Solana is preparing for an important review that could make her famous fast block chain even faster, and much easier to run.
In his research report “Crypto Monthly for September 2025” published on October 3, Global Assets Manager Vaneck says that the next AlpenGlow update of Solana marks the greatest change in the central software of the network since the launch.
The firm calls it “the best update to the Solana consensus in its history”, pointing out six key changes that together promise faster yield, lower costs and greater reliability.
For less familiar readers with the design of Solana, Alpenglow essentially changes how the thousands of network validators agree which transactions are valid. This process, known as consensus, is simplifying so that the data moves through the system more efficiently and validates can operate with less friction.
What Vaneck highlighted
Faster purpose. Today, Solana takes about 12 seconds to finish a transaction, which means confirming it permanently.
Alpenglow reduces it to about 150 milliseconds, approximately the time it takes to blink. The fastest purpose makes trades, payments and interactions of the application feel snapshot, bringing Solana closer to the capacity for response at the web level.
Vote outside the chain. The validators currently vote in each new block presenting thousands of small transactions in the chain.
That keeps the network safe but obstructs bandwidth. Alpenglow moves voting outside the chain, allowing validators to exchange votes in private and then publish a single test. This erases the space for regular user transactions and helps keep the network rates.
Simpler validator costs. Instead of paying transaction rates for each vote, the validators will present only one Validation Admission Ticket Each cycle.
This reduces costs and facilitates smaller operators execute validators, which strengthens decentralization and network safety.
Simplified communication. Solana nodes constantly share messages to stay synchronized, a process known as “gossip.”
Alpenglow reduces this background traffic, so validates spend less time and bandwidth coordinating with each other. That makes the system more stable, even when some validators disconnect.
Larger blocks. Developers plan to increase block capacity by 25% for the end of the year.
A block is a lot of transactions added to the main book. More capacity means that Solana can adapt to more transactions in each block, reducing waiting times and congestion.
The Firedance Customer. Built by Jump Crypto, Firedancer is a second independent version of the Solana validator software that is expected to be presented at the end of 2025.
Having two customers means that the network can continue working without problems if you experience problems.
It also includes a proposal called SIMD-0370which eliminates the fixed sole limit in the size of the block. That would allow the network to automatically climb with hardware faster, improving long -term performance.
P-Takens for efficiency. Current of Solana Tokens SPLUsed for most assets in the chain, they require a lot of computer power to move.
Vaneck says the new P-Take The format will reduce that demand by approximately 95 percent, releasing space in each block and increase the total transaction capacity by approximately 10 percent. This makes tokens transfers cheaper and the most efficient network under intensive use.
Together, these changes show how Solana is redesigning its infrastructure to support the next generation of finance, games and decentralized token asset applications.
What Solana engineers are building beyond that
Vaneck’s analysis captures Alpenglow’s key elements, but the White Alpenglow of Solana Labs shows that the update is even deeper than the company described. Engineers have created several changes behind the scene aimed at making Solana faster, more resistant and easier to maintain over time.
One of the most important additions is RotorA new transmission layer that replaces the existing Solana turbine system to disseminate data between validators.
The rotor transmits information more efficiently, reducing duplicate packages and shortening the time it takes for the new blocks to reach the entire network.
Change helps transactions to confirm more softly and makes the network more receptive under a heavy load.
Another improvement implies Local signature aggregationwhich allows validators to combine multiple transactions firms before transmitting them to the rest of the network.
Each transaction in Solana carries a digital signature that demonstrates its origin; The processing of each consumes the computer power and bandwidth separately. When grouping firms together, Alpenglow lightens that workload, reducing the computational cost of maintaining security.
The update is also strengthened Failure toleranceensuring that Solana continues to function, even if up to 40 percent of validators lose connectivity or disconnect temporarily. This improvement makes the network more resistant during regional interruptions or traffic peaks, which limits the risk of inactivity time.
In addition, Alpenglow reduces unnecessary “gossip” traffic: background messages are exchanged to stay synchronized. Reducing this talk not only releases bandwidth, but also helps validators in regions with slower Internet connections to participate effectively, expanding the global Solana operators.
Finally, Solana has reworked the participation of the validator through a ticket -based system That replaces thousands of small voting transactions with a single predictable admission step. This change simplifies the cost structure and reduces barriers to smaller operators, promoting a more fair participation and a stronger decentralization.
Taken together, these refinements transform Alpenglow from a simple speed update to a complete redesign of how Solana communicates internally. They show the impulse of Solana Labs to make the network not only fast in theory, but also reliable at scale, an essential step as more financial and consumer applications move in the chain.
