LTCR (Layered TCR)

Basic Idea

LTCRs are composed of layers of TCRs. They replace the rather harsh “you’re either in or out” approach of TCRs, with a step-by-step increase in rights and responsibilities as the actor adds more value and stake. They smooth onboarding and help maintain actor diversity. LTCRs can be applied to problems of access control, governance, identity, reputation, and more.

How It Works: An Overview

(adapted from here)

There are clear rules for promotion, based on more stake and value added:

  • New actors enter the system with rank 1.
  • To get promoted to the next level, the actor must pass that level’s entry criteria. This criteria might include: staking more tokens, spending a minimum amount of time in the system (e.g. 3 months), or provably adding some minimum value to the system so far (e.g. have mined 5 blocks). If they pass these criteria, they are promoted, and with that promotion they gain increased rights (e.g. they can edit Bush’s bio!) or responsibilities (e.g. they must review a minimum number of pull requests).
  • If an actor no longer meets the criteria for a level (e.g. they did not fulfill their responsibilities), then they get demoted.

“Value added” is contribution to the network value. This might be in the form of proofs for which one gets block rewards, such as Bitcoin’s proof of solving a cryptographic puzzle (for network security) or Filecoin’s Proof of Space time (for storage).
