Qtum Improvement Proposal # 26 Reduce Block Spacing This Qtum Improvement Proposal (QIP) describes changes in blockchain parameters and logic to reduce target block spacing (the average spacing between blocks).
From launch, Qtum has used a target block spacing (a configuration parameter) of 128 seconds. Target and difficulty are adjusted for every block to maintain the average 128 seconds block spacing, with considerable variance due to the randomness needed for decentralized consensus.
This proposal would change parameters and perhaps other logic, to reduce the average block spacing to 16 seconds if there are good results after testing/tuning, or perhaps 32 seconds. The consensus algorithm currently evaluates every UTXO at 16-second intervals, targeting a solution (publishing a block) after 8 intervals, or 128 seconds. A block could be published after the first interval (in 16 seconds) or occasionally, long after the target of 8 intervals.
New block headers and new blocks can be proposed continuously on the network, but consensus logic validates with a 16-second granularity, meaning blocks are validated and time-stamped with 16-second granularity according to the interval spacing.

Qtum Updates for September The month of September continued with Qtum’s Stake-A-Thon and the Qtum DeFi Grant Program! If you haven’t heard about the DeFi grant program, Qtum has put up to 5 million dollars for the development of DeFi projects on the Qtum blockchain, and we’ve received a nice array of applications already. So, why is Qtum a great choice for DeFi?
Qtum users can enjoy the benefits of high TPS and low transaction fees. Qtum blockchain also offers more scalability by having the capability of changing parameters of the blockchain without the need for a hard fork. If you have an awesome development team, or you’re a one-person show that wants to build something transformative, check out the link below and bring your best DeFi solution to Qtum.
