Deep dive into Coinbase Smart Wallet (2 minute read)
Coinbase has introduced a new Smart Wallet, offering a self-custodial solution that uses biometrics and a passkey system to secure transactions via a user-specific smart contract. This innovative approach ensures that users retain sole ownership of their wallet, with multiple layers of recovery provided by iCloud Keychain and Google Password Manager, minimizing reliance on intermediaries and enhancing user control and security in managing their digital assets.
Gas fees in Blockchain (1 minute read)
Gas fees on blockchains compensate validators for their computational work and help prevent DDoS attacks. Fees vary based on blockchain activity, transaction complexity, and a user's willingness to pay. Ethereum's fees are higher due to its focus on decentralization and comparatively lower computational demands, leading to network congestion. In contrast, Solana's more powerful network (more centralized) allows for faster processing and lower fees. Gas fees are not retained by Ethereum's creators (e.g., Vitalik Buterin), they are used for validator rewards and partially burned, supporting the token's value.
