RGB can scale in terms of transaction throughput, data size and network size. It doesn't keep any data on-chain (in any blockchain); it is sharded from day 1 and is fully interoperable with layer 2 scalability solutions.
No chain analysis is possible due to the absence of a transaction graph in blockchain. RGB uses zero-knowledge to protect the history of a fungible state. With RGB, the user is always in-charge of when, and what parts of the history and state to disclose, if needed.
Bitcoin & Lightning
RGB is a native member of Bitcoin and the Lightning Network ecosystem, bringing rich smart contracts in a scalable way to the World's most secure and censorship-resistant cryptocurrency.
