In the last 24 hours, two bitcoin (BTC) block subsidies stemming from 2010 were caught by blockchain parsers, after the addresses transferred 100 bitcoin. At the time of the transfers, BTC was swapping hands for roughly $40K per unit.
The first transaction caught by btcparser.com was a 50 BTC coinbase reward that was minted on July 14, 2010, or over 11 years ago. The transaction was transferred to an empty address that now holds 49.99000615 BTC, and was confirmed at block height 723,812. The transfer was parsed by btcparser.com on February 17, 2022, at 10:01 p.m. (UTC).
Metrics from blockchair.com gave the first transaction, a privacy score of 0, which is a “critical” privacy rating. Blockchair.com says the transfer had “four vulnerabilities discovered for the privacy involved in this address.” For instance, “matched addresses” were identified in the BTC transaction.
The next block reward worth 50 BTC was also caught by btcparser.com on February 18, 2022, at 2:00 p.m. (UTC). Privacy on this particular transfer was a bit higher, as it scored a 45 according to Blockchair.com’s privacy meter. “Three vulnerabilities [were] discovered for the privacy involved in this address” including “matched addresses.”
Both BTC block subsidies for 50 bitcoin per reward were both minted within two days of each other. While the first transaction spent on Thursday was minted on July 14, 2010, the transfer on Friday was a block reward minted two days later on July 16, 2010.
There haven’t been that many 2010 BTC block subsidies spent in 2022. There was one 50 BTC block reward from 2010 spent last month on January 22, and the funds transferred at block height 719,822. So far, the two spent on Thursday and on Friday this week were the only two 2010 block rewards transferred this month. The total since the first of the year equates to approximately three block rewards from 2010 spent in 2022.
2022 has not seen the mystery whale from 2010 that has transferred thousands upon thousands of old block rewards minted that year.
In addition to the two block rewards from 2010 spent on February 17 and 18, btcparser.com caught 100 BTC from June 21, 2011, transfer to another wallet after more than a decade at block height 723,909.
