According to U.Today, Cardano (ADA) scripts may soon be able to sign on-chain messages, making the network more developer-friendly and potentially more optimized than its key rival, Ethereum (ETH). This new capability could unlock new use cases for Cardano decentralized applications. Top Cardano contributor Sebastien Guillemot shared a detailed analysis of this design in a thread on Twitter.
On Ethereum and EVM networks, similar actions involve using a Merkle tree for data broadcasting. However, Cardano's UTXO-based design allows for faster message signing using scripts. These scripts can also be beneficial for Cardano's L2s and dApps, such as its EVM layer, Milkomeda. If Milkomeda's script could emit events, it could enable users to vote for the EVM layer proposals they want to support, sign up to Catalyst, and vote to reflect user preferences.
The concept of messages signed by scripts could be a game-changer for Cardano's L2 ecosystem. Better support for message signing in Cardano could make writing dApps and L2s connecting to Cardano much easier, cheaper, and safer, according to Guillemot. This development follows previous reports of potential issues with ADA crypto as the backbone of Cardano's economics, as indicated by Cardano contributor Rick McCracken.
