The root hash and the hash of the previous block cannot be changed, so miners must change the nonce value several times until a valid hash is found. In order to be considered valid, the output (block hash) must be less than a certain target value determined by the protocol. https://portal-credo.info/ In Bitcoin mining, the block hash must start with a certain number of zeros — this is called the mining difficulty.
The first miner to find the solution to the problem receives bitcoins as a reward, and the process begins again. This reward is an incentive that motivates miners to assist in the primary purpose of mining: to earn the right to record transactions on the blockchain for the network to verify and confirm.
Every miner on the network does this until a hash and nonce combination is created that is less than or equal to the target hash. The first to reach that target has their proposed block added to the chain, receives the reward and fees, and a new block is opened. Once that block fills up with information (about one megabyte), it is closed, encrypted, and mined.

“This investigation, the first of its kind, identified numerous fraudsters in the cryptocurrency industry. Wash trading has long been outlawed in the financial markets, and cryptocurrency is no exception.

That’s part of a rally across cryptocurrencies and crypto-related investments since Trump won the U.S. presidential election. Analysts credit much of the recent gains to an anticipated “crypto-friendly” nature of the incoming administration, which could translate into more regulatory clarity but also leeway.
Gensler slow-walked — but eventually approved — a bitcoin exchange-traded fund, allowing people to add exposure to cryptocurrencies in their retirement accounts. In January 2024, Gensler’s X account was hacked, and his account falsely posted that the long-awaited bitcoin ETF was open for business, temporarily sending cryptocurrencies surging.

The two major changes are the introduction of the Merkelized Abstract Syntax Tree (MAST) and Schnorr Signature. MAST introduces a condition allowing the sender and recipient of a transaction to sign off on its settlement together. Schnorr Signature allows users to aggregate several signatures into one for a single transaction. This results in multi-signature transactions looking the same as regular transactions or more complex ones. By introducing this new address type, users can also save on transaction fees, as even complex transactions look like simple, single-signature ones.
This negative sentiment appears to have been broken, with a number of corporate behemoths buying up Bitcoin since 2020. In particular, business intelligence firm MicroStrategy set the pace after it bought $425 million worth of Bitcoin in August and September 2020.

Furthermore, some who defend Bitcoin argue that the gold and banking sector — individually — consume twice the amount of energy as Bitcoin, making the criticism of Bitcoin’s energy consumption a nonstarter. Moreover, the energy consumption of Bitcoin can easily be tracked and traced, which the same cannot be said of the other two sectors. Those who defend Bitcoin also note that the complex validation process creates a more secure transaction system, which justifies the energy usage.
