Border Wallets are a new way to quickly and easily memorize Bitcoin seed phrases.
notes
**Problem** memorizing 24 random words is not super reliable. We use physical backups. Not everybody has the ability or the infrastructure to create backups in multiple geo locations. Maybe travel a lot or fleeing from somewhere. Can't really securely bring backup with you. We are much better at memorizing patterns (https://www.borderwallets.com/docs/words-vs-patterns do the test). A way to quickly and easily memorize a bitcoin seed phrase. 1. Download a blank grid. 2. Draw design/pattern 3. Then generate an entropy grid, which has all words randomly mixed (or deterministic grid from seed words) 4. Create border wallet. (map pattern to grid) 5. calculate checksum word.PayJoin
A type of coinjoin where merchant and buyer create a coordinated transaction. Coordination happens with PayToEndPoint [P2EP] concept. PayJoins obfuscates the total amount being payed and breaks the common ownership heuristic. Has a fallback to ordinary tx. Another benefit is that the merchant saves money by consolidating (assuming higher tx fees in the future).

myNotes
P2EP - pay to endpoint (Blockstream) or PayJoin. Input correction (foundational heuristic) - inputs owned by same user. Mix the history of two coins. It confuses analytic algorithms. It makes it so that the actual amount being paid to whom is all confusing. * It's not obvious that it is a coinjoin.BIPs
Might be helpful to quickly go over the topic of BIPs.

Buy and sell bitcoin privately and securely on a Bisq's peer-to-peer network.
notes
Trading takes place right on the blockchain, which help prevent censorship. * a variety of ways to pay fiat, or alt coin for bitcoin (https://bisq.wiki/Payment_methods) There are volunteers that help handle disputes. Bisq2 https://github.com/bisq-network/bisq2 * complete revamp with many new supports, including a good API. * https://cryptogeek.info/en/exchanges/bisq/3[Introduction to Bisc](https://www.youtube.com/watch?v=slhHF1zoLd4) I tried to install the software but was unsuccessful. I first downloaded the binary and the signature file. Then acquired the public key from the [GitHub repo](https://github.com/bisq-network/bisq/blob/master/desktop/package/29CDFD3B.asc). Then verified the signature against the public key. ```bash $ sudo gpg --import 29CDFD3B.asc gpg: key CD5DC1C529CDFD3B: public key "Christoph Atteneder
Private Payments: BIP 351
https://privatepayments.org A stealth address protocol for Bitcoin - makes it possible for two parties to transact using addresses that only they can calculate.

The prolifically productive dream team Gleb Naumenko and Antoine Riard have released a series of research reports examining channel jamming. Read the lightning-dev post for a brief summary or dive into the gitbook and read the whole shebang.

Coinpool
Gleb and Antoine propose Coinpool, a new shared UTXO ownership model. Coinpool requires three new OP codes to be soft forked into bitcoin script, so don’t hold your breath. It is recommended that you first grok Eltoo since coinpool builds upon the eltoo protocol to add new capabilities.
