About Testnet T0
The first testnet of Doge Protocol, codenamed as T0 was released on Feb 22, 2022. This blockchain is quantum resistant and uses clique consensus. Falcon 512, a third round candidate for NIST post quantum digital signatures is used to secure accounts in this testnet. Inter-node communication is secured using NTRU HRSS. Doge Protocol is the first if not one of the first to secure both accounts and inter-node communications using quantum resistant cryptography.
The inter-node communication uses a hybrid model, in which the final client and server encryption keys are derived similar to TLS as detailed in RFC 8446. NTRU HRSS is used for key exchange and the key material thus derived is used as input to HMAC HKDF functions (RFC 5869). However unlike TLS, instead of trusting the certificate, the key of the other node is instead trusted. The private key corresponds to the Falcon key-pair used to secure the account using digital signatures.
This blockchain is build on Ethereum code-base, hence most of the Ethereum APIs and functionality are available in this blockchain.
