Rewards were supposed to be given to those who actually made use of a protocol, airdrops.

However, there's always been an issue lurking behind that idea.

A single user can generate hundreds or thousands of wallets, use them all in a protocol, and get rewarded from it as if they were different users.

This is the Sybil problem.

And it's becoming harder to resolve.

The industry is moving towards this; Base has recently published an article on Verify Onchain, which demonstrates how the protocols can decide whether several wallets are owned by the same person based on external identity signals, rather than just on the wallet. It is not an indication of the Base network token or an airdrop of any kind, it is being tested.

On the surface, this might seem like a simple upgrade.

However, the larger question is,

What degree of identity does a crypto user need to sacrifice to demonstrate that he or she is a real person?

The Wallet Was Never a Perfect Identity

It was one of the original assumptions behind crypto that:

A wallet address is not a person, it's an account.

That's something nice to have.

They can have one wallet for their DeFi, one for their NFTs, one for all the new apps that they want to try and one for just holding their assets.

However, in the eyes of the blockchain, all such addresses may be viewed as independent users.

This poses a challenge for airdrop developers.

A Sybil operator can generate many addresses and make them look active if a project implements a wallet activity based distribution.

These studies are now recent investigations that reveal that this is not just a theoretical dilemma. Bitquery's September 2026 Fabric Protocol ROBO distribution report revealed that 11,204 wallets were in the hands of one group, which accounted for 87% of the tokens distributed.

That's why projects are looking for anything more than wallet counting.

The New Approach: Prove That You Are One User!

Base Verify isn't like that.

Rather than asking just:

What activities has this wallet been involved with?"

the system may also inquire:

“Is there a verified digital identity that can be linked to this wallet?”

The technology can leverage verification from off-chain entities like X, Coinbase, Instagram and TikTok, but try and do not put the underlying personal information directly on-chain. As per the BaseHub docs, the Base Verify infrastructure is currently designed to facilitate both Sybil resistance and trait gating, which can be done on Base Sepolia through the on-chain SignerRegistry.

This presents an interesting scenario.

Suppose we have a future airdrop where 10 wallets are running the same protocol.

These 10 wallets might be linked to a single verified identity which may make them different from 10 truly independent wallets.

This could be a very difficult way to manipulate token distribution.

It doesn't make the problem go away, however.

Defines “legitimate users.”

The Problem With "Real User" Verification

A wallet doesn't have to have a publicly known social-media presence.

There are those that choose to maintain their crypto blockchain operations distinct from their online identity.

Others might not use X, Instagram or TikTok at all.

An individual who joined the crypto market today remains a person.

This leads to an awkward position.

Assume that a protocol rewards users that have an older verified account.

It may decrease the number of fake account farming operations.

However, it might prevent true immigrants.

Suppose it requires a particular platform.

People who aren't on that platform might still miss out on the benefits of the system despite providing valuable contributions to the protocol.

Thus there arises the question:

Is what we are measuring 'real' participation, or access to a specific identity system?

Those aren't necessarily the same thing.

Sybil Farmers Can Adapt Too

There's another issue.

As a new filter comes on board a profitable system, there is an incentive for participants to avoid it.

Suspicious wallet clusters can be detected using blockchain analytics.

With behavioral analysis, wallets with similar transactions can be identified.

Creating thousands of independent accounts may be more difficult when dealing with identity verification.

None of these methods can ensure every Sybil is detected, however.

Academic studies have already examined how to do this by analysing transaction timing, funding relationships, and behaviors and structures of wallet-networks to discover groups of Sybil addresses.

That means there's no guarantee there'll be any one magic anti-Sybil button in the future.

Rather, protocols can be made of multiple signals.

Wallet history.

Transaction behavior.

Capital flows.

Account age.

Identity attestations.

Humanity proofs.

And perhaps reputation.

The more signals a protocol includes, the more difficult it will be to create a believable fake user.

But There Is a Price

The obvious benefit is better distribution.

As more and more rewards are escheated from multi-wallet operators, projects may be able to give incentives to a larger number of real users.

However, the price is complexity.

Each subsequent verification layer introduces a new dependency.

An identity provider can be dependent on a protocol.

The user may need to link-up an external account.

The rules of a verification provider might be amended.

An account may be suspended.

There may be a service interruption at a centralized service.

Then, there's another gate in the way between the user and the blockchain in what is supposed to be a permissionless app.

That does not necessarily equate to a bad system.

It just translates to the fact that there is a compromise.

The Future May Be Reputation, Not KYC

Anonymous wallets are not the only option and there is a middle ground between anonymous wallets and the traditional KYC.

Rather than users needing to provide their legal identity, future protocols may be based on reusables or reputation signals.

For example:

Establish a period of existence of an account.
Establish a person's unique verified identity.
Prove past participation without giving the user's name.
Show that multiple wallets are identified by different verified entities.
Take account of long-term actions instead of single transactions.

An important point to remember is that uniqueness does not always equal disclosure of identity.

This may be one of the major design issues with the next generation of airdrops.

Airdrops May Become Less About Volume

The previous approach was fairly straightforward:

More wallets.

More transactions.

More activity.

More potential rewards.

The world may look completely different come the future.

The system might not care as much about transactions generated by a user, but rather whether the user has a consistent and distinct user.

It would flip the farming of airdrops on their head.

Rather than rewarding for actual activity, projects could be based on credible participation.

And that might make it a lot harder to game the race.

The Bigger Question

Base's Verify Onchain experiment is interesting not simply because it attempts to reduce Sybil activity.

The bigger story is that crypto is slowly confronting an uncomfortable contradiction.

Blockchains want to remain open and permissionless.

Token distributions want to reach real people.

But proving that multiple wallets belong to different humans requires some form of identity or uniqueness signal.

Those goals don't always fit together perfectly.

The challenge for the industry will be finding a system that can answer:

"Is this one real participant?"

without necessarily requiring the user to answer:

"Here is exactly who I am."

If crypto can solve that problem, airdrops could become significantly harder to manipulate without simply turning every decentralized application into another KYC portal.

If it can't, the battle against Sybil farming may continue to move from wallets to identities — and from one set of gatekeepers to another.

And that may be the real story behind the next generation of airdrops.
