one GB of data for a year on Swarm. It’s important to regularly check the latest rates and BZZ value for the most accurate cost estimation.

Comparisons with Other Storage Solutions

When compared to other decentralized storage systems like IPFS (InterPlanetary File System) and Filecoin, Swarm offers a distinct approach. While IPFS focuses on peer-to-peer file sharing and content addressing, Swarm provides more integrated storage solutions specifically designed for the Ethereum ecosystem. Filecoin, with its unique proof-of-storage model, represents another alternative, highlighting the diversity in decentralized storage solutions.

Future Outlook and Scalability

The future of Swarm is closely tied to the broader development of the Ethereum ecosystem. As Ethereum evolves, so too will Swarm, potentially leading to more efficient storage solutions and cost reductions. Key to this evolution will be improvements in scalability and network efficiency, which are expected to impact storage costs positively.

Conclusion

Grasping the nuances of storage costs on Ethereum Swarm is vital for anyone engaged in the Ethereum ecosystem. The cost is influenced by factors like network size, data volume, and the economic model governing BZZ tokens. As Swarm continues to grow and evolve, staying informed about these developments is crucial for developers and users alike.
