As Bitcoin Rejects 2MB Blocks, Dash Prepares to Implement Them

In early 2016, the masternodes that comprise Dash’s governance system voted overwhelmingly to upgrade to 2MB blocks, with 99 percent of the network in favor. Many in the cryptocurrency world saw this as a simple attention-getting gimmick, as Dash’s development priorities became focused elsewhere. However, with the recent release of Dash version 12.2, it looks like larger blocks will be implemented soon.

The version 12.2 upgrade is one step on the way to Dash Evolution, the currency’s plan to make “digital [currencies] be so easy to use your Grandma would use them.” Core developer UdjinM6 wrote of the recent update:

The most notable changes are:

  • DIP0001 implementation (which is a 2MB block upgrade);
  • Transaction fee reduction 10x (activates via DIP0001 activation);
  • InstantSend vulnerability fix (activates via DIP0001 lock in);
  • PrivateSend improvement which should allow user to have mixed funds available much faster;
  • Various RPC changes;
  • Lots of backports from Bitcoin Core and refactoring of our own legacy code which should improve performance and make code more reliable and easier to review;
  • Experimental HD wallet with BIP39/BIP44 support.

Not needed yet

Of course, larger blocks aren’t needed yet, as the currency does not process enough transactions to fill its current blocks. However, this blocksize increase follows the on-chain scaling plan announced by founder Evan Duffield earlier this year. Duffield announced that through the use of custom hardware, Dash will create a network that can scale to large numbers of transactions by using big blocks.
