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 the day 1 and is fully interoperable with layer 2 scalability solutions.
No chain analysis is possible due to the absence of transaction graph in blockchain. RGB uses zero-knowledge to protect the history of a fungible state. With RGB, user is always in-charge what and when to disclosure parts of the history and state, if needed.
Bitcoin & Lightning
RGB is a native member of Bitcoin and Lightning network ecosystem, bringing rich smart contracts in a scalable way to the World's most secure and censorship-resistant cryptocurrency.
