A market-funded second subsidy for Bitcoin — $NAT.

No. Merged mining means pointing hashpower at a second proof-of-work chain. NAT has no second chain — the reward is decoded from each Bitcoin block's own bits field and credited to that block's coinbase address by an open TAP Protocol indexer. The miner does nothing extra and runs nothing new.

No. There is no soft fork, hard fork, or BIP. Bitcoin's consensus rules are untouched and Bitcoin nodes are entirely unaware of NAT. It is an off-chain accounting layer (a meta-protocol) that interprets data already on Bitcoin.

No. The NAT credit is computed automatically from each block's header and assigned to the coinbase address that mined it. There is no opt-in, no claim transaction, and no software to install. A miner can ignore NAT entirely and still accrue it.

Open any recent block on mempool.space or another explorer and read its bits field. Decode it as an integer using NAT = s×2²⁴ + c (with s the high byte and c the remaining value). Today that yields ~386,021,021 NAT — constant this difficulty epoch (blocks 957,600–959,615) and resetting at block 959,616 (≈ Jul 26), so re-read it after each retarget. The amount drifts up only slowly (~1.3%/yr) as difficulty rises — it never halves. Crediting began at block 885,588.

No oracle — and the indexer is checkable. The NAT credit is a deterministic read of data already on Bitcoin: take any block's bits field, apply the formula, and you have the amount; the block's own coinbase address is the owner. An open TAP Protocol indexer computes this off-chain, and anyone can run their own and get byte-identical results. Nothing is fed in from outside — no price feed, no committee, no API you have to trust. Don't take our word for it: run the decode yourself (see "How it works" above).

There is no switch in the emission rule. The credit is math on public block data — every block's amount and owner follow from the block itself, and anyone can compute it independently. Since the miner-redirect went live at block 885,588 it has credited every block with no human intervention. There was also no insider supply to dump: no presale, no VC tranche, no team allocation (see the premine question below). The honest caveat: NAT still depends on people continuing to run indexers and a market continuing to care — that's an adoption risk, not a switch.

The issuance is real — the "printer" isn't. Arbitrary issuance means someone decides when and how much. NAT's issuance is a formula: each block's amount is read from Bitcoin's own bits field. No vote can change it, no team can print it, and it actually drifts down about 1.3% a year as difficulty rises — it never halves, but it never spikes either. Whether the market absorbs a perpetual, formula-driven supply is the real question — that's a demand question, owned honestly in the risks above, not a discretionary-printing question.

Because difficulty rises. The per-block amount is decoded from the bits field — Bitcoin's difficulty target. As the network gets stronger the target tightens, and the decoded amount drifts down — about 1.3% a year historically, resetting at each two-week retarget. A stronger network → a smaller number, by formula. That's the opposite of an emissions committee: nobody chooses it, and you can verify every step from public block data. (It also never halves — the drift is gentle, not a cliff.)

No premine — an open mint. NAT began as a first-come public mint in November 2023 (block 817,709): no presale, no VC tranche, no team allocation, no vesting cliffs — there is no insider supply waiting to unlock, because there were no insiders. Since block 885,588 (Feb 2025), every block's NAT goes to the miner of that block. The difference between a premine and an early adopter is whether the rule was the same for everyone. Here it was — and the chain is public, so you can check.

It keeps the meme energy — and adds what memecoins lack. A memecoin has exactly one source of demand: attention. When attention fades, the bid fades. NAT has that layer too — fair mint, a mascot, three years of culture — but stacks two more underneath: it is paid to the miners securing Bitcoin, every block, and its issuance is a formula read from Bitcoin's own headers, not a decision. Culture is the megaphone — not the foundation. Whether the market keeps valuing those layers is not guaranteed; see the risks above.

One difference: who gets paid. Most meta-protocol tokens mint to whoever clicks fastest — collectors, snipers, whoever was watching the mempool that day. NAT is credited to block-winners only: the miner who actually secured the chain earns it, every block, automatically. That makes it the only meta-token whose distribution is itself a payment for Bitcoin's security. Everything else — indexing on TAP, living on Bitcoin L1 — it shares with its peers. The claim isn't that NAT is better tech; it's that it does a different job.

Miners selling is the mechanism, not a flaw. Miners always sell what they mine — gold miners sell gold, Bitcoin miners sell BTC — that's how a mined asset reaches the market, and in NAT's case selling is precisely how the reward becomes revenue that funds security. The buy side is whoever values what NAT is: a claim tied to funding Bitcoin's security budget, held the way a market holds gold rather than consumed like fuel. Some pools sell on sight; some hold. Whether that demand proves durable is the open question — the honest answer is that only a full cycle will show it.

Paying the people who secure Bitcoin is the point. In proof-of-work, security is never free — someone funds it, and today that is overwhelmingly the halving block subsidy. NAT's proposed demand is monetary: you hold it the way a market holds gold — a focal asset tied to funding Bitcoin's security — you don't consume it like gas. That is infrastructure utility, the same category Bitcoin's own value lives in, not app utility. Whether that demand proves durable is the open question — the market decides, and we make no guarantee.

Same printer, opposite machine. A staking yield pays the token to holders of the token — the emission loops back into itself and funds nothing outside the system. NAT's emission is paid to miners for real, external work: hashrate, hardware, energy — the things that actually secure Bitcoin. Staking pays you to hold. NAT pays for security. And unlike stake-based systems, where attacking means simply buying more of the token, the security NAT supports stays exogenous — energy and physics, not balance sheets.

The emission is structural; buyers aren't — and we say so. That framing cuts both ways. NAT doesn't need perpetual new believers to function mechanically — the credit happens every block regardless — but its security contribution is only as real as the demand behind it. What it doesn't have is the classic exit-liquidity structure: no insider allocation waiting to unlock, and the miners who receive it get it at zero marginal cost, every block. The test that matters is durable adoption and turnover across a full cycle — see "What would prove this wrong?" below.

No — and the direction of the dependence matters. NAT is read out of Bitcoin; nothing was added to Bitcoin, so it cannot be harmed by NAT existing, and it would keep operating unchanged if NAT disappeared tomorrow. What the protocol guarantees on its own is liveness — blocks keep coming as miners leave and difficulty adjusts — not an optimal level of security. The security budget is already funded by markets outside the protocol. NAT is one market-funded supplement to that budget — a bounded supplement, not a dependency and not a fix.

Because the comparison that matters is per unit of value — and it's protocol math. Ask: for every unit of market value, how much block security does an asset fund? The price sits on both sides of that fraction, so it cancels. What's left is issuance over supply, set by protocol. On that measure NAT already funds about six times more security per unit of market value than Bitcoin does today — and the gap widens every halving, because one emission halves and the other doesn't. Today's absolute share is small, and we say so. The argument is the direction, not the level.

It's an open question — and we present it that way. The facts: Bitcoin's security spend is dominated by a subsidy that halves every four years toward ~0 by ~2140, and fees today are a small, volatile fraction of the reward. Serious people disagree about whether fees grow into the gap: optimists point to scarce blockspace and a century of adjustment time; the concern side notes that a fee-only chain is theoretically less stable and that "the market will provide" is a hope, not a mechanism. This page's position: unresolved and worth hedging — not a settled disaster. Anyone claiming certainty in either direction is selling something.

That's exactly what the board above grades. The short version: a tail emission funds security by printing new BTC forever — it breaks the 21M cap and needs a fork, politically the least likely change in Bitcoin. Higher fees are the status-quo bet: nothing changes, but fees currently cover a small fraction of the reward, and "fees will grow" is a hope with no fallback. NAT's lane is narrower than either — nothing about Bitcoin changes, and the funding is whatever a market volunteers. The full board (link above) grades every option on six non-negotiables.

Not to Bitcoin — repeatedly to smaller chains. Bitcoin has never suffered a successful 51% double-spend: the budget defending it has always out-priced the attack. Chains with thin security budgets are a different story — Ethereum Classic and Bitcoin Gold were both reorged by rented hashpower, and in August 2025 rented hashrate pushed past half of Monero and reorged six blocks. No exploit, no bug: the defense budget was simply smaller than the attacker's wallet. That's why the size of the budget — not just the elegance of the protocol — is the security.

A lone buyer: close to impossible. A coordinated actor: the realistic version. For an individual, ASIC output is capped and spoken for, deployment takes datacenters and years, the network grows while you buy — and honest mining with that much hardware pays better than crashing your own holdings. Coordinated or state actors change the math: rented hashrate, acquired pools, and political rather than financial motives. That's the version that has actually happened to smaller chains (see above). Raising what miners earn raises the budget any attacker must out-spend — that is NAT's entire argument here, and it only holds to the extent the market values NAT.

By raising the revenue an attacker must out-spend — at the margin. The cost of attacking a proof-of-work chain tracks what its honest miners earn: out-spending them is the attack. Security is bought at the margin — the miners closest to shutting down are the hashrate the network loses first, and a second income stream matters most, proportionally, exactly there. More miner revenue → more surviving hashrate → a more expensive attack. The honest asterisk: NAT's contribution is proportional to its market price, which is reflexive — it can be smallest when needed most. That risk is owned above, not hidden.

The creators are doxxed, not anonymous: Will and Iman (TheBlockRunner), working with the Digital Matter Theory framing, and BennyTheDev (the developer behind TAP Protocol), which is the indexing layer NAT is built on.

A fair question every experiment should answer. The falsification test: years of flat pool adoption and dead market turnover — an emission with no one on the other side. If the second subsidy can't attract durable demand across a full cycle, the thesis fails, and this page will say so. What would not disprove it: price swings in either direction — the mechanism is measured in adoption and hashrate, not in a chart.

No. This page is an explainer, not advice. There are no price targets, no projections, and nothing here is a recommendation to buy, sell, or hold anything. NAT is an experiment; it could fail. Do your own research and verify every claim independently.
