Bitcoin-Safe: The Ultimate Bitcoin Savings Wallet
Bitcoin-Safe, the open-source Bitcoin savings wallet, has officially launched its latest version, 1.5.0, on September 1, 2025. This innovative wallet is designed to cater to families, individuals, and companies looking for secure, long-term Bitcoin storage solutions. Unlike traditional desktop wallets like Electrum and Sparrow, Bitcoin-Safe focuses on multisig security and requires hardware wallets for mainnet operations, ensuring maximum protection for your digital assets.
Development and OpenSats Support
Andreas Griffin, the mastermind behind Bitcoin-Safe, has been working on this project for over two and a half years. His primary goals were to simplify multisig setups and reduce reliance on Electrum servers. With the support of a one-year OpenSats grant awarded in March 2025, Bitcoin-Safe has been able to further enhance its security features and user interface. The wallet is built on the Bitcoin Dev Kit (BDK) and offers auditable open-source code on GitHub. Users can download the installable clients for free from bitcoin-safe.org/download, compatible with Windows, macOS, and Linux operating systems.
Multisig, Hardware Wallet Security, and Coin Control
Bitcoin-Safe prioritizes hardware wallets for mainnet operations, eliminating the use of software seeds to minimize security risks. This approach ensures that users can securely store their savings without compromising on safety. The wallet’s multisig setup wizard simplifies the process of creating multisig wallets by generating PDFs with wallet descriptors and conducting send and receive tests for verification. This guarantees a foolproof configuration, making multisig accessible to all users.
Using the Nostr protocol, Bitcoin-Safe enables encrypted end-to-end synchronization of transaction and address labels across devices. This protocol ensures seamless sharing of Partially Signed Bitcoin Transactions (PSBTs) among multisig participants. Additionally, the wallet categorizes coins to prevent unintended transaction linkages, enhancing user privacy and security.
User Interface and Experience
Version 1.5.0 of Bitcoin-Safe introduces a revamped user interface, developed in collaboration with @deSign-r. The new interface features a sidebar for managing multiple wallets, updated transaction views for sending and signing PSBTs, and a mempool visualization displaying block and fee data. The wallet also includes keyboard shortcuts, tooltips, and clear error messages for improved functionality. Real-time conversion for 123 fiat currencies, integration of Bitcoin to gold or silver values, and mempool alerts enhance the user experience.
Community and Accessibility
Bitcoin-Safe supports multiple languages, including English, Chinese, and Spanish, with translations available via Weblate. Users can engage with the community through Chorus.community and follow Bitcoin-Safe on social media platforms. The wallet also allows users to test with tBTC, report bugs, and donate via Lightning or onchain. Comprehensive documentation is available at bitcoin-safe.org for easy reference.
Future Development: Compact Block Filters
In the pipeline for Bitcoin-Safe is the integration of compact block filters in 2025 to replace Electrum servers. This upgrade aims to fetch blockchain data directly from Bitcoin Core nodes, enhancing privacy and server independence. With continuous development and a strong focus on security, Bitcoin-Safe is set to revolutionize the way users store and manage their Bitcoin savings securely. The Impact of Climate Change on Global Biodiversity
Climate change is one of the most pressing issues facing our planet today, and its effects on global biodiversity are becoming increasingly evident. Biodiversity refers to the variety of plant and animal species that exist in a particular ecosystem, and it plays a crucial role in maintaining the health and stability of our planet’s ecosystems.
One of the most significant impacts of climate change on global biodiversity is the loss of habitat. As temperatures rise and weather patterns become more unpredictable, many species are finding it difficult to survive in their natural habitats. This has led to a decline in populations of many plant and animal species, and in some cases, entire species are facing extinction.
Another major impact of climate change on biodiversity is the disruption of food chains and ecosystems. As temperatures continue to rise, many species are being forced to migrate to new areas in search of suitable habitats and food sources. This can lead to competition for resources and an imbalance in ecosystems, which can have far-reaching consequences for the health of our planet.
Climate change is also causing changes in the timing of natural events, such as the blooming of flowers and the migration of birds. These changes can disrupt the delicate balance of ecosystems and lead to declines in populations of certain species.
In addition to these direct impacts on biodiversity, climate change is also contributing to other environmental stressors, such as deforestation, pollution, and overfishing. These factors can further threaten the survival of many plant and animal species and exacerbate the effects of climate change on global biodiversity.
It is clear that urgent action is needed to address the impacts of climate change on global biodiversity. Governments, organizations, and individuals must work together to reduce greenhouse gas emissions, protect and restore natural habitats, and implement sustainable practices that will help to mitigate the effects of climate change on our planet’s biodiversity.
By taking action now, we can help to protect the incredible diversity of life on Earth and ensure a healthy and sustainable future for generations to come. The time to act is now.
