Solana is approaching a pivotal moment in its evolution as it prepares for one of the most consequential network upgrades. After a long period recognized for its speed and low fees, the network has also faced criticism around stability, validator performance, and long-term scalability. This upcoming upgrade aims to directly address those concerns that could redefine SOL’s role in the blockchain ecosystem.

Solana is preparing for one of its most significant upgrades with Alpenglow, a consensus overhaul that replaces both Tower BFT and Proof of History (PoH) to achieve sub-second finality. In an X post, Delphi Digital revealed that the upgrade will introduce two protocol components.

At the core of this upgrade is Votor, which would replace the Tower BFT’s incremental voting rounds with a lightweight vote aggregation model.  Validators can aggregate votes off-chain before committing finality, allowing the block to be finalized in one or two confirmation rounds rather than multiple chained rounds. Due to this, the theoretical finality would drop down to the 100-150 millisecond range, representing roughly a 100-fold reduction from its original 12.8 seconds.

Furthermore, Votor would achieve this through two concurrent finalization paths: Fast Finalization triggers when a proposed block gains 80% or more of the total stake approval in the first round, and instantly finalizes. After, Slow Finalization would kick in when the first round reaches 60 to 80%, which will require a second round to exceed 60% before the block is finalized. Both paths operate in parallel and will ensure finality is achieved even when under partial network participation.

The other core of this upgrade is Rotor, which has been redesigned to rework the SOL block propagation layer. Meanwhile, the original Turbine gossip network relied on multihop relays with variable latency. Rotor will introduce stake-weighted relay paths that would prioritize bandwidth-efficient propagation, meaning high-stakes validators with reliable bandwidth will become the key relay points.

In simulation, block propagation can occur in as low as 18 milliseconds under typical bandwidth conditions. This upgrade is expected to roll out gradually, with initial activation anticipated in early to mid-2026.

The Kobeissi Letter has reported that the Solana on-chain spot volume reached $1.6 trillion in 2025, officially overtaking all off-chain exchanges except Binance. According to data from Jupiter Exchange, SOL on-chain volumes have surged from 1% of total volume to a massive 12% since 2022.

In 2025, SOL officially surpassed Bybit, Coinbase Global, and Bitget in total trading volume. Meanwhile, the Binance share has declined from 80% to 55% since 2022. This shows that the crypto activity is rapidly moving on-chain.

Aave founder and CEO Stani Kulechov has responded to recent governance tensions within the Aave ecosystem, outlining a strategic plan to address operational control concerns and accelerate long-term growth. The controversy followed a DAO vote on whether the community should assume full control over the protocol’s brand and front-end assets. The proposal was decisively rejected—with 55% voting against, 41% abstaining, and just 3.5% in favor—highlighting persistent questions around value capture and alignment between Aave Labs and token holders.

In a post on Friday, Kulechov framed the present moment as a crossroads for Aave, emphasizing that the protocol’s growth cannot be limited to its current crypto-native lending products. He sees enormous potential in expanding into real-world assets (RWAs) and institutional markets, projecting that Aave could ultimately support a $500 trillion asset base and onboard tens of millions of users through the Aave App. 

Kulechov said:

Today, most of Aave’s lending is concentrated around ETH, BTC, or leverage-driven looping strategies correlated with crypto market cycles. When I started Aave (originally as ETHLend) in 2017, the vision was to use smart contracts to power lending across virtually all asset classes and use cases.

A core aspect of this strategy is the upcoming Aave V4, a modular architecture designed to integrate new lending models and asset classes safely. The design allows innovation without compromising protocol integrity, enabling both crypto-native and RWA-backed use cases while creating a developer-friendly environment to encourage innovation.

Addressing operational concerns, Kulechov stressed that mainstream consumer-grade products needed to onboard millions of users should be developed by independent, highly autonomous teams on top of the permissionless Aave Protocol rather than funded or controlled directly by the DAO. This approach ensures rapid execution while allowing the protocol to benefit from increased usage and revenue.

Kulechov said:

World class consumer products are built by highly opinionated teams with the autonomy to move quickly. While decentralized governance works well for protocol economics, it is not suited for product-level decision making.

Kulechov also pledged to share revenue generated outside the protocol with token holders and confirmed that upcoming proposals will include clear guardrails for branding and revenue alignment. In his concluding notes, Kulechov reinforced his belief in Aave’s potential while also appealing for collaboration to drive the protocol and its native token’s success.
