Ethereum’s long-anticipated upgrade to ETH 2.0 has become a well-known narrative in the blockchain space—progressive, promising, but slow. While the community waits for scalability solutions like sharding and proof-of-stake to fully mature, Vitalik Buterin (affectionately known as V神) is exploring bold, short-term innovations to bridge the gap. Two recent proposals have stirred significant discussion: a temporary data-layer integration with Bitcoin Cash (BCH) and a relay registration burning mechanism aimed at enhancing privacy and reducing spam transactions.
These moves aren’t just technical tweaks—they signal Ethereum’s adaptive strategy in a competitive ecosystem where performance, privacy, and user trust are paramount.
Bridging the Gap: Could BCH Become Ethereum’s Data Layer?
One of the most surprising suggestions from Buterin is the idea of leveraging Bitcoin Cash as a temporary data layer for Ethereum until ETH 2.0 reaches full maturity.
Why Does Ethereum Need a Data Layer?
To understand this proposal, it's essential to distinguish between computation and data storage on blockchains:
- Computation Layer: This handles complex operations like executing smart contracts or minting tokens—precisely what Ethereum excels at.
- Data Layer: This stores large volumes of transactional or metadata (e.g., on-chain messages, NFT metadata, or even "on-chain graffiti" trends).
While Ethereum’s computation is powerful, its throughput for handling raw data remains limited. Current network congestion shows this clearly: average TPS hovers around 7, and unconfirmed transactions frequently spike—echoes of past crises like CryptoKitties clogging the network in 2017.
ETH 2.0 promises up to 10 MB/sec of data throughput via rollups and sharding—but that future is still unfolding.

Why Bitcoin Cash?
Buterin identified several criteria for a suitable interim data layer:
- High data capacity
- Low transaction fees
- Proven cross-chain verification capabilities
Enter Bitcoin Cash, which offers:
- 32 MB blocks every 10 minutes—significantly higher than Bitcoin’s 1–4 MB
- Extremely low fees, making bulk data publishing affordable
- Already supports mechanisms to verify BCH transactions on Ethereum
Although BCH’s 10-minute block time isn’t ideal for real-time applications, ongoing developments like the Avalanche consensus protocol could strengthen instant confirmations, reducing reliance on deep block confirmations.
Alternative chains like Ethereum Classic (ETC) were considered—but ETC’s smaller data capacity (~8 KB/s) and more complex verification logic made it less appealing.
“This isn’t a merger or permanent integration,” emphasizes a core developer familiar with the discussions. “It’s a pragmatic stopgap—like renting cloud storage while building your own data center.”
Is This Proposal Set in Stone?
No. The idea remains a conceptual suggestion, not an official roadmap item. Even if implemented, it would only be active until ETH 2.0’s native scaling solutions stabilize.
Still, the mere suggestion sent ripples through the ecosystem.
Criticism and Concerns
Critics argue that relying on BCH introduces new risks:
- 51% attack vulnerability: BCH uses the same SHA-256 mining algorithm as Bitcoin. If Bitcoin miners redirected hash power, they could theoretically overpower BCH’s network cheaply.
- Security asymmetry: Studies show attacking BCH costs dramatically less than attacking Ethereum, creating a potential weak link.
Tuur Demeester, founder of Adamant Capital, voiced skepticism:
“Why tie Ethereum’s fate to a chain with such low attack resistance? It creates a liability.”
Moreover, this move raises existential questions for Ethereum Layer 2 projects—many of which were designed as interim scaling solutions using rollups, state channels, or plasma.
If Ethereum can temporarily outsource data storage to an established chain like BCH, does that reduce urgency for Layer 2 innovation?
Not necessarily. Most experts agree that Layer 2s remain critical for computation scaling, while BCH-style integration focuses solely on data availability. They serve different purposes—but the signal is clear: Ethereum won’t wait indefinitely for perfect solutions.
Enhancing Privacy: The Relay Registration Burning Mechanism
Beyond scalability, Buterin has turned attention to privacy and spam resistance in decentralized applications.
His second major proposal involves a relay registration and fee-burning system, designed primarily for second-layer networks (like those supporting meta-transactions or privacy-preserving protocols).
How It Works
The mechanism operates as follows:
- Users send transactions through relays—intermediary nodes that broadcast messages to the mainnet.
- Each transaction includes a fee paid to the relay.
- A smart contract burns (destroys) a portion of the fee, distributing the remainder to the relay operator.
- Relays can accept ETH or ERC-20 tokens.
This design serves multiple purposes:
- Spam deterrence: Since part of every fee is burned, attackers face escalating costs for flooding the network.
- Privacy enhancement: By decoupling sender addresses from direct blockchain broadcasts, user identities are obfuscated.
- Incentive alignment: Honest relays earn sustainable rewards; malicious ones risk reputation and lost income.
Crucially, this isn’t about enabling full anonymity—it’s about improving privacy within regulatory-compliant boundaries.
Privacy vs. Anonymity: A Critical Distinction
There’s widespread confusion between privacy, pseudonymity, and anonymity—especially in crypto circles.
Let’s clarify:
Imagine someone buys rat poison at a village store:
- Privacy: Only the shopkeeper knows who bought it. Identity isn't public.
- Pseudonymity: The buyer uses a fake name. Still traceable under investigation.
- Anonymity: The buyer wears a mask, avoids cameras, says nothing. No traceable clues exist—case goes cold.
Bitcoin and most cryptocurrencies offer pseudonymity, not true anonymity. Addresses aren’t tied to names—but with enough chain analysis, patterns emerge.
True anonymity—like that offered by Monero or Zcash—raises red flags for regulators due to misuse risks in illicit markets (e.g., Silk Road).
But here's the key insight:
We should protect privacy—but not at the cost of accountability.
Blockchains enabling completely untraceable transactions risk becoming tools for money laundering, terrorism financing, or illegal content hosting (e.g., extremist manifestos embedded in on-chain data).

Ethereum’s approach reflects this balance: enhance user privacy through technical means (like relay obfuscation), but retain enough auditability to comply with legal standards.

Frequently Asked Questions (FAQ)
Q: Will Ethereum actually integrate with Bitcoin Cash?
A: Not permanently. The idea is a temporary measure to boost data capacity until ETH 2.0 matures. No official implementation has been confirmed yet.
Q: Does this make Ethereum less secure?
A: Potentially, if BCH suffers a 51% attack during integration. However, since only data would be stored on BCH—not value transfer—the risk is limited to data integrity, not fund loss.
Q: How does the relay burning mechanism improve privacy?
A: It hides users’ IP addresses and wallet links by routing transactions through third-party relays. Partial fee burning discourages spammers from overwhelming these relays.
Q: Are anonymous cryptocurrencies dead?
A: Not entirely—but mainstream adoption requires compliance. Projects offering selective transparency (e.g., auditable privacy) may thrive where pure anonymity fails.
Q: What happens to Ethereum Layer 2 projects if BCH is used?
A: Their role evolves. Data layer outsourcing doesn’t replace computation scaling. Rollups and channels will still be vital for high-throughput dApps.
Q: Is Ethereum moving toward full anonymity?
A: No. The focus is on privacy-enhancing technologies within legal frameworks—not complete anonymity, which poses regulatory and ethical challenges.
Final Thoughts: Pragmatism Over Perfection
Vitalik Buterin’s recent proposals reflect a shift toward pragmatic innovation—leveraging existing infrastructure to solve urgent problems while long-term upgrades develop.
Whether the BCH collaboration materializes or not, the message is clear: Ethereum will explore all viable paths to maintain its position as the leading smart contract platform.
And when it comes to privacy? Expect progress—not revolution. Ethereum aims to protect users without shielding criminals—a delicate but necessary balance in the age of global regulation.
