Placeholder team publishes an analysis of the decentralization and sustainability challenges of Solana's blockchain network validator set

According to Bijie.com, the Placeholder team issued a report to analyze the decentralization and sustainability challenges of Solana's blockchain network validator set. Solana is currently facing the problem of concentrated pledges by validators, and most pledge rights are concentrated in a few nodes. This stems from the positive feedback loop of the equity-weighted reward mechanism, and inflation rewards further aggravate this imbalance. To alleviate this situation, the article recommends optimization through multiple mechanisms in the Solana core protocol. As a newly adopted high-performance consensus mechanism, Alpenglow mainly focuses on performance improvement, but also introduces several economic designs that affect the fairness of the validator set, such as setting the upper limit of active validator and adjusting the voting cost. At the same time, dynamic inflation plans (such as SIMD-228 proposal) and optimized VAT (voting account transactions) pricing are also adjustable optimization paths. Through the comprehensive optimization of these mechanisms, a more balanced staking distribution of verifiers is expected to be achieved, thereby improving the overall decentralization level of the network.
