Ethereum co-founder Vitalik Buterin said he expects growth to continue next year, but with smarter adjustments that expand capacity without new bottlenecks.

Ethereum’s Fusaka update has debuted on Hoodi, its final testnet, and is slated to bring several security and scalability improvements to the blockchain’s mainnet.

The cap on individual transactions aims to improve block efficiency, reduce DoS risks and lay the groundwork for parallel execution in future upgrades like Glamsterdam.

The rollout marks the second phase of Ethereum’s three-step roadmap, testing higher gas limits and the new PeerDAS data-sampling system.

Jump Crypto has proposed removing Solana’s fixed compute block limit to prioritize high-performance validators to handle complex blocks over suboptimal validators.

Bitcoin Core developer Jimmy Song said the Taproot upgrade hasn’t lived up to the hype, claiming it has failed to deliver on promised privacy and security features.

The passing of the project’s founder has united the community around a mission to execute his decade-long vision for the network.

Ethereum’s Fusaka upgrade arrives in November 2025, quietly boosting scalability and network resilience without changing smart contracts

The Solana overhaul is expected to decrease transaction finality to 150 milliseconds — increasing the speed by about 100-fold.

Ethereum’s largest testnet, Holešky, will be sunset in the coming weeks after two years of rigorously testing Ethereum’s most important network upgrades.

Solana’s Alpenglow protocol looks set to pass, with over 99% of cast votes in favor of the proposal that seeks to bring Solana’s transaction finality in line with Google search speeds.

Eigen Labs CEO Sreeram Kannan told Cointelegraph that Eigenlayer’s upgrade allows decentralized services to have both Ethereum-grade security and scalability.

Fusaka hard fork’s next devnet will go live on Wednesday. The first public testnet is scheduled to launch in late September.

BNB Chain also teased that it’s working on infrastructure that will allow the network to support 20,000 transactions per second.

If activated, BIP-119 could boost Bitcoin layer 2s like the Lightning Network and Ark while offering end-users safer and easier self-custody solutions.
