When Satoshi Nakamoto created Bitcoin, the full node client came with a wallet often referred to as Bitcoin-Qt. Nakamoto’s simplified payment verification (SPV) concept was not available until two years later, after the former Bitcoin Core developer Mike Hearn published BitcoinJ in 2011. However, prior to the first SPV client or optimized lightweight bitcoin wallet, the first phone-to-phone bitcoin transaction occurred more than 11 years ago on December 7, 2010.

Satoshi’s Bitcoin is nearing its 14-year anniversary, which will occur on January 3, 2023, and to date, the Bitcoin network has been functional 99.98777985271% of the time since its inception on January 3, 2009.

Doublec published his post at 5:47 a.m. (ET) and by 1:30 p.m., the bitcointalk.org member Ribuck explained he got Bitcoind running on his Nokia N900.
“This is so cool,” Ribuck responded. “I’ve installed it on my N900 and am up to block 2,000. I wonder what the khash/s will be — my guess is 50 khash/s. Let me know your bitcoin receiving address, and we can make the first p2p (phone-to-phone) transaction.”
