Individual miners in Bitcoin mining pools must rely on block templates provided by the mining pool operator. Seven major Bitcoin mining pools have joined the Stratum V2 working group to develop an industry-wide open standard protocol used by mining pool operators to communicate with individual miners in their pools. AntPool, Block Inc, F2Pool, Foundry, MARA Foundation, SpiderPool, and DMND all joined the working group to collaborate on the mining pool communication standard, which could reduce the time it takes pools to successfully mine blocks, according to an announcement from Stratum V2. “Bitcoin mining is competitive and fragmented by design.

Iran entered the final night of February 2026 under a near-total internet shutdown. In the wake of a joint strike by the United States and Israel, Tehran almost completely severed the country's connection to the global internet — likely leaving only users on a government whitelist with access to the outside world. Iran’s internet formally remained part of global routing, but user activity fell almost to zero. That points to a managed restriction on citizens’ access to the external network. Source: IODA. But in that digital darkness, one vital financial service continued to operate without interruption: Nobitex, a cryptocurrency exchange linked to Iran’s ruling elite. Read more
