Olympia Upgrade

The Olympia era marks a shift from reactive maintenance to active development on the longest-running EVM and the only Proof-of-Work smart contract platform in the world.

  • EIP-1559 fee market — the most widely adopted transaction type in the EVM ecosystem, bringing predictable gas pricing and modern tooling compatibility
  • Protocol treasury — seeded by basefee revenue and voluntary contributions, funding open-source core development, infrastructure, and long-term network security
  • Fusaka EVM alignment — closes years of divergence in a single upgrade; every current Ethereum tool, library, and framework works on ETC without modification
  • Institutional infrastructure — the Proof-of-Work foundation for regulated stablecoins under MiCA and the GENIUS Act, energy grid stabilization, and ETF-compliant digital assets that regulators across the US, EU, Japan, and beyond are moving to define

What Olympia Brings to Ethereum Classic

A modern fee market, a protocol-controlled treasury, and full Fusaka EVM compatibility — delivered to the only Proof-of-Work smart contract platform in the world.

ECIP-1111

EIP-1559 Fee Market

The most widely adopted transaction format and fee market in the EVM ecosystem, now on Ethereum Classic. Dynamic gas pricing delivers predictable fees for users and applications. Fully additive — legacy transactions remain valid indefinitely. Unlike Ethereum where the basefee is burned, ETC redirects it to the protocol treasury. Miner block rewards and tips remain completely untouched.

ECIP-1112

Protocol Treasury

A protocol-controlled vault funded by basefee revenue and voluntary contributions. For the first time, institutions, developers, and network stakeholders can directly fund Ethereum Classic's core development and critical infrastructure without fielding their own team. Miners receive everything they do today — block rewards and tips remain completely untouched.

ECIP-1121

Fusaka EVM Alignment

Olympia ends Ethereum Classic's longest period of EVM stagnation, advancing the execution layer through London, Dencun, Pectra, and Fusaka in a single upgrade. Exchanges and wallets gain modern RPC compatibility and standard transaction support. Developers gain full access to every current Ethereum tool, library, and framework — one codebase, every EVM chain.

Olympia Roadmap

Five stages from consensus upgrades to permanent protocol integration.

Consensus Upgrades

Complete

Adds the most widely adopted transaction type to Ethereum Classic, ensuring continued network support by exchanges, wallets, and modern development tooling. Independent client implementations complete.

  • EIP-1559 fee market with predictable gas pricing
  • Dynamic gas limits
  • Basefee introduced — previously set to be destroyed, now funds the treasury
  • Miner tips and block rewards untouched
  • Core development and infrastructure funded without new issuance

Core Governance

Active

Governance and treasury contracts deployed. Membership-based voting. Full proposal lifecycle: submit, vote, queue, execute. Moves core development, critical infrastructure, and long-term network security from private balance sheets to an open, transparent, and permissionless framework — bringing stability to the most critical and historically unstable aspects of Ethereum Classic since the Ethereum Foundation forked to its own chain in 2016.

  • Governance and treasury contracts
  • Membership-based voting system
  • Sanctions compliance layer
  • Open, transparent funding proposals with competitive bidding
  • Free market pricing for network maintenance
  • Removes organizational overhead from the funding pipeline
  • Open to qualified professionals across the EVM ecosystem
  • Donation pipeline for stakeholders without fielding a team

Prediction Markets

Research

Futarchy-assisted governance uses prediction markets to inform treasury allocation. In a futarchy market, participants stake on the expected outcome of a proposal — if funded, does the network benefit? Market prices aggregate public opinion into a measurable signal that governance can act on. This opens protocol-level decision making to broad public participation beyond NFT holders, replacing opaque insider consensus with transparent, financially-backed forecasting. This stage requires the Fusaka EVM alignment delivered by Olympia (ECIP-1121). Research phase exploring conditional token frameworks.

  • Conditional outcome tokens
  • Market-informed proposal ranking
  • User acquisition and on-chain transaction flywheel
  • Financially incentivized public interest in protocol development
  • Additive market sentiment to complement siloed GitHub discussion threads

Treasury Distribution

Future

As Ethereum Classic's fixed-emission schedule reduces block subsidies over time, basefee revenue held in the treasury can optionally be redistributed back to miners to supplement long-term network security. ECIP-1115 defines a governance-layer smoothing mechanism — an L-curve that spreads these optional payouts across a configurable future window, reducing per-block volatility and providing a more predictable revenue profile. Critically, this is entirely optional and governance-controlled: no miner entitlement is created, consensus-layer rewards and tips remain untouched, and parameters can be adjusted or disabled without a hard fork.

  • Treasury smoothing algorithm
  • Smoothing allocation amount experiments
  • Multi-algorithm modeling for stable miner security budget through ECIP-1017 emission reduction events
  • Miner impact analysis

Protocol Integration

Future

Permanent consensus integration of proven governance mechanisms. Moving governance from contract layer to protocol layer.

  • Consensus-level governance
  • Immutable treasury rules
  • Long-term sustainability

Frequently Asked Questions

What happens if I don't upgrade?

If you do not upgrade before the Olympia activation block, your node will stop following the canonical chain. You will need to upgrade and resync from the fork point. Exchanges, wallets, and services running outdated clients will be unable to process transactions on the post-Olympia chain.

Will my miner rewards change?

No. Block rewards and tips remain completely untouched. The Olympia upgrade redirects the EIP-1559 basefee — a value set to be destroyed — to the protocol treasury. This is entirely separate from miner rewards.

When is the activation block?

The exact activation block will be announced after the Olympia Upgrade core developers call. All client implementations will release Olympia-compatible versions well before activation. Outreach will occur with all major network stakeholders to assure a smooth upgrade.

Can I roll back if something goes wrong?

Olympia is backward compatible, but nodes must remain on current client versions to follow the canonical chain. In the unlikely event of an issue, emergency releases would be published promptly. All clients have been thoroughly tested by the same team that has delivered every Ethereum Classic network upgrade since 2016 — 14 hard forks without a chain split. Core-Geth is actively maintained through the Olympia upgrade, and Fukuii carries broader test coverage than any previous ETC client. Olympia also marks a fundamental shift from reactive maintenance to active development — so the network's core teams are responsive, engaged, and building forward.
