Growing evidence suggests that there will not be a 'one size fits all' solution to Bitcoin scaling but rather many complementary protocols, each addressing different challenges and markets, that ultimately help usher in hyperbitcoinization.

In the latest Layer-2 Roundup, we delve into second-layer protocols, highlight the importance of interoperability, and showcase the projects using these solutions together to tackle the challenges of adoption and the growing pains that come with it—as we saw in May's high-fee environment.

Privacy has always been an important part of the Bitcoin ethos: money requires fungibility, and fungibility requires privacy. At Blockstream, we actively develop privacy-enhancing methods like best wallet practices in Blockstream Green and Confidential Transactions (CT) in Liquid for Bitcoin users.

One of our aims is to bring greater privacy to the Bitcoin ecosystem, with Bulletproofs++ as the first step. Read the latest from Blockstream Research:

We’ve just released Blockstream Talk #26 on Simplicity, a next-gen blockchain programming and specification language that Dr. Adam Back has referred to as potentially Bitcoin’s last soft fork.

Simplicity’s use of combinators and jets would enable popular covenants like OP_CHECKTEMPLATEVERIFY and SIGHASH_ANYPREVOUT with one soft fork. In this podcast, Blockstream Research engineer Christian Lewe explains what Simplicity is, draws parallels with Mininoscript, how it will be first implemented on Liquid, and why it’s something that Bitcoiners need to know about.

An important reminder regarding the rerelease of AQUA wallet.

Full announcement from JAN3: https://community.liquid.net/c/general-discussion/a-new-chapter-for-aqua

JAN3 took over maintenance of AQUA April '22 (https://coindesk.com/business/2022/04/07/ex-blockstream-exec-samson-mow-raises-21m-for-bitcoin-startup-jan3/) and is gearing up to unveil a new version for both iOS and Android.

While the original app (developed by Blockstream) remains functional, and you can access your funds as usual, it will no longer be updated or available on the App Store, transitioning to the new AQUA now being released. As you wait for the rerelease, feel free to continue using the old AQUA or migrate your recovery phrase to Blockstream Green or a Liquid-compatible wallet of your choice.

For further AQUA updates, please follow JAN3 on TG: https://news.1rj.ru/str/JAN3com

Last month marked the sixth anniversary of the activation of Segregated Witness (SegWit), underscoring the importance of open-source software and the value of running your own Bitcoin node. To honor this historic date, we are using this quarter's update to take an in-depth look at a few of our own open-source Bitcoin products and the progress made in their development over the past three months.

Among the highlights are the latest on evolving cypherpunk multi-tool Jade and a new partnership with ZeroSync to broadcast zero-knowledge proof systems over Blockstream Satellite. We also share updates on a range of other Blockstream-led open-source projects under development set to play a key role in the open infrastructure that will underlie a hyperbitcoinized future.

The latest Blockstream Talk podcast, episode #30, featuring the open-source VLS Project is now available.⚡️

Validating Lightning Signer contributor Ken Sedgwick guides us through:

⚖️ The current state of Lightning Network security
🔑 How VLS enhances node security with remote signing
👨‍💻 Implementation in Greenlight

An improvement over the original MuSig protocol, MuSig2 offers greater privacy, and scalability by enabling a group of signers to produce a single signature representing their collective consent for a specific transaction. Each signer's key material is confidential and has veto power, meaning the transaction can only be approved if every signer in the group agrees. MuSig2 can also provide greater resistance against certain attacks, such as key cancellation, as well as rogue key and replay attacks.
