X1 is going to permanently burn 85,000,000 XNT as a tribute to Solana's Alpenglow upgrade. X1 Labs CEO Jack Levin announced it on X on the evening of October 21, a few hours after Alpenglow went live on Solana mainnet. The number is not random: Alpenglow cuts Solana's target finality from about 12.8 seconds to about 150 milliseconds, roughly an 85x improvement.
The burn has not happened yet. We are waiting for the transaction and will add the hash here as soon as it lands on chain.
The announcement
Levin posted on X:
“A nod to where it all began. Today, Solana activated Alpenglow - bringing target finality from roughly 12.8 seconds to ~150 milliseconds. That's about an 85× improvement. X1 was born from Solana's technology, so we thought 85 was a pretty good number to celebrate. 85,000,000 XNT - PERMANENTLY BURNED. A small tribute to a massive technical achievement.”
He congratulated Solana co-founder Anatoly Yakovenko (@toly) and everyone who helped push Alpenglow across the finish line, and signed off: “From Solana's roots to X1's future - keep building.”
Asked on Telegram how the burn would be done, Levin answered: “Will be burned by sending them to incinerator address”.
How the incinerator works
X1 runs on the Solana Virtual Machine, and it inherits Solana's incinerator: the address 1nc1nerator11111111111111111111111111111111. Nobody holds a key for it. Any native balance sent there is destroyed by the validator software at the end of the block and subtracted from the chain's total supply, so the address itself always reads zero. We checked it on X1 mainnet on October 22 and it holds 0 XNT, as expected.
That makes the burn easy to verify once it happens. The transaction will show 85,000,000 XNT moving to the incinerator, and the network's total supply, which anyone can read with the standard getSupply RPC call, will drop by the same amount.
What 85 million XNT means for supply
We read X1 mainnet's supply directly on October 22. Total supply is 1,080,909,939 XNT. Taking 85,000,000 out of that:
| Before the burn | After the burn | |
|---|---|---|
| Total supply | 1,080,909,939 XNT | 995,909,939 XNT |
| Share of supply burned | - | 7.86% |
| A holder with 1% of supply | 1.000% | 1.085% |
| FDV at $0.1808 | $195.5M | $180.1M |
Three things stand out. Total supply falls below one billion XNT for the first time. The burn is 7.86% of supply, which is Levin's “roughly 8%”. And every other holder's slice of the total supply grows by about 8.5%. Levin's example puts it at 1.08%; the exact figure is about 1.085%. If you held 1% of supply before, you hold about 1.085% after, without buying anything. Your balance stays the same; there is simply less XNT in existence.
The burn itself does not change the price. At the same price, fully diluted value (FDV) falls by the value of the coins destroyed, from about $195.5M to $180.1M. Live price, market cap and FDV are on our XNT price page.
Thousands of years of fee burning in one transaction
Like Solana, X1 burns part of every transaction fee. To see how much that adds up to, we read X1's total supply at the start and end of two separate 120-second windows. In one, the network burned about 0.053 XNT; in the other, 0.034 XNT. Annualized, that is roughly 8,900 to 14,000 XNT a year, worth about $1,600 to $2,500 at today's price of $0.1806.
At that pace, the 85 million XNT burn equals somewhere between 6,064 and 9,500 years of X1's normal on-chain fee burning, done in a single transaction.
Bigger than any BNB burn
BNB is the best-known token with a regular burn. Its largest single burn by token count was in January 2021, when Binance destroyed 3,691,888 BNB, about 2.2% of the supply at the time. The latest quarterly burn, the 37th on October 19, 2026, removed 1,646,196 BNB, about 1.2% of supply. It was worth about $1.2 billion, far more in dollars than this burn, but much smaller as a share of supply.
At 7.86% of total supply, X1's burn is more than three times BNB's biggest one as a share of supply. If it goes through, it will be a larger one-time cut to supply than BNB has ever made.
Where will the XNT come from?
Levin did not say which wallet will send the 85 million, and that decides how the market cap moves. Most XNT is not in circulation. On October 22, 1.04 billion XNT, or 96.1% of supply, was classed as non-circulating: the X1 Foundation treasury (46.4%), the delegation program (31.5%) and the X1 Labs treasury (17.0%). Circulating supply was 42.4 million XNT, or 3.9%, giving a market cap of about $7.7M against an FDV of about $195.5M.
If the 85 million comes from a treasury, as the size suggests, circulating supply and market cap stay the same and only total supply and FDV shrink. Circulating XNT would then be 4.3% of the new total instead of 3.9%. That is our reading of the numbers. The source wallet has not been announced, and we will confirm it from the transaction.
Staking is unaffected
The burn does not touch anyone's wallet or stake account. Staked XNT keeps earning as before, and stakers' share of the total supply rises with everyone else's. To start staking, or to compare validators, see our X1 staking guide.
Alpenglow: what Solana switched on
According to Solana's upgrade page, Alpenglow activated in epoch 1064, which began on Wednesday, October 21, 2026, at about 13:36 UTC. The cluster kept running TowerBFT, the consensus Solana had used since launch, for the first 5,000 slots (about 18 minutes), then switched to Alpenglow from slot 459,653,000. The handoff took about 900 milliseconds.
The part now live is Votor, Alpenglow's new voting protocol, which shipped in Agave 4.3. Under TowerBFT, finality took about 12.8 seconds. Votor targets about 150 milliseconds, and 12.8 divided by 0.15 is where the 85 comes from. Validators no longer put vote transactions in blocks: votes are exchanged directly and combined into certificates. That means Solana's reported transaction count will drop even if real usage doesn't. Rotor, the second half of Alpenglow, which changes how blocks spread across the network, is planned for a later release and is not yet scheduled.
Each voting Solana validator now also pays a flat Validator Admission Ticket of 0.8 SOL per epoch from its vote account.
Where X1 stands
X1 shares the roots Levin is celebrating. Its validator client, Tachyon, is built from Solana's codebase, and X1 still runs TowerBFT consensus today. X1 has not announced whether or when Tachyon will adopt Alpenglow. For now the 85 million XNT is a thank-you to Solana, not a roadmap item.
We will update this article with the transaction hash and the new total supply once the burn is confirmed on chain.
