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.
Client came with a wallet often referred to as Bitcoin-Qt.

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. During the first few years of Bitcoin’s life, the ecosystem had very little infrastructure compared to today’s plethora of crypto exchanges and bitcoin wallets. The protocol’s second Bitcoin client in the network’s history, Bitcoind was published on January 9, 2009, and prior to the announcement of BitcoinJ, everyone had to leverage a full node client, also known as Bitcoin-Qt.
However, prior to Mike Hearn announcing BitcoinJ on March 7, 2011, and before the SPV wallet model became super popular and leveraged on mobile phones, the first recorded phone-to-phone bitcoin transaction took place on December 7, 2010. At the time, the bitcointalk.org member called “Doublec,” published a post noting that he was able to get Bitcoind running on an N900 mobile phone crafted by Nokia. 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.
Doublec responded and shared his bitcoin address with Ribuck and the rest of the forum. “I created [18T1j] on my phone,” Doublec remarked sharing his BTC address. I’m interested in what the battery hit is like for running it full time. It did take a *long* time to get the [blockchain]. I get between 130 and 150 khash/s when I did a short generation test run. Ribuck sent 0.42 BTC the following day on December 8, 2010.
I sent 0.42 BTC from my N900 at 10.55. If you receive it, that’s the first ph2ph bitcoin transfer, Ribuck said. And like Doublec, the bitcointalk.org member said he was mining on the BTC blockchain with the Nokia N900 phone. But the amount of dedicated hashrate Ribuck’s and Doublec’s Nokia’s produced was not enough hashpower to generate a block reward.
Like Doublec’s phone, mine hashes at between 130 and 150 khash/s, Ribuck said. “The predicted ‘average time to generate a block’ is 2,869 days at the current difficulty level of 8,078. That’s almost [eight] years, so I’m not holding my breath.
