This thread is an attempt to gather information about scriptless scripts and update when new research material becomes available.

Some of those are also written up here, starting from the ground up:

github.com

mimblewimble/grin/blob/master/doc/contracts.md

This document describes smart contracts that can be setup using Grin even
though the Grin chain does not support scripting. All these contracts rely
on a few basic features that are built in the chain and compose them in
increasingly clever ways.

None of those constructs are fully original or invented by the authors of this
document or the Grin development team. Most of the credit should be attributed
to a long list of cryptographers and researchers. To name just a few: Torben
Pryds Pedersen, Gregory Maxwell, Andrew Poelstra, John Tromp, Claus Peter
Schnorr. We apologize in advance for all those we couldn't name and recognize
that most computer science discoveries are incremental.

# Built-Ins

This section is meant as a reminder of some crucial features of the Grin chain.
We assume some prior reading as to how these are constructed and used.

## Pedersen Commitments

All outputs include a Pedersen commitment of the form `r*G + v*H` with `r`
