Security

Definition ∞ Security refers to the measures and protocols designed to protect assets, networks, and data from unauthorized access, theft, or damage. This encompasses cryptographic techniques, robust wallet management practices, and the integrity of blockchain protocols themselves. A high level of security is fundamental for fostering trust and enabling widespread adoption of digital assets and decentralized systems.
Context ∞ Crypto news regularly highlights security-related events, including major hacks, the discovery of smart contract vulnerabilities, and best practices for safeguarding digital assets. The ongoing efforts to fortify systems against attackers and respond to security incidents are a perpetual narrative within the industry.
