Mi trabajo actual en Bitcoin me hace agradecer todos los días la carrera de Ingeniería de sistemas. Programar transacciones Taproot no es para cualquiera.

ord io was one of the main explorers and discovery layers of ordinals ecosystem
its shutdown doesn’t affect Ordinals (protocol) directly but it does impact part of the infrastructure and culture around ordinals and runes
Ord io is shutting down on June 1.
Three years ago, we launched our idea for "an Ordinals explorer with upvotes". We had no idea what was about to happen.
Since then, Ord io has grown into a platform used by over a million people to explore inscriptions on Bitcoin.
It brought us so much joy to ship features like Satributes for discovering the rare sats behind inscriptions and Block Vision for monitoring real-time Runes minting activity.
Even simple filters and sorting options took on a life of their own. "Sort by largest inscription" quickly turned into a leaderboard where inscribers competed to create the biggest "four megger".
And even the things that annoyed us at the time are funny to look back on now, like when the Bitcoin Puppets community would "raid" other collections so hard that we had to remove the downvote feature.
To help preserve some of the Bitcoin culture that happened on Ord io, we'll be uploading the full history of upvotes, replies, and public address profiles to GitHub. That way, if someone wants to build their own Ordinals explorer with this context in the future, they can.
Thank you to every single artist, collector, dev, and degen who joined us for this ride 🧡

Argentine politician, an ALS patient, couldn’t access his Binance account because facial recognition failed due to physical changes caused by his condition. he reports 5 months without access
identity-based access assumes user won’t change over time

ESTEBAN BULLRICH: “LA ELA SE ESTÁ LLEVANDO MI CUERPO, NO DEBERÍA LLEVARSE TAMBIÉN MI DINERO”
El exministro cuestionó a la plataforma Binance por no poder acceder a su cuenta porque el sistema de reconocimiento facial dejó de identificarlo. Según explicó, los cambios en su rostro por la ELA impiden validar su identidad.
Señaló que lleva cinco meses sin respuesta y denunció la falta de alternativas accesibles para personas con discapacidad. Tras la repercusión, la plataforma se contactó con Bullrich y aseguró que trabaja en resolver el problema. También indicó que el caso será tratado como una falla de accesibilidad que es necesario corregir.
Testimonio de Esteban Bullrich
"La ELA se está llevando mi cuerpo. No debería llevarse también mi dinero".
"Nada. Ninguna alternativa accesible para usuarios con discapacidades".
"Esto es lo que pasa cuando una plataforma que mueve miles de millones trata la accesibilidad como algo opcional".

institutions are adopting Bitcoin
Apr 25
Bitcoin active addresses have dropped back to levels seen in the 2018 bear market, though the exchange rate is far higher.
I think we're seeing the result of institutions siphoning off significant demand for block space.
Bitcoin is "scaling" economically... via centralization.

many controversies in Bitcoin start with proposals to change default values in the code
today, Bitcoin has 175 configuration options, each with a default. if you don’t explicitly set them, your node runs with those defaults
that is why they matter
most users don’t tweak every setting. they run a node and rely on what is defined. so in practice, defaults shape how Bitcoin behaves across the network
by changing the defaults, you are voting and changing Bitcoin

bip85 is interesting because it’s a standard that allows you to store a single master seed and deterministically derive multiple independent secrets from it, such as other private keys
this means you store just one thing but can generate virtually unlimited keys
it simplifies backups and each derived seed behaves like a completely separate wallet (if one is compromised, the others remain private)
within the standard, there is a the derivation path where 83696968' is used to specify that this is a bip85 derivation, and then additional values indicate whether you are deriving a seed, hex data, an extended private key (xprv), the language of the seed, and the number of words used (12, 18, or 24)

The Recovery Key is not a password.
It is a 12-word BIP-39 seed phrase generated on your device.
It encrypts your app backup. It derives your hot keys via BIP-85. It restores your entire vault.
One phrase. No account. No server.

If Argentina had never chopped zeros off its currency, one US dollar today would cost 14 quadrillion pesos.
$14,000,000,000,000,000 per dollar.
Most people think this is an Argentina problem.
It isn't.
Writing about it tomorrow.

what advantages does the new privatebroadcast argument provide?
running a node over Tor improves network privacy by hiding your IP address but without private broadcast, transactions are sent to peers over the same Tor connection. this means a peer can observe that tx1, tx2, tx3 all come from the same connection, which reduces privacy.
with this argument, a unique short-lived Tor connection is created with the peer before sending the transaction. this reduces the ability to infer the origin of a transaction and improves privacy

did they hack the hacker? how is that possible?
ARBITRUM RECOVERS $70.9M FROM KELPDAO EXPLOITER
The Arbitrum Security Council just removed $70.97M ETH from the KelpDAO Exploiter’s addresses. They sent it to the address 0x0000000000000000000000000000000000000DA0
North Korea stole the money and Arbitrum stole it back.

the asmap flag is a Core parameter used to determine the diversity of the peers your node connects to. it helps prevent your node from connecting to many peers controlled by the same entity
more diversity means less centralization when receiving information from other nodes
logic: github.com/bitcoin/bitcoin/b…
-asmap=0, Core falls back to the default behavior of grouping peers by IP prefixes
-asmap=1, Core uses an embedded binary ip_asn.dat to group peers based on ASN (better logic)
there is also an option to load your own custom asmap file

Running Core v31.0 with asmap=1.

cluster mempool info
Mar 29
one of the changes expected to be included in Core 31 is Cluster Mempool
transactions in the mempool are nodes with fee, weight, and dependencies. this creates a DAG (directed acyclic graph) structure where transactions are interdependent. any valid block must respect these relationships and include ancestors when selecting a transaction
this leads to the Maximum Ratio Closure problem: selecting a closed subset that maximizes fee relative to weight, and turns block construction into a graph optimization problem
previously, the mempool was treated as a flat set of independent transactions and now the Cluster Mempool groups connected transactions and evaluates them as graphs
this impacts CPFP, fee estimation, and RBF algorithms (become more complex due to graph interactions)

Bitcoin doesn’t care who you are, what you have, or where you were born
the network is neutral and will propagate a valid transaction regardless of its origin. anyone can create a transaction, broadcast it, and trust that it will be written to the blockchain

the testing guide for Bitcoin Core 31 is ready. for those who want to learn Bitcoin from a technical perspective, i recommend running these tests. they walk you through:
- how to compile Core
- how to run commands from the console to interact with your node
- how directories are structured and which environment variables you need
you’ll also help the ecosystem find bugs while you learn

Bitcoin addresses are resistant to human errors (like changing or deleting a character) because they include a checksum. the checksum is additional data embedded in the address that allows it to be validated, ensuring all characters are correct
a Bitcoin address typically has three components: a prefix that indicates the address type, a hash of your public key, and the checksum. all of this is encoded to produce the final address
