The team conducted the tests on May 21, and had the plan of testing bigger
block sizes in 200MB increments, until they hit either 1GB or started encountering a natural limit in the software.

With bitcoin's 1 megabyte
block size limit, Bitcoin Cash supporters claim bitcoin started to become unreliable when fees skyrocketed.
(2) It uses bucket sort to speed up the BWT encoding and decoding with time complexity O(N), so that the BWT
block size can rise to 2 GB or more to fit the big data compression.
In view of these bounds, we suggest to use an increasing
block size, which could be adaptively defined.
In this experiment, we tested the 13 images in dataset with different dividing
block sizes from 8 pixels to 32 pixels in order to analyze the effect of the
block size to the detectability and to choose a suitable
block size for further experiments.
In another analysis of a similar model [29], the agreement of the distribution of global energy extremes with a member of the GEV family was indeed good, yet large uncertainty remained on the value of the shape parameter, and no stringent test was made to make sure that the estimate was stable against changes in the
block size considered in the BM analysis.
For the image shown in Figure 1, the embedding capacity increases from 44,417 bits for the classical histogram shift method to 48,164 bits with this technique using the
block size 4 x 4.
Existing video coding standards offer variable
block size video motion estimation to improve quality of encoding.
The regulatory provisions relevant for our analysis were buffer zone distance, buffer zone distance credits (e.g., allowing smaller buffer zone distances if high-barrier tarp is used), minimum buffer zone distance, maximum application
block size and requirements for applications with overlapping buffer zones.
Simon cipher enables adaptive security by using variable key size moreover it also reduces the complexity of encrypting slightly longer message by incorporating variable
block size.
