Why Celestia

Throughput
no one else has.

Unlike legacy blockchains, Celestia separates compute and storage so each can scale independently. We built Fibre to accommodate 1 Tb/s of data throughput (625M+ transactions per second), so you can move your business onto blockchain rails, no matter how ambitious your vision.

Built by us.
Owned by you.

We design the infrastructure, ship the chain, and hand it over production-ready. You control the infrastructure, the roadmap, and the economics from day one.

High Potential Businesses
Built on Low Fees

Celestia enables you to offer low cost payments and financial transactions to your users that you can scale into real revenue. With Fibre, you can easily sustain 1M TPS, charge your users $0.0001 per transaction, and generate $3B+ in annual revenue.
