Proposal GP006 aims to address the underutilisation of shards on the network that is currently causing unnecessary resource expenditure and slowing down block production. By temporarily eliminating these shards until the launch of Zilliqa 2.0’s X-Shards, we aim to improve both decentralisation and cost-efficiency on the network, while ensuring that every participant, regardless of their computation power, has a fair opportunity to earn rewards.
We will adjust mining rewards so as to maintain approximately the existing reward structure once we have removed shards, which will have the side effect of significantly reducing the block time; we will take the opportunity to adjust the reward structure to allow miners to run their nodes from more widely distributed locations, allowing for cheaper hosting.
The Zilliqa mainnet has traditionally operated with four shards, which has led to underutilisation, slowing down block production and causing unnecessary resource expenditure for both validation and hosting. Therefore, we propose a temporary elimination of these shards until the launch of XShards as part of Zilliqa 2.0.
ZIP-23 presents a comprehensive strategy to not only eliminate the underutilised shards, but also address the existing disparities in miner rewards. The objective is twofold: to harmonise rewards between miners who co-sign proposed blocks rapidly and those who are slower, and to completely remove the current shards until the introduction of X-Shards with Zilliqa 2.0.
The proposal recognises the fact that the discrepancy in rewards is not due to how fast miners solve the PoW puzzle, but rather how swiftly their votes on proposed blocks to the leader of the pBFT consensus are received and is intended to balance this.
The proposed approach will facilitate miners in diversifying the locations of their nodes, moving away from the current core of the Zilliqa network. This, in turn, provides miners with the opportunity to utilise more economical hosting solutions.
We anticipate that the proposed changes will lead to a reduction in rewards for faster miners and an increase for slower ones. Recognising the benefits of efficient mining to the network, our proposal doesn’t aim to completely level the reward discrepancy. Instead, it seeks to reduce the disparity and promote a more equitable reward system while retaining the motivation for high-performance mining.
The proposed approach continues to place value on the contribution of the more efficient miners, whilst providing an avenue for slower miners to earn improved rewards.We believe that this change will not only enhance the decentralisation of the network but will also encourage cost-effective practices by enabling miners to host nodes in diverse locations without compromising their returns.
- For - implement the proposal
- Against - keep the reward structure (and block times) as they are.
