💭 Have you ever wondered why when you send bitcoins to someone, the transaction says that all bitcoins from your address were sent?

The Bitcoin blockchain has an interesting model that allows you to record multiple «inputs» and «outputs» of funds in a single transaction. Let's say you have a friend named Bob who is celebrating something today. You want to give him 0.5 BTC and save another 0.5 BTC for the future. In that case, you’d send a transaction to the blockchain where you specify two outputs, both with 0.5 BTC.

If sending the bitcoins to Bob makes sense, where does the remaining 0.5 go? In fact, you are sending the rest of your balance to yourself, doesn’t that seem strange?

Alright, we cleared up the situation with the outputs,but what is the «input»? As an «input» you specify a link to the transaction, as a result of which you received BTC in your account. You should also realize that there can be multiple transactions to receive bitcoins, so there can be multiple «inputs». This has been implemented in order to summarize the number of bitcoins received in your account and compare it to the amount you are going to send. That is, you cannot take just any amount of BTC from the input and send it to another address, everyone is recorded counting the full amount for input and output in the transaction 🤡

There is life after the halving. It's a pity that it's not yet as rosy as crypto experts described it on Twitter 🤡

Anyway, we advise you not to worry, and we still recommend checking out our article about rewards, halving, and the market in general to those who haven't read it.

Have a great weekend!❤️

💸 The mining of bitcoin block 840,000 unfolded as follows:

As we know, the Bitcoin halving occurred at block 840,000, reducing the miner reward per block from 6.25 to 3.125 BTC.

Pre-halving, the block was notable not only because of the reduction in reward, but also because of the presence of a significant number of unusual transactions. Here's a brief summary:

The amount of Bitcoin earned by the mining pool from this block significantly exceeded the block reward. This was due to the users' desire to leave their mark in history. The largest fee found in this block amounted to a whopping 8 bitcoins! If you think this was the only one, you are wrong, as some users also paid 6.73, 2.9, 1.99 bitcoins, and so on.

Interestingly, there were also those who paid a very modest fee, around a couple of dollars. In total, the pool was able to earn just over 37.6 bitcoins in fees. It's safe to say it had a rather lucky day! In addition to the reward for mining, the total reward amounted to approximately 40.75 bitcoins, which, at the April 20 exchange rate, equaled about $2.6 million.

Incidentally, the block was found by the mining pool ViaBTC, accommodating a total of 3050 transactions.
