So I tried sending out btc on my blockchain app but it keep saying code:-25 error,:bad-txns-input-missingorspent I don’t understand what this is and I would need help on how to solve this thanks in advance
I want to create a database of META tags associated with BTC UTXOs and ETH accounts. Eventually I would like to do the same for all major blockchains and their (multiple in some cases) assets. Ideally I’d want to store all this info on a single distributed database, most likely a new blockchain. I understand that this will be a huge amount of info though but provided the fact that these MEYA tags will be opt-in only this might not be as dramatic as it sounds. What is the most efficient way to go about with this project?
I started buying crypto in 2018. I’m holding on for the ride…boom or bust. However, that doesn’t mean I’ll ever understand it, and I certainly don’t need to jump on any anarchic or utopian blockchain bandwagons.
My most pressing question is this: who or what am I supporting when I buy bitcoin or ether? Did I unwittingly support the overthrow of governments when I bought crypto?
Lastly, who benefited the most in the early days of crypto? The miners? Investors who got in early? And who stands to benefit now? Where is all the money going? (By money I still mean US Dollars!)
What can I do to recover my funds?
I had a few transactions sitting in my imported address and not in my actual wallet ( at that time I didn’t know I had to move the funds from the imported address to the main wallet). I only found out recently when I changed phones and forgot my login since it didn’t use the blockchain app for a while. I used the 12 word phrase to recover the account and when I regained access, the balance was zero. Now I know that the 12 word phrase does not back up the imported addresses.

There are transactions, and blocks. Both have their own unique identifiers, which are calculated as a hash of all the data in it.
When a transaction is included in a block, its hash (txid) doesn’t change. It just becomes part of a block. That block also has a hash, which depends on the hash of the parent block, as well as on the hash of all transactions included in it.
So no, not all transactions share the same hash. Their hash is simply the hash of their data, and once created and signed, that hash cannot change without invalidating the signatures. Including it in a block doesn’t change that.
I used some coinjoined BTC coins from my from my WASABI wallet to exchange for ADA on Godex. I sent coins from Wasabi wallet but had Godex deposit them in my Exodus wallet. It was around 500€.
There was no problem with the exchange with Godex but all the other BTC coins in my wallet that were coinjoined were sent to Blockchain and remain there unconfirmed. I did not send them. The coins are gone from my wallet but I can see them on the blockchain.
All these coins in my Wasabi wallet were not conjoined together and the same time.
They were sent in 7 separate transactions from my Exodus wallet to separate addresses in my Wasabi wallet and then coinjoined separately. Now all these separate coinjoin coins are listed as an INPUTS on the blockchain. Unconfirmed
The BTC coins seen on Blockchain are are Unconfirmed and UNspent
HOW DO I GET THEM BACK IN MY WASABI WALLET?
How do miners decide how many transactions they should have in a block in order to mine 1 bitcoin?
The amount of work miners do has no impact on the amount of Bitcoin they make. The block subsidy is a fixed amount, and transaction fees are determined from transactions. Mining 1 Bitcoin does not require some specific amount of work.
Miners determine how many transaction they should have by determining how much in transaction fees they stand to gain from including those transactions. This is typically done by ordering all known unconfirmed transactions by their fee rate. Then the miner just includes as many transactions that is allowed by the consensus rules, starting from the transaction with the highest transaction fees.
When miners compete to find the “nonce” that has the smallest possible hash number, would it be faster/easier to find the “nonce” if there are fewer transactions?
No. The number of transactions has no significant effect on the difficulty of a block or the amount of work required to mine a block. While including more transaction nominally requires computing more hashes, this is negligible in the grand scheme of things, especially since this calculation is only done once for a set of nonces and extraNonces.
Do all miners try to solve a solution where all the transactions should be the same in a single block and everyone’s trying to compete to finding the nonce and hash?
Everyone chooses their own set of transactions to include. Everyone is making their own block, just each block points to the same parent block.
Or is it random, and its just whoever finds a hash the quickest, saves those transactions and adds it to the blockchain?
It is entirely random. It’s however finds a block first and broadcasts it.
Also, I noticed looking at btc.com, there are blocks being mined less than 10 minutes back to back, I thought it needs to be 10 minutes to be mined?
The average time between blocks is 10 minutes, but that is an average, not a requirement. Blocks can be found in less than 10 minutes, or more than 10 minutes. The average block is ~10 minutes.
A couple of years ago I set up a bitcoin wallet on blockchain. How do I retrieve any bitcoin left in if I don’t remember all my passcode info. I’m VERY tech ignorant! HELP!! I’m on disability and need every penny I can find. Anyone kind enough to offer ideas or suggestions?
There may be a reward if I can access my wallet and what’s in it! Please and thank you in advance
I have two BTC accounts on a Ledger S Nano hardware wallet, which I can check via the Ledger Live software. I’ve transferred BTC many times already, to my own accounts and to other people, and never had a problem before.
Today, I tried to transfer some BTC from one account (Bitcoin Current) to another (Bitcoin Savings). The BTC went out of the Bitcoin Current account instantly and has now been confirmed 36 times. However, the BTC did not appear on my Bitcoin Savings account and several hours have now passed. There is also no record of the transfer in the Bitcoin Savings account, i.e. it doesn’t say ‘received x BTC’ as usual.
I transferred the money in the same way as I normally do:
- Click on the account where the BTC will be transferred
- Click receive
- Connect Ledger S Nano
- Confirm Bitcoin address shown in software on Ledger S Nano
- Copy the address (Here I copied the address to Notepad, then copied again from Notepad before using, which I don’t think I’ve done before)
- Click on the account from which to send BTC
- Enter amount to be sent, Bitcoin address, etc., and confirm transaction on Ledger S Nano.
I would like to know how I can check where the transaction went wrong. Is there a way of confirming that the Bitcoin address I used does actually belong to my Bitcoin Savings account? Is there a way of checking whether somewhere in the process I accidentally sent BCH to a BTC account or vice versa (although I’m not sure how this would happen?). I found another forum where someone had an issue with an address that was incorrectly copied/pasted or had extra characters added in to it or something, how can I check this?
Thanks in advance for any help here
