Ethereum

Ethereum

• You build Ethereum smart contracts in Solidity. It takes some effort to learn, but it gives you strong capabilities for decentralized applications.

• Ethereum has a large ecosystem with many developer tools and an active community. Some examples:

  • Truffle Suite: an Ethereum development framework that includes a development environment, a testing framework, and an asset pipeline.
  • Remix: an IDE in the browser where you write, deploy, and manage Solidity smart contracts.
  • Hardhat: an Ethereum development environment made up of components for editing, compiling, debugging, and deploying smart contracts and dapps.

Chromia

• On Chromia, you write dapps in Rell, a relational programming language for blockchains. Many developers find Rell easier to pick up than Go or Rust, which lowers the barrier to building dapps.
• Building with Rell feels much like Web2 development. To learn more, read the Rell language guide.
• Chromia ships tools and libraries that handle authentication, transaction signing, and asset management, and it keeps adding features to speed up dapp development.
• You can test with Chromia's own test framework and deploy with developer-friendly tooling.

Ethereum

• Ethereum processes only around 15–30 transactions per second, which limits how far it scales. When demand from complex smart contracts and dapps peaks, the network congests, transactions slow down, and fees rise. Both users and developers have long seen this as a major problem.

• Ethereum relies on Layer 2 solutions, such as Optimistic and ZK Rollups, to scale. These bundle many transactions into a batch and commit the batch to Ethereum as a single transaction.

Chromia

• On Chromia, each dapp runs on its own subchain, and each subchain handles roughly 500 transactions per second. When your dapp grows, you add more chains. This gives you consistently high throughput and a predictable scaling path, similar to a traditional cloud environment.

  Subchains are isolated from one another, so transactions can be processed in parallel. You scale horizontally, and your app's architecture is the only cap on how far it can scale.

  The subchain architecture is part of the platform itself, so you need little effort to take advantage of it.

Ethereum

• Ethereum charges gas fees: every smart contract execution and every transaction sent to the network costs a fee.
• Gas can be costly, and the price shifts with network demand. Here too, Layer 2 solutions are the way to reduce fees.
• As a result, users pay a fee for each action on a smart contract, and developers pay to create and update their smart contracts.

Chromia

• On Chromia, you host your dapp in a container for a fixed, predictable fee. You know your monthly operating cost in advance and can design your own fee structure for end users to cover it.

  Rather than gas fees on every action, you deal with one cost that is easier to manage.

• When usage of your dapp increases, you can add resources to its container, much as you would scale resources in a cloud environment.

Ethereum

• Ethereum revenue models are mostly transaction-based: developers write smart contracts that charge fees for their services.
• You can also set up subscriptions, advertising, or in-app purchases, but end users always pay a transaction fee in addition to whatever model you pick.

Chromia

• Because dapp operating costs on Chromia are fixed and predictable, you decide which fee model your end users see. Transactions and gas fees don't dictate your options.

• You can charge a monthly subscription, charge per feature, or charge per transaction if you prefer. You can even let users start for free and introduce charges once they see the value of your dapp. Traditional web apps do this routinely, and Web3 apps can do the same.
