Block Aggregation Consensus refers to a method used in blockchain technology to enhance transaction processing and efficiency. Instead of each transaction being processed individually, multiple transactions are grouped together into a single block.

This aggregation helps reduce the overhead associated with validating and recording each transaction separately. The consensus part means that participants in the network reach an agreement on the state of the blockchain.

Various consensus algorithms ensure that only valid blocks are added to the chain. By aggregating blocks, the network can handle more transactions at once, which leads to faster processing times and lower fees.

This approach is especially beneficial for networks dealing with high transaction volumes, as it optimizes resource usage and improves scalability. Overall, block aggregation consensus is an effective way to maintain the integrity and efficiency of blockchain systems while accommodating a growing number of users and transactions.
