Reliquary V2

Designed and written by Justin Bebis, Zokunei and Beirao, with help from Goober and the rest of the Byte Masons crew.

Reliquary is a smart contract system that is designed to improve outcomes of incentive distribution by giving users and developers fine grained control over their investments and rewards. It accomplishes this with the following features:

1. Emits tokens based on the maturity of a user's investment, separated in tranches.
2. Binds variable emission rates to a base emission curve designed by the developer for predictable emissions.
3. Supports deposits and withdrawals along with these variable rates, which has historically been impossible.
4. Issues a 'financial NFT' to users which represents their underlying positions, able to be traded and leveraged without removing the underlying liquidity.
5. Can emit multiple types of rewards for each investment as well as handle complex reward mechanisms based on deposit and withdrawal.

By binding tokens to a base emission rate you not only gain the advantage of a predictable emission curve, but you're able to get extremely creative with the Curve contracts you write. Whether this be a sigmoid curve, a square root curve, or a random curve, you can codify the user behaviors you'd like to promote.

Please reach out to zokunei@bytemasons.com to report bugs or other funky behavior. We will proceed with various stages of production testing in the coming weeks.

V2 update notes

1. Maturity Evolution Curves: We have replaced the previous level evolution mechanism with curves to provide more flexibility and precision. The available curve options are:

   • Linear
   • Linear Plateau
   • Polynomial Plateau

2. Scalable 'Level' Number: The 'Level' number now scales with an O(1) complexity, ensuring consistent performance as the system grows.

3. Multi-Rewards with Rolling Rewarders: The V2 update now enables the possibility of multiple rewards with the rolling rewarders.

4. ABI Simplification: We have simplified ABI to streamline the interaction between the smart contracts and the user interface.

5. Gas Optimization: The V2 update brings a 20% reduction in gas consumption, resulting in lower transaction fees and improved efficiency.

6. Bug Fixes: We have addressed bugs identified in the previous version (see audit/ for more details).

7. Code Clean-up, Formatting, and Normalization: The codebase has undergone a thorough clean-up, formatting, and normalization process to improve readability and maintainability.
