What Is the Maximum Acceptable Deviation for a Block Timestamp?
In Bitcoin, a block's timestamp must be greater than the Median Time Past (MTP) of the previous 11 blocks. It also cannot be more than two hours into the future relative to the node's own system time.
This dual check provides a range of acceptable values, preventing both past and future time manipulation.
Glossar
Deviation
Variance ⎊ Deviation, within cryptocurrency, options, and derivatives, represents the squared difference between an observed value and its expected value, quantifying the dispersion of potential outcomes around a central tendency.
Median Time Past
Calculation ⎊ Median Time Past, within cryptocurrency derivatives, represents the average duration between transaction submissions and their subsequent inclusion within a block on the respective blockchain.
Timestamp
Chronology ⎊ The timestamp, within cryptocurrency, options, and derivatives, fundamentally denotes a verifiable record of event occurrence, crucial for establishing order and provenance.
Maximum Acceptable Deviation
Tolerance ⎊ Maximum Acceptable Deviation defines the pre-set tolerance limit, typically a percentage, that a trader is willing to accept between the price at which an order is submitted and the price at which it is ultimately executed.
