dApp Transaction Fees

Similar to how tokens are used in Ethereum to pay transaction fees and compensate block producers, CHR is used in Chromia to compensate block-producing nodes. In Chromia, fees are paid in CHR by dApps, though dApp developers are free to implement any policy they want, including collecting fees from users. Projects can also use CHR as reserves to peg their own tokens.

dApp Hosting Fees

Chromia offers several node classes based on resources allocated for an application to cater for the varying needs of dApps. The application hosting fee is paid in CHR by developers and is split into three components: percentage of processing time, number of transactions, and storage.

Node Incentives

CHR is used to make sure that providers have a stake in the Chromia ecosystem, offsetting incentives to collude. The locked CHR represents the provider’s stake in the Chromia economy and is used as collateral which is forfeited when nodes owned by a provider misbehave.

What differentiates Chromia from other building platforms?

Chromia uses relational databases and the platform’s Rell programming language, which is deliberately similar to modern programming languages like JavaScript and Kotlin, making it simple to learn. Rell is also more efficient than many other blockchain languages as it permits fewer lines of code, allowing developers to code 7-10 times faster.
