Simplicity, the much-anticipated smart contracting language that could revolutionize Bitcoin, has just hit a public blockchain:
@npub1nyy…7gan Testnet.
Developers can start building powerful next-gen contracts today with a new IDE. More details. 👇
https://blog.blockstream.com/simplicity-arrives-on-liquid-testnet/
While building Simplicity, we developed a more developer-friendly "front-end" language called Simfony, which resembles the Rust programming language while elegantly mapping down to Simplicity.
Simfony abstracts away some of Simplicity's functional programming details, making it much easier for developers to write programs and contracts.
https://image.nostr.build/0bb9334b707e31b1e48386680d126d80b3c4d4367db8cc76ee76c2376dd62d9c.jpg
Developers can start building today with a new web IDE as a playground for creating Simfony smart contracts. We've provided some example programs to showcase various use cases, some of which are not possible in Bitcoin Script. The IDE also provides tools for managing public keys and generating addresses on the Liquid testnet.
IDE: https://simfony.dev

In the latest Elements release, we add initial support for discounted Confidential Transactions (CT) fees. This new policy reduces fees by nearly 90%, from around 250 sats to 25 sats, achieving close to what it would be on non-CT transactions.
The 23.2.3 release activates the new fee policy for relay on Liquid testnet. This allows Liquid wallets and platforms to begin integration and testing, with a production release expected in the near future.
The new fee policy will make Liquid’s confidentiality even more economical, particularly when stacking bitcoin in high-fee environments, swapping to Lightning, or sending cross-border stablecoin remittances.

Jade 1.0.31 is here, bringing a host of improvements that make it more powerful, secure, and user-friendly.
Whether you're just starting with Bitcoin or you're a seasoned cypherpunk who demands the best in Bitcoin self-custody tools this update is a significant step forward.
https://image.nostr.build/46b0e4489a00fc2dbaf83982a4ce6e7c03b88c77d8c4229fb46740edc2bd0234.jpg
One of the standout features in this release is the automatic validation of change outputs when signing Blockstream Green wallet 'Multisig Shield' PSBTs. This means you can sign transactions with confidence, knowing that Jade is double-checking the details to ensure your Bitcoin is going exactly where it should. This is especially useful when reorganizing your Bitcoin holdings or consolidating UTXOs. Jade will now highlight when a transaction output is verified as being sent back to the spending wallet.
Jade now alerts you if a PSBT or transaction doesn’t require a signature from your device, ensuring you’re always informed and in control during the signing process. This small but significant addition helps prevent unnecessary steps and keeps your workflow smooth.
User experience has also been refined. If you start entering your PIN and need to backtrack, you can now abandon the entry from the first digit—a simple tweak that makes a big difference in usability. And for those who enjoy DIY setups, Jade now supports 180-degree screen rotation, adding flexibility to your hardware configuration.
Developers and tinkerers will appreciate the new command-line interface tool for simple interaction and testing, along with experimental support for esp32s3 devices like the ttgo-tdisplayS3. These additions expand Jade’s versatility, making it even more adaptable to various needs and setups.
Visually, Jade’s Home and Camera/QRScan screens have been redesigned to enhance navigation and readability, making sure your operations are as intuitive and efficient as possible.
Security remains paramount. Jade now locks only when an active serial or BLE connection is lost, not when you’re simply unplugging for charging. This ensures your device remains secure without disrupting your routine. Under the hood, updates to the ESP-IDF base firmware and a switch to the esp_lcd graphics library further enhance performance and stability.
Fixes in this update include improved UI scaling on larger DIY displays, better handling of change outputs in registered descriptor policies, and correct display of confidential @npub1nyy…7gan Taproot addresses during signing. These adjustments ensure Jade continues to offer top-tier security without compromising on functionality.
Jade 1.0.31 continues a commitment to ensuring that your Bitcoin remains secure, your experience remains seamless, and your tools remain at the cutting edge of self-custody technology.

Today, we’re launching the next generation of Bitcoin mining investments: the Blockstream Mining Note 2 (BMN2). It offers investors direct exposure to hashrate generated at our Bitcoin mining facilities through a tradable security token on the @npub1nyy…7gan.
BMN2 builds on the success of BMN1, which recently matured, generating over 1,212 BTC with net returns of up to 102% over its three-year term. BMN2 offers a similar structure but extends the investment period to 48 months.

Green is the most secure way to hodl #Bitcoin on an internet-connected device. Why? By adding a 2FA-protected account layer, stealing funds from a compromised device is virtually impossible.
Version 2.0.8 elevates this non-custodial service even more! ⬇️
https://image.nostr.build/5fc43eb3d6d1bba446debc4a662c95b2867774c1a6fbf4c968bb97582420e8dd.jpg
When a two-factor authentication (2FA) protected account is created, multiple keys are now required to send a transaction.
The first key is on the device, protected by a PIN code and should be backed up on metal as a 12 or 24-word recovery phrase and kept in a secure location. The second key is held on the Blockstream Green servers protected by 2FA. This is the standard 2-of-2 multisig setup.
Green 2FA protected accounts also allow for 2-of-3 multisig setups where another key is kept on a Blockstream Jade in a secure location for use in recovery.
When setting up a 2FA protected account on Green, it is wise to set up multiple methods on separate devices. This ensures that as long as access to one is retained, the bitcoin will be spendable, and lost 2FA methods can be disabled or changed.
To keep users in control, if all 2FA methods fail, the 2FA protection will expire in 51,840 blocks (~1 year) since the protected coins last moved.
This update adds real-time alerts for upcoming 2FA expirations and introduces a smoother coin control flow for better privacy when refreshing 2FA protection.
https://image.nostr.build/84bf4ae1344360f1c3b059c12f2ca5d2330c8234b1fa57dd97a9ed13da10a94b.jpg
System alerts have also been improved, offering clearer notifications during logins and updates on security matters. Additionally, the system architecture has been upgraded to Qt 6.7.2, enhancing the app's performance and stability for a superior user experience.
Green is fully open-source, and in that spirit, there is an open-source recovery tool called garecovery that can recover funds in the event that the 2FA protected account service is permanently terminated.
Find Green on the app store and start exploring 2FA for funds that you take on the road.

When the $BMN launched, it offered investors a bold new way to engage with Bitcoin mining. Three years later, it's proven its value, delivering a weighted average gross cash/cash return of ~61%.
This week, the BMN1 will begin paying out 1,220+ $BTC on @npub1nyy…7gan. More 🧵⬇️
https://image.nostr.build/a97890878439cde220f727955fba6ec1bcaf95a8f5a93afe3222579e520617b4.png
Some background: Instead of traditional investing methods in physical mining infrastructure, the $BMN offered a more liquid, flexible approach through a hashrate-backed security token that provided investors with hashrate generated at Blockstream Mining facilities.
https://image.nostr.build/284c7e759e28f166566b9fc86315783f164debe758f43a525f63b03e9acd6946.jpg
By removing the barriers of entry to enterprise-grade mining with a security token, investors could participate more easily in Bitcoin's proof of work, contributing to its security and censorship resistance.
https://www.youtube.com/watch?v=nJ56KqzbzQI
As a security token, the $BMN comes with investor protections and allows flexible adjustment of exposure with P2P trading and secondary markets like Side Swap, Merj Exchange, and Bitfinex Securities, among qualified BMN holders.
https://image.nostr.build/8c30b56962b5371d5b92fbd15b3a5cca8a20d227274bf73da20decc1e2c3ab7e.jpg
The bitcoin mined by the $BMN has been held in cold storage and will be delivered to the final token holders beginning later this week. This provides returns without needing to manage hardware or deal with the intricacies of mining operations.
The payout from BMN1 will also have a broader impact on the Bitcoin L2 ecosystem. It will push the Liquid Bitcoin $LBTC in circulation (~5108) on par with the total BTC in Lightning, highlighting its growing significance and utility.
https://liquid.network/
BMN1's success has also paved the way for other tokenized Bitcoin mining investments, such as the Blockstream BASIC Note $BSIC, which allows investors to capitalize on undervalued mining assets.
https://blockstream.com/finance/basic/
You can read further updates on the upcoming BMN1 payout via the official Stokr site, and be sure to set a reminder to join us and members of the Liquid Federation for an ecosystem-wide discussion on $BMN and its impact later this week. ⛏️ 🌊
