Tezos launches its Ushuaia upgrade, boosting Data Availability Layer bandwidth to 10MB/s for data-intensive applications.
Blockchain network Tezos successfully deployed its 21st protocol upgrade, named Ushuaia, following an on-chain governance vote by its network stakeholders and validators.
The upgrade, developed by Nomadic Labs, Trilitech, and Functori, marks a major milestone in the network’s scalability roadmap. This technical advancement scales the network’s Layer 1 data availability bandwidth to 10MB/s, representing a fifteenfold increase over its previous capacity.
Consequently, the network can now seamlessly process hundreds of thousands of transactions per second without facing data publication bottlenecks.
The upgrade directly resolves the data limitations that previously restricted high-throughput applications from operating efficiently on the network. By optimising software and adjusting protocol parameters without increasing hardware demands, it eliminates congestion points for decentralised applications.
Furthermore, Ushuaia introduces dynamic attestation to accelerate operations like withdrawals on the Etherlink EVM layer. It also deploys a quantum-resistant signature scheme and enshrines liquid staking features onto its testnet for community evaluation.
Yann Régis-Gianas, Head of Engineering at Nomadic Labs, said: “With Ushuaia, Tezos Layer 1 does exactly what a modern settlement layer should do: increase data availability for the applications arriving with Tezos X, while preparing the cryptographic migration path long before quantum risk becomes urgent.
Arthur Breitman, co-founder at Tezos, said: “Among other improvements, Ushuaia marks the first step in a timely transition to post-quantum cryptography, a change every blockchain will need to undergo.”
