Delphi Digital: Solana is preparing to undergo the Alpenglow upgrade, with theoretical confirmation time reduced by 100x

2026.01.04 16:28:02

On January 4, Delphi Digital announced on X that Solana is prepping for a major upgrade dubbed Alpenglow. This is a comprehensive overhaul of the network’s consensus mechanism, aimed at achieving sub-second finality by replacing Tower BFT and Proof of History (PoH). Alpenglow introduces two key protocol components: Votor and Rotor. Votor replaces Tower BFT’s incremental voting rounds with a lightweight vote aggregation model. Validators can aggregate votes off-chain before submitting final confirmations, allowing blocks to finalize in 1–2 confirmation rounds. This cuts theoretical finality latency to 100–150 milliseconds—roughly 100x shorter than the original 12.8 seconds. Votor delivers finality via two parallel paths: - Fast confirmation: Triggers if a proposed block gets over 80% stake-weighted support in the first round, taking immediate effect. - Slow confirmation: Triggers if first-round support is 60–80%, requiring a second-round vote exceeding 60% to finalize. Rotor restructures Solana’s block propagation layer. The original Turbine network uses multi-hop relays with variable delays, while Rotor introduces stake-weighted relay paths to boost bandwidth efficiency. High-stake, bandwidth-reliable validators will act as core relays. Simulation data shows block propagation can complete in as little as 18 milliseconds under typical bandwidth conditions. The upgrade is set to roll out gradually, with an initial launch window targeted for early to mid-2026.

NVIDIA CEO Jensen Huang is discussing plans to return to the company with his allies, while Silicon Valley executives plan to form a "war room" to lobby the firm's board of directors.

According to a report by the Financial Times, Jensen Huang, former CEO of NVIDIA, is discussing the possibility of returning to the company’s management with close associates. Multiple Silicon Valley tech figures are pushing NVIDIA’s board to reappoint Huang, and plan to form a “war room” to secure support from tech industry executives and the White House. Tesla and SpaceX CEO Elon Musk and Epic Games CEO Tim Sweeney have publicly backed a joint letter calling on NVIDIA’s board to “bring Jensen Huang back.” Some NVIDIA employees have also publicly voiced their support for Huang. However, Huang’s return faces resistance. U.S. Treasury Secretary Scott Bessent called on NVIDIA on Sunday to make “significant leadership changes.” Meanwhile, NVIDIA’s board is conducting an independent investigation into the actions that triggered the management crisis, and the company is currently led by interim CEO Colette Kress. Huang stepped down earlier after being exposed for having an extramarital affair with Alice Huang, an executive at Singapore-based chip firm Megaspeed who is suspected of being a spy. The incident also raised external questions about NVIDIA’s compliance review mechanisms when selling AI chips to Asian clients. In addition, NVIDIA’s board previously reached out to Arm CEO Rene Haas to discuss the possibility of his taking over, but the board stated that it has not yet launched a formal selection process. NVIDIA’s two major shareholders, Brad Gerstner, founder of Altimeter Capital, and Gavin Baker, head of Atreides Management, also previously sent a joint letter to the board, calling for Huang’s return to be considered.

The number of signatures on the petition calling for Jensen Huang's return has surpassed the 150,000 mark, with well-known public figures including Elon Musk and Tom Lee having publicly expressed their support.

The petition drive urging NVIDIA’s board to reinstate Jensen Huang continues to gain momentum. To date, the website has collected 151,083 signatures, including 7,380 current NVIDIA employees, 1,381 former employees, and 80,205 shareholders, among others. High-profile figures including Elon Musk, Tom Lee, and Replit CEO Amjad Masad have publicly added their names to the petition. On November 12, 2026, NVIDIA announced that Jensen Huang was stepping down as chief executive officer, effective immediately, marking the end of his 33-year tenure leading the company he co-founded. Campaign organizers and signatories express concern that Huang was forced out without due process or adequate time to defend himself, and are demanding the board provide an explanation. The open letter’s core requests to NVIDIA’s board are: reinstate Huang as CEO pending an independent investigation into the facts; if he remains in a leave of absence, provide evidence-backed justifications. The letter also calls for an independent investigation with clear scope and timeline, a fair opportunity for Huang to defend himself, and timely public disclosures addressing concerns, evidence, and trade-offs for employees and shareholders. The letter stresses: “Thirty-three years of leadership do not mean immunity from accountability, but accountability requires evidence and due process, not a public trial by the crowd.” The website notes that the campaign is independent and has not been endorsed by NVIDIA or Jensen Huang personally.
