Web3 rolled in on the wave of decentralization. Decentralized applications (DApps) grew by 74% in 2024 and individual wallets by 485%, with total value locked (TVL) in decentralized finance (DeFi) closing at a near-record high of $214 billion. The industry is also, however, heading straight for a state of capture if it does not wake up.
As Elon Musk has teased of placing the US Treasury on blockchain, however poorly thought out, the tides are turning as crypto is deregulated. But when they do, is Web3 ready to “protect [user] data,” as Musk surrogates pledge? If not, we’re all on the brink of a global data security crisis.
The crisis boils down to a vulnerability at the heart of the digital world: the metadata surveillance of all existing networks, even the decentralized ones of Web3. AI technologies are now at the foundation of surveillance systems and serve as accelerants. Anonymity networks offer a way out of this state of capture. But this must begin with metadata protections across the board.
Metadata is the new frontier of surveillance
Metadata is the overlooked raw material of AI surveillance. Compared to payload data, metadata is lightweight and thus easy to process en masse. Here, AI systems excel best. Aggregated metadata can reveal much more than encrypted contents: patterns of behaviors, networks of contacts, personal desires and, ultimately, predictability. And legally, it is unprotected in the way end-to-end (E2E) encryptedcommunications are now in some regions.
While metadata is a part of all digital assets, the metadata that leaks from E2E encrypted traffic exposes us and what we do: IPs, timing signatures, packet sizes, encryption formats and even wallet specifications. All of this is fully legible to adversaries surveilling a network. Blockchain transactions are no exception.
From piles of digital junk can emerge a goldmine of detailed records of everything we do. Metadata is our digital unconscious, and it is up for grabs for whatever machines can harvest it for profit.
The limits of blockchain
Protecting the metadata of transactions was an afterthought of blockchain technology. Crypto does not offer anonymity despite the reactionary association of the industry with illicit trade. It offers pseudonymity, the ability to hold tokens in a wallet with a chosen name.
Harry Halpin and Ania Piotrowska have diagnosed the situation:
“[T]he public nature of Bitcoin’s ledger of transactions […] means anyone can observe the flow of coins. [P]seudonymous addresses do not provide any meaningful level of anonymity, since anyone can harvest the counterparty addresses of any given transaction and reconstruct the chain of transactions.”
As all chain transactions are public, anyone running a full node can have a panoptic view of chain activity. Further, metadata like IP addresses attached to pseudonymous wallets can be used to identify people’s locations and identities if tracking technologies are sophisticated enough.
This is the core problem of metadata surveillance in blockchain economics: Surveillance systems can effectively de-anonymize our financial traffic by any capable party.
Knowledge is also an insecurity
Knowledge is not just power, as the adage goes. It’s also the basis on which we are exploited and disempowered. There are at least three general metadata risks across Web3.
Fraud: Financial insecurity and surveillance are intrinsically linked. The most serious hacks, thefts or scams depend on accumulated knowledge about a target: their assets, transaction histories and who they are. DappRadar estimates a $1.3-billion loss due to “hacks and exploits” like phishing attacks in 2024 alone.
Leaks: The wallets that permit access to decentralized tokenomics rely on leaky centralized infrastructures. Studies of DApps and wallets have shown the prevalence of IP leaks: “The existing wallet infrastructure is not in favor of users’ privacy. Websites abuse wallets to fingerprint users online, and DApps and wallets leak the user’s wallet address to third parties.” Pseudonymity is pointless if people’s identities and patterns of transactions can be easily revealed through metadata.
Chain consensus: Chain consensus is a potential point of attack. One example is a recent initiative by Celestia to add an anonymity layer to obscure the metadata of validators against particular attacks seeking to disrupt chain consensus in Celestia’s Data Availability Sampling (DAS) process.
Securing Web3 through anonymity
As Web3 continues to grow, so does the amount of metadata about people’s activities being offered up to newly empowered surveillance systems.
Beyond VPNs
Virtual private network (VPN) technology is decades old at this point. The lack of advancement is shocking, with most VPNs remaining in the same centralized and proprietary infrastructures. Networks like Tor and Dandelion stepped in as decentralized solutions. Yet they are still vulnerable to surveillance by global adversaries capable of “timing analysis” via the control of entry and exit nodes. Even more advanced tools are needed.
Noise networks
All surveillance looks for patterns in a network full of noise. By further obscuring patterns of communication and de-linking metadata like IPs from metadata generated by traffic, the possible attack vectors can be significantly reduced, and metadata patterns can be scrambled into nonsense.
Anonymizing networks have emerged to anonymize sensitive traffic like communications or crypto transactions via noise: cover traffic, timing obfuscations and data mixing. In the same spirit, other VPNs like Mullvad have introduced programs like DAITA (Defense Against AI-guided Traffic Analysis), which seeks to add “distortion” to its VPN network.
Scrambling the codes
Whether it’s defending people against the assassinations in tomorrow’s drone wars or securing their onchain transactions, new anonymity networks are needed to scramble the codes of what makes all of us targetable: the metadata our online lives leave in their wake.
The state of capture is already here. Machine learning is feeding off our data. Instead of leaving people’s data there unprotected, Web3 and anonymity systems can make sure that what ends up in the teeth of AI is effectively garbage.

Blockchain infrastructure provider Figment has been selected as the staking provider for 3iQ’s newly approved Solana exchange-traded fund (ETF), underscoring Canada’s continued efforts toward adoption of digital asset financial products.
Figment will enable institutional staking for the 3iQ Solana (SOL) Staking ETF, which launches on the Toronto Stock Exchange on April 16 under the ticker SOLQ, the companies said in a statement. In addition to 3iQ, Figment provides staking infrastructure solutions to more than 700 clients.
The Ontario Securities Commission (OSC), a provincial regulator, green-lighted 3iQ’s SOL fund on April 14. The approval was also extended to other fund managers seeking to offer SOL ETFs, including Purpose, Evolve and CI.
It would take nearly three more years before spot Bitcoin ETFs were approved in the United States. Like their Canadian counterparts, the US ETFs saw overwhelming success in their first year, generating more than $38 billion in net inflows.
In October 2023, 3iQ launched an ETF tied to Ether (ETH), giving investors direct access to the smart contract platform. Unlike the Ether ETFs that US regulators approved the following year, 3iQ’s fund offers staking rewards.
As Cointelegraph recently reported, US regulators may be on the cusp of approving staking rewards after they authorized exchanges to list options contracts tied to ETH.
Synthetic stablecoin developer Ethena Labs is winding down its German operations less than a month after regulators identified “deficiencies” in its dollar-pegged USDe (USDE) stablecoin, signaling heightened scrutiny around crypto assets in Europe’s largest economy.
Ethena Labs reached an agreement with Germany’s Federal Financial Supervisory Authority, also known as BaFin, to cease all operations of its local subsidiary, Ethena GmbH, according to an April 15 announcement.
As such, Ethena Labs “will no longer be pursuing MiCAR authorization in Germany,” the company said, referring to the Markets in Crypto-Assets Regulation.
The company reiterated that Ethena’s German subsidiary has not conducted any mint or redeem activity for USDe since March 21, the day BaFin halted the stablecoin’s activities. As Cointelegraph reported at the time, the German regulator identified compliance failures and potential securities law violations tied to USDe.
“All whitelisted mint and redeem users previously interacting with Ethena GmbH have at their request been onboarded with Ethena (BVI) Limited instead and have no ongoing relationship with Ethena GmbH whatsoever,” the company said.
Unlike popular stablecoins USDt (USDT) and USDC (USDC), Ethena’s USDe maintains its dollar peg through an automated delta-hedging strategy that includes a combination of spot holdings, onchain custody and liquidity buffers.
USDe is the fourth-largest stablecoin with a total circulating value of $4.9 billion, according to CoinMarketCap.

To meet the new requirements, stablecoin issuers must have adequate reserves backing their tokens, ensure reserve assets are segregated from users’ assets and fulfill regular reporting obligations.
Patrick Hansen, Circle’s senior director of EU strategy and policy, told Cointelegraph that a total of 10 euro-pegged stablecoins and five US dollar-pegged stablecoins have been approved so far.
However, notably absent from the list is USDt issuer Tether, which has decided not to pursue MiCA registration at this time.
The crypto industry’s inability to access banking services still concerns many industry observers despite recent policy victories.
In past years, financial services firms and banks concerned about fiduciary risk, reporting liabilities and reputational risk often would refuse to offer service to crypto firms — i.e., “debanking” them.
Legislative efforts in the United States and Australia are attempting to remove these barriers for the crypto industry. In the former, legislators repealed guidelines that made it difficult for banks to custody crypto assets, as well as those stating that crypto carried “reputational risk” for banks. In the latter, the Labor Party has introduced a bill to create a legal framework for crypto, giving banks the clarity they need to interact with the crypto industry.
Despite these tangible efforts, some crypto industry observers say that the crypto’s debanking problem is far from over.
US crypto execs say debanking is still an issue
The crypto industry has long decried “Operation Chokepoint 2.0,” its nickname for a suite of policies that they claim constrained the crypto industry from growing under the administration of former President Joe Biden. Among these were measures making it more difficult for crypto firms to access banking services.
The early days of the second administration of President Donald Trump have seen many of these repealed or changed. One of the first was the repeal of Staff Accounting Bulletin 121, which required banks offering custody for customers’ cryptocurrencies to list them as liabilities on their balance sheets — this made it very difficult for banks to justify offering such services.
The administration also appointed a new head of the Office of the Comptroller of the Currency (OCC), Rodney Hood. Dennis Porter, CEO of the Bitcoin-focused policy organization Satoshi Action, told Cointelegraph that under Hood’s tenure, the OCC has already said banks can offer crypto-related services like custody, stablecoin reserves and blockchain participation.
“This opens the door for broader adoption of digital asset technology and custodial services by traditional financial institutions, signaling a major shift in how banks engage with crypto,” he said.
Despite these victories, Caitlin Long, founder and CEO of Custodia Bank, said on March 21 that debanking is likely to remain a problem for crypto firms into 2026.
Long said the non-partisan board of governors of the Federal Reserve is “still controlled by Democrats,” alluding to Democrats’ more skeptical stance on crypto. Long claimed that “there are two crypto-friendly banks under examination by the Fed right now, and an army of examiners was sent into these banks, including the examiners from Washington, a literal army just smothering the banks.”
Long noted that Trump won’t be able to appoint a new Fed governor until January, meaning that, while other agencies may be more crypto-friendly, there are still roadblocks.
Australia’s Labor Party to create crypto framework
Stand With Crypto, the “grassroots” crypto advocacy organization started by Coinbase that has spread to the US, UK, Canada and Australia, said that “in Australia, debanking is quietly shutting out innovators and entrepreneurs — particularly in the crypto and blockchain space.”
In a post on X, the organization claimed that debanking results in “reputational damage, loss of revenue, increased operational costs, and inability to launch or sustain services.” It also claimed that it forces some companies to move offshore.
In response to these concerns, the ruling center-left Labor Party in Australia has proposed a new set of laws for the cryptocurrency industry. The changes to current financial services law seek to tackle the issue of debanking in the country’s cryptocurrency industry.
Edward Carroll, head of global markets and corporate finance at MHC Digital Group — an Australian crypto platform — told Cointelegraph that in Australia, debanking decisions were “not the result of regulatory directives.”
“Rather, they appear to stem from a more general sense of risk aversion due to the current lack of a clear regulatory framework.”
Carroll was optimistic about the Labor Party’s proactive stance. The major political parties were “showing a shift in sentiment and a shared commitment to establishing formal crypto regulation.”
“We are hopeful that this will give banks the confidence to reengage with crypto businesses that meet compliance standards,” he said.
Canada unlikely to relieve crypto firms
In Canada, “debanking remains a serious and ongoing challenge for the Canadian crypto industry,” according to Morva Rohani, executive director of the Canadian Web3 Council.
“While some firms have successfully established relationships with banking partners, many continue to face account closures or denials with little explanation or recourse,” she told Cointelegraph.
While debanking actions aren’t explicit, financial institutions’ interpretation of Anti-Money Laundering and Know Your Customer regulations “creates a risk-averse environment where banks weigh compliance and reputational concerns against the relatively low revenue potential of crypto clients.”
The end result, per Rohani, is a systemic debanking problem for the digital assets industry.
But unlike in the US and Australia, the Canadian crypto industry may not find relief anytime soon. Prime Minister Mark Carney, whose more crypto-skeptic Liberal Party is surging in the polls ahead of the April 28 snap elections, is himself a crypto-skeptic.

Carney has stated that the future of money lies more in a “central bank stablecoin,” otherwise referred to as a central bank digital currency.
Rohani said that “no comprehensive legislative solution has been implemented” with regard to debanking. “A more structured approach, including mandated disclosure of reasons for account termination and regulatory oversight, is needed,” she said.
Critics claim crypto is “hijacking” the debanking issue
There is another side to the debanking debate, which claims that crypto’s debanking “problem” is a non-issue or a vehicle for crypto firms to get what they want in terms of regulation.
Molly White, the author of Web3 Is Going Just Great and the “Citation Needed” newsletter, has noted that, in the US at least, crypto firms have claimed to be victims of debanking while lauding Trump’s efforts to end protections for debanking at the same time.
In a Feb. 14 post, White stated that the crypto industry had “hijacked” the discussion around debanking, which contains legitimate concerns regarding access to financial services — particularly regarding discrimination due to race, religious identity or industry affiliation.
She claims the crypto industry has used debanking as a means to deflect legitimate regulatory inquiries into crypto companies’ compliance efforts.
Further of note is the fact that Coinbase CEO Brian Armstrong has applauded the efforts of the Department of Government Efficiency (DOGE), with Elon Musk at the helm, to dismantle the Consumer Financial Protection Bureau (CFPB).
One of the CFPB’s responsibilities is to investigate claims of debanking. But when DOGE instructed the agency to halt all work, Armstrong said it was “100% the right call,” in addition to making dubious claims about the agency’s constitutionality.
In the meantime
Whether the industry’s debanking concerns stem from legitimate discrimination or an attempt at regulatory capture, crypto firms are developing solutions in the interim.
Porter said that, as an alternative to banking services, “many crypto companies have leaned on stablecoins as a primary tool for managing finances,” while others have worked with “smaller regional banks or specialized trust companies open to digital assets.”
Rohani said that this kind of “patchwork of relationships” can increase operational costs and risks and are “not sustainable long-term solutions for growth or to build a competitive, regulated industry.”
Porter concluded that the banking workarounds could actually strengthen the industry’s position, stating that they may “continue evolving into fully integrated relationships with traditional financial institutions, further cementing crypto’s place in mainstream finance.”
