Tezos Quebec Protocol Upgrade: Overview

The Quebec protocol upgrade is the 17th major update to the Tezos blockchain, activated on January 20, 2025, at block #7,692,289. Developed by Nomadic Labs, TriliTech, and Functori, the upgrade was adopted through Tezos' on-chain, community-driven governance process1 2 3.

Key Features and Improvements

1. Reduced Block Times & Quicker Finality

Block time decreased: from 10 seconds to 8 seconds.
Transaction finality: now as fast as 16 seconds, making Tezos even more suitable for high-throughput applications like payments and gaming.
Quicker confirmations: Enhances network efficiency and user experience1 2 4.

2. Enhanced Staking Mechanics & Capacity

External staking limit: Increases the amount bakers can accept from external stakers from 5x to 9x their own stake, promoting more decentralization and larger staking pools.
Staking rewards: Direct bakers now receive triple the rewards compared to delegators, encouraging more users to stake directly and contribute to network security1 5 2.

3. Refined Economic Dynamics (Adaptive Issuance Mechanism)

Issuance adjustment: Updates to Adaptive Issuance better align staking rewards with security requirements while also reducing the network's inflation rate.
Issuance bound: The mechanism now depends more directly on the overall staking ratio, preventing excessive issuance of tez and improving economic sustainability5 2 4 6.

4. Improved Delegation & Baking Power Computation

Reduced weight of delegated funds: The influence of delegated funds on baking rights computation was decreased from 50% to 33%, which increases incentives for direct staking by individuals.
Delegation rights calculation: Updated to address previous dilution and user experience issues5 7 6.

5. No Major Hardware Changes Required

The upgrade achieves these scaling improvements without major new hardware requirements for bakers or node operators, supporting a smooth transition4 1.

Governance and Community Participation

Quebec’s features and adoption reflect Tezos’ commitment to decentralized, open governance:

Proposals, voting, and testing cycles ensured wide community input and technical vetting.
The process included public testnets, vote phases (Proposal, Promotion, Adoption), and a cool-down period before going live8.

Looking Ahead

The next protocol upgrade, codenamed "R," is already being discussed, focusing on further improvements in cycle time, data availability for Layer 2 scaling, and stronger incentives for active participation3 1.

In summary: The Tezos Quebec upgrade significantly improved block times, staking rewards, and economic sustainability, all achieved through Tezos' unique on-chain governance, reinforcing the network’s position as an upgradable, efficient, and community-led blockchain1 2 3 5+1.
