The Sigma update is the next step in the evolution of the protocol. It incorporates many of the improvements we’ve identified internally as well as recommendations from the community. For Benchmarkers → A reworked depos… --- ## [Update to the TIG Reward Mechanism](https://forum.tig.foundation/t/update-to-the-tig-reward-mechanism/68)

TIG operates on an Optimizable Proof of Work (OPoW) concept in which benchmarkers are rewarded in proportion to their Proof of Work, whilst being incentivized to balance different factors evenly during the PoW process. T… --- ## [Realigning Benchmark Incentives: Sub-Instance Averaging and New Difficulty Ranges](https://forum.tig.foundation/t/realigning-benchmark-incentives-sub-instance-averaging-and-new-difficulty-ranges/53)

Introduction Typically, the quality of a solution is measured by its deviation from the optimal solution. In situations where the optimal solution is unknown, the baseline algorithm establishes a reference value, ideally… --- ## [Enhanced Block Reward Function](https://forum.tig.foundation/t/enhanced-block-reward-function/46)

We are excited to announce a proposal to revise the block reward function. We encourage discussion of this new design. \\textbf{Motivation} Currently, TIG’s OPoW mechanism determines the block reward for a benchmarker i …
