About 4.5 billion years ago, the Earth formed.About 3.5 billion years ago, single-celled organisms began to wriggle.About 300,000 years ago, Homo sapiens emerged as modern humans.About 150 years ago, the underlying code of modern computers started to operate rapidly.About 14 years ago, the first block of the Bitcoin blockchain, known as the "Genesis Block," was created, marking the beginning of the entire Bitcoin network.Just a few months ago, GPT-4.0 was released, coinciding with substantial breakthroughs in the core technologies behind Bitcoin.At this very moment, as you read these words, you might be filled with curiosity and puzzlement about RGB....In the world of cryptocurrency, Bitcoin undoubtedly stands as the most well-known presence. However, when people discuss Bitcoin, they often focus solely on its price, market cap, and trading volume, neglecting its technological innovations and potential applications. Many of the core technologies we mentioned in last year's "DeFi on the Bitcoin Lightning Network" research have seen substantial breakthroughs in the first half of this year, such as:

...Talking of the RGB protocol, people might find familiar and unfamiliar with it. We are familiar with the concept of RGB when it was first proposed in 2016. Many people are aware of the existence of the RGB protocol, yet despite several years of development, it has not garnered widespread attention and application. Specific use cases for the RGB protocol also seem elusive.Based on our research and analysis, we believe the primary reason for this phenomenon is that the early versions of the RGB protocol had limited functionality. Additionally, the idea behind the RGB protocol is highly original and unique, requiring an extensive understanding of both Bitcoin and smart contract principles for developers to effectively engage with it. However, as the RGB protocol continues to evolve and refine, this situation is changing.

What is RGB?

Introduction to RGB

RGB is an scalable and confidential smart contract system for Bitcoin and the Lightning Network, developed by the LNP/BP Standards Association. It employs concepts of private ownership and joint ownership and constitutes a Turing-complete, trustless form of distributed computation, obviating the need for token-introducing off-chain decentralized protocols.The design objective of RGB is to enable scalable, robust, and private smart contracts to run on UTXO (such as Bitcoin), facilitating a realm of possibilities. Through RGB, developers can execute tasks like token launch, NFT (Non-Fungible Token) mint, DeFi, DAOs, and more intricate multi-category smart contracts.The RGB protocol builds upon the concepts of client-side validation and single-use seals initially proposed by Peter Todd in 2016. It functions as a client-side state validation and smart contract system operating on the layer2 and layer3 (off-chain) of the Bitcoin ecosystem. Peter Todd's original paper: https://petertodd.org/2017/scalable-single-use-seal-asset-transfer

Client-side validation

Client-side validation is a solution introduced by Peter Todd in 2016. Its core concept revolves around the notion that in a distributed system, state validation does not necessitate a global execution by all participants involved in a decentralized protocol. Instead, validation is required only from parties involved in specific state transitions. By adopting this approach, state transitions are not launched across the entire network but are transformed into simple cryptographic commitments through the use of crypto hash functions and similar techniques. These commitments need to be part of "Proof-of-Publication" , encompassing the key attributes of receipt proof, non-publication proof, and membership proof.The first client-side validation system is the OpenTimeStamps protocol, which was also proposed and developed by Peter Todd between 2014 and 2016.

Single-use seals

These can be likened to the real-world disposable seals used to secure shipping containers. The explanation of a single-use seal is a distinct object that encapsulates a message in a one-time manner, ensuring that this message can only be used once. Once used it is permanently opened and cannot be sealed again. In essence, single-use seals represent an abstract mechanism aimed at preventing double-spending.

A brief history of RGB

The initial concept of RGB can be traced back to 2016 when Giacomo Zucco (BHB Network) proposed it based on early ideas from Peter Todd regarding client-side validation and single-use seals. In 2017, the original MVP of RGB was implemented by BHB Network, with support from the Poseidon Group.In 2019, Maxim Orlovsk and Giacomo Zucco jointly established the LNP/BP Standards Association (https://www.lnp-bp.org) with the aim of advancing RGB from conceptualization to practical implementation. This association garnered support from Fulgur Ventures, Bitfinex, Hojo Foundation, Pandora Prime, and DIBA.

Maxim OrlovskStarting from 2019, Dr. Maxim Orlovsky has assumed the role of primary architect and chief contributor for the RGB protocol, designing and implementing its current form. Since 2019, RGB has undergone rethinking and redesign in terms of its design and protocol peer reviews, evolving into a versatile computational and confidential smart contract system.In 2021, the LNP/BP Standards Association successfully published a pure functional RISC virtual machine (AluVM), and RGB began operating on the Lightning Network. This implementation utilizes the Rust language (LNP Node) of the complete Lightning protocol.In 2022, the LNP/BP Standards Association launched a new website (contractum.org) concerning the Contractum language, a novel high-level language. This language is designed for scripting RGB smart contracts on Bitcoin and the Lightning Network. Contractum serves as a functional declarative programming language, are tailored for smart contract development using RGB technology.In April of 2023, the LNP/BP Association announced the release of RGB v0.10, marking significant milestone in the development of the RGB protocol. This version brings full support for smart contracts to Bitcoin and the Lightning Network. It is a testament to the extensive collaborative efforts across Bitcoin developers, contributors, related companies, and over four years of broad development work. (RGB v0.10 can be downloaded and installed from https://rgb.tech, which also provides various user and developer guides. The RGB source code can be found at https://github.com/RGB-WG.)

RGB background

For many years, various teams have been engaged in researching protocols for token launch on Bitcoin and attempting to achieve compatibility with the Lightning Network. Notable examples include OmniBOLT, Taproot, and RGB.One of the well-known protocols for token issuance on Bitcoin is OmniLayer. Its working principle involves inserting metadata into Bitcoin transactions to "color" them, signifying that the transaction should be understood as a token transfer. The USDT (Tether) within the Omni protocol can be considered a form of colored coin. In the Omni protocol, USDT exists as Tether tokens, represented through specific transaction types of the Omni protocol within Bitcoin transactions. Specifically, when a user initiates a USDT transaction on the Omni protocol, a special data field from the OmniLayer is added to the Bitcoin transaction. This indicates that the transaction involves the transfer of USDT tokens. This approach enables Bitcoin transactions to represent the transfer of USDT tokens, and holders of USDT can use Bitcoin addresses to receive, to send, and to store USDT tokens.Such signalling would usually happen in an OP_RETURN output, which is off-course ignored by normal Bitcoin nodes, but can be interpreted by the token protocol aware nodes, which will enforce the token protocol validation rules.

While this design is effective, it also presents a few drawbacks:

RGB’s Solution: Moving off-chain

With the goal of improving on this design, the RGB project proposes a more scalable, more privacy aware and more future proof solution based on the concept of client-side validation and single-use seals, initially proposed by Peter Todd in 2017.The core of the idea is to use the Bitcoin blockchain only for what it is indispensable, that is leveraging its proof-of-work and network decentralisation for double-spending protection and censorship-resistance. All the token transfer validation work can instead be moved out of the global consensus layer, and kept off-chain, delegating it to only the client receiving the payment.

Working Principle

In RGB, basically tokens always need to be assigned to a Bitcoin UTXO (either already existing or created ad hoc). To move the tokens, you need to spend such UTXO. While spending the UTXO, the Bitcoin transaction will have to include a commitment to a message containing the RGB payment information, defining input(s), Bitcoin UTXO(s) where the tokens will be sent to, asset id, amount, spending conditions and other extra data you may want to attach.

If you have tokens assigned to the Output 1 of Bitcoin transaction A, to move them you would need to create an RGB transaction and a Bitcoin transaction spending from Bitcoin TX A: output 1 committing to the RGB transaction. As you can see, the RGB transaction is moving tokens from Bitcoin TX A: output 1 to Bitcoin TX C: output 2 (which is not shown in this diagram), not towards any output of Bitcoin TX B. In most cases, we can expect TX B output 0 to just change addresses to send the satoshis owned by the UTXO being spent back to the owner minus the fee, while committing to the RGB transaction to avoid the possibility of double spending.

Privacy Protection

To move RGB tokens that were assigned to a Bitcoin UTXO, a Bitcoin transaction is always needed. However, the output of the RGB transfer does not need to be the same as the output of the Bitcoin transaction. As we can see in the example above, the RGB transaction (Bitcoin TX C: output 2) is completely unrelated to the Bitcoin TX B. This means that RGB tokens can “teleport” from one UTXO to another without leaving any trail in the Bitcoin transaction graph. This is great for privacy!In this design, Bitcoin UTXOs are used as single-use seals containing RGB assets, and to move the assets you essentially need to open the new seal and close the old one.The RGB specific payment data is transmitted off-chain through a dedicated communication channel, from the client of the payer to the one of the receiver which will proceed in verifying that RGB protocol rules were respected. In this way, a blockchain observer will not be able to extract any information about the activity of RGB users.

Validation Loop

Validating the incoming payment is not enough to make sure the sender actually owned to assets just sent to you, therefore, to consider the received payment as finalised, you would have to receive from the payer also all the history of the transactions related to the token just sent, back to the very original issuance. By validating all the transaction history, you can make sure the asset has not been inflated and that all spending conditions attached to the asset were always respected.This design helps with scalability as you don’t have to validate the entire history of the asset, but only those transactions that are relevant to you. Moreover, the fact that the transactions are not broadcast to a global ledger improves privacy, as fewer people are aware that your transaction even exists.

Blinding secrets

With the goal of further improving privacy, RGB support the blinding of outputs, which means that in the payment request you share with whoever need to pay you, you do not disclose the UTXO where you want to receive the tokens. Instead, you can ask the payer to send the tokens to a hash, which you generated by concatenating the UTXO itself with a random blinding secret. In this way, the payer will not be aware of the UTXO to which the tokens are being sent to, making it therefore impossible for an exchange or other service providers to know if they are operating a withdraw towards a UTXO “blacklisted” by some regulatory agency, or to monitor when the tokens will be spent in the future.When tokens are spent, the blinding secrets have to be revealed to the receiver so that she can verify all the Bitcoin part of the transaction history. This means that with RGB you have total privacy in the present, but future token holders will be able to see all the UTXOs that were involved in transfers. Therefore, while enjoying perfect privacy when receiving and holding the tokens, the confidentiality of user’s past financial activities degrades over time as the tokens are successively moved between people, approaching the same privacy level we enjoy for our past Bitcoin transaction history.

Main features of RGB

Based on the understanding of the aforementioned content, we can summarize that RGB exhibits the following key features:

It's noteworthy that when referring to blockchain, the concepts of blocks and chains usually come into play. However, RGB does not involve the notions of blocks and chains, as it is a client-side validation technology and a non-block decentralized protocol.

The Infinite Possibilities of RGB v0.10

The release of RGB v0.10 marks a significant breakthrough, advance RGB to the stage where it is about to be commercially available. It introduces the final consensus-breaking changes aimed at maintaining full backward compatibility for future RGB versions. Moreover, it unlocks the last set of features for realizing fully functional smart contracts, which can be tailored as per the discretion of contract developers.The release of RGB v0.10 encompasses the consensus layer, standard libraries (used for wallet/exchange integration, etc.), and command-line tools. The following table summarizes the main differences between the new and previous versions based on official RGB materials:

For more comprehensive details, readers can refer to the official RGB documentation and video introductions available at:https://rgb.tech/blog/release-v0-10/https://www.youtube.com/@LNPBP/videos

Interpreting RGB v0.10

In essence, the v0.10 version of the RGB protocol addresses a multitude of issues present in previous versions, encompassing constraints on smart contract development, interaction with the consensus layer, limitations on encoding formats, dependencies on Rust Bitcoin, missing WASM compatibility, global state and context management challenges, integration concerns with the Lightning Network, inflexibility in backup processes, inadequate support for mobile wallets, and more. These enhancements render the RGB protocol more potent, versatile, and secure, establishing a robust foundation for future growth. This release brings the support of the following features to RGB:

Global state in RGB contracts

Contract interfaces

Strict type system

Contracts in Rust

State introspection

URL-based invoice format

WASM support

Tapret descriptors and custom derivation

Simplified dependencies

Simplified integration

Simplified UX

What are the significant breakthroughs in RGB v0.10?

As mentioned earlier, we discussed the primary reasons we believed contributed to RGB not gaining widespread attention and adoption despite several years of development. However, after delving into the study of the RGB v0.10 version, we have valid reasons to believe that this phenomenon is on the verge of change, or rather, that change is already underway.

Why couldn't independent developers engage in complex smart contract development in previous versions?

In versions preceding RGB v0.10, independent developers faced certain challenges when attempting complex smart contract development. This was primarily due to several factors below:

However, as the RGB protocol evolves, these issues are being addressed. For instance, the introduction of a new type system named strict types in RGB v0.10 can assist developers in tackling complex smart contract development with greater ease. Furthermore, this version offers additional tools and resources to aid developers in comprehending and utilizing the RGB protocol.

Enabling full support for smart contracts within the Lightning Network has become feasible.

Due to its foundation on Bitcoin, the utilization of the Lightning Network for the transfer of RGB assets is theoretically viable. However, in previous iterations, RGB couldn't be utilized within any existing Lightning nodes due to architectural constraints. In 2021, RGB developed its own architecture known as the LNP Node, implemented in Rust. It stands independently from Bitcoin Core, and for users aiming to integrate RGB with Taproot on the Lightning Network, they awaited completion of Taproot support by Rust-Bitcoin.With the release of RGB v0.10, the LNP/BP Association has now outlined their forthcoming priorities. Their focal point is directed towards accomplishing Lightning Network support in the coming months, facilitating the capability to transfer RGB assets via the Lightning Network.If RGB achieves compatibility and support with the Lightning Network, it can enhance the liquidity and accessibility of RGB assets. Through the Lightning Network, users can swiftly and cost-effectively transfer RGB assets without waiting for confirmation on the Bitcoin mainnet. This is particularly beneficial for users who engage in frequent trading of RGB assets.Furthermore, RGB could potentially bring full smart contract capabilities to the Lightning Network. The Lightning Network boasts remarkable speed, minimal fees, and exceptional security. However, due to Bitcoin's inherent lack of support for complex smart contracts, the Lightning Network has faced certain limitations in this aspect.RGB's ability to support intricate smart contract functionality stems from its deliberate design tailored to smart contract implementation on the Lightning Network. Primarily, RGB employs a Turing-complete virtual machine known as AluVM, a powerful computational engine that permits the execution of sophisticated smart contracts on the Lightning Network. AluVM empowers RGB to handle complex computational logic and data operations, enabling a wide range of smart contract types.In its design, RGB thoroughly considers the characteristics and requirements of the Lightning Network, potentially bestowing upon the network the capacity to fully support complex smart contracts. Whether it pertains to DeFi, NFTs, GameFi, or SocialFi, RGB holds the potential to materialize on the Lightning Network.This unparalleled combination could not only elevate the Lightning Network to a radiant star but also potentially outshine other blockchain platforms. With an increasing influx of funds and developers into the development of the Bitcoin Lightning Network and RGB, there is a promising prospect of propelling the Bitcoin and Lightning Network ecosystem to unprecedented heights.

RGB vs. Other Alternatives

Altcoins based tokens

Most of the altcoins based token protocol (e.g. ERC-20) offer smart contracts with a global unowned state, which enables easy to deploy DEXes and other financial applications, but they are hard to scale, with no privacy and inherit all the drawbacks of those altcoins, such as high costs to run a node, lower decentralisation and less resistance to censorship attacks.

Liquid assets

Liquid is a federated Bitcoin sidechain that offers some interesting features such as native assets support and confidential transactions to hide from blockchain observers the payment amount and the ID of the asset being transferred. However, the federated model presents again the problem of low decentralisation and little censorship resistance.

OmniBolt

OmniBOLT is a Lightning Network-compatible version of OmniLayer. OmniLayer was briefly introduced earlier (interested readers can also refer to the "DeFi Research on the Bitcoin Lightning Network" for a more detailed explanation).The considerations behind OmniBOLT closely resemble those of RGB. The distinction lies in the differing design objectives of these two protocols. In comparison to RGB, OmniBOLT exhibits relatively weaker privacy attributes, as token-related data, much like Bitcoin, remains stored on the chain. However, OmniBOLT possesses a distinct advantage in stablecoin payment operations and has undergone the test of time. In June of this year, its Mainnet went live, enabling the sending, receiving, and transferring of USDT through the Lightning Network.

Taproot (Taro)

Announced during the Bitcoin 2022 Miami conference, Taro is a project backed by Lightning Labs with the goal of bringing assets on top of the Lightning Network. According to the released specifications, the design is very similar to RGB, with basically the same features and trade-offs. At the time of writing, the main difference between RGB and Taro seems to be that RGB has already released some reviewable code while taro is only specs, but on the other hand you could argue that Taro is backed by one of the best teams in the lightning ecosystem, creating good expectations for a future implementation. Given the similarities of the two designs, it would be nice if Taro and RGB ended up being interoperable, but only time will tell if the right incentives for this to happen will ever materialise.

Evolution of the RGB Protocol: A New Era of Possibilities

From its initial conception to the present, the RGB protocol has undergone nearly six years of evolution. While the protocol has yet to garner widespread attention and adoption, historical experience teaches us that the rapid dissemination of novel ideas is often overestimated, while the potentially disruptive impact and pace of acceptance of these concepts are underestimated. In reality, with the introduction of RGB protocol version 0.10, we find ourselves at a fresh starting point, witnessing a future full of boundless potential, much like that of Bitcoin.The all-new version of the RGB protocol introduces a series of significant updates, enabling the issuance and transfer of various assets on both the Bitcoin network and the Lightning Network. Moreover, the protocol now possesses the capacity to support more complex smart contracts. While complete compatibility with the Lightning Network is yet to be realized, we firmly believe that the LNP/BP Association and the related development teams are poised to make substantial strides in the coming months. With our hopeful anticipation of the seamless integration of RGB protocol and the Lightning Network, this will mark another significant milestone in the collaborative journey of RGB protocol and Bitcoin.The new functionalities and improvements brought by the RGB protocol, particularly its full compatibility with the Lightning Network, illuminate a path toward Bitcoin's future. These transformations open doors to uncharted territories, allowing us to glimpse the boundless potential of Bitcoin. In this uncharted domain, Bitcoin transcends being merely a simple means of payment; it evolves into a robust platform capable of hosting intricate applications. The RGB protocol, in turn, serves as the cornerstone to construct this platform, potentially guiding us into an entirely new realm of the Crypto world.References:
