Building DeFi & blockchain ecosystem apps, advanced UTXO smart contracts, and AI developer tools on NEXA

[David T @DPTib]

Looking for a blockchain to build on? nexacoin:native is the place to start. @NexaMoney makes it easier and gives you more functionality than bitcoin:native & bitcoin-cash:native, with a UTXO model that provides more safety than ethereum:native.

It’s the obvious choice

📒 Build on Nexa: AI-Assisted Development with David Thibodeau

Today the Nexa team wants to introduce you to a couple of tools we have created for our community to assist you with building applications on Nexa.

We know that some of you may be experienced developers, while others may be brand new to building apps.

One of our tools is specifically designed to empower some of our less technical users and make this process easier for all of you, through the use of Nexa AI-Assisted Development tools and AI skills.

In this short guide David Thibodeau (@DPTib) will walk you through a quick setup process and explain the basics of AI skills and how to use them.

After this guide you will be ready to build a fully functional Nexa application just from a single prompt. Let's get started. 👇

[David T @DPTib]

@lenntreve Glad you’re finding it helpful! Careful now - you may end up finding it hard to step away from your screen as you start to turn all of those ideas you’ve been brainstorming into working code 😅

[David T @DPTib]

@lenntreve @NexaMoney I knew you’d put these skills to good use, Lenn 💪👏

[David T @DPTib]

Love to see it 👏
People taking the initiative to build. Start small, grow your ideas, and learn during the process. Things that you thought weren’t possible 6mos or a year ago are now within your reach. nexacoin:native gives you the tools - regardless of your technical level!

[Lenn Treve @lenntreve]

I built my first app with Nexa AI. It lets you send payment requests and check their status.

It’s currently running locally, but the idea is to let you share a link via email, WhatsApp, etc.

My first dApp! No coding skills at all 😁

(In the demo, only the transaction fees are deducted because I’m making a payment to myself.)

@Luisenriquepl @lenntreve Pt3… which satisfies the contract’s conditions without satisfying the real world conditions intended for a valid spend, you are solid - oh, and one more thing: you need to make sure that a satisfier script CAN be constructed, so that those coins aren’t gone for good 😅

[David T @DPTib]

@Luisenriquepl @lenntreve You certainly could, but as always, extra caution needs to be taken. The NPL skill will give your agent a solid understanding of how to write contracts using Nexa’s Kotlin DSL. The more complex the contract you aim for, the more you need to test the hell out of it. pt1…

[David T @DPTib]

@Luisenriquepl @lenntreve Pt2… use testnet so in case you lock coins forever, it won’t cost you anything. Be thoughtful about attacks and ways for adversaries to create transactions which can trick your contract’s spend rules into releasing funds. As long as you are sure that a script can’t be created…

[David T @DPTib]

@lenntreve @TheDonAlucard @ZYDEXN @NexaMoney Don’t tempt @TheDonAlucard with those 😂

[David T @DPTib]

For anyone wanting a tough challenge or any doubters of @PeterRizun ‘s hardware wizardry, there’s still bitcoin:native waiting to be collected…

For the rest of us, we’ll be looking forward to seeing this get put to use for the next generation of nexacoin:native ‘s mining

📒 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.

Read more and find all the details on the Nexa Forum below. 👇

[David T @DPTib]

@Traderfgr Yeah, I’d love to check your game out! I will check the channel

[David T @DPTib]

Time for updates!

The start of Q4 is no time to sleep on nexacoin:native - blink, and you might miss one of the many updates, dev checkpoints, or major tech improvements that are about take off. 🚀🚀

@NexaMoney team is building every day, and this is the home stretch of 2026!

📒 Nexa Monthly Newsletter September 2026: Ahead of the Storm

September was a very active month, with many significant developments across the ecosystem. It started with the release of Nexa Full-Node 2.2.0.0, a major core protocol release that included preparatory work for Tailstorm.

Equally significant was the release of AI skills with the Starter App, which provides pre-wired Nexa infrastructure with wallet integration, ready for building decentralized applications on top of it. Huge appreciation goes to David Thibodeau (@DPTib) for all the hard work and the presentation.

Along with the AI skills, the team also released an updated Build On Nexa (BON) program website that includes AI-assisted development, all the libraries, and other developer tools essential for blockchain development.

We have also been recapping and reintroducing the work being done on hardware acceleration and Blitz. This work involves heavy development and wiring the silicon for digital signature verification. Most of the hard work is already done and tested, and we are moving into the next phases.

Find these and many more developments in the September 2026 monthly newsletter below. 👇

[David T @DPTib]

@ultrasoundape @NexaMoney Doing all this, just to arrive back on the original path they started from… and then realizing that projects like nexacoin:native are much further along, because @NexaMoney never strayed from that original path to begin with

[David T @DPTib]

@NexaMoney ‘s own hardware expert and chief scientist has got a challenge open to anyone:

He’s confident that his FPGAs can outperform the best GPUs on a dollar-cost basis by 100x - and he’s got BTC bounties to back it up!

Miners should have their eyes on nexacoin:native 👀🚀

[Peter R. Rizun @PeterRizun]

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.

@Thebitcoinbarb1 Can’t be sleeping on the DMX

[David T @DPTib]

@RonSwanonson I agree with one caveat: BTC could be improved upon, but it won’t - because of those who maintain the code. BCH also chose to impose their own limitations.
Finally, nexacoin:native came from that same code. Everything you could want in an L1. Still PoW. What BTC should have been

[David T @DPTib]

Comment your best #deFi app ideas below… but then don’t just move on and forget about it - @NexaMoney gives you the tools you need to actually build it!!

nexacoin:native is one of the easiest blockchains to build on - no need to be an experienced dev

Let’s see what you got 💪

[Nexa @NexaMoney]

A quick demonstration of how to build an app with a Claude agent and AI-assisted development. On top of Nexa AI skills and the Starter App, it takes only a single prompt to get a fully functioning application.

@ultrasoundape For real, when people go crazy with unfounded hate in the comments, it’s usually because they have no real logic to refute or counter with…

we’ll spend our time building more on nexacoin:native while they spend more time mad about other projects 💪😎🚀

[David T @DPTib]

It’s funny how the government can remain so far behind the available technology…

Who would have ever thought that KYC data collection was just creating giant honeypots for hackers?

Oh wait - I wonder why everyone in crypto has wanted to avoid KYC from the beginning 🤔

[Coin Bureau @coinbureau]

🚨JUST IN: SEC Commisioner calls to END mass KYC data collection.

Hester Peirce warns existing KYC/AML frameworks create huge databases of sensitive user data, making them prime targets for hacks, phishing and even physical attacks.

She is pushing zero-knowledge proofs as an alternative, allowing users to prove compliance without exposing their personal data.

@WhaleScan nexacoin:native for the win!
