What’s new? Solana developers introduced the SIMD-0286 upgrade to increase the network’s block computation limit by 66%: from 60 million to 100 million computational units. It aims to increase throughput for users and developers of DeFi protocols.

What else is known? The block limit determines the amount of computational work that validators can perform in each block. Higher limits allow complex programs, such as decentralized exchanges (DEX) with order books and MEV auction systems, to run without “compute budget exceeded” errors, although validators need to cope with higher loads.

The new initiative reflects the network’s ongoing commitment to processing large volumes of transactions and improving the user experience.

When asked if the limit on Solana blocks could be removed, Anza Vice President of Core Development Brennan Watt replied that the team is continuing to discuss this possibility.

The upgrade came after the price of Solana’s (SOL) native token reached a five-month-high above $200, driven by institutional interest and growing popularity in corporate treasuries.

Some public companies have begun accumulating SOL to provide investors with indirect access to the asset through their shares, following the example of Michael Saylor’s Strategy, which has been investing in Bitcoin since 2020. It is now the largest holder of the first cryptocurrency among public companies, with a 3400% increase in its shares over five years.

Earlier this month, a number of companies announced plans to invest in SOL. For example, Asymmetric founder Joe McCann said he would raise $1 billion for a company that would form a reserve of SOL tokens. Thumzup Media received board approval to create a crypto reserve of up to $250 million, which will include the Solana token.

In addition, BIT Mining said it would raise up to $300 million to invest in SOL and transfer its current crypto reserves to this asset, while Trump’s social network Truth Social has filed an application with the US Securities and Exchange Commission (SEC) to launch an exchange-traded fund (ETF) based on a number of cryptocurrencies, including SOL.

Finally, DeFi Development Corp raised $112,5 million to purchase SOL, while it already holds 620 000 SOL on its balance sheet.

However, at the time of publication, the price of SOL had fallen to $188,4 amid a general market correction that affected major altcoins.

SIMD-0286 came about as competing blockchains started rolling out their own upgrades. Ethereum’s Pectra hard fork improved data usage in rollups, and the Bitcoin community is looking into the OP_CAT opcode to expand smart contracts and boost programmability.

Solana’s block limit was last increased by 20% on July 23 thanks to the activation of SIMD-0256, which increased throughput from 50 million to 60 million computational units.

The improvement was a step toward supporting a larger volume of transactions and increasing overall performance, enabling Solana to process approximately 1700 transactions per second (TPS).

However, developers’ needs have grown, as restaking and NFT issuance protocols, as well as decentralized physical infrastructure (DePIN) projects, require a higher block limit.

The SIMD-0286 upgrade is currently being discussed and tested. It will take effect in the upcoming software version and will be automatically activated as soon as validators update the software and approve the limit increase.

Helius Labs CEO Mert Mumtaz said that the Solana development team intends to eventually increase the block capacity to 120 million computing units.

He explained that this increase will allow developers to create more complex applications and reduce transaction fees, especially as demand grows.
