Solana developers have introduced a significant upgrade proposal, SIMD-0286, aimed at increasing the network’s block capacity by 66%.
This change would raise the block compute limit from the current 60 million Compute Units (CUs) to 100 million CUs, enabling higher transaction throughput and improved decentralised application (dApp) performance on the platform.
Block capacity determines the amount of computational work that validators can process within each 400-millisecond Solana block. Increasing this limit enables the network to process more transactions per block, which is crucial for scaling. The SIMD-0286 upgrade is a continuation of Solana’s efforts to boost performance, following previous increases such as SIMD-0207 and SIMD-0256 that raised capacity first to 50 million and then to 60 million CUs.
🚨BREAKING: @Solana is set to further raise block capacity from 60M to 100M CUs under SIMD-0286, a 66% increase. This follows yesterday’s 20% jump to 60M at epoch 822. According to core engineer @anza_xyz, the upgrade could be implemented today pic.twitter.com/6tGJCHJfit

The proposed block limit increase is expected to benefit high-demand use cases, including decentralized finance (DeFi), non-fungible token (NFT) minting, and decentralized physical infrastructure networks (DePIN). These applications often require intense computational resources, and the higher block capacity should help reduce transaction delays and limit errors like “compute budget exceeded.”
Solana currently supports over 2,000 transactions per second (TPS) on its mainnet. With SIMD-0286, this throughput could be further improved. However, the upgrade also raises concerns about network stability and the demands on validator hardware. Validators will need to handle increased computational loads, which could affect decentralization if smaller nodes cannot keep up.
The proposal for SIMD-0286 is now open for testing and community feedback on GitHub, with ongoing discussions among validators and developers regarding its implications. It requires thorough testing and consensus from validators before being rolled out on the mainnet. Once activated, it will enhance Solana’s scalability through block capacity improvements, positioning it to compete with other blockchains like Ethereum that use rollups. This upgrade aims to maintain Solana’s status as a leading platform for dApps and DeFi projects.
Meanwhile, Hong Kong-based Click Holdings Limited is diving into the crypto space with plans to build a treasury worth up to $100 million in Bitcoin (BTC) and Solana (SOL).
