Alonzo, Cardano's next protocol upgrade, will bring core Plutus smart contract capability to Cardano, delivering exciting new utility and fresh opportunities for businesses and developers. The final component of the ongoing Goguen rollout, it will start to open up whole new avenues of technical capability and decentralized finance use cases for the Cardano platform.
As with our previous three Cardano protocol updates (‘Shelley’, ‘Allegra’ & ‘Mary’) we’ll use the same HFC approach to bring Plutus – our native smart contract language and libraries – to the Cardano network.
This hard fork event is named after Alonzo Church – a US mathematician and logician who worked on the foundations of theoretical computer science. One of the reasons for naming our smart contract upgrade after Church is that Plutus Core (the Cardano smart contract language) is a variation of lambda calculus – a formal system invented by Church to prove the unsolvability of the Entscheidungsproblem.
Applying a rigorous approach based on formal methods and verification, Alonzo extends the basic multi-signature scripting language (multisig) used in Cardano Shelley to the Plutus Core language. The Alonzo ledger implements the extended unspent transaction output (eUTXO) accounting model, using Plutus Core to provide powerful scripting, and also builds on Cardano’s existing metadata, and multi-asset and native token capability. While multi-asset support allows users to create unique currencies that fuel business needs, Alonzo introduces a versatile platform for building smart contracts and decentralized applications (DApps) to work with collectibles, crowdfunding, or auctions, for example.
It’s also an update process that will require close and careful coordination with exchanges and other third parties currently integrated to Cardano.
The exchange integration team, led by the Cardano Foundation, has extensive experience in this domain. We hope that the whole upgrade process will be similarly smooth focusing on step-by-step improvements to ensure that everything works efficiently.
The team will be working closely with all exchanges to support them through the integration and to swiftly address any issues slowing them down. Exchanges have access to the Alonzo Purple testnet and also the Cardano testnet to support their integration work. However, every exchange is different and follows its own integration processes and timelines.
You’ll be able to track status on your preferred exchange, via this curated list of links to the major exchanges/third parties we’ll be working with. Once the integrations start, we’ll track progress here to keep the community updated on the status.
People holding ada on exchanges or in wallets need to have no concerns about the safety of their ada. However, it is possible that some exchange customers may experience some exchange downtime/service interruption as exchanges complete their final integration work.
Any ada holder keeping their funds on an exchange will be able to continue to be able to trade during this period. However, they may encounter issues making withdrawals and deposits temporarily during the time their exchange is updating.
If you have any concerns, we recommend you contact your chosen exchange; while we are working closely with all leading exchanges, they will be able to provide the very latest technical status. If you experience any access issues around this time on your preferred exchange platform, please first contact and log a support ticket with them if necessary. We recommend you also check their Twitter – often they will communicate status updates from there. Please also log a support request with us, using the "Submit a request" button. If we know which exchanges are having issues, we can help triage and ensure your exchange has got what it needs to complete an efficient transition to Alonzo-era functionality.
Thanks as ever for your patience during this exciting time.
