What are the key principles that need to be followed to make blockchain secure?
Answer / Mohd. Ilyas Ansari
1. Decentralization: The network should not rely on a single point of control. 2. Transparency: All transactions and activities should be visible to all participants in the network. 3. Immutability: Once data is written to the blockchain, it cannot be altered or deleted. 4. Consensus mechanisms: These ensure that all nodes agree on the validity of transactions and blocks before they are added to the chain. 5. Strong cryptography: This provides security by ensuring that only authorized parties can access and modify the data.
