Centrifuge blockchain is public or semi-private?
Does the blockchain Solidity smart contracts?
What is the price of the network fees? Does your blockchain use a transactional protocol as ghost protocol?
Why is having a tokenization dapp in your blockchain better than in other networks?
How can I deploy smart contracts on Centrifuge blockchain?
When will the Centrifuge parachain be working with the Kusama network?
Do you need a “bridge” such as web3 to connect the dapp with the Centrifuge network?

Welcome,
It might be a bit confusing but Centrifuge started as a dApp (Tinlake) on Ethereum, here is the outdated white paper: [https://centrifuge.io/centrifuge\_os\_white\_paper.pdf](https://centrifuge.io/centrifuge_os_white_paper.pdf)
Here is an updated token summary of Centrifuge chain built on substrate: [https://centrifuge.io/cfg\_token\_summary.pdf](https://centrifuge.io/cfg_token_summary.pdf)
Centrifuge will never work with Kusama but Altair will:
> **[Centrifuge: Real World DeFi](https://centrifuge.io/altair/)**
>
> Decentralized asset finance: asset Originators can access bankless liquidity, and investors can earn attractive yields from an open marketplace of asset pools.
