Analysis BTC latest inscription project of the RGB ecology of the smart contract layer: BitRGB & UniPort

The explosion of Ordinals has brought the narrative of BTC ecology back to public attention, and the BRC 20 token led by Ordi has stirred up a thousand waves with one stone, setting off a BTC new asset in the crypto circle Summer. Ordinals/ BRC 20 is only a small track in this round of BTC ecological narrative, and there are many subdivided track projects in the pipeline, all of which are expected to take over the baton of Ordinals and lead the BTC ecology to continue to move forward.

Introduction to the RGB protocol

As the most well-known smart contract protocol on the BTC, RGB is backed by a number of star institutions including Fulgur Ventures, Bitfinex, Hojo Foundation, Pandora Prime, and DIBA.

The official definition of RGB is a suite of protocols for scalable and confidential smart contracts for BTC and the Lightning Network, which can be used to issue and transfer assets and rights more generally. In short, RGB can be used to issue BTC new forms of assets that are scalable, composable, and support smart contract scenarios.

Here’s an analysis of potential projects built on the RGB open-source license:

1）BitRGB

BitRGB is an RGB-based BTC asset management platform that supports the issuance and trading of BTC assets such as NFTs/tokens, etc. The protocol leverages the paradigm of client-side verification to keep all BitRGB-related transaction data off-chain, using only the BTC blockchain as a commitment layer to prevent the double-spend problem.

Based on the BitRGB protocol, it can realize the issuance and trading of BTC assets, as well as more diversified smart contract scenarios, and achieve higher scalability, privacy and programmability.

Asset Class

BitRGB is the BTC new asset issuance platform, and the platform supports assets in 3 different formats: RGB 20/ RGB 21/ RGB 22. Each asset class has specific characteristics and uses. Among them, RGB 20 stands for fungible token, which can be compared to BRC 20 tokens, RGB 21 token is non-fungible token, which can be compared to Ordinals NFT, and RGB 21 stands for DID, which can be used in various fields such as identity authentication and access control.

Recent News:

It was officially announced that the platform’s first RGB 20 asset, RGBS, will be released in the near future. Join Discord and complete platform tasks to get a whitelist airdrop.

2) UniPort

UniPort is a full BTC-chain interoperable cross-chain protocol launched by Satori Lasb, which supports bringing BTC emerging assets such as RGB 20/ BRC 20 / Taproot Assets into the smart contract system. By providing a complete cross-chain infrastructure, UniPort will effectively release the liquidity of BTC huge amount of precipitated assets.

UniPort Roadmap announced that it will support more and more blockchain networks in the later iteration and upgrade, and will integrate Cosmos ecological chain, Solona, Aptos/ Sui and other Move ecological chains, aiming to become a hub connecting any blockchain network. The current version has full support for EVM-compatible public chains.

Technical Implementation

UniPort initially launched the asset cross-chain technology to realize the management of cross-chain assets based on multi-signature alliances.

For the cross-chain of BTC ecological assets, UniPort plans to adopt multiple innovative mechanisms to ensure the security and decentralization of cross-chain transactions, including: economic design and reserve management mechanism, node staking and rotation mechanism, security and anti-malicious behavior mechanism. For more information on the above-mentioned innovative mechanisms, please refer to the official documentation.

For smart contract chain asset cross-chain, UniPort plans to introduce zero-knowledge proofs and light client verification to achieve more secure and efficient asset cross-chain. In addition, UniPort has optimized the existing zk proof generation system and proposed the UniVirgo proof system, which combines the advantages of the ZKP algorithm Libra and Virgo. With the launch of the UniVirgo zk proof generation system, the proof size and validator cost for on-chain verification will be greatly reduced.

In general, for BTC emerging assets, the implementation of asset cross-chain is a rigid need, so UniPort, as a cross-chain interoperability protocol for the BTC ecosystem, is driven by demand, and the product version is planned to be complete and decentralized, with a clear technical implementation path and strong implementability.
