BLOCKS Series (BLOCKS) Guide

The BLOCKS contract is a prediction futures contract. The futures contract is Binary, meaning it will either settle at 0 or 100.

Binary Payout Guidelines

The BLOCKS contract is a prediction future on whether a block larger than 1MB (a “Big Block”) will be mined on the longest Bitcoin chain.

The definition of a “Big Block” is limited to blocks of size > 1MB through an actual base block size limit increase. Blocks with an effective size larger than 1MB due to SegWit do not apply, nor do “Extension Blocks”.

BLOCKS will settle at 100:

  • If a Big Block is mined on the Bitcoin chain with the largest hash power, and
  • If the Bitcoin chain that mined the Big Block remains the Bitcoin chain with the largest hash power for 1,512 out of the following 2,016 blocks (75%). These 1,512 blocks must have passed by the expiry date.

BLOCKS will settle at 0 if the above conditions are not met.

The above conditions may be amended with notice at any time.

Relationship with SEGWIT

BitMEX’s SEGWIT binary is independent from this contract. Both, or neither, may settle positively before the expiration date.
