Solana: Transaction V1 goes live - 09 Sep 2026

Transaction V1 goes live on Solana on September 9, upgrading the network's core transaction format.The release gives Solana a defined milestone in the development of its transaction infrastructure. By activating a new core format, it provides a specific basis for assessing future scalability work. For investors, the upgrade provides a concrete scalability milestone that can support the existing SOL thesis. Its effect is expected to be incremental rather than transformative, so the release alone does not establish a broader change in network performance or adoption.The scope is limited to the transaction format upgrade described in the announcement, so readers should distinguish the release from broader claims about Solana's future growth.There are a lot of major changes happening soon- Next week: First step down in rent reduction- Sept 9: Transaction V1 goes live- Dropping slot time even further- October: AlpenglowThen we all meetup at Scale or Die in NovemberSolana development will never be the same
