The Ethereum Foundation has set a new long-term goal: make the Ethereum base layer resistant to potential quantum-computing attacks by December 2029.

At the same time, developers have outlined key changes for the future Hegotá upgrade, which is expected to prepare Ethereum for its next major stage of technical development.

Why Is Ethereum Already Thinking About Quantum Computers?

Modern cryptocurrencies rely on cryptography to prove ownership of assets and authorize transactions.

Today’s computers are effectively unable to brute-force private keys used by major blockchain networks.

However, sufficiently powerful quantum computers could theoretically threaten some of the cryptographic algorithms used in modern blockchains.

That level of technology does not yet exist, but the Ethereum Foundation does not want to wait until the threat becomes immediate.

Developers are preparing in advance.

Some working scenarios consider the possibility that so-called Q-day — the point at which quantum systems become powerful enough to pose a real cryptographic threat — could arrive around 2030, although many estimates place it later.

What Will the Hegotá Upgrade Change?

One of the key features under discussion is Frame Transactions — EIP-8141.

The idea is to make Ethereum accounts much more flexible.

Today, a standard Ethereum account is closely tied to a specific type of cryptographic signature.

Frame Transactions could allow different parts of a transaction to be programmed separately, including:

transaction authorization;
fee payment;
execution logic;
different authentication methods.

In the future, this could make it possible to change the signature mechanism of an account and migrate to quantum-resistant cryptography without forcing users to move all of their funds to a completely new address.

Users May Be Able to Pay Gas Without Holding ETH

Frame Transactions could also introduce another major convenience.

Today, a user may hold, for example, 1,000 USDT in an Ethereum wallet but have no ETH.

In that case, the user cannot send the USDT because Ethereum gas fees must be paid in ETH.

The proposed architecture could allow another account or application to pay the gas fee on behalf of the user.

For example, a service could charge the user in USDT and handle the ETH gas payment itself.

For ordinary users, this could make Ethereum significantly easier to use.

Ethereum Also Wants Stronger Censorship Resistance

Another major proposal for Hegotá is FOCIL — EIP-7805.

Its goal is to reduce the chance that a large block producer can exclude certain valid transactions.

A dedicated group of validators could require valid transactions from the public mempool to be included in a block.

So Ethereum is working not only on quantum resistance, but also on making the network infrastructure more independent and censorship-resistant.

Why Start Working on This Now?

A blockchain cannot switch to completely new cryptography with a single update.

Several layers would need to change, including:

user accounts;
validators;
consensus mechanisms;
data processing;
wallets and applications.

That is why the Ethereum Foundation wants to complete the transition before a quantum threat becomes urgent.

Under the current roadmap, quantum resistance should eventually cover Ethereum’s execution, consensus and data layers by the end of 2029.

What Will Happen to Existing Wallets?

For now, users do not need to do anything.

Hegotá is still under development, and a full transition to post-quantum cryptography would happen gradually through multiple upgrades.

One of the main goals is to make sure existing accounts can move to new authentication methods without users having to urgently create new wallets and manually transfer all their assets.

This is especially important given the enormous amount of value currently held across Ethereum, DeFi protocols and staking systems.

Why This News Matters for the Entire Crypto Market

Most crypto headlines focus on price movements.

This story is different because it concerns something much more fundamental: the long-term security of blockchain infrastructure.

Ethereum is effectively preparing for a technology that is not yet an immediate threat, but could eventually change modern cryptography as a whole.

It shows how far ahead major blockchain networks need to plan.

What Does This Mean for IXIDE Users?

For IXIDE users, this news does not change the current process of exchanging Ethereum or ERC20 tokens.

When making transfers, it is still important to check:

the network;
the wallet address;
the amount;
the transaction fee;
the transaction status.

In the long term, however, upgrades like Hegotá could make Ethereum easier and safer to use.

The possibility of paying transaction fees without needing to separately hold ETH could be especially useful for everyday users.

What Happens Next?

Hegotá is expected to become one of the next major stages of Ethereum development after the Glamsterdam upgrade.

The Ethereum Foundation is working on several areas at the same time, including:

post-quantum security;
faster transaction finality;
privacy;
blockchain state management;
zkEVM development.

To meet its long-term targets, Ethereum will likely need to continue releasing major upgrades at a relatively fast pace.

IXIDE Opinion

At IXIDE, we believe this news is interesting because it is not about the current ETH price, but about the future of the entire network.

Crypto infrastructure needs to remain secure not only against today’s technology, but also against future advances in computing.

If Ethereum can transition to quantum-resistant mechanisms in advance while also simplifying gas payments and account management, it could become one of the most important technical upgrades the network has seen in years.

For users, however, nothing changes today — these upgrades are still under development, and existing Ethereum transactions continue to work as usual.
