Claude didn't crack a Bitcoin wallet.

It debugged the recovery. Old file, btcrecover, wrong input, fixed, keys verified.
AI connecting technical dots in action.

Timely note:
if you have old wallets - check your recovery setup now.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Bitcoin security is built for the long term.

But the quantum threshold is moving faster than many expected.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

@AIgorStadnyk another proof AI is not just something cool, but it really changes things.
(if people take it seriously)

[Julia Stadnyk @julia_b_6]

There are 3 types of engineers in the AI era:

1. 'AI is hype. I don’t use it'
2. 'AI does everything now'
3. 'Hmm… let me test this'

The third group is the most interesting:

- yesterday skeptical
- today they’ve tried five tools and say: Ok, this one actually works. Let’s use it

That’s how real adoption happens.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

@AIgorStadnyk interesting

[Igor Stadnyk (🇺🇸,🇵🇹,🇺🇦) @AIgorStadnyk]

ppl sleeping on this:

AI agents now exploit smart contracts with 72% success
6 months ago it was 31%.

$100B+ secured by code.

capability scaling:
ai evolving from a copilot into core defi infrastructure

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

@AIgorStadnyk really interesting direction

seems AI-driven auditing could soon become standard for smart contracts

curious how fast the ecosystem adopts it.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Cross-chain data is messy rn

AI agents will make this problem even bigger.
AI needs clean, structured, standardized data.

The solution is simple in theory:
shared data standards and mature infrastructure.

Without this, autonomous finance won’t scale.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Easy to think new consensus models solve old problems.

In reality, most bottlenecks just move around.
Infrastructure is still where things get hard...

#Ethereum killed mining.
It didn’t kill latency.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Btw, same pattern we saw with AI.

First it stresses the system. Then it makes it stronger.

Quantum won’t kill crypto.
But it will show who's prepared and who waited too long.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

You have ~5 years.

Heard this from my friend, founder building quantum systems.

Quantum computing is moving fast.

Not 'breaking crypto tomorrow' fast, but fast enough not to ignore it.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

For crypto, this doesn’t mean panic.

It means doing a few very basic things now:

• build crypto-agile protocols
• plan hybrid → post-quantum migrations
• assume upgrades take years, not weeks

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Security is the bottleneck of Web3 now.

From what I see, scams scale faster than protocols.
AI scales everything - attacks included.

Transparency helps.
Architecture and threat modeling matter more.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Web3 shouldn’t be visible to users.

It should be reliable, scalable, and boring -
while gradually creating new business models.

[INC4 @INC_4_]

1/ Real #Web3 #case to start 2026 👇

We built a production backend for music NFTs.
Not a demo. Not a PoC.

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

100%

[Igor Stadnyk (🇺🇸,🇵🇹,🇺🇦) @AIgorStadnyk]

bet you know this story:

- ppl say chatGPT sounds like a Kenyan moderator

respect, they did huge work.

but imagine ChatGPT after learning from 10,000 Ukrainians:

• less 'i’m sorry, but…'
• more 'here’s the solution, let’s go'
• straight to the point
• practical as hell

📌 more sense. less emotion.

Ukraine has one of the largest english-speaking tech communities in Europe.

AI would finally stop overthinking and start shipping.

what do u think here?

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

Social platforms today feel more like high-load systems than media apps.

Interesting how architecture choices define scalability from day 1👇

#Social_platforms are booming rn

New formats, new monetization models, new ways for creators to take control.

We’re happy to be not just watching this wave but building products that ride it.

One of them: #Yofan, a platform for creator monetization.
https://t.co/5aeriv0HX5

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

One of the most interesting directions rn:
#AIAgents testing real security boundaries of smart contracts.

$4.6M in simulated exploits isn’t the scary part - scary part is how systematic these attack paths already are.

Blockchain & AI were always destined to intersect here

[Anthropic @AnthropicAI]

New on our Frontier Red Team blog: We tested whether AIs can exploit blockchain smart contracts.

In simulated testing, AI agents found $4.6M in exploits.

The research (with @MATSprogram and the Anthropic Fellows program) also developed a new benchmark: https://t.co/QpGPMqlDRG

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

The shift we’re seeing is architectural.

New cryptography gives us new design space.

That’s real story.

[mert @mert]

you've likely heard at some point that blockchains are transparent and this is good and as designed

this is false

they are transparent because we didn't know how to prevent double spends without revealing everyone's balances

we know how to do it now, via zk

don't be late

[Valerii Marshalin (🇺🇦,🇺🇦) @V_Marshalin]

#Dubai remains one of the strongest crypto hubs out there.

Binance Blockchain Week always cuts through the noise - real builders, real infra talks.

Our team will be around.

[INC4 @INC_4_]

#Dubai is calling.
@binance BlockchainWeek is calling.

We’re answering.
Are you?

Let’s meet in Dubai soon🤝

ZK is what makes blockchain (and soon AI) provable, not just trust-based.

[a16z crypto @a16zcrypto]

ZK proofs have become critical to blockchain privacy and scaling.
