Polkadot is a next generation blockchain protocol that greatly simplifies cross-chain communication, limitless scalability, and interoperability by bringing multiple blockchains protocols into one network.
CryptoArena is a layer 2 solution and choses Polkadot Relay Chain as its layer 1 infrastructure


Kusama is a scalable network of specialized blockchains built using Substrate and nearly the same codebase as Polkadot. The network is an experimental development environment for teams who want to move fast and innovate on Kusama or prepare for deployment on Polkadot.


Substrate by Parity Technologies is a modular framework that enables you to create purpose-built blockchains by composing custom or pre-built components. Substrate makes building a blockchain far faster, easier, and safer than ever before.
CryptoArena's blockchains will be deployed through Substrate, thus will be natively compatible with Polkadot and Kusama.


Zenroom by Dyne is a small, efficient and secure execution environment for deterministic cryptographic proofs using Zencode, a plain English language DSL smart contract language.
