segregated witness – Hardware Wallet Vulnerability Fix – Verifying Input Value

I’m confused by the proposed solution posted in the blog regarding the recent vulnerability https://blog.trezor.io/details-of-firmware-updates-for-trezor-one-version-1-9-1-and-trezor-model-t-version-2-3-1-1eba8f60f2dd?gi=504a17ecca1c

The fix is straightforward — we need to deal with Segwit transactions in the very same manner as we do with non-Segwit transactions. That means we need to require and validate the previous transactions’ UTXO amounts. That is exactly what we are introducing in firmware versions 2.3.1 and 1.9.1.

I thought the value was already required to sign a raw segwit transaction… Since the change to segwit the full value of the input was needed in order to sign the raw transaction whereas before with legacy addresses you can simply sign without the input value amount.

They basically state the same thing in the article:

This is defined in BIP-143 and one of the changes was that the amount
of the UTXO is present in the signed data. This helps significantly;
if the attacker lies about the UTXO’s amount, the signature is simply
not valid in the Bitcoin network.

I guess I need it explained to me like a child because I don’t get it, what are they checking and validating, how are they validating? Are they going back two transactions now?

How to fix Windows explorer file icon for icon file (.ico)?

After setting a program like Paint 3D as a default program to open .ico files, the Windows explorer doesn’t show the icon itself next to the file name anymore. Instead it only displays the icon of the chosen default program. How do you restore it to show the icon itself instead of the icon of the default program?

How to fix iPhone X + iOS 13 Slow Wifi?

How do I fix slow wifi on an iPhone XR (iOS 13.4.1)?

The boss has an iPhone XR (iOS 13.4.1), and I have an iPhone 6 (iOS 12.4.5). The iPhone 6 gets 100% better Mbps throughput around my house. I have validated my router health and validated network setup on both phones. I have done all the reset/forget network cycling recommended by guides like this and this and this.

I measure the same performance percentage difference–iPhone 6 performs roughly 110% better–in all these tested scenarios:

  • 802.11 b/g/n 2.4 GHz network connection on both phones, simultaneously
  • 802.11 ac 5 GHz network connection on both phones, simultaneously (first screenshot)
  • Bluetooth off (second screenshot)

My test was:

  1. hold both phones in hand
  2. test average Mbps download speeds using Wi-Fi Sweetspots app
  3. average over ~10 seconds
  4. test 6 different spots around the house
  5. record results

Here are the side-by-side results of the latter two tests; left side is iPhone XR + iOS 13.4.1, right side is iPhone 6 + iOS 12.4.5

test on 5GHz AC network

Test with bluetooth radio off on both phones:

enter image description here

In both tests, “Spot 4” is standing directly next to the Wifi router.

Update:

Here are the recorded results in a Google Spreadsheet for at least 6 tests. The 5 of the top 6 results were for the iPhone 6 + iOS 12.4.5 combination.

hostgator can’t fix this issue, maybe you can


This isn’t a web hosting problem, but it kind of is, and I don’t know where else to post this.

Hostgator repeatedly starts issues tickets for this, says they’ll get back to me, and says they can’t recreate the issue, which is wacko. I have a screenshot and a video of the issue, which has been going on for weeks.

Here is the concern.

When I load my email, horde, if there are new messages, everything happens as it should.

When I load my email, if there are no new messages, it says there are no messages at all in my inbox and I cannot load any of them. An empty inbox! I freaked out the first time this happened, all my emails were gone!!! When this happens, if I select another folder and then return to inbox, they load as they should, however in the wrong order.

In other words:

New emails –> emails load

No new emails –> inbox is empty

Apparently no one at hostgator can recreate this. I have sent them a screenshot and a video of this happening.
