Deep Dive
1. Olympia Upgrade Drafts Released (July 2025)
Overview: This is a foundational upgrade that changes how Ethereum Classic funds itself and is governed. It introduces a decentralized treasury and allows all ETC holders to vote on funding proposals.
The upgrade is defined by four Ethereum Classic Improvement Proposals (ECIPs). ECIP-1111 activates EIP-1559, which burns a portion of transaction fees and redirects another portion to a new on-chain treasury. ECIP-1112 creates the immutable treasury contract, ECIP-1113 establishes the Olympia DAO for governance, and ECIP-1114 outlines the lifecycle for community funding proposals (ECFPs).
What this means: This is bullish for ETC because it creates a sustainable, community-controlled funding model for future development. It makes the network more self-sufficient and democratic, potentially attracting builders and increasing long-term value. The fee-burning mechanism could also make ETC more scarce over time.

2. Client Implementation Progress (April 2026)
Overview: The core software for the Olympia upgrade has been completed and is running on the Mordor testnet. This is a critical step toward mainnet activation.
Development updates confirm the governance layer is active on testnet and the upgrade has been successfully implemented in three separate Ethereum Classic client software. This multi-client approach is crucial for network security and resilience.
What this means: This is neutral-to-bullish for ETC as it demonstrates serious developer momentum and reduces technical risk before the main launch. It shows the upgrade is moving from design to reality, giving the community confidence in its eventual deployment.

3. EVM Standard Compatibility (2023-2024)
Overview: Ethereum Classic maintains compatibility with the broader Ethereum Virtual Machine (EVM) ecosystem, selectively adopting upgrades that align with its proof-of-work and immutability principles.
As noted in a 2023 development blog, ETC core developers collaborated on the EVM Object Format (EOF) upgrade. This was a major ecosystem-wide improvement aimed at solving long-standing technical issues and moving toward a more stable, "ossified" codebase. ETC typically follows such upgrades after a 3-6 month security review period.
What this means: This is bullish for ETC because it ensures developers can easily port applications from Ethereum, maintaining the network's utility and relevance. It reinforces ETC's philosophy: adopting meaningful innovation without compromising its core security model.

Conclusion
Ethereum Classic's codebase is evolving through a deliberate, principle-driven process, with the upcoming Olympia upgrade representing its most significant leap in decentralized governance. How will the activation of its on-chain treasury reshape developer incentives and network growth after late 2026?
