It looks like you've got a blockchain-related notification!

Let's break it down:

* **Price:** This is likely the current price of Bitcoin (BTC) in USD, which is $56,877.87.
* **Moscow time:** This could be the timestamp for when the block was mined or verified. Moscow is 3 hours ahead of UTC, so if we assume this is the timestamp, it would be around 18:58 UTC (5:58 PM EST).
* **Block fee:** The block fee is the cost to have a transaction included in the next block. In this case, it's 2.22 satoshis per byte, which is a relatively low fee compared to current market rates.
* **Block Size:** This indicates that the block size is approximately 1.63 megabytes (MB).
