Das PV-Unternehmen #GridParity ist insolvent und kritisiert die #Bundesregierung scharf.

Grund sei der angekündigte Stopp der Förderung kleiner #Solaranlagen, der laut #CEO Erich #Merkle das #Geschäftsmodell untergrub. Seinen Angaben nach seien durch politische Verunsicherung Finanzierungen geplatzt.

Besonders betroffen seien städtische #UrbanPV-Projekte wie überdachte #Schulhöfe oder #Wochenmärkte.

Dentsu confirms a data breach at its U.S. subsidiary Merkle, exposing employee and client data.

The attack prompted system shutdowns and an ongoing investigation, with no ransomware claim as of now.

Merkle’s client roster includes Microsoft, Nestlé, Hilton, and 7-Eleven - underscoring how supply chain risk extends deep into data-driven marketing.

How should agencies handling global consumer data improve their cyber resilience?

🌕 Rust 實作的 Merkle 樹:兼具彈性儲存與雜湊功能,效能卓越
➤ 深入解析 rs-merkle-tree 專案:Rust 打造高效 Merkle 樹的技術細節
https://github.com/bilinearlabs/rs-merkle-tree
這是一個以 Rust 程式語言開發的 Merkle 樹實作專案,強調其高度的可配置性,允許使用者自訂儲存後端(如 sled、rocksdb、sqlite 或記憶體)與雜湊演算法(如 Keccak256、Poseidon 等)。此專案僅支援固定深度和增量式新增節點,特別針對快速產生 Merkle 證明進行了效能優化。專案提供了清晰的使用範例,並包含效能基準測試數據,展示了不同配置下的讀寫吞吐量與證明生成時間。
+ 這個 Rust 實作的 Merkle 樹看起來很有潛力,尤其是它支援多種儲存後端和雜湊函數的靈活性,這在需要客製化應用的場景下非常有用。我特別感興趣的是它的證明生成速度,聽起來比我目前使用的方案要快很多。
+ 看了底下的基準測試數據,在記憶體儲存下的證明生成速度
