Due to the activation of the Protocol SegWit last year, almost all the blocks currently produced a bitcoin weigh an average of 1.06 MB, and some even go beyond 2 MB. This is stated in the last report of the stock exchange BitMEX.

After the upgrade to SegWit in August 2017, although in a much slower fashion than many had hoped, the old 1MB blocksize limit is slowly starting to fade away, as our new chart with data to July 2018 illustrates.https://t.co/JClrjmBhKs pic.twitter.com/GiYxXj4rCP

“After upgrading to SegWit in August 2017, although much slower than many had hoped, the old limit of 1 MB is slowly beginning to disappear”, — analysts BitMEX.

It is worth noting that after the implementation SegWit real limit of the block size increased to 4MB, and the limit of these transactions — almost 2 MB.

In addition, since March 2018 transaction cost of bitcoin has reached a record low of 1 Satoshi per byte, and with off-grid solutions for scaling, for example, Lightning Network, the bitcoin blockchain has the potential to support millions of transactions per second.

“It is impossible to increase the size of the unit without substantial destruction of the principles of decentralization of bitcoin, at least at this stage. Lightning Network provides sufficient scalability by allowing you to reduce the payments to millibits, but until Satoshi and even substory, and to implement them in milliseconds”, — said a supporter of multi-level solutions to scale Andreas Antonopoulos.

We will remind, in March, the average unit size in the network of bitcoin fell to 515 KB, which was associated with General technical improvements of the Protocol.

Around the same time, the volume SegWit transactions in the bitcoin network has exceeded the cumulative number of transactions Bitcoin Cash, launched in August last year fork first cryptocurrency.
