What block size limit does Kaspa target?

Kaspa targets a maximum block size of 125 KB per block. Block size is simply a cap on how much transaction data can be packed into each block the network produces. At 125 KB, the worst-case storage requirement for a full node works out to approximately 193 GB — derived from real-world transaction profiles covering standard KAS transfers and KRC-20 token transactions at the maximum pruning depth for 10 blocks per second. The 125 KB ceiling was chosen specifically to keep node storage accessible while still fitting 150–250 typical transactions per block. For anyone thinking about running a node or building on Kaspa, this limit is the single number that most directly governs both throughput capacity and long-term storage costs.
