A gas fee is the cost of executing a transaction or a smart contract on the Ethereum network. Gas fees are paid in Ether (ETH) and are used to compensate miners or validators for processing transactions and securing the network. High gas fees can deter small transactions and make certain Ethereum-based applications costly to use, especially during periods of network congestion. As Ethereum transitions to Ethereum 2.0 and introduces more scalability solutions, the hope is that gas fees will be reduced, making the network more user-friendly.

Blockchain technology holds significant potential in healthcare by enhancing patient privacy, data sharing, and medical record security. Its decentralized, tamper-proof ledger ensures secure storage of sensitive patient data, reducing breach risks. Smart contracts enable controlled, permission-based data sharing, empowering patients to manage access while streamlining interoperability among providers. Encrypted transactions protect privacy, fostering trust. Blockchain also supports secure clinical trials and supply chain tracking for pharmaceuticals. Investment opportunities in blockchain health-tech startups are growing, particularly in companies developing electronic health record systems, data-sharing platforms, and cybersecurity solutions. Early-stage startups leveraging blockchain for interoperability and patient-centric care models are attracting venture capital, with potential for high returns as adoption scales.
