It's a decentralised p2p (blockchain-like) platform but the main difference being that the consensus is decided by one central server designed specifically for smaller communities and events which can be online/offline (for eg. reddit/hackinout)

We’re participating in Based India because we want to make going onchain easier and more approachable for everyone. With Castmoney, we aim to create a platform where users can bring their friends onchain in a way that feels simple, social, and not intimidating. In India, investment decisions are often influenced by social networks, whether it’s family gatherings or friend groups discussing market trends. We want to build on this cultural insight by making it easier for people to explore DeFi with their social circles. Imagine a scenario where even kitty party aunties are excitedly sharing which memecoins Sharma ji's son just bought, lol. Castmoney aims to leverage this inherent social behavior and make investing in DeFi a shared, trusted experience. Over the last few years, our team has actively contributed to the Ethereum ecosystem in India. We’ve been advocates for the community constantly pushing to get more builders involved onchain. Through onboarding our IRL friends into crypto, we’ve seen firsthand what confuses or overwhelms them. Castmoney is our solution to address these challenges and make the onboarding experience smoother for newcomers. Our team is born and raised in India and we’ve been deeply involved in growing the Ethereum India ecosystem. Participating in Based India is a way for us to give back to the region and help drive the adoption of base and ethereum further within our social circles through Castmoney.
