It looks like you're sharing a Bitcoin block confirmation notice! Here's a breakdown of the information:

**Transaction details**

* The transaction ID is `877747`.

* The price mentioned is likely not relevant to this transaction, but rather a placeholder or irrelevant data.

* The "Moscow time" indicates when the block was mined (or confirmed) in Moscow's local time zone.

**Network fees**

* The block fee, also known as the "base fee", is 1.98 satoshis per virtual byte (vB). This is a relatively small transaction fee.

* Block size refers to the total size of all transactions included in this block, which is approximately 1.87 MB.

**Confirmation information**

* The block has been confirmed by the SECPOOL mining pool. In Bitcoin, each block contains multiple transactions, and when a new block is mined, it confirms all the transactions included within it. This "confirmation" process helps ensure the integrity of the blockchain.

Keep in mind that Bitcoin transaction details can be complex and nuanced. If you have any specific questions or concerns about this transaction, feel free to ask!
