Title: Questions regarding transaction
Post by: Taytrader on October 07, 2017, 09:58:24 PM
I sent 50 BTC from one of my hardware wallets to another one of my hardware wallets. Everything transacted just fine, but when I look up my transaction ID on blockcypher.com, all sorts of addresses and amounts show up. Will someone please explain all these to me? Back in the day, if I sent a BTC from one of my wallets to another, it just showed 1 sending address and 1 receiving address. Now I see all sorts of weird stuff.

Transaction ID= 07b9520df4a5081118ca2170741dc0d85fe56cf5b54f44d7bdc6fc1ab94e3a7a

Why are there 13 inputs? Why are there 2 outputs totaling 88 BTC? For a minute I thought the 2 outputs totaled up to the amount of BTC in the sending wallet, but my sending wallet has 95 BTC in it, not 88. Please help me understand all of this.

Thanks

Sounds like you need to read this: https://en.bitcoin.it/wiki/Coin_analogy

And this: https://en.bitcoin.it/wiki/Change

You attempted to send 50 BTC, but your biggest UTXO looks to have been 49.99915808 BTC, so your wallet added in extra inputs to make up a total of over 50... Not sure why it needed to use another 12 inputs when pretty much any of the other ones with would have been plenty for 50+fee! Possibly some weird glitch in the UTXO selection algorithm that your wallet is using?? ???

Anyway, it totalled up 88+ BTC, but you only wanted 50, so it put the remaining 38 into a change address in your wallet...

That's exactly the information I was looking for, but could not find it. Thanks for the links.

Always double check your information before sending because that's big one if you loose such amount of btc.
