Transaction V1 is scheduled to launch on September 9, 2026, introducing a new Solana transaction format that supports larger serialized transactions and additional functionality for complex applications. The most significant change is a 3.3x increase in maximum transaction size from 1,232 bytes to 4,096 bytes, allowing developers to accommodate more complex operations such as larger multisig transactions, zero-knowledge proofs, and confidential transfers without requiring split transactions. Legacy and V0 transaction formats remain supported during this transition, with no special migration required for ordinary SOL holders. The upgrade is primarily infrastructural rather than fee-reduction focused, as Solana is separately working on rent reductions and slot-time improvements. According to Solana Foundation vice president Jacob Creech, the larger transaction format could support zero-knowledge proofs, complex multisignature instructions and other data-heavy operations, while developers must choose the V1 format for new transactions.
As reported by ASDeFi, the platform claims SOL holders can earn returns through cloud mining contracts without operating validators or purchasing mining hardware. ASDeFi offers several fixed-term contracts with different investment amounts and projected returns, including a $15 check-in contract with approximately $15.6 profit and an $100 introductory contract with approximately $108 profit. The platform supports deposits and withdrawals of over a dozen cryptocurrencies, including SOL, XRP, BTC, ETH, DOGE, BNB, and USDT. Users can start mining without purchasing equipment or bearing maintenance costs, with real-time earnings tracking and automatic withdrawals to wallets.
According to Solana Foundation, the upgrades will reshape the network's infrastructure across multiple areas including cost optimization, transaction capacity expansion, and confirmation speed improvements. Transaction V1 allows up to 64 inline accounts while not supporting Address Lookup Tables in the same way V0 transactions do, creating interesting trade-offs for developers. The additional space enables more complex operations such as zero-knowledge proofs, larger multisig transactions, on-chain signatures, and complex atomic operations that can execute as single indivisible transactions. The network has also cut its target slot time to 350 milliseconds, with separate plans for 300, 250 and 200 milliseconds, while five rent-reduction stages could eventually cut the calculation from 6,960 to 696 lamports per byte.
As reported by ASDeFi, the cloud mining platform has integrated with the Solana ecosystem, including SOL payments and token listings on Orca DEX, creating a complementary relationship with the network's infrastructure upgrades. The platform, founded in 2020 and headquartered in the United Kingdom, operates through AI-driven computing power scheduling systems combining green-energy facilities with automated yield management. Users receive $15 bonus upon registration and $0.60 daily login bonuses, with contracts ranging from $15 to $30,000 investment levels offering varying return periods from 1-day to 30-day cycles. At the time of reporting, Solana price was $101.48.
Following Transaction V1, Alpenglow consensus upgrade is currently targeted for October 2026, representing the most significant technical advancement in Solana's history. Alpenglow will tackle consensus improvements by substantially reducing the time required for Solana to reach finality, replacing important parts of the current TowerBFT and Proof-of-History-based consensus architecture. This consensus upgrade addresses a much deeper layer of Solana performance than Transaction V1, which primarily expands individual transaction capacity. The community will gather at the 'Scale or Die' conference in November to discuss future development plans and demonstrate what developers can build with the additional transaction space. Solana is aiming for about 150-millisecond transaction finality after Alpenglow activation.
