Transactions – processed payout not included in my blockchain wallet

The following are the transaction details for the transaction that are not in my blockchain wallet.

Transaction stack: f28888630e090d083ce2be5658f526b148d3e8259a33bbcfa58063cc13e8a4c0

Wallet address: 1NUf8TSGw5nuDpUre42n927dKhpDmeMdTo

Please note that I previously have some bitcoins from 1HG43hWnE7ZZAcbhA3umYxB7JgPU99kATJ with the same wallet. So for the above transaction, I simply took the above wallet address and forwarded it to those who should send me other bitcoins.

The transaction appears in the Blockchain Explorer, but not in my Blockchain wallet.

Please help me, how can I recover the bitcoins if possible.


Blockchain – Why can a miner dig up multiple blocks at once?

I'm new to Bitcoin and Blockchain and have just reworked the site. There is a question that confuses me. I think a miner digs up blocks many times in an hour. For example, this miner digs four blocks between 6:00 and 7:00. Is it possible that this miner controls 51% of the CPU? And could this break the entire Bitcoin blockchain?

I hope someone can answer me, thanks!


Transactions – How to check the transformation of raw values ​​in the blockchain?

Is there a solution for verifying a transformation of raw values ​​in the blockchain?

For example, you have a (private, legitimate) blockchain solution to check how many apples are in your storage. New apples arrive at random every 1 to 5 minutes. The same applies to outgoing apples.

After each hour that has passed, you want to calculate the apples that have arrived within the last hour. After each day you want to calculate the average of apples that arrived per hour.

Does Ethereum (and others) solve this with smart contracts?
What are alternative approaches?

To make it more complex, let's say the transformation itself is very complex and can not be stored in a smart contract – like using a neural network that can not be replicated to all nodes. How can the other nodes confirm that the transformation was done correctly and trustingly and save the result only in the blockchain?

Consensus – Can I have a blockchain that has not been mined or validated?

I'm ready to use blockchain technology to implement the voting system. Therefore, I plan to create a private network that consists only of nodes that people vote on, so I do not want a miner or examiner. Is it possible to do it? Is there a consensus that allows this? Is it also possible to avoid double spending with smart contracts? (I plan to use a hash of voter fingerprints as an address, so I can restrict a person to vote only once with smart contracts.)
I am sorry for any misunderstandings, as I am still very new to the blockchain!

Were there projects that worked to create a stable coin that is not based on a transparent blockchain?

Stablecoins have applications such as the CDP Dai by Makerdao and a privacy coin like Monero. But is there a project that combines these two technologies together to create a stable coin that is also private, and you can not see how much money was sent and where it went?

Blockchain – PivX Fork | After the last PoW block, PoS (proof of stake) will not be activated [Developer]

I played with my tenth fork (never released), this time it's PivX.

My mission is to exam the proof-of-work segment and the Proof-of-Stake segment.

After completing the proof-of-work cycle until the variable "nLastPOWBlock" in chainparams.cpp, line: 118.

Enter image description here

I'm trying to find all variables related to proof-of-stake activation

Enter image description here

  1. Valid time = true
  2. Peer relationships = true
    Enter image description here
  3. Purse unlocked = true
  4. Mintable / enough credits = true
    Enter image description here
  5. Master node synchronized = true

Enter image description here

  1. Stakeout Status = not correct

So my question is this: are members here familiar with PivX enough to know what's needed to activate the proof-of-stake segment when PoW is over?

Implement PKI with Blockchain

Many recent studies suggest ways to decentralize PKI. One of them is the implementation of the PKI in the blockchain. However, there is still a certification authority. Is the PKI not yet centralized?
