Native tokens are the exclusive means to pay gas fees on blockchains, ensuring security, consistency, and the dominance of the blockchain’s primary currency. Here’s why non-native tokens aren’t used:

Universal Acceptance 🌍: Allowing only one token for gas fees simplifies the process for users and validators. It ensures predictable transaction costs and stable validator earnings. Multiple tokens could lead to confusion and unpredictable revenues, which would destabilize the network.

Security 🔒: Native tokens play a crucial role in maintaining blockchain security. If non-native tokens were allowed, their price volatility could be exploited, potentially compromising the entire network. For instance, manipulating the price of a non-native token used for gas fees could allow attackers to validate transactions at minimal cost, threatening blockchain integrity.

Native Token Dominance 👑: Maintaining the hegemony of the native token is vital for a blockchain’s ecosystem. Allowing non-native tokens, especially stablecoins, could diminish the importance of the native token, leading to its obscurity and weakening the blockchain’s value proposition.

In conclusion, while it might seem beneficial to use any token for gas fees, the risks to security, standardization, and native token prominence make it clear why only native tokens are accepted. 🛡
