Using brc20-sats as L2 gas has several considerations:
- 1.Wide Distribution: brc20-sats are the most widely distributed brc20 assets to date, with the largest number of holding addresses. This wide distribution makes it a practical choice.
- 2.Fine-Grained Value Measurement: brc20-sats have a relatively small unit, allowing for precise value measurement. This is especially valuable in situations where small amounts of value need to be calculated and transferred.
- 3.Consistency with Layer 1: Using brc20-sats as L2 gas maintains relative consistency with the use of Bitcoin-sats on the Layer 1 network. This consistency can simplify the user experience and provide continuity in value representation between the two layers.
In summary, using brc20-sats as L2 gas offers practicality due to their widespread distribution, fine-grained value measurement, and consistency with Bitcoin-sats used on Layer 1. These factors contribute to a seamless and user-friendly experience in both L1 & L2 of the network.
UniSat offers two types of rewards to users who provide liquidity:
- 1.Service Fee: Liquidity providers receive a portion of the swap service fee as a reward for their participation.
- 2.Staking of LP Tokens: UniSat provides a farming mechanism, enabling third-party developers to establish their staking models. This allows for additional rewards to be offered for specific swap pairs.

Anyone can implement their own modules, which is permissionless, much like UniSat has done with the brc20-swap module. All newly created modules start in 'black module' mode by default, meaning that all indexers treat them as blackboxes, not recognizing their contents.
To provide services to their users, module providers must independently index data within their modules. All activities within these modules remain hidden from the external world and have no impact on the existing brc-20 ecosystem.
Once the main indexers (Alex, Domo, Hiro, OKX, UniSat) are ready to recognize brc20-swap operations and are satisfied with its performance (let's assume that they are happy with it), the brc20-swap module has the opportunity to be 'accepted' and become a part of the brc-20 as one 'white module'.
Looking ahead, the core protocol will remain stable and straightforward. Many modules supporting various protocols, blockchains, and domains will be introduced. Some of these modules will gain acceptance from the main indexers.
This approach allows brc-20 to remain highly adaptable, permissionless (meaning anyone can create modules), decentralized (as indexers can choose which modules to support), and sustainable (modules are isolated without interfering with each other), all while keeping the core protocol simple and stable.
Numerous modules are currently in development (Sep. 2023), aiming to support different protocols, blockchains, and domains. brc-20 is showcasing its robustness and vitality through its inherent simplicity.
In the 'black module' state, the main indexers lack detailed information about the module. Allowing direct withdrawals in this state would result in varying states across different indexers, potentially causing chaos in the entire system. This is why direct withdrawal is not an option for 'black modules.'
Nevertheless, there are multiple workarounds available. The most straightforward approach is to utilize existing marketplaces, where users can trade in-module assets (L2 assets) for classic brc-20 assets (L1 assets).
However, we offer a simpler solution: when a user requests a withdrawal, they simply submit the withdrawal request. If there is someone depositing assets, the deposit and withdrawal processes will automatically and atomically exchange, ensuring a smooth and atomic deposit/withdrawal happening at the same time.
To address the congestion challenges on the Bitcoin mainnet, UniSat has developed a sequencer capable of rolling up thousands of swap operations, including adding liquidity, removing liquidity, and swapping assets. The resulting rollup inscription is then submitted to the Bitcoin mainnet.
What makes this sequencer truly remarkable is its versatility. It's designed in a way that allows it not only to roll up swap operations but also to be extended to support various advanced operations in the future.
It's quite encouraging that we now have a comprehensive Layer 2 solution with Ordinals on Bitcoin, all achieved elegantly. This achievement highlights the inherent strength of brc-20 and showcases its potential for further innovation.
To provide a more feature-rich experience, the current main indexers may show interest in implementing useful and highly reliable modules. This becomes even more likely when the source code is available for thorough review and reference.
In the ever-evolving ecosystem, An indexer is expected to communicate well with others and make decisions thoughtfully about supporting different modules. If it remains stagnant may find itself outperformed by newer counterparts and risk losing support over the long term.
Ideally, having the support of all indexers for a module would be fantastic. However, it's essential to acknowledge that in reality, there might be cases where most indexers adopt a module while the rest have reservations and choose to step back without following. In such scenarios, the indexer is risking being orphaned, which reflects the reality well.
The governance of brc-20 is a journey that stretches into the future. UniSat holds immense respect for other participants in this field and wholeheartedly supports the development of a robust and ever-evolving ecosystem.
