I am writing about an interesting project that I came across today. It is still in the testnet phase and has many shortcomings but I wanted to write a summary. The project is called Caldera.
What is Caldera?
Caldera specializes in creating high-performance, customizable, and application-specific layer 2 solutions. These specially designed blockchains (Caldera Chains) offer high transaction volume, low latency, and customizable opportunities to optimize the performance and user experience of decentralized applications. They have features such as processing hundreds of transactions per second and confirming them in seconds. Caldera Chains offer high customization options, especially with features such as address whitelist application or sustainable value creation. Additionally, they are Ethereum-compatible blockchains that can operate without the need to modify standard Ethereum smart contract code.
Caldera can deploy a rollup on the chosen chain (Ethereum, Polygon, Optimism, Arbitrum, etc.) with desired parameters. What needs to be done is integrating our application with Caldera. Moving Ethereum applications to Caldera chain usually takes about half an hour, and they also offer assistance in this regard.
TO CREATE YOUR OWN TESTNET:
Click on "login" and follow the steps:
1- Enter your email and confirm the email you receive. After clicking the link, we will return to the Caldera page and perform the following steps:
2- Enter the name of your Rollup.
3- Enter the Chain ID.
4- Click Launch Rollup.
The process usually takes about 5 minutes, but it cannot be done at the moment. Only their own testnet is funtional. Normally, if we could set it up, we could use our test chain for 12 hours. However, those who wish can try their own testnets.
CALDERA DESIGN STRUCTURE
The "EVM Settlement Layer" refers to a layer on the Ethereum network. This layer operates on the Ethereum Virtual Machine (EVM) and enables the verification and confirmation of transactions on the Ethereum network. Caldera Chains can work on all EVM-compatible chains. Most Caldera Chains have been implemented on Ethereum L1 or Polygon, but Binance Smart Chain, Aurora, Avalanche, Evmos, and most other EVM chains are also supported. To ensure the integrity and security of our platform, error proofs are placed on the chain to provide a verifiable record of all transactions and interactions.
The "Data Availability Layer" refers to a layer used on the Ethereum network. This layer manages the storage and sharing of transaction data on the Ethereum network and helps to increase its scalability. Caldera Chains use a unique architecture that separates the execution layer from the data access layer. This provides flexibility for users to directly send transaction data to the EVM settlement layer (Ethereum, Polygon, etc.) or to a private data access layer (such as Eigenlayer or Celestia), depending on their specific requirements and preferences. This design approach provides advanced scalability, security, and flexibility in managing data and transaction costs in Caldera Chains.
