Deep Dive
1. Mainnet Upgrade (17 September 2025)
Overview: COTI V2 underwent a scheduled mainnet upgrade to optimize its privacy-focused infrastructure, introducing fixes for multiparty computation (MPC) and garbled circuits-based EVM (gcEVM).
The upgrade included version 1.1.4, audited by Hacken, which stabilized the network’s core components. Key fixes addressed edge cases in transaction finality and improved compatibility with Ethereum-based tools. Node operators were required to update software, ensuring seamless adoption.
What this means: This is bullish for COTI because it strengthens the network’s reliability for confidential transactions—critical for DeFi and enterprise use cases. Users benefit from reduced downtime and enhanced security.

2. Hydrogen Hard Fork (19 October 2025)
Overview: The Hydrogen upgrade focused on backend improvements to COTI’s MPC and gcEVM systems, optimizing memory management and cryptographic randomness.
Changes included stricter validation rules for protocol operations and enhanced error-handling during smart contract execution. These updates standardized node performance under high load, critical for scaling privacy-preserving applications.
What this means: This is neutral for COTI as it prioritizes long-term infrastructure over immediate user-facing features. However, it lays groundwork for enterprise adoption by ensuring auditability and resilience.

3. COTI Earn Integration (30 September 2025)
Overview: The COTI Earn platform introduced Token Points (TPs), minted daily for on-chain actions like holding assets or participating in governance.
Built on COTI’s garbled circuits layer, the system ensures privacy for reward distribution. The SDK was updated to support TP conversions, with liquidity pools added to Carbon DeFi and PriveX exchanges.
What this means: This is bullish for COTI because it incentivizes ecosystem participation while maintaining privacy—key for attracting institutions wary of public ledger exposure.
