ICON, the blockchain network announced today the release of version 3.0 of its mainnet. This update is significant in that ICON’s SCORE (Smart Contract on Reliable Environment), the implementation environment of ICON smart contracts, is now fully operational. The infrastructure for the SCORE development environment is the foundation for creating DApps on the ICON platform.
Along with the mainnet update, ICON also opened testnet, which allows developers to conduct tests before deploying their blockchain projects to mainnet. Additionally, the ICON team will open devnet, which supports local development environments for testing via the AWS Marketplace. Once ICON’s blockchain nodes are registered in the AWS Marketplace, developers will be able to test the ICON Service and DApps on their own private networks via the AWS cloud.
Fee Structure
The team also noted that with the function of the ICON Network expanded, it has now introduced a new fee structure. The transaction fee was fixed at 0.01 ICX, but will now be measured in a more refined way. In addition, new measures are devised for Smart Contract Executor (DApp) to reduce its burden of the transaction fee.
ICONex & ICON Tracker
ICONex, and ICON Tracker have also been updated as the new fee structure has been deployed. There are major changes in several functions including adding tokens, viewing smart contracts as well as recording and verifying data on the blockchain.
The ICON team has continued to expand the ICON ecosystem since the mainnet launch in January. They have launched Deblock and ICX Station, signed several MOUs with strategic partners, opened a developers portal, and have been releasing portions of its Yellow Paper.
