Hello, if you have fun facts about Bitcoin that can be see with a Bitcoin explorer, please share it ! Here fun facts I know with source :



The infamous Mark Karpeles made a bugged php script and sent 2 609 BTC to broken address. As you can see below, one of these address start with "s-" but regular bitcoin address start with "1","3" or "bc1" :

You can write message inside bitcoin blockchain. And someone wrote the hash of a famous virus. So if you were a bitcoin node back then, for a time, all antivirus was detecting your blockchain as a virus and deleted all your files ! Making you downloading again. I don't know more details, just citing out of my memory !


First bitcoin transaction (excepte for coinbase that are block reward) at block #170 :

Block difficulty is retarget every 2016 blocks, but the first chance on block difficulty start at block #32256. Between block #1 and block #32256 the average block time was 16minutes. So retarget only works if block times are under 10minutes + difficulty above 1.00 !

Here's an interesting (not so fun) fact: Did you know that almost 20% of Bitcoin has been lost forever ?

It is estimated that around 3.7 m BTC (or around 155 billion dollars) is either locked in hardware wallets with no means to recover it or people passing away without sharing their bitcoin holdings with anyone.

And there's also satoshi nakamoto which is believed to be holding around 1 million BTC (5 % of the supply) in the many thousands addresses that he controls.


I tried to post an address of satoshi that could be seen with a bitcoin explorer but didnt manage to find any (if anyone could help ?).

I think we have this kind of thread before:

• Fun Facts about Bitcoins
• Fun Facts of Bitcoin
• 40 Interesting Facts About Bitcoin You Don't Know
• Payment No. 1: A Closer Look at the Very First Bitcoin Transfer

So perhaps it's better to cross reference with it with the old thread that I posted and see if the OP missed something or if it has been posted before.

Are you sure it was Satoshi's address/es?

Someone wrote the bitcoin whitepaper in this bitcoin transaction. As you can see, address are unusual, start with "m-" !

If you have a Bitcoin node installed, you can get the whitepaper from the blockchain with this command:

Code:

bitcoin-cli getrawtransaction 54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713 true | jq -r '.vout[].scriptPubKey.asm' | cut -c3- | xxd -p -r | tail +9c | head -c 184292 > bitcoin.pdf

one of these address start with "s-" but regular bitcoin address start with "1","3" or "bc1" :

That is not a bitcoin address and there is no string to start with a letter such as "s-" associated with that script. This particular block explorer called blockchair has its own undocumented way of assigning a seemingly random string that usually start with a letter like "s" to any output script that it doesn't recognize. This is not universal standard and we don't even know how the conversion takes place (it is undocumented).

Largest transaction in bitcoin : 500,000.00 BTC sent in 2011 !

Normally we report the total input amounts as the value size of a transaction not a single output it creates. The total value of this particular transaction is 550k.

Block 478558 was the last block Bitcoin and BitcoinCash had in common, so block #478559 are different :

This is more of a bcash fun fact not bitcoin's. Specially since bcash was neither the first nor the last shitcoin that copied bitcoin's code and blockchain. There were others before it and a lot after it. For example a shitcoin called BitCore forked at block #463604

Just after BTC big fork, a miner wrote "FUCK BITCOIN CASH" on a block :

Funny but I'd say it is still a bcash fun fact

[Kong Hey Pakboy]

I wonder what's the 500k bitcoin was used and who received and if it's still existing to this day, that's the most fascinating thing in this trivias, the Mark Karpeles one though, that's a really frustrating one, 2k bitcoins gone in just a press of a button.

Well said! I actually experimented myself with an altcoin (before bcash came up) just to experience how it was to be an early miner on a very weak computer, and that coin, whose name I even forgot, even had some liquidity on cryptopia

Bitcoin Classic is an earlier Bcash and is somehow still alive!

Agree to cross-reference and enrich existing threads too.

My fun fact: Early Bitcoin users used to spell it as "BitCoin" (capital B and capital C) and some sites still use this style of spelling. I never found out why, does anyone know?

If you want to know more about Bitcoin fun fact that exists within the blockchain itself, you should check about BTC RPC explorer fun fact, the application also curating interesting fact within its app. For an example click the below image:


You can also see the full list without running the explorer by looking at their source code here.

Amazing thanks !


I will add something that I found recently too :


Block difficulty is retarget every 2016 blocks, but the first chance on block difficulty start at block #32256. Between block #1 and block #32256 the average block time was 16minutes. So retarget only works if block times are under 10minutes + difficulty above 1.00 !
