Launching a chain is easy.
Securing one is not. In 100 days, BTX built a 22 MH/s wall.
The graveyard of crypto is full of young chains that never attracted enough honest hashrate to defend themselves — networks that stayed cheap to attack and quietly died. BTX did the opposite. In roughly 100 days, the network went from a single-miner genesis to a ~22 MH/s GPU-defended chain — and it did so on a MatMul proof-of-work design most teams wouldn't have dared to ship.
This is the story of that achievement — and why the numbers behind it represent real, hard-won security. Every figure here came straight from the BTX mainnet chain at block 138,283: measured, not marketed.

Every “hash” is a full matrix-multiply. That changes everything.
BTX does not run SHA-256. The team built the network on a MatMul proof-of-work: every unit of hashrate is a full matrix-multiplication candidate solve (mainnet shape n=512, b=16, r=8). That is a deliberate, defensible choice.
ASIC-resistant by construction.MatMul PoW maps to general-purpose GPU silicon, not cheap fixed-function ASICs. That keeps mining open to the community and keeps the security budget honest — an attacker can't simply tape out custom hardware to overwhelm the chain.
Every hash is expensive. A single BTX H/s costs vastly more compute than a SHA-256 hash. So when BTX reports ~22 MH/s, that is ~22 million genuine matrix-solves per second — an enormous, tangible wall of real silicon between the chain and anyone who would attack it.
Getting a novel PoW to be parity-correct, stable, and consensus-clean across CPU, Apple Metal, and experimental CUDA backends is serious engineering. The validation work — zero digest mismatches and zero backend fallbacks across hundreds of millions of nonces in sustained testing — is the unglamorous foundation that makes everything below trustworthy.
- ✓MatMul proof-of-work — every hash is a full 512×512 matrix-multiply candidate solve.
- ✓ASIC-resistant by construction — maps to general-purpose GPUs, not fixed-function silicon.
- ✓Parity-clean across CPU, Apple Metal, and experimental CUDA backends.
- ✓Defended by a large, fast-growing fleet of honest GPUs.
- ✓A clean live upgrade at block 125,000 — no consensus incident.
- ✓Every security number verifiable straight from the chain.
- ✕Not a SHA-256 fork — BTX hashrate is not comparable to SHA-256 hashrate.
- ✕Not ASIC-defendable cheaply — no tape-out shortcut for an attacker.
- ✕Not a marketing claim — figures are measured, not modelled.
- ✕Not stalling — hashrate has been roughly doubling weekly through June.
Five-million-fold growth in defensive power, in about 97 days.
In about 97 days — genesis on 23 March 2026 to block 138,283 on 28 June 2026 — BTX network hashrate grew from a ~4.4 H/s launch floor to ~21.9 MH/s:
- →~5,000,000× growth in network defensive power.
- →~790,000,000× increase in difficulty, from the protocol floor to
0.458. - →A chain now orders of magnitude more expensive to attack than it was even a month ago — and getting harder every week.
Each of those multiples is a security milestone. A 51% attack on BTX today means out-running a large and rapidly growing fleet of GPUs. A month ago it meant out-running a handful of machines. The team closed that gap astonishingly fast.

A flawless upgrade, a real GPU stack, and security that compounds.
A flawless protocol upgrade at block 125,000
Most young chains fear hard upgrades — a botched activation can split the network. The BTX team shipped the MatMul nonce-seed v2 rules at block 125,000 cleanly, on a live mainnet, with no consensus incident. The chain didn't just survive the upgrade — it accelerated through it: hashrate went 6.2 → 12.2 → 18.7 → 21.9 MH/s in the three weeks after, roughly doubling every week. That is what a well-engineered upgrade looks like — invisible to users, and a launchpad for growth.
A GPU mining stack that actually works
The hashrate inflection in mid-May — a ~9× jump in eleven days — only happened because the team had done the hard work to make GPU mining real and correct on BTX. Tuned Metal kernels for Apple Silicon, a parity-clean experimental CUDA backend validated on datacenter cards, share-validation tooling proven against real mainnet blocks: this is the infrastructure that let serious hashrate come online and stay online without ever threatening consensus.
Security that compounds
The team designed the economics so that defending the chain is rewarding. A predictable 20 BTX subsidy every ~90 seconds turned BTX into one of the most attractive young chains to mine — and every miner who showed up to earn it added permanent defensive weight. The result is a virtuous cycle the team engineered on purpose: rewards attract hashrate, hashrate hardens the chain, a harder chain is worth more to defend.
From defenseless to formidable — a novel PoW, shipped correctly.
From defenseless to formidable in 100 days. Five-million-fold growth in hashrate is not luck; it's the payoff of a credible PoW, working multi-platform miners, and clean operations.
A novel PoW, shipped correctly. Building MatMul proof-of-work — and proving it parity-correct across CPU, Metal, and CUDA — is far harder than forking an existing SHA-256 chain. The team chose the hard, ASIC-resistant path and made it work.
A live upgrade without a scratch. The block-125,000 activation is the kind of thing that breaks lesser projects. BTX made it a non-event.
Security you can verify.Every number here came straight from the chain. The team's defense isn't a claim in a whitepaper — it's measurable, on mainnet, today.
From “new chain” to “seriously defended network.”
At ~22 MH/s and climbing, BTX has crossed from “new chain” to “seriously defended network.” The same design that drove this ramp — open GPU mining, honest rewards, disciplined engineering — is what will carry it forward. The team has built a foundation that gets stronger with every block.
For a chain just over three months old, that is a remarkable piece of work.
BTX security & hashrate — questions
- How much did BTX network hashrate grow in its first 100 days?
- From a ~4.4 H/s launch floor at genesis (23 March 2026) to ~21.9 MH/s at block 138,283 on 28 June 2026 — roughly five-million-fold growth in the network's defensive power over about 97 days. Difficulty rose ~790,000,000× over the same period, from the protocol floor to 0.458.
- Why is a BTX hash worth more than a SHA-256 hash?
- BTX does not run SHA-256. Every unit of BTX hashrate is a full matrix-multiplication candidate solve (mainnet shape n=512, b=16, r=8). A single BTX H/s costs vastly more compute than a SHA-256 hash, so ~22 MH/s represents ~22 million genuine matrix-solves per second. BTX hashrate is therefore not directly comparable to SHA-256 hashrate.
- Why does MatMul proof-of-work make BTX harder to attack?
- MatMul PoW maps to general-purpose GPU silicon rather than cheap fixed-function ASICs, so it is ASIC-resistant by construction. An attacker cannot simply tape out custom hardware to overwhelm the chain — they must out-run a large, growing fleet of GPUs. That keeps mining open to the community and keeps the security budget honest.
- What happened at block 125,000?
- BTX shipped the MatMul nonce-seed v2 rules cleanly on a live mainnet with no consensus incident. The chain accelerated through the upgrade — hashrate went 6.2 → 12.2 → 18.7 → 21.9 MH/s in the three weeks after, roughly doubling every week.
- How were these security figures measured?
- Every figure is derived directly from the BTX mainnet chain — getnetworkhashps 120 <height> and getblockheader on a fully-synced node at height 138,283. The block index (difficulty, timestamps, cumulative work) is retained even on a pruned node, so historical hashrate is computable across the full chain. The 120-block window smooths short-term variance.
- Is the chain still getting more secure?
- Yes. At ~22 MH/s and climbing, hashrate has been roughly doubling on a weekly cadence through June. A predictable 20 BTX subsidy every ~90 seconds keeps attracting honest hashrate, and every miner who shows up to earn it adds permanent defensive weight to the chain.

Hashrate and difficulty figures are derived from BTX mainnet chain data as of block 138,283 and the 120-block smoothing window; individual points are order-of-magnitude and may be revised as the chain advances. A 51% attack remains possible against any proof-of-work chain; growing honest hashrate raises its cost but does not eliminate it. Mining outcomes depend on hardware, difficulty, and market conditions, and are not guaranteed.
