Revolutionizing Language Models: The Emergence of BitNet b1.58

Posted on by Tensae

In recent years, the field of Artificial Intelligence has witnessed an unprecedented surge in the development of Large Language Models (LLMs), fueled by breakthroughs in deep learning architectures and the availability of vast amounts of text data. These models, equipped with powerful Transformer architectures, have demonstrated remarkable proficiency across a plethora of natural language processing tasks, from language translation to sentiment analysis. However, this rapid growth in the size and complexity of LLMs has brought about a host of challenges, chief among them being the staggering energy consumption and memory requirements during both training and inference phases.

To address these challenges, researchers have ventured into various techniques aimed at optimizing the efficiency of LLMs, with a particular focus on post-training quantization. This approach involves reducing the precision of model parameters, thereby curtailing memory and computational demands. While post-training quantization has proven effective to some extent, it remains suboptimal, especially for large-scale LLMs.

In response to this limitation, recent endeavors have explored the realm of 1-bit model architectures, epitomized by BitNet. These models leverage a novel computation paradigm that drastically reduces energy consumption by eschewing floating-point arithmetic in favor of integer operations, particularly beneficial for the matrix multiplication operations inherent in LLMs. BitNet, in its original form, has demonstrated promising results, offering a glimpse into a more energy-efficient future for LLMs.

Building upon the foundation laid by BitNet, researchers have introduced BitNet b1.58, a significant advancement in the realm of 1-bit LLMs. Unlike its predecessors, BitNet b1.58 adopts a ternary parameterization scheme, with model weights constrained to {-1, 0, 1}, thereby achieving a remarkable compression ratio of 1.58 bits per weight. This innovative approach retains all the advantages of the original BitNet while introducing enhanced modeling capabilities, particularly through explicit support for feature filtering.

BitNet b1.58 represents a paradigm shift in LLM architecture, offering a compelling alternative to traditional floating-point models. Notably, it matches the performance of full-precision baselines, even surpassing them in some cases, while simultaneously offering significant reductions in memory footprint and inference latency. Furthermore, its compatibility with popular open-source software ensures seamless integration into existing AI frameworks, facilitating widespread adoption and experimentation within the research community.

Beyond its immediate impact on model performance and efficiency, BitNet b1.58 holds immense promise for a wide range of applications, particularly in resource-constrained environments such as edge and mobile devices. The reduced memory and energy requirements of BitNet b1.58 pave the way for deploying sophisticated language models on devices with limited computational resources, unlocking new possibilities for on-device natural language understanding and generation.

Looking ahead, the development of dedicated hardware optimized for 1-bit LLMs could further accelerate the adoption and proliferation of BitNet b1.58, ushering in a new era of efficient and high-performance AI systems. As the field continues to evolve, BitNet b1.58 stands as a testament to the ingenuity and perseverance of researchers striving to push the boundaries of AI technology.

Runes Protocol: Did It Ruin Bitcoin or Save It?

Posted on by Werner

The future of Bitcoin was at stake last week in two ways: with both the Halving upgrade and the launch of the Runes protocol, a new token standard for issuing fungible tokens directly on the Bitcoin blockchain. The Runes Protocol laid a foundation that will determine the fate of the chain in the decades to come. Activated on 19 or 20 April 2024 on block 840,000, coinciding with the next Bitcoin halving, Runes aims to provide a more efficient and responsible way of creating fungible tokens compared to existing options. Let’s dive into what Runes is all about, who created it, how it works, and what impact it could have on the Bitcoin ecosystem.

What is the Runes Protocol?

The Runes protocol is a new token standard that allows issuers to create fungible tokens on the Bitcoin blockchain in a more efficient way. It can offer users a streamlined method for creating tokens that represent various assets, from stablecoins to governance tokens. Runes positions itself as a robust platform for token creation and management with all the security and immutability of Bitcoin. At least, that’s the official line. For Bitcoin maximalists, Runes and its predecessors Ordinals and BRC-20 are cynical money-grabs that clutter and congest the world’s most important blockchain with its flood of transactions. 

Rodarmor: The Mastermind Behind Runes

Bitcoin developer Casey Rodarmor, well-known as the creator of the Ordinals protocol, proposed Runes in September 2023. Building upon his experience with Ordinals, which opened the door to NFTs on Bitcoin, Rodarmor envisioned Runes as an improved token standard that addresses the limitations of existing solutions like the BRC-20 standard, which he felt required too many steps to complete and wasn’t built in accordance with Bitcoin’s ethos.

Rodarmor designed Runes to be a simple protocol with minimal on-chain footprint and responsible UTXO management. UTXOs, or Unspent Transaction Outputs, represent individual units of Bitcoin value that have not yet been spent. Unlike the BRC-20 standard, which is complex and produces junk UTXOs that congest the Bitcoin network, Runes aims to be more efficient and user-friendly.

Other fungible token protocols on Bitcoin, such as RGB and Taproot Assets, rely on off-chain data storage. Runes distinguishes itself by keeping all token information on-chain using OP_RETURN, a Bitcoin script opcode for storing data. In this way, Runes ensures that asset metadata remains tightly integrated with the base layer.

Under the Hood: How Runes Works

Runes adopts a UTXO-based model that aligns seamlessly with Bitcoin’s design. When a Rune token is created (‘etched’), minted, or transferred, a protocol message called a runestone is generated. Runestones contain all the necessary information, including the token ID, output index, and amount, encoded in an OP_RETURN output.

The token supply of a Rune is stored within a single UTXO, with a maximum supply of approximately 340 undecillion (340 followed by 36 zeros). Each Rune has a divisibility parameter that determines the number of decimal places it can have, up to a maximum of 38.

New Runes are created in a process called etching, where the token’s properties, such as its name, divisibility, symbol, pre-mine amount, and minting terms, are defined. Once etched, the Rune can be minted according to the established terms, with the minter specifying the Rune ID and the desired quantity.

Transferring Runes is accomplished through ‘edicts’ – instructions that define how tokens move from inputs to outputs within a transaction. Edicts support batch transfers, airdrops, and a transfer of all remaining units of a specific Rune ID in a single transaction.

Runes vs. BRC-20 and Ordinals

Runes vs BRC-20

While both Runes and BRC-20 are token-standards built on the Bitcoin blockchain, there are several key differences between the two.

BRC-20 is a meta-protocol that relies on the Ordinals protocol. This means that BRC-20 inherits the complexity of Ordinals, and requires multiple transactions for minting and transferring tokens. In contrast, Runes is a standalone protocol that operates independently of Ordinals, allowing it to create and manage tokens more efficiently.

Another significant advantage of Runes over BRC-20 is its simplified transaction structure. With Runes, minting and transferring tokens can be done in a single transaction, reducing the overall on-chain footprint and minimizing the creation of unnecessary UTXOs. This streamlined approach leads to improved scalability and a more user-friendly experience for token issuers and holders.

Runes vs Ordinals

Although both Runes and Ordinals are protocols built on top of the Bitcoin blockchain, they serve different purposes. Ordinals is primarily focused on creating and managing non-fungible tokens (NFTs) by inscribing data onto individual satoshis. These inscriptions are unique and can represent various types of digital assets, such as artworks, collectibles, or even text.

On the other hand, Runes is designed specifically for fungible tokens, which are interchangeable and divisible. 

The Potential Impact of Runes on Bitcoin

The Runes protocol could have far-reaching implications for the Bitcoin ecosystem, both good and bad. Developers can use Runes to create various types of fungible tokens, potentially attracting a wider user base and expanding Bitcoin’s utility beyond its primary function as a digital currency.

As more projects build on top of Runes, the increased transaction volume could generate additional revenue for miners in the form of transaction fees. This is particularly relevant in light of the halving of the Bitcoin block reward: the added revenue from fees would compensate for one incentive for miners being reduced.

Moreover, Runes could spur innovation within the Bitcoin developer community. Projects like RSIC, a metaprotocol that combines Ordinals with yield-farming, have already emerged in anticipation of Runes’ launch. As developers explore new use-cases and build novel applications on top of Runes, the Bitcoin ecosystem could witness a surge in creativity and experimentation.

However, Runes has also in its short history attracted an avalanche of scam or low-quality projects that offer little to no chances of a return on investment.

The Road Ahead for Runes

Casey Rodarmor’s next plan is to introduce direct trading between users, potentially reducing reliance on centralized exchanges and mitigating issues like Replace-By-Fee (RBF). Additionally, the approval of the OP_CAT Bitcoin Improvement Proposal (BIP) could pave the way for bridging Runes tokens to Layer-2 networks, enhancing scalability and interoperability.

As the Bitcoin community prepares for the launch of Runes, excitement is building around the potential for a new era of token innovation on the world’s most secure and decentralized blockchain. With its focus on simplicity, efficiency, and responsible UTXO management, Runes aims to address the limitations of existing token-standards, and to provide a solid foundation for growth of the Bitcoin ecosystem.

Only time will tell how developers and users will receive and adopt Runes. However, one thing is certain: when Runes is activated at block 840,000, it marks a significant milestone in Bitcoin’s ongoing evolution, opening up new possibilities for token-creation, management, and exchange on the original and most secure blockchain.

The Runes protocol has the potential to bring numerous benefits to the Bitcoin ecosystem –

  • Firstly, Runes can attract a wider user-base by enabling various types of tokens, such as utility tokens, governance tokens, or even stablecoins. This increased diversity of use-cases can draw new users to the Bitcoin network, driving adoption and fostering a more vibrant and inclusive ecosystem.
  • Secondly, the increased activity generated by Runes can make the entire Bitcoin network more sustainable. As more users engage with Runes-based tokens, the demand for block space will increase, leading to higher transaction fees. These fees will draw in more miners to continue securing the network, especially as the block rewards diminish.
  • Lastly, Runes can serve as a catalyst for innovation and experimentation within the Bitcoin ecosystem. By providing a standardized and efficient platform for issuing tokens, Runes can lower the barriers to entry for developers and entrepreneurs who want to build new applications and services on top of Bitcoin. This can lead to a proliferation of novel use-cases, and a more dynamic, resilient, and interesting ecosystem.

Runes provides a platform for token-related activities directly on the Bitcoin blockchain, and can help drive transaction fees, nourishing a sustainable mining ecosystem. Even if some of the tokens created through Runes are shitcoins or memecoins, Rodarmor argues that the fees generated from these activities are still valuable for the network’s security.

Moreover, Rodarmor sees Runes as a way to bring more users and activity to the Bitcoin ecosystem. This increased adoption and engagement can further strengthen the Bitcoin network and its position as the world’s leading cryptocurrency.

How Runes Works

  • Etching is the process of creating a new Rune token and defining its properties. This is done through a special transaction that includes an OP_RETURN output containing the token’s metadata, such as its name, symbol, and any additional attributes.
  • Minting refers to the act of creating new units of a Rune token. The minting process involves specifying the token ID, which is derived from the etching transaction’s block height and transaction index. Minting can be done through an open process, allowing anyone to participate, or it can be restricted based on predefined terms set during the etching process.
  • Transferring Runes involves moving tokens from one UTXO to another. This is accomplished through a transaction that consumes the input UTXOs containing the tokens and creates new output UTXOs with the updated token balances. The transfer process is governed by a set of instructions called ‘edicts’. These edicts specify the token ID, amount, and destination UTXO.
  • In the event of an error during the etching, minting, or transferring process, a ‘cenotaph’ is created. Cenotaphs are runestones with invalid or unrecognized data, and they cause the associated tokens to be burnt. This mechanism encourages responsible UTXO management and helps maintain the integrity of the Runes protocol.

Conclusion

Existing token standards, such as BRC-20, have certain limitations. Every time they are minted or transferred, multiple transactions have to pass through the Bitcoin blockchain, and this leads to increased complexity and network congestion.

In contrast, Runes offers a streamlined approach, allowing you to create and transfer tokens with minimal on-chain footprint and responsible UTXO management. Fewer transactions are needed and Bitcoin’s limited block space is used more optimally. It is a more efficient and scalable solution for issuing tokens.

Conversely though, the protocol is still young and has had to deal with some adversity. Proponents of BRC-20 feel that Runes projects are too centralized, while others feel Rodarmor’s design was nothing more than a cynical money grab. Only time will tell if they will survive and even thrive. As Samson Mow told me in an interview last year at Bitcoin Miami, “it’s just noise”. 

It pays to zoom out and see where other chains like Ethereum and Cardano are heading, and what’s possible with new protocols and even Layer-2 chains for Bitcoin. When mining rewards become negligible in the next 10 or 20 years, the network will have to rely on transaction fees to keep the miners from revolting and shutting down their machines. Innovations like Runes are asking the right questions in order to get them to stay.

Layer-3 (L3) Networks: Climbing Crypto’s Next Frontier

Posted on by Werner

Intermediate Level Introduction

Web3 and DeFi continue to grow and mature, and any established smart contract platform blockchain requires scaling and speed to keep up with user demands, causing a new frontier to emerge: Layer-3 chains. 

These cutting-edge solutions are designed to build upon the foundation of Layer-1 and Layer-2 technologies, bringing forth a new era of scalability, interoperability, and specialized functionality.

Understanding the Blockchain Layers

Credit: Werner V.

To understand why Layer-3 networks are being touted as integral to the future success of crypto, it’s essential to understand the role of each layer in the blockchain ecosystem.

Layer-1: The Foundation

Also called the base blockchain, Layer-1 networks, such as Bitcoin, Ethereum, Solana and Cardano form the bedrock of the blockchain world. They provide stability and battle-tested security to the projects that build on them, and rely on them to keep their assets safe. 

Bitcoin and Ethereum are the two biggest L1 blockchains in the world. L1 blockchains are the basic infrastructure and security layer that Layer 2 (L2) blockchains build on. These networks provide the core functionalities, consensus mechanisms, and security protocols that decentralized transactions and applications require.

Layer-2: Scaling Solutions

Layer-1 networks face scalability challenges; Ethereum can process only 14 transactions per second maximum. So Layer-2 solutions have emerged in the last two years to address these limitations. 

A Layer-2 chain is a secondary protocol that is built on top of an existing Layer-1 blockchain. 

The primary purpose of Layer-2 chains is to improve the scalability and efficiency of the whole blockchain by handling transactions off the main ledger. This approach helps alleviate the network congestion. It also reduces the transaction costs – which are often high on Layer-1 blockchains due to their limited throughput. 

Popular examples of Layer-2 solutions include the Lightning Network for Bitcoin and Optimism and Arbitrum for Ethereum. Layer-2 solutions employ various techniques like state channels, sidechains, rollups, and plasma, each with distinct mechanisms for moving transactions off the main blockchain.

As such, Layer-2 chains are critical in blockchain architecture, offering a balance between decentralized security and high scalability.

Optimistic vs ZK Proof Rollups

Rollups execute transactions outside the main chain, but post transaction data back to it. This setup enables higher transaction throughput while coming back to the robust security of the Layer-1 blockchain. 

Ethereum rollups can broadly be divided into two camps, namely optimistic rollups (OR) and zero-knowledge proof (ZK) rollups. 

Optimistic rollups like Optimism (Coinbase’s Base Network used its OP stack to build its chain) and Arbitrum assume transactions are valid by default, and only run computations in the event of a dispute, which significantly reduces the burden on the main blockchain but entails a waiting period of up to seven days for withdrawals to ensure security. 

In contrast, ZK rollups like ZkSync and Stark use zero-knowledge proofs to validate all transactions off-chain before bundling them back to the main chain, providing immediate finality and reducing wait times but requiring more complex computation upfront. Vitalik Buterin, Ethereum creator, is a big fan of ZK rollups as they enable you to validate data without the need to share your private information. 

Layer-3: The use case-specific layer

However, if the world wants to all transact and send data on one chain like Ethereum or Solana, we need to go bigger and faster. This is where Layer-3 chains come in. 

Layer-3 networks focus on enabling seamless interoperability between different blockchains while providing specialized functionality tailored to specific use cases. Think of them as specialized, custom-built chains created for specific use cases, such as Web3 gaming or DeFi trading. 

Key Features of Layer-3 Networks

Layer-3 networks offer distinct advantages that set them apart from their predecessors:

Enhanced Scalability and Efficiency

By optimizing consensus mechanisms and data structures, Layer-3 networks achieve higher transaction throughput and processing capabilities. This allows decentralized applications (dApps) to perform with extreme efficiency, minimizing network congestion and computational bottlenecks.

Improved Interoperability and Accessibility

One of the key benefits of Layer-3 networks is their ability to seamlessly communicate and transfer assets between different blockchains. This interoperability means the crypto ecosystem becomes more connected and more accessible, enabling users to navigate and bridge across various networks with ease and far less risk.

Customization and Security

Layer-3 networks usually host only one dApp per network. This allows developers to customize their chains to their satisfaction, and implement security features tailored specifically to their dApp’s requirements. By providing a dedicated environment for each application, Layer-3 networks ensure optimal performance and enhanced security.

Notable Layer-3 Projects

Several promising Layer-3 projects have emerged, each bringing its own set of innovative features and use cases to the table.

Orbs

Orbs positions itself as a Layer-3 infrastructure project, bridging the gap between Layer-1, Layer-2, and the application layer. By providing an intermediary execution layer, Orbs enhances smart contract capabilities and introduces groundbreaking DeFi protocols such as dLIMIT, dTWAP, and Liquidity Hub.

Degen Chain

Built on the Base blockchain, Degen Chain is a Layer-3 platform designed to efficiently handle payment and gaming transactions. With its thriving ecosystem of tokens and rapid growth, Degen Chain aims to tackle scalability issues while maintaining low transaction costs.

Social media influencers have relentlessly shilled the chain in recent weeks for potential airdrops, and attracted a lot of investment as a result. 

Arbitrum Orbit

Arbitrum Orbit enables developers to create customizable Layer-2 or Layer-3 chains within the Arbitrum ecosystem. These chains can settle transactions on Arbitrum One, providing developers with the flexibility to tailor their application’s features and governance to their specific needs.

Other notable Layer-3 projects include Cosmos IBC, Polkadot, Chainlink, Superchain, and zkHyperchains, each contributing to the evolution of the blockchain landscape in their own unique ways.

Potential Impact and Use Cases

Layer-3 networks hold immense potential for the future of blockchain technology. Here are a few of the biggest plusses.

Decongesting the Main Chain

By processing transactions off-chain, Layer-3 solutions help alleviate congestion on the main blockchain. This leads to reduced network congestion and lower transaction fees, improving the overall user experience.

Enabling Complex dApps

The specialized functionality offered by Layer-3 networks opens up new possibilities to develop sophisticated and user-friendly dApps across sectors like DeFi, gaming, and social media. By providing a tailored environment for each application, Layer-3 networks enable developers to create highly optimized and efficient dApps.

Driving Mainstream Adoption

The ability to create customized, high-performance applications lowers the entry barrier for businesses and individuals, fostering a more inclusive and diverse crypto ecosystem.

Challenges and Considerations

While Layer-3 networks present exciting opportunities, they also face certain challenges that need to be addressed.

Centralization Concerns

Some critics argue that Layer-3 networks, being built on top of potentially centralized Layer-2 solutions, may further compromise the decentralization principles that is the soul of blockchain technology. Striking the right balance between scalability and decentralization remains a crucial consideration for Layer-3 networks.

Competition and Fragmentation

As more Layer-3 networks enter the fray, competition for users and developers is likely to intensify. This could lead to fragmentation within the crypto ecosystem, with liquidity and resources being spread across multiple platforms. Ensuring a cohesive and interconnected ecosystem will be a key challenge for Layer-3 networks.

Conclusion

Layer-3 networks can make blockchain technology. By building upon the foundations laid by more scalable, interoperable, and specialized than ever before. As the crypto landscape continues to mature, Layer-3 networks are poised to play a crucial role in shaping its future.

For beginners navigating the complex world of cryptocurrencies, understanding the significance of Layer-3 networks is essential. By staying informed about these cutting-edge developments, individuals can position themselves to capitalize on the opportunities presented by this next-generation technology.

As the blockchain ecosystem continues to evolve, Layer-3 networks will undoubtedly face challenges and obstacles. However, the potential benefits they offer in terms of scalability, interoperability, and specialized functionality are too significant to ignore. As more projects emerge and mature, the true impact of Layer-3 networks will become increasingly apparent.
