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 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.
The Successful 32MB Block Size Increase Paves a Path for Mass Adoption
After the Bitcoin Cash network upgraded yesterday and even before the fork, a few misguided individuals asked why there was a need to raise the block size fourfold when 8MB blocks were not filling just yet. The reason developers raised the limit to 32MB is likely because the software is perfectly capable of handling such a task in the future. Right now block size limits are set by the miner, and developers are there to help set the capacity so blocks cannot get full in the immediate future, and fees will remain low for quite some time. Unfortunately for the Bitcoin Core (BTC) network, Core developers let the block size fill beyond capacity, and fees became unreliable during the last quarter of 2017. The 32MB BCH block size adjustment ensures this will not happen to the BCH network down the road, even when transaction usage becomes as extreme as 2017's last quarter.
The Bitcoin Cash (BCH) community and developers are not afraid of forks and protocol upgrades. The May 15th upgrade is the second successful hard fork on the BCH network.
