A Storefront Instead of a Safe: What Public Blockchains Do With Your Financial Life
Imagine a bank that puts every customer's statement in the shop window. Every transfer. Every balance. Years of history, free to read for anyone walking past. There are no names on the signs, only account numbers. But the moment one number is tied to a real person, that person's entire financial life becomes public.
For anyone hunting for a target, no better instrument could be designed. Why spend effort breaking into a wallet that may hold nothing? Read the window first. Pick the full ones.
This is not a thought experiment. It is a description of Bitcoin and Ethereum, the two networks most often called the future of money.
Why it happened
Public visibility was not ideology. It was engineering.
The problem in 2009: thousands of strangers must agree on balances without a bank in the middle. The answer was elegant. Let everyone verify everyone. And to verify everything, everyone has to see everything.
It worked. The price was written in the fine print: every participant's financial history stays public forever.
Banking spent three centuries building the opposite rule. Bank secrecy is not a luxury for the wealthy. It is hygiene. Your employer should not see where your salary goes. Your competitor should not see your turnover. A stranger should not know your savings, if only because that knowledge attracts worse people than advertisers.
The industry proposed to build the future of finance by discarding that on day one.
The analytics industry that grew inside the window
What followed was predictable. Data that is public gets collected, linked and sold.
An entire sector now exists to tie wallet addresses to real identities and sell those links to exchanges, institutions and governments. The pseudonymity of a public ledger turned out to be weaker than ordinary bank privacy. A bank needs a court order to hand over your account. A public ledger needs nothing at all.
What the window costs: three receipts
People. Security researcher Jameson Lopp has maintained a database of physical attacks on cryptocurrency holders since 2014. It records 41 documented attacks in 2024 and more than 70 in 2025, and those figures almost certainly undercount, because victims of violent crime have strong reasons to stay quiet. More than 200 attacks have been registered in total. Attackers no longer guess who holds value. They read it off a block explorer.
Addresses. Address poisoning works only because your history is public and copyable: an attacker generates a wallet whose first and last characters match one you already paid, sends you a dust transaction, and waits for you to copy the wrong line out of your own history. Scanning the entire Bitcoin chain, Lopp identified roughly 48,000 suspected attacks of this kind since 2023. On Ethereum, one user sent $71 million to a lookalike address, later recovered.
Orders. On Ethereum, pending transactions wait in a public mempool where anyone can read them before they settle. Cumulative MEV extracted on Ethereum has passed $1.2 billion, with sandwich attacks accounting for roughly half of it. Trader losses to sandwiching ran at about $60 million a year at the peak, and monthly extraction fell from roughly $10 million in late 2024 to about $2.5 million in October 2025, as traders moved their orders into private routes.
Read that last clause again. The industry's own remedy for the problem was privacy.
The quantum clock
Quantum risk is usually filed under science fiction. The mechanism is not fiction. It is arithmetic.
Elliptic-curve signatures are vulnerable to Shor's algorithm. To derive a private key, an attacker does not need to break the network. He needs an address and its public key. In Bitcoin, legacy p2pk addresses expose the key by default; modern addresses expose it the moment funds are spent.
Deloitte's analysis of the full Bitcoin ledger (Barmes, Bosch and Haalstra) put the exposed set at over 4 million BTC, about a quarter of all bitcoin in existence at the time of the study.
Transparency does not merely publish your money today. It pre-loads the input data for tomorrow's attack.
The attempts at privacy, and the backlash
Monero built hidden amounts and obfuscated counterparties into the protocol itself. The answer came from the market side: major exchanges delisted it, and privacy assets were pushed out of regulated venues across jurisdictions. The network runs. It runs in exile, penalised not for a proven crime, but for the property of privacy itself.
Tornado Cash is the sharper case. OFAC designated the mixer in August 2022; it had never before targeted a decentralised protocol, and what was on the list was published code. On 26 November 2024 the Fifth Circuit held that OFAC had exceeded its authority, finding that immutable smart contracts are not property under IEEPA. On 21 March 2025 the Treasury removed the sanctions. The criminal prosecution of the developers continued regardless, and one founder stayed designated under North Korea sanctions.
The signal to anyone building was legible: privacy is treated as a threat first, and examined by a court afterwards.
Why the state wants the window open
No conspiracy is required here, only a list of state functions. Collect taxes. Enforce sanctions. Freeze assets on a court order. Seize criminal proceeds.
All four need two things: visibility of assets, and the ability to stop a transfer.
A fully transparent ledger with a freeze switch is a better surveillance instrument than a bank, because a bank at least demands paperwork. A shop window asks the viewer for nothing. That is the whole problem: the same properties that serve a lawful investigation also serve everybody else, with no boundary and no record.
What honest people need secrecy for
- Receiving a salary without handing your lifetime financial history to every counterparty.
- Running a business without showing competitors your turnover and your supplier costs.
- Holding savings without lighting a beacon for extortionists.
- Paying a clinic, a lawyer or a charity without leaving a permanent, searchable public trail.
This is not a demand from criminals. It is the baseline the financial system has kept for three centuries.
How we built it at AYA Network
We did not invent a compromise. We restored the banking rule: closed by default, open to legitimate authority.
Closed by default. Knowing an address gets you nothing. A request for someone else's balance is refused by the node. No passer-by, no analytics firm, no employer can read a user's balances, holdings or transfer amounts.
We do have an explorer. It simply cannot show you other people's money. AYA CORE Explorer verifies exactly what an owner has chosen to disclose, and nothing else. Network-level totals are a different matter and are published openly: symbols issued, addresses holding a balance, treasury, with a link to the raw data. Aggregates in the window, individuals in the safe.
The owner's one-hour window. The wallet holder generates a view key himself. It is valid for exactly one hour. It is read-only: balances, incoming and outgoing transfers. It cannot spend and it cannot freeze. Hand it to a bank, an auditor, a lawyer, an investigator, and it expires on its own, so it cannot circulate the internet indefinitely or feed passive harvesting.
The legal channel, stated plainly. We will not claim that nobody can ever see anything; that would be untrue, and untrue claims are how trust dies. Nodes keep state by address. That is the engineering reality of any ledger. So here is the honest version: on an official, legally valid request, the state of one specific address can be disclosed. One address. Not the history of every other user. That is a documented responsibility of the operator, not an open door for anyone who knows your address.
And here is the limit that matters more than any of it: disclosure is read-only. No key in this system, ours included, can move or freeze another person's funds. Value moves on the owner's signature or it does not move. We have written before about where total control over a wallet leads.
We chose this model deliberately, over absolute opacity. Networks that made privacy total now live outside the regulated world. A network meant to carry salaries and business payments has to be able to answer a court, and to answer it without undressing everyone else in the process.
On the quantum question. Our signatures are ML-DSA-87 (FIPS 204), a NIST-standardised post-quantum scheme; Shor's algorithm does not apply to it. Privacy is the second lock, not the only one. Even where the mathematics holds, we see no reason to publish every user's address, key and balance for the convenience of the curious.
The SWIFT comparison
Consider how international banking actually works. Banks do not publish MT103 or ISO 20022 payloads, routing keys or confirmation hashes to the open internet. Not because they are concealing crime, but because no outsider has an operational need for them, and publishing them would be an invitation to fraud. That plumbing stays inside SWIFTNet.
AYA Network applies the same principle: cryptographic internals stay inside the protocol, transaction details reach authorised parties only, and access is bounded in time.
In place of a conclusion
A public shop window with everyone's money is not the future.
A safe with a documented, lawful access procedure is.
AYA CORE is a post-quantum Layer-1 blockchain built from scratch in Rust. Read the documentation at portal.ayacoin.online/docs, verify a disclosed balance through the public AYA CORE Explorer, and hold the keys yourself: the wallet runs at ayacoin.online and is available on the App Store and Google Play.
