On June 4th 2024, the Tezos blockchain successfully activated the Paris protocol upgrade proposal at block 5,726,209. This marks a new era for the chain, with significant effects on its Proof-of-Stake model in three key areas: Faster Finality, Higher Scalability, Stronger PoS.
We will focus this guide on the last point, and describe the new PoS mechanism brought by this upgrade, as it has a significant impact on the staking rewards that can be accrued on the blockchain.
For this upgrade, a new mechanism called “Adaptive Issuance and Staking“ has been implemented, which sets a new calendar for the inflation rewarded to bakers as well as a new staking system, adapting the economics of Tezos to fit better with real-world usage.
Adaptive Issuance means that staking rewards are no longer issued at a fixed (constant) rate, but instead will adjust depending on the share of total supply involved in staking. At the end of each cycle, the protocol adjusts reward values automatically, in order to bring the staked funds ratio towards a chosen target (50% in Paris).
Staker has also been introduced as a new role along with Adaptive Issuance. As a reminder, Tezos previously only allowed bakers (or delegators) to receive rewards through their assets. Like delegators, stakers delegate consensus and voting rights to a chosen baker. Unlike delegators, they can stake funds, which count towards their baker’s staking balance. Staked funds are frozen, and subject to slashing if the baker misbehaves.
With the new mechanism, staked funds are worth twice as much as delegated funds for the computation of consensus rights. Rewards arising from stakes are accrued automatically by the economic protocol for both bakers and stakers alike.
The other side of this coin is Adaptive Slashing. As stakers are subject to slashing if their chosen bakers misbehaves, the effect of penalties extends to more users. It becomes important then to differentiate between sporadic incidents arising from involuntary errors, from malicious, sustained attacks. This new mechanism then introduces changes in how penalties for double-signing consensus operations are computed, adapting to the fraction of the total attesting stake involved (more stake, higher penalties).
We recommend all delegators to familiarize themselves with the changes implemented in this Tezos Paris upgrade: Quick Start Guide for Adaptive Issuance.
On our side, Chorus One has implemented the Paris upgrade and is now accepting stakers. Through the previous guide, you will be able to complete the steps needed to start staking on Tezos and avoid any diminished rewards due to the new issuance model.
