The Great Script Restoration aims to restore old #Bitcoin opcodes with Taproot analogs.
Could this allow us to solve problems like L1 custody? @Rijndael thinks so.
What do you want to see improved in Bitcoin? Could The Great Script Restoration offer a solution? [BR069]
There are a lot of strong opinions out there about OP_CAT. But what does it actually DO?!
@Rijndael takes it back to basics, discussing with @DETERMINISTIC OPTIMISM 🌞 what CAT does, and crucially, how previously unresolved risks are mitigated against. [BR069]
Ordinals & inscriptions have prompted us to ask questions about how the economics of non-financial transactions could evolve.
Could it disrupt the financial use case of #Bitcoin? And should we/can we mitigate it?
Adam Gibson, Poelstra and @DETERMINISTIC OPTIMISM 🌞 debated this very topic in BR029.
Why does witness data get a discount while UTXO data doesn't?
The answer lies in how and why SegWit resolved the quadratic hashing issue.
Andrew Poelstra discusses with @DETERMINISTIC OPTIMISM 🌞 the reason for the witness discount in BR029.
How do we prevent small UTXOs from being useless due to miner fees outweighing the UTXO?
@DETERMINISTIC OPTIMISM 🌞 , @Alex B. and @craigraw weigh in on this important question, discussing best practices for UTXO management in BR071.
Speedy Trial? UASF? What would be the best approach to activate OP_CAT?
@DETERMINISTIC OPTIMISM 🌞 , @Rijndael and Andrew Poelstra discuss the most practical and safe method of potential CAT activation in the future [BR069].
The incompatibility between LNURL and BOLT12 is causing some friction in the Lightning Network space.
@Alex B. , @Carman and @DETERMINISTIC OPTIMISM 🌞 discuss how can this be resolved and where we're headed with these two standards.
BIP47 and silent payments offer different approaches for payment privacy.
@DETERMINISTIC OPTIMISM 🌞 , @Alex B. and @craigraw discuss the need to consider the UX and long-term viability of these solutions in BR071.
Lava Wallet is set to provide liquidity for #Bitcoin loans, all while keeping it self-custodial and private.
@Alex B. discusses with @DETERMINISTIC OPTIMISM 🌞 how Lava is changing the game when it comes to DLC based loans in BR071.
Want to get started building in #Bitcoin and #nostr ?
Great places to start:
- Programming Bitcoin by @jimmysong
- Bitscript.app learning resources
Or just pick an area that fascinates you, dig into the specs, and start coding! @DETERMINISTIC OPTIMISM 🌞 @craigraw and @Alex B. share their tips.
#bitcoin custody considerations differ for each person.
Without custodians, good key management is paramount. With custodians, rug pulls and social engineering become threats.
@DETERMINISTIC OPTIMISM 🌞 , @Alex B. & @craigraw discuss the varying security considerations, especially as value grows.
Could FROST and ROAST solve #nostr key rotation issues?
@DETERMINISTIC OPTIMISM 🌞 , @Carman and @craigraw explore how these primitives could ensure seamless key management in BR071.
Is this the key (pun intended) to better security? 🔐
Did you hear about the recently launched @Lendasat ?
Lendasat lets you take instant loans to pay Lightning invoices, so you don't need to sell your #bitcoin.
It's a non-custodial protocol powered by DLCs on Ark.
@DETERMINISTIC OPTIMISM 🌞 discussed the project with @Alex B. in BR071.
Security misconceptions are very common in #bitcoin.
@NVK 🌞⚡️ points out a couple of prominent ones, stressing the importance of due diligence.
Don't get caught out by marketing claims!
