A simple but cryptic tweet from Jack Dorsey, Founder and CEO of Twitter and payments firm Square, has sparked a debate about the meaning of the post, and whether the well-known Bitcoin (BTC) advocate has any BTC-related plans that have yet to be announced.

As pointed out by many users replying to the thread, the tweet, saying just “705742,” likely refers to a block number on the Bitcoin blockchain. A block with that number was indeed mined on Tuesday at 20:14 UTC, but it is still unknown what else is special about the particular block.

Twitter users were quick to pull up the bitcoin block explorer to see if there was anything unusual about block 705742, which at that point had yet to be mined. However, little out of the ordinary could be found.

Others, meanwhile, joked that the number could be Dorsey’s “[end of year] price target for bitcoin,” or that it could be somehow related to “Moscow time,” – bitcoin slang for the value of 1 USD in satoshis.

Speculating further, one user on Reddit suggested that the block number could be the first block to be mined by a new mining system that Dorsey has proposed.

“Maybe the first block that Square mined as part of their [research & development] for a potential public mining platform,” the user wrote, before adding that it looks like the wallet that received the block reward already has both in and outbound transactions worth almost USD 2bn. “Seems like a plausible volume for Square/Cashapp,” the user added.

However, according to various Bitcoin blockchain explorers, the block in question included 2,787 transactions and was actually mined by the BTC.com pool. Moreover, the block was mined almost an hour after the tweet was published.

In either case, as reported, the latest tweet from the Twitter CEO followed another thread from last Friday, where Dorsey said that Square is considering building “a bitcoin mining system based on custom silicon and open source.” 

“Mining needs to be more distributed” and it “should be as easy as plugging a rig into a power source,” Dorsey wrote, asking his followers what the biggest barriers are for people who want to run miners.

At 08:16 UTC, BTC trades at USD 64,042 and is up by 3% in a day and 14% in a week.
