Bitcoin transaction

Because the blockchain is public and transparent, anyone can view it. But because you can enter the network pseudonymously and enter your own private key anonymously, you still have financial privacy. Partly for this reason, we do not automatically know who is behind this large transaction.

So we can get more about this transaction out of the blockchain. The payment entered the blockchain yesterday at 15:58 in block 654.364. And then the most important thing of this transaction: the amount.

A total of 88857.24519026 BTC has been sent and divided into two new UTXO’s of about the same amount. The payment was split into ~43,185 BTC and ~45,671 BTC.

If you convert that with the current spot price we can conclude that for $1,155,141,000 the owner has changed hands.

Let that sink in for a moment: more than $1 billion in assets were sent with a decentralized protocol that no bank or payment processor could do anything about.

The payment totalled only 405 bytes. As a result, it only cost 0,00027847 BTC. With the current market price, that comes down to $3.65. The transaction costs are therefore less than 0.0000004% of the total amount.
