What Is Bitcoin (BTC)?

Bitcoin is a decentralized cryptocurrency originally described in a 2008 whitepaper by a person, or group of people, using the alias Satoshi Nakamoto lớn. It was launched soon after, in January 2009.

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 lớn permit or facilitate them. Bitcoin was created, according khổng lồ Nakamoto’s own words, to allow “online payments khổng lồ be sent directly from one các buổi party to lớn another without going through a financial institution.”

Some concepts for a similar type of a decentralized electronic currency precede BTC, but Bitcoin holds the distinction of being the first-ever cryptocurrency khổng lồ come inkhổng lồ actual use.

Who Are the Founders of Bitcoin?

Bitcoin’s original inventor is known under a pseudonym, Satoshi Nakamoto lớn. As of 2021, the true identity of the person — or organization — that is behind the alias remains unknown.

On October 31, 2008, Nakamoto published Bitcoin’s whitepaper, which described in detail how a peer-to-peer, online currency could be implemented. They proposed to use a decentralized ledger of transactions packaged in batches (called “blocks”) và secured by cryptographic algorithms — the whole system would later be dubbed “blockchain.”

Just two months later, on January 3, 2009, Nakamolớn mined the first block on the Bitcoin network, known as the genesis bloông chồng, thus launching the world’s first cryptocurrency. Bitcoin price was $0 when first introduced, & most Bitcoins were obtained via mining, which only required moderately powerful devices (e.g. PCs) và mining software. The first known Bitcoin commercial transaction occurred on May 22, 2010, when programmer Laszlo Hanyecz traded 10,000 Bitcoins for two pizzas. At Bitcoin price today in mid-September 2021, those pizzas would be worth an astonishing $478 million. This event is now known as “Bitcoin Pizza Day.” In July 2010, Bitcoin first started trading, with the Bitcoin price ranging from $0.0008 to lớn $0.08 at that time.

However, while Nakamokhổng lồ was the original inventor of Bitcoin, as well as the author of its very first implementation, he handed the network alert key and control of the code repository khổng lồ Gavin Andresen, who later became lead developer at the Bitcoin Foundation. Over the years a large number of people have contributed to lớn improving the cryptocurrency’s software by patching vulnerabilities & adding new features.

Bitcoin’s source code repository on GitHub lists more than 750 contributors, with some of the key ones being Wladimir J. van der Laan, Marteo Falke, Pieter Wuille, Gavin Andresen, Jonas Schnelli và others.

What Makes Bitcoin Unique?

Bitcoin’s most chất lượng advantage comes from the fact that it was the very first cryptocurrency khổng lồ appear on the market.

It has managed lớn create a global community & give sầu birth to an entirely new industry of millions of enthusiasts who create, invest in, trade & use Bitcoin and other cryptocurrencies in their everyday lives. The emergence of the first cryptocurrency has created a conceptual và technological basis that subsequently inspired the development of thousands of competing projects.

The entire cryptocurrency market — now worth more than $2 trillion — is based on the idea realized by Bitcoin: money that can be sent & received by anyone, anywhere in the world without reliance on trusted intermediaries, such as banks and financial services companies.

Thanks lớn its pioneering nature, BTC remains at the top of this energetic market after over a decade of existence. Even after Bitcoin has lost its undisputed dominance, it remains the largest cryptocurrency, with a market capitalization that surpassed the $1 trillion mark in 2021, after Bitcoin price hit an all-time high of $64,863.10 on April 14, 2021. This is owing in large part to lớn growing institutional interest in Bitcoin, và the ubiquitousness of platforms that provide use-cases for BTC: wallets, exchanges, payment services, online games và more.

How Much Bitcoin Is in Circulation?

Bitcoin’s total supply is limited by its software & will never exceed 21,000,000 coins. New coins are created during the process known as “mining”: as transactions are relayed across the network, they get picked up by miners & packaged into blocks, which are in turn protected by complex cryptographic calculations.

As compensation for spending their computational resources, the miners receive sầu rewards for every bloông xã that they successfully add to lớn 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 20đôi mươi, the blochồng reward has been halved three times and comprises 6.25 bitcoins.

Bitcoin has not been premined, meaning that no coins have been mined and/or distributed between the founders before it became available lớn the public. However, during the first few years of BTC’s existence, the competition between miners was relatively low, allowing the earliest network participants lớn accumulate significant amounts of coins via regular mining: Satoshi Nakamokhổng lồ alone is believed to lớn own over a million Bitcoin.

Mining Bitcoins can be very profitable for miners, depending on the current hash rate and the price of Bitcoin. While the process of mining Bitcoins is complex, we discuss how long it takes to mine one Bitcoin on vietvuevent.vn Alexandria — as we wrote above, mining Bitcoin is best understood as how long it takes to lớn mine one block, as opposed to one Bitcoin. As of mid-September 2021, the Bitcoin mining reward is capped lớn 6.25 BTC after the 2020 halving, which is roughly $299,200 in Bitcoin price today.

How Is the Bitcoin Network Secured?

Bitcoin is secured with the SHA-256 algorithm, which belongs lớn the SHA-2 family of hashing algorithms, which is also used by its fork Bitcoin Cash (BCH), as well as several other cryptocurrencies.

What Is Bitcoin’s Role as a Store of Value?

Bitcoin is the first decentralized, peer-to-peer digital currency. One of its most important functions is that it is used as a decentralized store of value. In other words, it provides for ownership rights as a physical asmix or as a unit of trương mục. However, the latter store-of-value function has been debated. Many cryplớn enthusiasts & economists believe sầu that high-scale adoption of the top currency will lead us to a new modern financial world where transaction amounts will be denominated in smaller units.

The smallest units of Bitcoin, 0.00000001 BTC, are called Satoshis (or Sats in short), in a nod to the pseudonymous creator. At Bitcoin price now, 1 Satoshi is equivalent to lớn roughly $0.00048.

The top crypto is considered a store of value, like gold, for many — rather than a currency. This idea of the first cryptocurrency as a store of value, instead of a payment method, means that many people buy the crypto lớn and hold onto lớn it long-term (or HODL) rather than spending it on items lượt thích you would typically spkết thúc a dollar — treating it as digital gold.

Crypto Wallets

The most popular wallets for cryptocurrency include both hot và cold wallets. Cryptocurrency wallets vary from hot wallets & cold wallets. Hot wallets are able khổng lồ be connected to the web, while cold wallets are used for keeping large amounts of coins outside of the internet.

Some of the top cryplớn cold wallets are Trezor, Ledger & CoolBitX. Some of the top crypkhổng lồ hot wallets include Exodus, Electrum and Mycelium.

How Is Bitcoin’s Technology Upgraded?

A hard fork is a radical change lớn the protocol that makes previously invalid blocks/transactions valid, and therefore requires all users to tăng cấp. For example, if users A và B are disagreeing on whether an incoming transaction is valid, a hard fork could make the transaction valid to users A and B, but not lớn user C.

A hard fork is a protocol tăng cấp that is not backward compatible. This means every node (computer connected khổng lồ the Bitcoin network using a client that performs the task of validating and relaying transactions) needs khổng lồ tăng cấp before the new blockchain with the hard fork activates và rejects any blocks or transactions from the old blockchain. The old blockchain will continue lớn exist and will continue to lớn accept transactions, although it may be incompatible with other newer Bitcoin clients.

A soft fork is a change to lớn the Bitcoin protocol wherein only previously valid blocks/transactions are made invalid. Since old nodes will recognise the new blocks as valid, a soft fork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules.

Some examples of prominent cryptocurrencies that have undergone hard forks are the following: Bitcoin’s hard fork that resulted in Bitcoin Cash, Ethereum’s hard fork that resulted in Ethereum Classic.

Bitcoin Cash has been hard forked since its original forking, with the creation of Bitcoin SV. Read more about the difference between Bitcoin, Bitcoin Cash và Bitcoin SV here.

What Is Taproot?

Taproot is a soft fork that bundles together BIP 340, 341 và 342 and aims khổng lồ improve the scalability, efficiency, and privacy of the blockchain by introducing several new features.

The two major changes are the introduction of the Merkelized Abstract Syntax Tree (MAST) và Schnorr Signature. MAST introduces a condition allowing the sender và recipient of a transaction to lớn sign off on its settlement together. Schnorr Signature allows users khổng lồ aggregate several signatures inlớn 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 sầu on transaction fees, as even complex transactions look lượt thích simple, single-signature ones.

Although HODLers will probably not notice a big impact, Taproot could become a key milestone lớn equipping the network with smart contract functionality. In particular, Schnorr Signatures would lay the foundation for more complex applications to be built on top of the existing blockchain, as users start switching khổng lồ Taproot addresses primarily. If adopted by users, Taproot could, in the long run, result in the network developing its own DeFi ecosystem that rivals those on alternative blockchains lượt thích Ethereum.

What Is the Lightning Network?

The Lightning Network is an off-chain, layered payment protocol that operates bidirectional payment channels which allows instantaneous transfer with instant reconciliation. It enables private, high volume & trustless transactions between any two parties. The Lightning Network scales transaction capathành phố without incurring the costs associated with transactions và interventions on the underlying blockchain.

How Much Is Bitcoin?

The current valuation of Bitcoin is constantly moving, all day every day. It is a truly global asset. From a start of under one cent per coin, BTC has risen in price by thousands of percent to the numbers you see above sầu. The prices of all cryptocurrencies are quite volatile, meaning that anyone’s understanding of how much Bitcoin is will change by the minute. However, there are times when different countries & exchanges show different prices and understanding how much Bitcoin is will be a function of a person’s location.

Is Bitcoin Political?

Bitcoin is becoming more political by the day, particularly after El Salvador began accepting it as legal tender. The country's president, Nayib Bukele, announced and implemented the decision almost unilaterally, dismissing criticism from his citizens, the Bank of Engl&, the IMF, Vitalik Buterin & many others. Since the Bitcoin law was passed in September 2021, Bukele has also announced plans to build Bitcoin City, a đô thị fully based on mining Bitcoin with geothermal energy from volcanoes.

Countries lượt thích Mexiteo, Russia & others have sầu been rumored to be candidates also to accept Bitcoin as legal tender, but thus far, El Salvador stands alone.
