bitcoin

The concept of Bitcoin was first proposed by Satoshi Nakamoto on November 1, 2008, and officially came into existence on January 3, 2009. Bitcoin is a peer-to-peer, decentralized cryptocurrency that does not rely on a central authority for issuance, but rather completes transactions through a proof-of-work consensus mechanism on the blockchain, commonly known as "mining." Bitcoin uses a distributed database of P2P network nodes to confirm, verify, and record currency transactions, with a total issuance of 21 million coins.

first_img Breez SDK launched stablecoin payment functionality, supporting over 30 networks

According to Bitcoin Magazine, Bitcoin software provider Breez announced that applications built on its Breez SDK now support users receiving stablecoin payments from over 30 networks using their Bitcoin balance.Breez stated that after the recipient selects the network and amount of the payer, the SDK generates a deposit address and displays the amount received, while the payer pays from their wallet as usual; Flashnet completes the exchange in the background, and the funds ultimately enter the recipient's non-custodial wallet in the form of Bitcoin, or in the form of USD if the stable balance feature is used.In June of this year, Breez launched the ability to send USDT/USDC, allowing a single Breez-powered balance to transfer stablecoins bi-directionally across almost all networks. This update is the latest in a series of usability upgrades, following the rollout of features such as Passkey login, Cash App instant account opening, and stable balance. Breez also launched a reference application called Glow in August to showcase the capabilities of the SDK.The Breez SDK is a developer toolkit that allows applications to add Bitcoin payments without having to build their own payment infrastructure, covering wallet creation, sending and receiving, and Lightning Network payments. Developers can provide Bitcoin functionality with minimal code, without needing to run nodes or manage liquidity.In July of this year, Breez announced a partnership with Turnkey, allowing developers to add non-custodial Bitcoin support to wallet applications running on their own servers.

Goldman Sachs: Korean retail investors are flowing funds into cryptocurrency, and KOSPI's upward movement relies more on foreign investment

Goldman Sachs Global Investment Research Department's South Korea stock analyst Chris Cha stated in a report on September 23 that KOSPI has the conditions for a short-term tactical breakout, but the continuous flow of liquidity from South Korean retail investors into the cryptocurrency market will make the index's subsequent upward movement more reliant on foreign capital and local institutions reconfiguring. The report noted that concerns about the Federal Reserve's interest rates have been partially digested by the market, and risk appetite has shifted towards proxy AI themes.The report pointed out that South Korean memory chips provide fundamental support, with fourth-quarter DRAM contract prices expected to grow double digits quarter-on-quarter, and the ramp-up of HBM4 capacity will continue to limit the supply of standard server DRAM. Samsung Electronics' large shareholder returns, continuous buying by institutions, and foreign capital turning into net buying may drive KOSPI towards the resistance zone of 7000 to 7200 points.The report also indicated that the capacity of local South Korean retail investors to absorb has weakened. After Bitcoin returned to $85,000, cryptocurrency trading in South Korea has heated up. According to DefiLlama data cited in the report, Upbit's single-day spot trading volume on June 13 was approximately $770 million, which rose to $1.817 billion on September 22, an increase of about 136%. Based on the total trading volume of $3.27 billion on that day across South Korea's five major trading platforms, Upbit alone accounted for over half. Goldman Sachs believes this will make KOSPI more reliant on foreign and institutional buying in the future, and October is a critical window to test whether foreign capital will continue to increase its investment in South Korean semiconductor and AI assets.

This liquidation marks the company's official termination and complete exit from the previously established Bitcoin corporate treasury reserve strategy, and in the future, it will refocus its funds and liquidity on its core semiconductor business.

Ministry of State Security: The so-called anonymity of virtual currency is a false proposition

The Ministry of State Security's WeChat public account published an article titled "Is Virtual Currency Crime Untraceable? Think Again!" stating that virtual currency has become an important tool for criminals engaging in illegal activities. The associated risks include being a "hotbed" for money laundering crimes, a "shelter" for cyber attacks, and an "accomplice" for espionage and theft. The article argues that the so-called "anonymity" of virtual currency is fundamentally a false proposition.The article states that blockchain is open and transparent, on-chain data is immutable, and complete transaction records are preserved, which can provide a basis for full-chain traceability. Address anonymity is merely a temporary separation of wallet addresses from real identities, and fiat currency exchanges leave traces such as device codes and network IPs. The article summarizes this as examining the ledger, checking the chain, and discussing the private key: the entire transaction leaves traces, making it difficult to hide real identities; if the private key is kept by the individual, it cannot be recovered if lost, while if it is entrusted to a platform, there is a risk of platform bankruptcy or disappearance.The article also mentions that in February 2026, the People's Bank of China and several departments reiterated that Bitcoin, Ethereum, Tether, and others should not and cannot be used as circulating currency, and related activities are classified as illegal financial activities, which are strictly prohibited. The article warns to be cautious of high-paying part-time jobs that settle in virtual currency and states that reports can be made through 12339, www.12339.gov.cn, the Ministry of State Security's WeChat public account, or local national security agencies.
