In the latest big update, I've completely replaced the previous block producer selection mechanism (QRDS) with Dilithium3-VRF - a verifiable random function based on post-quantum cryptography, NIST FIPS 204 (ML-DSA-65). What this means in practice: Previously, producer selection was deterministic - all nodes computed the same hash function from public data, and the result was predictable in advance. This created an attack vector: knowing the future producer, an adversary could target them before block creation. Now each node privately evaluates a VRF using its secret key and a shared seed value. The result is unpredictable to everyone else, yet cryptographically verifiable - any network participant can confirm that the node genuinely had the right to produce the block, without knowing its private key. The winner is determined by the lowest VRF output among all claims, making result manipulation impossible. In parallel, I'm working on the node activation mechanism. The key security requirement: the activation code is cryptographically bound to the wallet address that received it. This means that even if the code is intercepted, it cannot be used from a different wallet - during server-side activation, an XOR-encrypted binding between the code and the address is verified. The owner's mnemonic phrase is the only way to confirm the right to launch a node.
