📒 Hardware Acceleration: Nexa Node on an FPGA
In the last article we met Blitz, the card that takes signature checking off the CPU. We closed with a bigger question: what happens when you put the whole node inside an FPGA?
We don’t like running a node on our main desktop machine, especially when it is bogging down all cores, the fans are blazing and the office is heating up. We want to run it on a tiny little node that we plug into the router and just SSH into when we need to.
That is the long game of this series: building a microchip for cryptocurrency, a microchip that can do the same thing as your software node, but is faster, more reliable, uses less energy, and can be built for a fraction of the cost.
That chip is still ahead of us, but there are a lot of useful things we can do directly in hardware in the meantime.

📒 Monthly Development Updates: September 2026
Over the past month and into this month, development has moved forward across the Nexa ecosystem. Most activity and effort focused on our Rostrum indexer, which we're updating and improving. We put a lot of effort into achieving much faster synchronization and quicker network notifications.
On the full node side, the Tailstorm protocol keeps getting tougher and is being extensively tested. We’ve already released detailed updates on the ongoing work and improvements, and you’ll find a recap there.
NexScript also hasn't been forgotten and is receiving updates. It’s 1.2.0-beta. Version 1.2.0-beta gives smart contracts new tools for working with token authorities, and the playground will receive updates that refresh it to a modern platform look.
Wally, the explorer, and our developer libraries also received a long list of improvements, many of them lined up for upcoming releases.
Find more details on these and other important developments from Nexa in the Monthly Development Update below. 👇

📒 Beat Peter’s FPGA: The BRAM-ring Bounty
On 6 October 2026, Peter Rizun (@PeterRizun) announced a bounty on X with a 0.2 BTC prize pool (around $16,000) for anyone who can beat the FPGA’s efficiency.
The main prize is 0.1 BTC, with smaller prizes for smaller achievements, and the bounty is open until 4 November 2026, 23:59 Pacific Time.
Peter designed a BRAM-ring proof-of-work function on a cheap Efinix Tz170 FPGA and ran it at 37,100 H/s. So far, the best GPU result is 1,493 H/s on a $499 RTX 3070.
Measured in hash rate per dollar of hardware, the FPGA is more than 100x more efficient.
The claim is that no GPU, CPU, NPU or other off-the-shelf hardware can close the gap, and the bounty is for anyone who proves otherwise.

📒 Tailstorm: Hardening the Protocol
Tailstorm replaces single 2-minute blocks with a DAG of subblocks that are tied together by a summary block, while keeping the 2-minute settlement cadence.
The code already ships inside Full Node 2.2.0.0 and stays dormant until the second hard fork is activated.
Since that release our developers have been working on closing gaps in the consensus checks, making fork comparison more accurate, and building tests that put Tailstorm through the situations a live network will throw at it.
This article walks you through the improvements and refinements made in the past weeks. 👇

All of this long path wasn't necessary, and @BitcoinUnlimit was right all along.
On-chain scalability and programmability were always possible with the original UTXO model and source code.
Nexa is the endgame and is already proving that with all its releases. 💯

Very impressive results 👏 You have a whole month and a @claudeai to beat FPGA and claim the 0.1 $BTC bounty. Could you?
My little $40 FPGA can beat your big bad GPU. Prove me wrong and win 0.1 BTC.
I designed a proof-of-work called BRAM-ring. A $40 Efinix Tz170 does 37,100 H/s on it. The best anyone has managed on a GPU is 1,493 H/s, on a $499 RTX 3070. Per dollar the little chip wins by more than 100×, and I don't think any GPU, CPU, NPU or other off-the-shelf hardware can close that gap.
The bounty:
• 0.1 BTC to the first person who shows non-FPGA hardware at or above 371 H/s per dollar
• 0.01 BTC every time someone beats my GPU or CPU kernel by 10% (bit-exact, measured on my machine, the bar ratchets)
• 0.01 BTC for a real shortcut in the function: half the work per hash, counted not timed
How to claim: reply to this tweet with the full 40-character git commit hash of your code and the prize you're claiming. Your code can stay private until the deadline; the hash fixes your place in line.
Deadline: 4 November 2026, 23:59 Pacific.
Rules: git.nodelabs.ca/nexapow/bram…
Code (make prove checks C, AVX2, CUDA and Verilog against the same 8 vectors): git.nodelabs.ca/nexapow/bram…
Prize pool 0.2 BTC, held at bc1qtk8q5nsupm47kg5vz9turqacx8lg2whvxukpuj. Signed proof of funds in the first reply and in BOUNTY.md.

How ridiculous is it that, after realizing the account model can't scale, Ethereum wants to get back to the UTXO model?
What about doing it right from the very beginning and avoiding all this mess?

🧧 New Release: Otoplo Wallet 5.3.0
We’re excited to share that Otoplo Wallet 5.3.0 is now available. This update adds a new option to refresh vault balances and is ready for desktop and mobile platforms.
While vaults have been part of Otoplo since its inception, they lacked some functionality in rare cases. These gaps are now filled, and one of the newest features lets users refresh their vault balances if they are missing.
