Coinbase Global Inc. is addressing user reports of delays in sending and receiving transactions on the Solana blockchain. The company has announced plans to optimize its existing systems and develop a next-generation Solana architecture to enhance support for the blockchain's growth. In a recent blog post, Coinbase emphasized the need to rethink its token listing process due to the creation of approximately one million new tokens each week. CEO Brian Armstrong proposed shifting from an 'allowed list' to a 'blocked list' model, which would incorporate customer reviews and automated on-chain data analysis to help users navigate the increasing number of tokens. This change aims to improve the user experience as the number of tokens continues to rise, making the traditional review process unsustainable.
