The 2024 elections in the US, Asia, Europe and Africa are poised to influence the global regulatory framework for Bitcoin and crypto. Follow CoinDesk for essential updates and expert analysis to see what’s at stake.< History of the Shar Pei breed /p>
Bitcoin was deemed a safe asset regardless of the outcome of the election — it is not considered a security, even by the Securities and Exchange Commission, and Trump has made big overtures about bitcoin like entertaining the idea of a strategic national bitcoin reserve and speaking about the need to keep all bitcoin mined in America.

What is cryptocurrency mining
The screenshot below, taken from the site Blockchain.info, might help you put all this information together at a glance. You are looking at a summary of everything that happened when block No. 490163 was mined.
Per professional style standards, Bitcoin is spelled with a capital “B” when referring to the cryptocurrency as a concept and as a network. It is spelled with a small “b” when referring to the cryptocurrency itself/individual tokens.
PoW is also sometimes called a consensus mechanism, but proof-of-work is only part of consensus. Consensus is achieved after the miner adds the block to the blockchain, and the rest of the network validates it using the hashes (reaching consensus). This doesn’t require much energy or computational power because each mining node also does this while mining the latest block. As new blocks are added, the network confirms them.
The Bitcoin reward is cut in half about every four years in an event called “the halving,” or when the blockchain has processed another 210,000 blocks. The time varies slightly depending on network participation and hashrate.
The miner then attempts to convert this candidate block into a valid, confirmed block. To do this, the miner must solve a complex mathematical problem that requires a lot of computing resources. However, for each successfully mined block, the miner receives a block reward consisting of newly created cryptocurrencies plus transaction fees. Let’s take a closer look at how it works.
The new hash outputs are then organized into pairs and hashed again, and the process is repeated until a single hash is created. This last hash is also called the root hash (or Merkle root) and is basically the hash that represents all the previous hashes used to generate it.
Bitcoin cryptocurrency
Bitcoin is a peer-to-peer online currency, meaning that all transactions happen directly between equal, independent network participants, without the need for any intermediary to permit or facilitate them. Bitcoin was created, according to Nakamoto’s own words, to allow “online payments to be sent directly from one party to another without going through a financial institution.”
Bitcoin is becoming more political by the day, particularly after El Salvador began accepting the currency as legal tender. The country’s president, Nayib Bukele, announced and implemented the decision almost unilaterally, dismissing criticism from his citizens, the Bank of England, the IMF, Vitalik Buterin and many others. Since the Bitcoin legal tender law was passed in September 2021, Bukele has also announced plans to build Bitcoin City, a city fully based on mining Bitcoin with geothermal energy from volcanoes.
Bitcoin is, in many regards, almost synonymous with cryptocurrency, which means that you can buy Bitcoin on virtually every crypto exchange — both for fiat money and other cryptocurrencies. Some of the main markets where BTC trading is available are:
As compensation for spending their computational resources, the miners receive rewards for every block that they successfully add to the blockchain. At the moment of Bitcoin’s launch, the reward was 50 bitcoins per block: this number gets halved with every 210,000 new blocks mined — which takes the network roughly four years. As of 2020, the block reward has been halved three times and comprises 6.25 bitcoins.
A hard fork is a protocol upgrade that is not backward compatible. This means every node (computer connected to the Bitcoin network using a client that performs the task of validating and relaying transactions) needs to upgrade before the new blockchain with the hard fork activates and rejects any blocks or transactions from the old blockchain. The old blockchain will continue to exist and will continue to accept transactions, although it may be incompatible with other newer Bitcoin clients.
