The production of Proof of Work shares is a Poisson process, given by the Poisson probability mass function which gives the probability mass that $k$ beads are formed within a time $t$ assuming constant hashrate $\lambda$ and difficulty $x$:

$$\tag{1} \begin{align} P(t,k) = \frac{(\lambda x t)^k e^{-\lambda x t}}{k!} \end{align}

Braidpool-based Slots consensus protocols
Each bead commits to:
| Bitcoin Block header | Slots Merkle Root |
| Coinbase | timestamp | nonce | TX Merkle Root | prev block |
Where the block header is a standard bitcoin block header as expanded in the second line
and each bead commits to <Slots Merkle Root> which should be added to the <metadata>
field as described in:
https://github.com/mcelrath/braidcoin/blob/master/braidpool_spec.md
The Slots data structure is a key-value table containing:
