Solana đề xuất giảm lạm phát và tăng lượng token bị đốt, phần thưởng staking có thể giảm một nửa trong hai năm

The Huoxing Finance report states that on August 26, asset management firm 21Shares announced that Solana is advancing two proposals, SIMD-550 and SIMD-553, aimed at reshaping the token economy by accelerating the decline in inflation and increasing SOL burn volume. SIMD-553 was approved and merged by the development team on July 20, while SIMD-550 entered the voting phase starting August 23. If both proposals are approved, they are expected to reduce SOL issuance by approximately $1.4 to $1.5 billion over six years. SIMD-550 proposes increasing the annual inflation reduction rate from 15% to 30%, shortening the time to reach the target final inflation rate of 1.5% from approximately 5.7 years to 2.8 years—advancing it from the first half of 2032 to the first half of 2029. According to the proposal’s projections, the nominal staking yield will decline from the current level of approximately 5.25% to 4.34% in the first year, 3% in the second year, and 2.25% in the third year. SIMD-553 introduces a burn fee on computational units for financial activity requests. At current network activity levels, daily SOL burn volume is projected to rise from approximately 600 to 800 SOL to between 7,500 and 9,000 SOL, valued at approximately $712,500 to $855,000 per day—still insufficient to offset the current daily inflation issuance of about $4.5 million. The reduction in staking yields will directly compress validator income. The validator voting fee structure under SIMD-553 has not yet been finalized; related costs could potentially rise up to 21 times the current level. Under SIMD-550’s projections, approximately 2 out of 738 validators may turn unprofitable in the first year, increasing to as many as 30 by the third year. Reducing issuance and increasing burn volume can help improve SOL’s long-term supply-demand structure, but does not necessarily lead to price appreciation. Solana’s current staking rate is approximately 67.93%, nearly double Ethereum’s 34.14%. One objective of lowering staking yields is to encourage capital allocation toward on-chain uses such as DeFi. However, MEV and priority fee revenues would need to increase by approximately 55% to 95% to fully offset the impact of reduced staking yields.
