    <h3>direct coinbase payouts</h3>
    <p>Rewards are split <b>inside the winning block</b>, proportional to a
    published window of recent shares. Paid the moment the block exists.</p>
  </div>
  <div class="specrow">
    <h3>your own templates</h3>
    <p>Miners build blocks from <b>their own nodes</b> — the pool publishes the
    required payout split and verifies it, but never chooses your transactions.</p>
  </div>
  <div class="specrow">
    <h3>transparent scoreboard</h3>
    <p>An append-only share ledger with the split snapshot stored for every
    block. <b>Anyone can recompute every payout</b> from public data.</p>
  </div>
  <div class="specrow">
    <h3>two implementations</h3>
    <p>A Python reference and a production Java port, wire-compatible, pinned to
    each other by golden test vectors. <b>One protocol, no lock-in.</b></p>

<section>
  <div class="eyebrow">the fork's own answer to pool trust</div>
  <p style="max-width:640px">The fork as shipped bakes a pool mechanism into
  consensus itself: a secret <span class="mono">xor_key</span> held by the pool
  masks the block hash, so a miner can verify its own shares but
  <b>cannot tell a share from a winning block</b> — only the key-holder can,
  which defeats block-withholding attacks. This reference implementation
  predates that design and implements the published-claims TIDES model;
  the two are complementary reading for anyone building a real pool for
  this chain.</p>
