The post How Bitcoin Could Reuse Signatures Across Compatible UTXOs appeared on BitcoinEthereumNews.com.
This is Part 3 in the technical article series about Bitcoin covenants by Cointelegraph Research. To read the previous article click here. SIGHASH_ANYPREVOUT, as proposed in BIP 118, builds on the earlier SIGHASH_NOINPUT concept mentioned in the 2015 Lightning Network paper by Joseph Poon and Thaddeus Dryja, and later formally proposed by Joseph Poon on the bitcoin-dev mailing list in February 2016. SIGHASH_ANYPREVOUT is not a new opcode but a proposed new value for the SIGHASH flag, designed to be deployed as a soft-fork upgrade to Bitcoin. The SIGHASH flag is appended to a signature and determines which parts of a transaction are signed and will be checked by the CHECKSIG opcode. The selected flag is chosen by the signer, not enforced by the scriptPubKey. Due to the technical details related to upgradability in a softfork, the SIGHASH_ANYPREVOUT proposal only extends to spends fr
The post New Hampshire’s $100 Million Bitcoin-Backed Bond Faces Final Vote appeared on BitcoinEthereumNews.com.
New Hampshire’s plan to issue what backers call the world’s first Bitcoin-backed municipal bond goes before the state’s Executive Council on Wednesday, the last approval the $100 million project needs before it can move forward, The Boston Globe reported today. Governor Kelly Ayotte, who has called the effort “historic,” and the five-member council will hold a public hearing Wednesday morning at the request of James Key-Wallace, executive director of the New Hampshire Business Finance Authority. Key-Wallace asked the council to find the proposal feasible and beneficial to the public and to authorize the quasi-governmental agency to proceed. He has said the model would position the state as “a global leader in responsible crypto finance.” The structure differs from a conventional municipal bond in a key respect: no public money is at stake. Rather than the government repaying

The post Bitcoin Price Survives $61K Dump: $64K Resistance Holds appeared on BitcoinEthereumNews.com.
Carrying on from Sunday’s retracement, the BTC price slid further on Monday and then dumped quickly, almost reaching $61K. However, as soon as it hit this point, also coming down below the bull market trendline, buyers stepped in and the price was bought up even quicker than it came down. What could be next? Flash crash quickly bought up Source: TradingView The 4-hour time frame chart shows us that the $BTC price broke out from the falling wedge, confirmed the breakout, and moved higher. It was at the point that a correction was expected, that a flash crash occurred, taking the price back into the wedge and below the bull market trendline. However, as can be seen, the crash was very short-lived. Buyers stepped in and the price was rapidly bought back up to the 200 SMA from where it rose higher. The small crash left a substantial candle tail behind, and if one looks left at the other ti

The post Kenya’s Markets Regulator Seeks Blockchain Tool to Track Crypto Crime appeared on BitcoinEthereumNews.com.
In brief Kenya’s Capital Markets Authority is seeking to buy a blockchain analytics platform to police the country’s virtual assets market. The tool would monitor Bitcoin, Ethereum, and at least 20 other networks to flag fraud, money laundering, terrorism financing, and sanctions evasion. The move follows the Virtual Assets Service Providers Act of 2025, which brought Kenya’s crypto sector under formal regulation for the first time. Kenya’s securities regulator wants to buy a blockchain surveillance system to help police the country’s fast-growing crypto market, as it prepares to license and supervise virtual asset firms under a new law.

The post Polymarket Lawsuit Bitcoin Market Dispute Explained appeared on BitcoinEthereumNews.com.
A prediction market dispute that started with a single SEC filing has turned into a full-blown legal battle. Two traders have filed a Polymarket lawsuit over Bitcoin tied to Strategy’s sales, alleging the platform improperly resolved a market — and in doing so, broke its own foundational promise of rules-based outcomes. Key takeaways Plaintiffs William Wood and Thomas Bush sued Polymarket in the New York Supreme Court on July 3, naming CEO Shayne Coplan and CMO Matthew Modabber as defendants. Strategy disclosed in an SEC Form 8-K filed June 1 that it sold 32 BTC between May 26 and May 31, within the contract’s event window. Polymarket resolved the market as “No” after a UMA vote on June 3, despite the SEC filing confirming sales within the deadline period. Plaintiffs allege Polymarket introduced a post-trading confirmation requirement that wasn’t part of the original market rules. Neither
