Vitalik Buterin Discusses Signature Aggregation in Blockchain

According to Vitalik Buterin, the entropy of state differences and transaction instructions in blockchain systems is fundamentally similar. However, a significant practical issue is that transaction signatures occupy substantial space. While SNARKs can reduce this space, they cannot provide fault-proof signatures. Buterin suggests that using BLS or other forms of signature aggregation could mitigate this issue by reducing the space needed for signatures. (Source)
