German AfD secures a decisive victory in Saxony-Anhalt as the debate over Bitcoin tax exemption policies intensifies
According to Cryptopolitan, the far-right German Alternative for Germany (AfD) secured first place in the Saxony-Anhalt state election with a 43.8% vote share, winning 39 out of 83 seats, while the CDU's vote share plummeted to 17.2%. While this victory does not directly affect federal tax law, it will further strengthen the AfD's voice in Berlin's discussions on cryptocurrency tax reform. The AfD has consistently advocated for retaining the 12-month holding period tax exemption for Bitcoin and opposes classifying private mining and Lightning Network node operations as commercial taxable activities. In contrast, the German Federal Ministry of Finance plans to scrap this exemption, aiming to generate at least €1 billion in additional annual revenue.
Boltz indefinitely suspends Bitcoin swap service due to accelerated AI-assisted attacks
Odaily News: Non-custodial Bitcoin swap service Boltz has indefinitely suspended its Bitcoin swap service, stating that the service will remain offline until further notice, with no timeline for restoration provided. Boltz allows users to transfer Bitcoin between the Lightning Network and the Bitcoin base layer, without the company ever holding custody of user funds. Boltz stated that over the past few months, its infrastructure has faced a continuous increase in automated, AI-assisted probing, and the team has already handled multiple exploit incidents. The company said each incident was contained, but the speed at which attackers iterate has outpaced the team's ability to discover and patch vulnerabilities. Boltz disclosed that the pace of attacks has accelerated over the past few days, and after reviewing recent security scan results, the company concluded that it cannot responsibly re-enable the swap service. Its API remains available for processing collaborative refunds, unilateral refunds remain operational as they do not rely on Boltz infrastructure, and customer support remains accessible.
Liquid Attack Leaves L-BTC Redemptions Paused, Attacker Holds Over $51 Million in Bitcoin
Odaily News: Canadian Bitcoin exchange and wallet company Bull Bitcoin stated that due to the Liquid Network attack on September 6, users are temporarily unable to redeem L-BTC back to Bitcoin through the platform, and redemption operations are still pending resumption.Bull Bitcoin expects the related redemption service to potentially resume within 30 days, but stated that this expectation is not guaranteed. Due to its reliance on the L-BTC redemption mechanism to balance inventory, the platform has temporarily closed inbound Lightning Network payments.In this attack, the attacker transferred out nearly 4,000 Bitcoin from the protocol, later returning approximately 3,400; currently still holding 598.50 Bitcoin, valued at over $51 million. Liquid Network stated on September 17 that block production, network transactions, and L-BTC transfers have returned to normal. (Bitcoin.com News)
Due to sanctions, NoOnes will gradually wind down its operations
Odaily News: Peer-to-peer cryptocurrency trading platform NoOnes announced that it will begin gradually winding down operations after running for over three years. The company stated that it had been continuously seeking to resolve and lift the sanctions imposed on NoOnes, but ultimately failed. The sanctions caused the platform to lose key partners, and blockchain monitoring firms also flagged transactions associated with NoOnes as high-risk, making it increasingly difficult for the platform to continue normal operations. According to the plan, the business contraction began on August 17, and the P2P marketplace will close at 23:59 UTC on August 21. Services such as Swap, NoOnes Visa, fiat withdrawals, the gift card store, and the Bitcoin Lightning Network will also be discontinued progressively. After that, the platform will only support withdrawals, and users will still be able to log in, view balances, and withdraw remaining assets. The company advises users to complete asset withdrawals as soon as possible, no later than August 23. Previously, on January 26, 2025, NoOnes revealed that the platform had suffered a major security breach earlier that month, resulting in losses of approximately $8 million in crypto assets. CEO Ray Youssef confirmed the news after on-chain detective ZachXBT disclosed the hacking incident on his Telegram channel.

Bitcoin BIP-110 Nears Block 961,632, Miner Signal Support Rate Only 2.45%
Odaily News: Bitcoin's BIP-110 will enter the enforcement phase after block 961,632, where nodes will reject blocks that do not signal support. Monitoring page data shows that among the 1,674 blocks counted in the current cycle, only 41 blocks support BIP-110, putting the miner signal support rate at 2.45%. BIP-110, officially named "Reduced Data Temporary Softfork," plans to tighten certain data rules in Bitcoin transactions within approximately one year, restricting the size of certain data elements used by Ordinals inscriptions and multiple token protocols. The proposal is primarily distributed through Bitcoin Knots, and Bitcoin Core has not adopted it. Major mining pools such as Foundry, Antpool, F2pool, and Viabtc have not issued support signals. If BIP-110 nodes execute as planned, the network could see two transaction histories, with the majority of miners and Bitcoin Core users expected to continue using the existing rules. Australian Bitcoin exchange Hardblock stated that BIP-110 activation is expected around August 7-8 and may temporarily suspend buying, selling, deposits, and withdrawals. Lightning Network tools and analytics provider Amboss has warned of a fork risk in early August, and Australian Bitcoin exchange Bitaroo plans to freeze deposits and withdrawals as the mandatory signaling deadline approaches.
Polymarket Integrates Spark, Enabling Instant Deposits via Bitcoin Lightning Network
Polymarket has integrated Spark, a Bitcoin Layer 2 payment protocol, allowing users to make instant deposits via the Bitcoin Lightning Network.According to the report, Spark will provide underlying payment infrastructure for Polymarket, enabling users to deposit directly with BTC, with funds arriving in seconds. Compared to traditional on-chain Bitcoin transfers, which take 30 minutes to 1 hour for confirmation, this offers faster speed, lower costs, and greater privacy. This integration is also part of Polymarket's ongoing efforts to enhance the Bitcoin payment experience, following its earlier move to support Bitcoin deposits. (Digital Assets)

BTCPay Server Hit by Critical Vulnerability Exploit, Supporters Launch Up to 3 BTC Bounty to Recover Stolen Funds
According to The Block, open-source Bitcoin payment processor BTCPay Server disclosed a critical security vulnerability being actively exploited last Friday and urgently requested users to upgrade to version 2.4.2. The vulnerability affects all versions prior to 2.4.2; attackers can use it to steal administrator macaroon authentication credentials of LND nodes, thereby fully controlling the connected Lightning Network wallets. Users such as Foundation and Citadel21 have confirmed that their Lightning node funds were drained, but BTCPay has not publicly disclosed the total amount stolen or the number of affected nodes. Currently, the official release version 2.4.2 has fixed this vulnerability, and on-chain hot wallets are not affected. The BTCPay Server Foundation has donated 0.21 BTC each to security researcher Craig Raw and Bitcoin Red Team to commend their responsible private disclosure of the vulnerability. Meanwhile, BTCPay supporters have promised to provide a bounty incentive of "10% of recovered funds," capped at 3 BTC.
The Tether-backed UTExo initiative will launch USDT on the Bitcoin network this month, supporting private transfers and direct BTC exchanges.
According to CoinDesk, Utexo, an infrastructure project supported by Tether, plans to issue USDT on the Bitcoin network this month. Utexo has obtained a commercial license to issue USDT on Bitcoin and plans to provide corresponding APIs, SDKs, and cloud infrastructure for exchanges, wallets, and payment service providers. Based on the RGB protocol and the Bitcoin UTXO model, Utexo will keep most transaction data off-chain, with a focus on supporting three types of applications: private USDT transfers, direct swaps between native BTC and USDT, and borrowing using native BTC as collateral without wrapping BTC to other blockchains. USDT was first issued on the Bitcoin network via the Omni protocol in 2014, after which Ethereum and Tron gradually became its primary circulating networks. Following the issuance of USDT on the Bitcoin mainnet, Utexo also plans to further expand to the Lightning Network.
