Celestia (TIA) is a blockchain network designed to allow anyone to launch their blockchain with minimal overhead costs. It achieves scalability by fundamentally reimagining blockchain architecture and creating a lean model. This model separates the consensus from execution by incorporating a new component known as data availability sampling. As Celestia does not enforce specific execution or settlement restrictions, developers have free reign to devise their own execution and settlement protocols, unveiling untapped opportunities. 

Celestia aims to differentiate itself from other blockchains, which often encounter scalability issues due to inherent functions such as transaction processing, validation, and orchestration. Modular blockchains, conceptualized by Celestia, decouple consensus from transaction execution, thereby improving scalability without compromising security or decentralization.

This modular structure opens a wide range of new possibilities. The ease of experimentation is enhanced as both specific and multi-purpose blockchains can find a place within the Celestia ecosystem, securing their environment directly from Celestia's established validator set. Such modular blockchains enable developers to make adjustments to their technical frameworks without any external constraints, thereby independently controlling their application rules. #TIA
