Tezos blockchain is all set to adopt one of two new protocol proposals, known as Paris A and Paris B. This follows the successful activation of the Oxford 2 protocol, underscoring Tezos’ commitment to continual improvement and innovation. The proposal details, revealed today in a joint statement by Nomadic Labs, Marigold, TriliTech, and Functori, aim to substantially boost the blockchain’s efficiency, security, and scalability.
Breaking New Ground with Reduced Block Times
At the heart of the Paris protocol proposals is the ambition to cut down block times to an impressive 10 seconds. This initiative is poised to significantly diminish latency and expedite finality, all the while maintaining the decentralized ethos and security that Tezos is known for. This move builds on the momentum gained from the implementation of the Tenderbake consensus algorithm and the introduction of validation pipelining, which previously halved block time to 15 seconds.
The reduction in block time is a testament to the rigorous optimization efforts undertaken by the development teams, aimed at identifying and resolving performance bottlenecks. Crucially, this has been achieved without imposing the need for more sophisticated and costly hardware on Tezos bakers, aligning with the platform’s principle of keeping participation accessible and affordable.
Empowering Scalability with the Data Availability Layer
Another cornerstone of the Paris proposals is the activation of the Data Availability Layer (DAL) on the mainnet. This innovative layer is designed to enhance the scalability of Smart Rollups, like Etherlink, by significantly increasing the bandwidth of data attestation beyond the confines of Layer 1 blocks. This move, thoroughly tested on Weeklynet, marks a monumental stride towards future-proofing the Tezos ecosystem’s scalability.
The DAL operates as a permissionless, peer-to-peer network that runs parallel to Layer 1, allowing for the seamless publication and retrieval of data. Its integration is a crucial step forward in bolstering the throughput capabilities of the Tezos blockchain without compromising its decentralized framework.
A Fork in the Road: Paris A vs. Paris B
The two proposals diverge primarily on their approach to Adaptive Issuance, Staking, and Adaptive Slashing — key components aimed at refining the Proof-of-Stake mechanism underpinning Tezos. Paris B proposes the immediate activation of these features upon the protocol’s adoption, marking a bold overhaul of the current staking and security mechanisms.
Conversely, Paris A offers a more cautious path, allowing bakers to later vote on these significant changes through an on-chain signaling mechanism. This provides the community with the flexibility to weigh the benefits and implications of these adjustments over time, ensuring a consensus-driven evolution of the network.
The Future of Tezos Staking
A pivotal aspect of the proposed changes is the introduction of a new staking model that aims to enhance chain security and align the economics of Tez with real-world usage. This includes a mechanism where the issuance of Tez is dynamically adjusted based on the ratio of staked Tez, promoting a more balanced and incentivized staking landscape. Furthermore, the Paris proposals envisage the establishment of a new staker role, enabling participants to contribute to security deposits without relinquishing custody of their funds.
Adaptive Slashing: Raising the Bar for Security
Adaptive Slashing, featured in Paris B, proposes a nuanced approach to penalizing misbehavior, distinguishing between inadvertent errors and deliberate attacks. This mechanism is designed to ensure a fair and proportional response to security breaches, further fortifying the integrity of the Tezos network.
A Community-Centric Approach to Innovation
The divergent paths offered by Paris A and Paris B embody Tezos’ commitment to a participatory and democratic evolution process. By providing the community with options, Tezos ensures that its trajectory remains aligned with the collective vision and priorities of its stakeholders.
As the Tezos ecosystem stands at the cusp of these transformative changes, the proposals herald a new era of enhanced performance, scalability, and security. The Paris protocol, in whichever form it may be adopted, signals a significant leap forward for the blockchain, reinforcing its position as a leading platform for innovation and decentralized applications.
