The Ethereum community is poised for a transformative moment with the upcoming London Upgrade, a pivotal update set to reshape the network's fee structure and introduce ETH token burns. This article delves into the key aspects of the upgrade, its implications, and how it positions ETH for potential deflation.
Key Impacts of the London Upgrade
1. EIP-1559: Fee Market Reform & ETH Burns
- Predictable Gas Fees: Replaces the auction-style gas mechanism with a base fee + tip model, stabilizing transaction costs.
- ETH Deflation: Burns a portion of transaction fees (base fees), reducing ETH supply inflation. In a thriving ecosystem post-PoS transition, burns could outpace new ETH issuance, pushing ETH into deflation.
2. EIP-3529: Gas Tokens Rendered Obsolete
- Invalidates Gas Tokens (e.g., CHI, GST2) by removing storage refunds. Holders should use or sell tokens pre-upgrade.
3. EIP-3554: Difficulty Bomb Delay
- Postpones the "ice age" for PoW mining until December 2021, aligning with Ethereum’s shift to PoS via the Shanghai Upgrade.
Timeline and Testing Phases
- Ropsten Testnet: June 24 (Block 10,499,401)
- Goerli: June 30 (Block 5,062,605)
- Rinkeby: July 7 (Block 8,897,988)
- Mainnet Target: Mid-to-late July (Tentative)

Detailed Breakdown of EIPs
EIP-1559: The Game Changer
- Dynamic Pricing: Base fees adjust automatically based on network congestion.
User Parameters:
tip: Optional miner incentive during high congestion.feeCap: Maximum total fee (base + tip) a user will pay.
- Economic Shift: ETH burns cement its utility as the primary fee token, enhancing scarcity.
EIP-3529: End of Gas Tokens
- Why It Matters: Removes refunds for
SELFDESTRUCTand reducesSSTORErefunds, breaking Gas Token mechanisms.
EIP-3554: Mining’s Last Stand
- PoW Countdown: Difficulty bomb delay gives miners until ~December 2021 before PoS takes over.
FAQs: London Upgrade Essentials
Q: Will EIP-1559 reduce gas fees permanently?
A: It stabilizes fees but doesn’t guarantee lower costs—base fees adjust with demand.
Q: How does ETH burning affect long-term value?
A: Burns reduce supply inflation; combined with PoS’s lower issuance, ETH could become deflationary.
Q: What should Gas Token holders do?
A: Use tokens pre-upgrade or sell them—post-London, they’ll lose functionality.
Q: When will Ethereum fully transition to PoS?
A: Expected during the Shanghai Upgrade (~December 2021), contingent on testing.
The Bigger Picture
The London Upgrade marks Ethereum’s next evolution, balancing fee predictability with economic incentives. As the network gears up for PoS, ETH’s deflationary potential could redefine its market dynamics.
