The Polygon Foundation announced on X that it has resolved the recent outage affecting its Remote Procedure Call (RPC) services, with all user-facing functions now operating normally. The disruption, which earlier paused block production for roughly an hour, was caused by a validator exit that interfered with the network’s Heimdall layer. The foundation said it has applied a permanent fix to address the underlying issue and prevent a repeat, and added that a detailed post-mortem report will be released soon.

In a recent interview with CNBC, Anthony Pompliano, founder and CEO of ProCapBTC, said Bitcoin has transitioned from a niche investment to a widely embraced asset, calling it “the king of Wall Street.” According to Wu Blockchain, which shared the remarks on X, Pompliano pointed to a roughly 30% decline in the U.S. dollar’s purchasing power over the past five years and noted that the S&P 500 has dropped more than 85% when measured in Bitcoin since 2020.

Dubai-based crypto mining equipment distributor Phoenix Group formalized its $150 million digital asset treasury strategy and added 179 Bitcoin in the second quarter, bringing its total holdings to 514 BTC along with more than 630,000 SOL, according to a Business Wire press release.

NFT sales climbed to $574 million in July, the second-highest monthly total in 2025 after January’s $678.9 million, Cointelegraph reported, citing data from CryptoSlam. The figure marks a 47.6% increase from last month's $388.9 million. Despite the surge in volume, transaction count slipped 9% month-over-month to five million, down from 5.5 million. The average sale price, however, rose to $113.08, the highest in six months. According to NFT Price Floor, the total NFT market cap has surpassed $8 billion, driven in part by rising valuations of Ethereum-based collections, which account for all of the top 10 by market cap over the past 30 days.

Rahul Agarwal, a software engineer at Indian crypto exchange CoinDCX, has been arrested for allegedly aiding hackers in a $44 million breach, according to BeInCrypto. Authorities suspect his credentials were used to access internal systems and siphon funds into six wallets. Agarwal denies the allegations, while the case raises broader concerns over social engineering and credential security.

Five Bitcoin (BTC) wallets that had been inactive for 15 years have transferred a total of 250 BTC ($29.64 million) to two separate addresses, according to on-chain analyst Onchain Lens on X.

Layer-1 blockchain foundation Kaia announced via X that it will terminate the FNSA→KAIA token swap service and officially shut down operations of the legacy Finschia chain starting Sept. 30. After that date, all swap functions will be disabled and the Finschia chain infrastructure will be decommissioned. No further compensation or technical support will be provided for unclaimed FNSA tokens.

South Korean crypto figure "Jonbur Kim," whose real surname is Park and whose nickname roughly translates to "HODL Kim," was denied bail on July 30, according to Herald Business. Park will remain in custody as he stands trial. He was previously indicted for allegedly launching a scam token called PODO, pumping its price and cashing out entirely—netting 80.9 billion won ($58.2 million). After being released on bail, he was hit with a second indictment and taken into custody for allegedly issuing another fraudulent token, Artube (ATT), through which he is accused of defrauding investors out of 260 billion won ($187 million).

South Korean brokerage Kiwoom Securities has applied for several stablecoin-related trademarks, Digital Asset reported. Data from the Korean Intellectual Property Rights Information Service (KIPRIS) shows the firm filed applications for names such as "KiwoonKRW" and "KRWKW." Kiwoom is the third major securities firm in the country to move in this direction, following NH Investment & Securities and Shinhan Securities.

A recent study by Mysten Labs, the developer behind the Sui blockchain, suggests that blockchains using the Edwards-curve Digital Signature Algorithm (EdDSA) are better positioned to handle future quantum threats, according to Decrypt. Unlike these newer networks, like Sui, Solana and Near, older blockchains like Bitcoin and Ethereum rely on the Elliptic Curve Digital Signature Algorithm (ECDSA), which faces steeper technical and operational hurdles in transitioning to quantum-resistant security. The concern stems from Shor’s Algorithm, a classical method that can run on quantum computers to efficiently factor large integers—potentially allowing attackers to derive private keys from publicly available blockchain data. Mysten Labs co-founder and Chief Cryptographer Kostas Chalkias noted that governments worldwide plan to phase out classical algorithms like ECDSA and Rivest–Shamir–Adleman (RSA) by 2030 or 2035. He warned that networks handling sovereign assets, national treasuries, exchange-traded funds (ETFs) or central bank digital currencies (CBDCs) will soon be expected to implement post-quantum cryptographic standards to maintain long-term trust and wide adoption.
