On May 15, 2018, the Bitcoin Cash (BCH) network upgraded the chain’s base block size from 8MB to 32MB. The software advancement makes blocks big enough to process lots of transactions over time — which gives developers plenty of breathing room to adjust the size if it starts getting closer to its limit. Unfortunately, many misdirected individuals assume the BCH chain will start processing 32MB blocks right away, which could lead to a blockchain chain that’s much larger in gigabyte size and takes longer to download. However, this is not the case right now at all, because BCH miners process blocks that are often still under 1MB, as the 32MB code is only set to ensure the network is capable in the future.
