The Bitcoin Core project has released version v26.0, bringing new enhancements, bug fixes, and performance improvements. This update includes experimental support for the v2 transport protocol, improvements in P2P and network aspects, and the removal of the ability to create legacy wallets. Users can find detailed instructions on upgrading in the release notes.However, a vulnerability in Bitcoin Core has been exposed by developer Luke Dashjr. This vulnerability has been exploited by “Inscriptions,” leading to blockchain spam and network congestion. The Bitcoin core developers team plans to address this issue in the upcoming v27 release next year. This decision has faced criticism from users and miners of ordinals and BRC-20, resulting in a drop in ORDI price. Dashjr explains that Bitcoin Core has had a feature to set limits on additional data size in transactions since 2013, but Inscriptions have found a way to circumvent this limit.Despite the vulnerability, Bitcoin Core v26 remains susceptible to attacks, as there are currently over 250,000 unconfirmed transactions on the network. The hope is to resolve these issues before the v27 release. In the meantime, options traders are placing bullish bets, anticipating a surge in Bitcoin to reach $50,000 by January. This optimism is fueled by expectations that the SEC will potentially approve ETFs to include the cryptocurrency directly.
