Silent Payments

Receive private payments from anyone on a single static address without requiring any interaction or extra on-chain overhead.

Update: This now has a BIP and WIP implementation

Overview

The recipient generates a so-called silent payment address and makes it publicly known. The sender then takes a public key from one of their chosen inputs for the payment, and uses it to derive a shared secret that is then used to tweak the silent payment address. The recipient detects the payment by scanning every transaction in the blockchain.

Amazon S3 now supports a new storage class called Intelligent Tiering. This will be a very attractive option for many customers who have datasets that are accessed in unpredictable patterns. You can set this storage class when uploading any new data. However, the below instructions will allow you to set up a lifecycle policy that will change the storage class of data that already exists in your bucket.

To set up a lifecycle policy to change the storage class of the data currently stored in your Amazon S3 bucket, follow the below steps.

1. Visit the S3 console and go to your bucket of interest.

2. Click on the Management tab at the top and select + Add lifecycle rule.

3. Enter a rule name of your choice (e.g., Convert to Intelligent Tiering storage class). Unless you want to filter which data is converted to the new storage class, you can leave the prefix/tag filter field

Extracing Entropy From Mouse Movement Events

Here are my findings of entropy extraction estimates from mouse movement events in the browser. Tables below show the results sorted by the minimum entropy extraction. Timing events, keyboard events, and other potential sources of entropy that can be collected from the user are not considered here.

A [visual representation][1] of slow, medium, and fast mouse movements can help visualize why the entropy estimation increases as the mouse velocity increases. The recorded data was plotted with Gnuplot as follows:
