Decentralized applications (dApps) use programmable smart contracts on blockchain to provide accessible services without central authority. Unlike traditional apps with centralized backends, dApps run on open-source, decentralized networks like Cardano, offering transparency and security. Cardano, a third-generation blockchain, supports scalable, secure, and interoperable dApp development. Aiken simplifies dApp development on Cardano by offering familiar syntax, an easy compiler, and clear error handling. It’s used by popular Cardano dApps like Minswap, Sundae Swap, LenFi, and JPG Store, facilitating faster and more efficient dApp creation.

Last week, core technology teams released Cardano node v.8.12.2, enhancing bootstrap peer networking. The ledger team worked on testing and updates, while Lace v.1.13 improved Trezor Safe 3 compatibility. Mithril advanced transaction certification, fixed bugs, and supported node v.8.12. Conway ledger improvements included credential restrictions and a new pricing model. Town hall 169 reported over 1bn ada in voting power. The education team prepared for the Cardano Developer course in Buenos Aires and updated content for Voltaire and Mastering Cardano.

Cardano Foundation and Crypto Carbon Ratings Institute (CCRI) released MiCA-compliant sustainability indicators for the Cardano network. This ensures compliance with upcoming EU Markets in Crypto-Assets (MiCA) regulation. Key findings include Cardano's energy-efficient protocol, annual electricity consumption of 704.91 MWh, carbon footprint of 250.73 tCO2e, and marginal power demand per TPS of 0.192 W. The report, developed using scientific methodologies, aims to enhance transparency and sustainability, setting a benchmark for blockchain networks. Leaders from both organizations emphasized the importance of sustainability and regulatory compliance in the crypto sector.

The consensus team optimized db-truncater for speed, supported debugging for bootstrap nodes, and released benchmarks for node v.8.12.0. They also merged a performance fix for node v.8.11, worked on governance action workload, and updated automations for Conway features and the Plutus cost model. The Plutus team overviewed the cost model, designed faster pattern matching, and improved documentation.
