Grok can do more than answer questions.
I asked it to build a live Fourier transform visualizer. It delivered this:
Type any formula and the time-domain signal and spectrum update instantly.
Try it: blaze-plaza-drum-wave.grok.m…
What else should we build?

No soft forks, no bridges, no operators, just Bitcoin.
We’ve put a lot of work into thinking carefully about the security of Shielded Bitcoin and about what information the protocol reveals. And this is just the beginning!

Developers just figured out a way to hide who sent bitcoin, who received it, and how much moved, without changing Bitcoin itself.
This new proposed idea is not a fork around the protocol or new cryptocurrency. This is how Bitcoin was designed, a base layer people can innovate on without asking permission.
On Thursday, researcher Misha Komarov and colleagues published Shielded Bitcoin, a Zcash-style shielded pool for Bitcoin’s base layer.
Encrypted notes and zero-knowledge proofs ride along in ordinary Bitcoin transactions. Separate software checks that no coins are created from nothing and none are spent twice.
There is no company running the pool, no sidechain, and no soft fork. Funds go in and out through cryptographic vaults Komarov has been building, called PIPEs, so no federation has to hold the bitcoin.
Miners do not enforce the privacy rules. Invalid shielded data can still land in a block, indexers simply ignore it.
The trade is: Bitcoin stays conservative, and the experiment lives on top of it. If it works, private transfers arrive the way most of Bitcoin’s best ideas have, not by rewriting the constitution, but by building on the settlement layer everyone already trusts.

Masterclass happening right now. Never let a good crisis go to waste. For my US friends I would be happy recommending @avici - because you learn more about a company with how they handle when something bad happens than during “normal operations” - they deserve flowers here.
UPDATE: Refunds are processed in full, with an extra 10% cashback.
The Solana contract has been updated. We haven't seen any further related activity, and we're constantly monitoring it.
If your Solana card balance was withdrawn a few hours ago, we've restored the full amount and added 10% cashback on what was withdrawn. Open the app and cross-check your balance.
Here's exactly what was affected and what wasn't:
1. This was limited to card contracts on Solana holding balances added through Avici's Top Up flow.
2. Your regular Avici Solana and EVM wallets were never affected. Those wallets are self-custodial and stayed under your control the entire time.
3. EVM card balances, onramps, offramps, and swaps were not affected.
4. Funds outside these Solana card-balance contracts were never exposed.
We made a very deliberate choice to keep your Avici wallet separate from your card balance. It's why you have to manually Top Up before spending. Combining both would've made the app easier to use, but we didn't do it because we believed keeping them separate was safer.
That separation is why this stayed limited to the affected Solana card contracts while wallets and everything else in Avici stayed untouched. That doesn't make what affected users went through okay. We're sorry for the stress and uncertainty this caused.
We're not proud that this happened. We are proud that Avici is built onchain, where balance movements are immediately visible and independently verifiable instead of hidden behind a private ledger. In traditional fintech, the number shown in an app can stay unchanged while what is happening underneath remains invisible. Here, anyone could see the movement onchain as it happened.
We're pushing the frontier of onchain finance, and that road was never going to be easy. Moments like this are painful and humbling, but they show us what has to improve and will make Avici stronger. We're not stepping back. We're going to keep pushing forward.
Rain, our card issuing partner, covered all reimbursements in full. Huge credit to their team for moving quickly, working closely with us, restoring every affected balance, and fixing the issue.
We'll publish a full postmortem once the investigation is complete.
And a huge thank you to every partner who jumped in immediately to help us through this: @solana, @raincards, @Helius, @MetaDAOProject, @zeroshadow_io, and @asymmetric_re.
Thank you for staying with us through the uncertainty and stress this caused today.

UPDATE: All affected card balances will be refunded in full
Earlier today, our card-issuing partner, Rain, identified a vulnerability in an version of a Solana card contract used by Avici and a small number of other programs. The contract has now been upgraded across all programs, and no further unauthorised activity has been observed.
Avici wallets and card balances are separate. Avici wallets are self-custodial and remain under users’ control.
When users top up their cards, funds move into a separate Solana contract that holds their card balance. Only this contract was affected.
Note: Funds held in Avici’s Solana and EVM wallets are safe and were not affected.
Our current reconciliation shows that 1,685 users were affected, representing $500,859.22 in card balances.
Every affected user will have their card balance refunded in full. We remain in close contact with our card-issuing and security partners and are monitoring the remediation closely.
Avici has also filed a report with the FBI’s Internet Crime Complaint Center. We are deeply sorry for the concern and inconvenience this has caused.

Atlas Shrugged made simple:
1. Society runs on a small number of highly capable producers – industrialists, inventors, engineers – whose work everyone depends on but takes for granted.
2. The system starts rewarding need over achievement: the more capable you are, the more you’re expected to sacrifice for those who aren’t.
3. Success gets treated like a debt – taxed, regulated, resented – until the most capable start asking why they bother trying at all.
4. One by one, led by a man named John Galt, they simply withdraw – walking away rather than keep propping up a system that punishes them for producing.
5. Without them, the whole structure collapses, revealing that the “automatic” prosperity everyone assumed was actually being generated by specific, irreplaceable people.
6. Atlas is the Titan from Greek myth, condemned to carry the sky on his shoulders forever – Rand’s stand-in for the producer class, holding up civilization while getting blamed for it.
7. “Shrugged” is the whole argument in one word: Atlas doesn’t fight, doesn’t protest – he just quietly sets the weight down. Nobody realized the sky was being held up by anyone in particular, until the day it isn’t.
You don’t want us? We just go…🤷🏻♂️
The Road to Serfdom made simple:
1. Plan the whole economy: someone must decide what gets made and who gets what, since people don’t naturally agree on one set of priorities.
2. These decisions are too big and detailed for normal democratic debate, so power shifts to a smaller group who can just act – technocrats.
3. Fixed laws everyone can rely on get replaced by case-by-case rulings, because a plan needs flexibility, not predictability.
4. Dissent becomes a problem to manage, not an opinion to vote on – the plan can’t work if people are free to ignore it.
5. Enforcing all that selects for people most willing to be ruthless – Hayek’s “worst get on top” – i.e. negative moral selection.
6. Since economics touches everything (your job, home, speech), controlling the economy ends up controlling your whole life.
That’s the "serfdom."
As a third-world resident, I've been shut out of global finance—high fees, endless paperwork, no credit access. But $AVICI changes everything!
