---Reports---
-International Events-
1. Saudi Arabia signs a mutual defense pact with nuclear-armed Pakistan after Israel’s attack on Qatar: While not specifically discussing nuclear weapons, the agreement states “any aggression against either country shall be considered an aggression against both,” according to statements issued by both Pakistan’s Foreign Affairs Ministry. “Pakistan has nuclear weapons and delivery systems that can hit targets across the Middle East, including Israel. It also is developing systems that can reach targets in the U.S.. (AP)

2. With Eye On US Threat, Venezuela Holds Caribbean Military Exercises: Venezuela said Wednesday it had begun three days of military exercises on its Caribbean island of La Orchila as tensions soar amid US military activity in the region. "There will be air defense deployments with armed drones, surveillance drones, submarine drones... We are going to implement electronic warfare actions," he added, citing the "threatening, vulgar voice" of the United States, said the Defense Minister. (IBTimes)

-US Events-
1. Trump designates anti-fascist Antifa movement as a terrorist organization: Trump characterized Antifa as a harmful and extreme left-wing threat and announced he intends to push for comprehensive investigations into those financially supporting the group, adhering to the strictest legal standards. (GroundNews)

2. Rural Pennsylvania community shaken after shooting leaves 3 officers killed, 2 wounded: When officers in rural Pennsylvania approached a farmhouse to serve a warrant Wednesday afternoon, they had no idea of the danger they would face as an armed man dressed in camouflage lurked in nearby cornfields. The shooter began opening fire, striking and killing three officers. (CNN)

3. DHS, ICE Secures 1,000 Partnerships with State, Local Law Enforcement: The 287(g) program gives states and local law enforcement agencies the tools and authority to arrest murderers, gang members, rapists, pedophiles, and terrorists from American communities. ICE will fully reimburse agencies for the annual salary and benefits of each eligible trained 287(g) officer, including overtime coverage up to 25 percent of the officer’s annual salary. Law enforcement agencies will be eligible for quarterly monetary performance awards based on the successful location of illegal aliens provided by ICE. (Breitbart) (AC-This is kind of a 'federalization' of local police officers-dangerous ground.)

-Regulatory and Legal-
NSTR

-CBDCs/World Currencies/Strategic Reserves-
1. MoneyGram Introduces Stablecoin-Backed App in Colombia: MoneyGram has launched a new mobile app in Colombia using USD-pegged stablecoins on the Stellar blockchain to modernize cross-border remittances. The app allows instant money transfers into a US dollar balance backed by Circle’s USDC stablecoin, addressing the volatility of local currencies like the Colombian peso. (Decrypt)

[abdel @AbdelStark]

Yosh, this is markstr, a POC for Nostr-based oracle resolution for prediction markets on Bitcoin, showcased on Mutinynet signet with CTV and CSFS activated.

The outcome resolution script looks like this:
<outcome_message_hash> <oracle_pubkey> OP_CHECKSIGFROMSTACK

The oracle needs to sign a particular Nostr event (with a content like: PredictionMarketId:SJ1IPWRX Outcome:Yes - Bitcoin above $100k Timestamp:175284641) and the outcome resolution is then verified onchain using CSFS opcode.

The witness for the taproot script path will then be: signature (of the outcome hash / Nostr event id), script (resolution script shown above), control_block.
