Solana

On December 16, 2025, Solana announced a partnership with Project Eleven to develop and test quantum-resistant digital signatures on a Solana testnet. The initiative includes a full quantum-readiness assessment of wallets, validators, and transaction flows. Solana's founder Anatoly Yakovenko has previously cited a 50% probability of quantum attacks against Bitcoin in the coming years, while current threats remain theoretical.

According to data from Pipe, Solana's network absorbed a distributed denial-of-service attack peaking around 6 terabits per second this week without downtime or notable fee spikes, a performance later confirmed by co-founders Anatoly Yakovenko and Raj Gokal. The event coincides with a more than 35% drop in active validators in 2025 and growing concentration of stake among large infrastructure providers, even as Solana processes roughly $1.6 trillion in annual trading volume and supports about $15 billion in stablecoins.

PIPPIN jumped to a fresh all‑time high on December 16 following a sharp squeeze in derivatives. Shorts dominated open interest, while on‑chain whales executed coordinated spot orders on Raydium and PumpSwap. The team made no new announcements during the move.

Invesco and Galaxy Digital launched the staked Solana ETP QSOL on Monday, listing it on the Cboe BZX U.S. equities exchange with 17,500 SOL in custody valued at $2.19 million and a 0.25% total expense ratio. Crypto ETF flows diverged the same day, with Bitcoin spot ETFs seeing $357.69 million in outflows and Ethereum $224.78 million, while Solana products recorded $35.2 million in net inflows.

Singapore-based StraitsX plans to extend its XSGD and XUSD stablecoins to Solana by early 2026. The move targets automated payments and onchain SGD–USD exchange, with the pair having processed over $18 billion in onchain transactions. StraitsX operates under MAS oversight and is exploring a consumer pilot with Grab.

On 16 December 2025, CoinGecko data indicated that Solana attracted more ecosystem-related interest than any other major blockchain, measured by verified organic website traffic. The analysis, covering early 2024 through mid-December 2025, showed Solana captured over a quarter of all attention, leaving Base, Ethereum, Sui, BNB Chain, Bitcoin, and Cardano trailing behind.

Solana faced a sustained DDoS campaign over the past week, with peak traffic reaching 6 Tbps. Despite the pressure, Solana's block production and consensus remained stable. SUI encountered a smaller attack in the past day, which briefly degraded performance before being resolved.

Bhutan and Cumberland DRW signed a multi-year MOU to develop a crypto ecosystem in Gelephu Mindfulness City. The plan emphasizes talent building, national stablecoin infrastructure, sustainable mining, and AI compute. Bhutan also launched the gold-backed TER token on Solana, issued via GMC, with DK Bank as custodian and distributor.

Solana has been subjected to a distributed denial-of-service attack peaking at nearly 6 terabits per second, reportedly the fourth-largest incident ever recorded against a distributed system, yet its network continued processing transactions without disruption. While validators absorbed the week-long surge in traffic, on-chain indicators now point to shrinking liquidity and persistent realized losses, with analysts describing the current phase as a full liquidity reset that could precede the next market cycle.

On December 15, 2025, the U.S. Senate Banking Committee confirmed it would postpone markup of crypto market structure legislation to early 2026. Bitcoin fell over 4% in the past 24 hours, briefly touching $84,000 and stabilizing near $85,800, while total crypto market capitalization slipped to $2.93 trillion.
