| // weeble:wobble decentralize time stamping method | ||
| // all rights reserved until further notice: | ||
| // | ||
| // WEEBLE WOBBLE is a timestamping method using bitcoin blockheight, utc | ||
| // time and a modulus function to create a unique, decentralized, yet | ||
| // verifiable two part time stamp. weeble wobble was originally described in | ||
| // a decentrailized version control proposal known as 0x20bf. The "weeble" | ||
| // component of the time stamping method is simply floor(utc/block_height). | ||
| // The wobble part of the time stamp is where weeble:wobble has more | ||
| // interesting functionality. utc modulus block_height (utc % block_height). | ||
| // utc mod block_height measures the time between bitcoin blocks and can be | ||
| // adjusted to a varying granularity depending on specification needs. | ||
| // weeble functions as a network "minute hand" and wobble functions as a | ||
| // network "second hand" (for example) but can be adjusted to milliseconds | ||
| // etc... | ||
| // verifiable multi part time stamp. weeble wobble was originally described | ||
| // in a decentrailized version control proposal known as 0x20bf. | ||
| // | ||
| // weeble=floor(utc_secs/blockheight) (integer) | ||
| // | ||
| // Combined with the most current bitcoin blockheight the "weeble" component | ||
| // of the timestamp inherits the unimpeachable and irreversibility of | ||
| // Bitcoin's proof of work and difficulty characteristics. | ||
| // | ||
| // blockheight=blocks_tip_height (integer) | ||
| // | ||
| // The wobble part of the time stamp is where weeble/blockheight/wobble has | ||
| // more interesting functionality. | ||
| // | ||
| // wobble=(utc_secs % block_height) (integer) | ||
| // | ||
| // wobble measures the time between bitcoin blocks and can be adjusted | ||
| // to a varying granularity depending on specification needs. | ||
| // | ||
| // Conceptually: | ||
| // | ||
| // weeble functions as a network "hour hand". | ||
| // block_height functions as a network "minute hand". | ||
| // wobble functions as a network "second hand". | ||
| // wobble_millis for milliseconds etc... | ||
| // | ||
| // The WEEBLE WOBBLE timestamping method may be used in many ways. | ||
| // Used with hashing functions may be particularly useful*. | ||
