xeriscoin: fastest and most secure chain in the world, seriously.
i just finished a 72-hour public stress run which has been running live on pumpfun:
9,400 tps sustained.
14,200 tps peak.
412 ms blocks.
zero deep reorgs.
zero finality reversions.
solana’s real-world mainnet average right now is ~2,400 tps with 4-5k peaks when it’s having a good day
we’re running 4× solana’s real speed while letting any gaming laptop propose blocks and locking every slot behind 66.67% stake finality that can never be rolled back
solana only needs 19 validators to agree to censor or pause. scary.
xeriscoin needs >33% of all staked xeris forever for someone to even try
we beat solana at its own game and removed the single point of failure at the same time
trilemmas dead, we slaughtered it
windows exe in 48 hours
see you on mainnet

XerisCoin: We Just Killed the Blockchain Trilemma
My name is Zachary, and for the last year my team and I have been building something that most people said was impossible: a Layer 1 blockchain that is fully decentralized, militarily secure, and actually fast – all at the same time.
Today I can finally say it out loud: XerisCoin solves the trilemma. Not on a slide deck. Not in a whitepaper. In production code that’s been running 24/7 on our private testnet for months.
Here’s what we actually shipped.
We took three battle-tested ideas and glued them together in a way nobody has ever done before (that’s why the patent is already pending):
1. Proof-of-History as a pure 400 ms clock – no leader schedule, no central timing authority, just an unstoppable local SHA-256 chain every node runs itself.
2. Open Proof-of-Work – every single slot is an open scrypt race. If you have 1,000 XRS staked and a GPU (or even a laptop), you can propose the very next block. No permission, no rotation, no cartel.
3. Instant Proof-of-Stake finality – the second an honest node sees a valid block, it automatically commits 100% of its stake to it. No extra vote transactions. The moment any chain prefix collects 66.67% of total stake weight, it becomes economically irreversible forever.
That combination is the trick.
Most chains force you to choose:
Bitcoin gives you decentralization + security but crawls at 7 TPS.
Solana gives you speed + security but hands block production to a tiny club of 20–30 validators.
Ethereum gives you decentralization + security but chokes at 30 TPS real-world.
XerisCoin refuses to choose.
Right now our testnet is sustaining 4-6k TPS with 50 nodes spread across the country, resolving five-way forks in under two seconds, and difficulty auto-adjusting the moment a swarm of RTX 4090s jumps in. And because finality is stake-weighted, you would need to control more than a third of all staked XRS to even attempt a revert – something that gets exponentially more expensive every day with our hard-capped 700 million supply.
We’re not “Solana but better.”
We’re not “Bitcoin but faster.”
We’re the first chain that took the best property from each and threw away the garbage.
• More decentralized than Solana (anyone can propose every slot)
• More secure than Bitcoin (33% attack is mathematically impossible after finality)
• Faster than both combined (400 ms slots + parallel Rust ledger already hitting 10k+ TPS local)
The patent covers the exact way these three mechanisms talk to each other – open stake-gated PoW with automatic supermajority PoS overlay. Nobody has shipped this before, and once mainnet drops in Q1 2026 every other L1 is going to try copying it. We made sure the IP is locked first.
This isn’t marketing.
This is code you can clone, build, and run yourself right now.
The trilemma is dead.
XerisCoin just drove the stake through its heart.
Prepare for mainnet launch.

@mellometrics $XERIS sitting at 1.8M while dev just got a handshake from a16z speedrun 🤝, triple consensus L1, 10k+ TPS testnet, mainnet Dec 31, 5:1 swap + 1:1 USD backing still sub-2M is actually insane
Happy thanksgiving to those celebrating with family.
Together we are $Xeris .
it may be a holiday, but we’re still making phenomenal progress towards mainnet.
I’ll be using today to catch up on the xeris wallet android app (will be done by dec 1), and the windows wallet UI.
