Miners build SHA-256 blocks and must include the reward outputs required by current network policy. Avalanche-enabled nodes create signed Stake Proofs over mature XEC UTXOs, poll peers and weight responses by proven stake. Each eligible staking output must be a Pay To Public Key Hash (P2PKH) UTXO, which assigns spending control to a public-key hash, containing at least 100,000,000 XEC with at least 2,016 confirmations. One Stake Proof may include several eligible UTXOs; the minimum applies to each output. The coins do not move into a custody contract, and the current guide says there is no lock or slashing, but the operator must keep a compatible node online.
Post-Consensus and Pre-Consensus solve different moments. The former finalizes the mined chain and resists reorgs; the latter gives sub-block transaction confidence. Current block allocation is 58% to miners, 16% to protocol development, 16% to the Global Network Council for ecosystem development and 10% to Avalanche stakers. Those shares and recipients are policy maintained through node software and network adoption, not an immutable coupon owed to every XEC holder.
