Consumer apps represent a pivotal shift in blockchain technology, catering to the needs of everyday users. It aims to turn decentralized apps once considered niche to only crypto enthusisatics to a solution easy-to-use and attractive to mainstream adoption.<br>

Concha is built as a Layer 3 (L3) solution on Bitcoin for several reasons. Firstly, leveraging Bitcoin's secure and well-established network provides a solid foundation for Concha's operations. Secondly, by synchronizing its state with Rootstock, a trusted Bitcoin Layer 2 (L2) solution, Concha enhances its scalability and interoperability while maintaining the security of the Bitcoin network. Additionally, positioning Concha as a consumer-focused L3 solution on Bitcoin allows for fast and cost-effective transactions, paving the way for widespread adoption of decentralized applications (dApps) among mainstream users.
