The most notable changes:

• bitcoind used to listen on 127.0.0.1:8334 by default. If you use Tor for incoming connections, you have to manually specify bind=127.0.0.1:8334=onion in config
• unix sockets can now be used to communicate with Tor or other proxy, and MQ traffic.
• New mempool policies has been implemented to patch some attack vectors for chains of unconfirmed transactions, especially in relation to lightning network channels and similar contracts.
• TRUC (Topologically Restricted Until Confirmation, BIP 431) can now be used with transaction version 3 (now considered standard) instead of RBF.
• Full RBF (Replace By Fee) is now enabled by default
• RHEL 8 and Ubuntu 18.04 are now unsupported due to minimum required glibc version bump.

> Researchers predict that by the year 2050, about half of the world's population will have myopia.

Considering the target demographic, a significant number of potential VR users suffer from myopia already. Why are there no more VR headsets with adjustable focus?

Several vendors offer replaceable lenses, or various addons to fit the glasses in, but the obvious solution used by the early cheap headsets like GearVR - adjustable distance between lenses and the display, is not being utilized for some reason.

Is it a technical problem, economical problem? Are the modern lenses somehow tuned for a specific distance?

zkSNACKs, the developer of Wasabi wallet, has shut down its coinjoin coordinator since June. The news is not surprising, considering that it has already been unavailable for the US customers since May.

Since the wallet itself is non-custodial (you hold the keys), and it's using block filters to update your balance directly from the bitcoin network, the wallet functionality is intact. However, if you want to coinjoin, you have to find another public coordinator.

A list of currently active coordinators is available on wabisator.com, or wasabist.io

Coordinators do not require any privileged access to private information, so it should be safe to use any 3rd party coordinator with enough real active users. At no point are your funds at risk of being stolen.

However, a dedicated attacker running a public coordinator could still pull a de-anonymization attack by mixing your coins solely with their own outputs.

Ever since the interview with Lukas Seyfrid (CZ), the chief of the hardware team, it was clear that Braiins is pivoting from the development of mining software, to building their own hardware.

!

This, I believe, is the first iteration of their effort in form of a consumer product, and while it is unlikely to make you a financial return on the investment, it's small form factor and nice anodized aluminum case can allow pretty much anyone to become familiar with the process of bitcoin mining. Or terrorize the testnet. The choice is yours.

I think I might buy one, just to try the viability of a pure solar setup.

HW specifications:

||| | ------------- | ------------- | | Price (pre-order) | $199.00 | | Hashrate | ~1Th/s | | Power Consumption | 40W - 55W | | Number of hashboards | 1 | | Number of ASIC chips | 4 | | Cooling Type | Active | | Noise | 40 dB | | Air outlet temperature | 40-50 °C |

But really, how much would it make in a year?

If we assume the current price and difficulty stays the same, the block subsidy is 3.125 BTC, median fees around 0.2212 BTC, free electricity, you'd get 0.001 BTC per 12 months, which is roughly 65 USD. A little more than 3 years to break even.

It's not going to break any records, but I'm still excited for what's to come next.

It's a successor to the model T, with the new design inspired by the Safe 3, announced earlier this year.

They promise nice, easy to use UI, color display, haptic feedback, gorilla glass. Several color variations are available, including the bitcoin-only orange option.

"Prosecutors are alleging Samourai Wallet laundered over $100 million in criminal proceeds."

"Recent regulatory action against Consensys and Samourai has instilled fear among other crypto service providers operating in the United States."

• Wasabi is the main competitor to Samourai's whirpool mixing service. The only one flying under the radar currently is Joinmarket.
• Phoenix is the Lightning network wallet where users keep custody of their funds, but the channel management is outsourced to the company. The only remaining self custodial lightning wallet that remains is Breez.

While this news is deeply troubling, it might push further development to more sustainable trustless self-custodial solutions in the long term.

The Solomon's temple in Jerusalem was a mistake... according to samaritan israelites, who follows 5 books of the old testament, and pray on Mt. Gerizim, 48km north of Jerusalem. THE place to worship God.

Most of the european christians probably know the term only from the story about the good samaritan. Today I've learned not only they are still a thing, practicing their barebones version of judaism, but in addition to israel and the west bank, some of them even live and practice their religion in brazil.
