Enabling Threshold Custody for the Lightning Network with Nested Threshold Multi-Signatures

Paul Gerhart, Nadav Kohen, Jesse Posner +1

The Bitcoin Lightning Network secures hundreds of millions of dollars, yet channel endpoints rely on vulnerable single online keys. Although threshold signatures are routinely used…

A Linear Representation for Constant Term Sequences mod $p^{a}$ with Applications to Uniform Recurrence

Nadav Kohen

Many integer sequences including the Catalan numbers, Motzkin numbers, and the Apr{Ã©}y numbers can be expressed in the form ConstantTermOf $[P^{n} Q]$ for Laurent polynomia…

Density and Symmetry in the Generalized Motzkin Numbers mod $p$

Nadav Kohen

We give a formula for the density of $0$ in the sequence of generalized Motzkin numbers, $M_{n}^{a, b}$ , modulo a prime, $p$ , in terms of the first $p$ generalized central trinomial…
