Logos supports the development and adoption of decentralised technologies and applications around the Logos technology stack and related ecosystem components through the λPrize Program ("Program" or "λPrize").
Logos supports the development and adoption of decentralised technologies and applications around the Logos technology stack and related ecosystem components through the λ Prize Program ("Program" or "λ Prize").

The Program comprises multiple prizes (each a "Prize"), including but not limited to prizes described in the λPrize GitHub repository. Each Prize is governed by a separate prize specification, which sets out the scope, requirements, success criteria, and prize amount applicable to that Prize.
The Program comprises multiple prizes (each a "Prize"), including but not limited to prizes described in the λ Prize GitHub repository. Each Prize is governed by a separate prize specification, which sets out the scope, requirements, success criteria, and prize amount applicable to that Prize.

The Program is discretionary in nature. Logos retains sole and absolute discretion over the design of the Program, the content and nature of any prize specifications, the evaluation of submissions, the selection (or non‑selection) of winners, and the award or non‑award of any Prize. No Participant will have any entitlement to receive a Prize.

## Overview
This prize is for designing and implementing *general cross-program calls* (call mid-execution, then continue) while keeping *tail calls as the only execution primitive*. The system should let a program tail-call another program, have control return later via another tail call, and then continue execution in an *internal-only function* that cannot be invoked directly by users.
