$BTC Broadcasting and confirmations In the above example, Mark (via his wallet software) will broadcast his proposed transaction to the Bitcoin network. A special group of participants in the network known as 'miners' verify that Mark's keys are able to access the inputs (i.e. the address(s)) from where he previously received the bitcoin he claims to control. Miners also gather together a list of other transactions that were broadcast to the network around the same time as Mark's and form them into a block. Any miner who has completed the 'Proof of Work' is permitted to propose a new block that will be added or 'attached' to the chain and by referencing the last block. That new block is then broadcast to the network. If other network participants (nodes) agree it's a valid block (ie. the transactions it contains follows all the rules of the protocol and it properly references the previous block), they will pass it along. Eventually, another miner will build on top of it by referencing it as the previous block when proposing the next block. Any transactions that were in the previous block will now have been 'confirmed' by the next miner. As blocks are added to the chain, the number of confirmations of Mark's transaction increases.
Why do some bitcoin transaction confirmations take so long? Each block can only contain a certain number of transactions, and that number is determined largely by the space available in each block, or the 'block size,' which is 1MB. The limited space gives rise to the fee market, where miners, who collect fees, choose to include in the next block only those transactions which have included a high enough fee. Thus higher fees act as incentive for miners to prioritize your transactions.
Note that the block size is an arbitrary limit, but the Bitcoin community has chosen to keep the block size as small as possible in order to make it easier for people to operate Bitcoin nodes. Bitcoin Cash, which is a fork of Bitcoin, has a larger block size and therefore requires much lower fees for transactions.
$BTC In short, Bitcoin is a digital form of money that runs on a distributed network of computers (nodes). In a broader sense, though, many people often use the word Bitcoin to refer to a few different things: a digital currency, a decentralized public ledger, a protocol, or simply the big ecosystem that encompasses all of these. However, there are some fundamental differences between these functionalities. First, Bitcoin is the name of a peer-to-peer (P2P) digital currency, which is sometimes referred to as bitcoin (with lower “b”) or simply BTC. Bitcoin is a cryptocurrency, which means it is a digital currency that is protected by cryptographic techniques. It was the first cryptocurrency that came into existence, and the first Bitcoin block - known as the genesis block (or block 0) - was mined on the 3rd of January 2009. Second, the Bitcoin decentralized public ledger is what we call blockchain. Despite being closely related, Bitcoin and blockchain are different concepts. The blockchain technology is what maintains the whole structure that allows Bitcoin transactions to be broadcasted and recorded in a trustless and secure way. Note that, in this context, trustless means that the blockchain system does not rely on any kind of trust to function as it is backed by computer code and mathematical algorithms. Thus, the Bitcoin blockchain works as a decentralized digital ledger that publicly lists all confirmed BTC transactions. Lastly, the term Bitcoin was also used to refer to the protocol that is being continually developed as an open source software. In 2014, however, the original Bitcoin client software was officially rebranded to Bitcoin Core to avoid further misunderstanding. As an open source software, Bitcoin Core counts with numerous contributors worldwide. Bitcoin was conceptualized by a person (or group) under the pseudonym Satoshi Nakamoto. The idea was to create a unique digital payment system that would permit borderless financial transactions to occur without the need for mediators like banks or governments.

Binance cryptocurrency exchange and BNB token were established in 2017. BNB token was initially an ERC-20 token on the Ethereum blockchain. In 2019, it migrated to Binance Exchange’s propriety blockchain called Binance Chain, and eventually became the fuel for Binance Smart Chain (BSC), which launched in September 2020. Due to the network’s high transaction speed, low transaction cost, and EVM compatibility, BSC quickly gained traction as the DeFi movement took off and Ethereum suffered from chronic congestion and high fees.
In February 2022, Binance Smart Chain was rebranded as BNB Smart Chain. BNB Smart Chain is itself part of the BNB Chain ecosystem of blockchains, which consists of BNB Beacon Chain (the staking and governance layer), BNB Smart Chain (the smart contract execution layer), ZkBNB (a zero-knowledge proof rollup for scaling), and BNB Greenfield (a decentralized data storage platform). How can you use BNB and BNB Smart Chain? Anyone can buy, sell, send, receive, and hold BNB in the Bitcoin.com Wallet app. Advanced users also have the option to directly interact with Decentralized Apps (dApps) on the BNB Smart Chain network using the Bitcoin.com Wallet (via WalletConnect). dApps on BNB Smart Chain enable DeFi use cases like trading, borrowing and lending, prediction markets, crypto derivatives, synthetic assets, NFTs, and more. For an up-to-date list of the top decentralized applications on BNB Smart Chain, please refer to DAppRadar. To learn how to connect to dApps in the Bitcoin.com Wallet app, please see this guide. For more information about BNB Smart Chain, please refer to this document. Bridging between BNB Smart Chain and Ethereum You can bridge select Ethereum cryptoassets to BNB Smart Chain using the officially recommended Celer cBridge. Bridging will take a certain amount of time, which the bridge will estimate for you. After that, you can do most things you can do on Ethereum such as swap, borrow/lend

$BTC Bitcoin is back in the news. Hackers tried to scam Twitter users to send them money via Bitcoin using high-profile social media accounts.
While we're all used to the idea of digital currency - spending and receiving money that isn’t physically in front of us - cryptocurrencies, like Bitcoin, remain a mystery.
What is Bitcoin mining? How might we use money in the future? And can we even trust cryptocurrencies?
In this Q&A, we ask Dr William John Knottenbelt, director of the Imperial College Centre for Cryptocurrency Research and Engineering, to help us better understand this cryptic kind of currency.
1. What is Bitcoin and how does it work?
Bitcoin is a form of digital money. This means it doesn’t have a physical form. Instead, units of digital currency are traded over a computer network that has some unique properties:
It does not have any central points of control (there are no ‘banks’)
It does not have any central points of transaction storage (a central database that holds a record of all the transactions made).
Instead, it operates over a global network with thousands upon thousands of nodes - a machine within a network like a computer or some other device - which together process and store transactions.
Having thousands of nodes makes it difficult to have a common record of all the transactions - but a technology known as blockchain makes this possible.
Blockchain is a shared transaction record - it prevents anyone from ‘double spending’ bitcoins and makes it extremely hard for anyone to alter historical transactions. It is very hard, if not impossible, to shut down or interfere with. Glossary

About 36% of Bitcoin was traded in the past month, hinting at a possible market peak between Q1 and Q2 of 2025, recovering from below $95,000.
$BTC Bitcoin is a cryptocurrency, a digital asset that uses cryptography to control its creation and management rather than relying on central authorities.Originally designed as a medium of exchange, Bitcoin is now primarily regarded as a store of value. The history of bitcoin started with its invention and implementation by Satoshi Nakamoto, who integrated many existing ideas from the cryptography community. Over the course of bitcoin's history, it has undergone rapid growth to become a significant store of value both on- and offline. From the mid-2010s, some businesses began accepting bitcoin in addition to traditional currencies. Number of bitcoin transactions per month.
Background: Prior to the release of bitcoin, there were a number of digital cash technologies, starting with the issuer-based ecash protocols of David Chaum and Stefan Brands.The idea that solutions to computational puzzles could have some value was first proposed by cryptographers Cynthia Dwork and Moni Naor in 1992.
31 October 1996 NSA paper
edit
12 years prior to creating Bitcoin the NSA published the white paper HOW TO MAKE A MINT: THE CRYPTOGRAPHY OF ANONYMOUS ELECTRONIC CASH
Adam Back: The idea was independently rediscovered by Adam Back who developed hashcash, a proof-of-work scheme for spam control in 1997.The first proposals for distributed digital scarcity-based cryptocurrencies were Wei Dai's b-money and Nick Szabo's bit gold.Hal Finney developed reusable proof of work (RPOW) using hashcash as its proof of work algorithm.
In the bit gold proposal which proposed a collectible market-based mechanism for inflation control, Nick Szabo also investigated some additional aspects including a Byzantine fault-tolerant agreement protocol based on quorum addresses to store and transfer the chained proof-of-work solutions, which was vulnerable to Sybil attacks, though.
#BitcoinHashRateSurge What is Bitcoin? #The world’s first widely-adopted cryptocurrency. With Bitcoin, people can securely and directly send each other digital money on the internet.
Bitcoin was created by Satoshi Nakamoto, a pseudonymous person or team who outlined the technology in a 2008 white paper. It’s an appealingly simple concept: bitcoin is digital money that allows for secure peer-to-peer transactions on the internet.
Unlike services like Venmo and PayPal, which rely on the traditional financial system for permission to transfer money and on existing debit/credit accounts, bitcoin is decentralized: any two people, anywhere in the world, can send bitcoin to each other without the involvement of a bank, government, or other institution.
Every transaction involving Bitcoin is tracked on the blockchain, which is similar to a bank’s ledger, or log of customers’ funds going in and out of the bank. In simple terms, it’s a record of every transaction ever made using bitcoin.
Unlike a bank’s ledger, the Bitcoin blockchain is distributed across the entire network. No company, country, or third party is in control of it; and anyone can become part of that network.
There will only ever be 21 million bitcoin. This is digital money that cannot be inflated or manipulated in any way.
It isn’t necessary to buy an entire bitcoin: you can buy just a fraction of one if that’s all you want or need.

What makes Bitcoin different?
Bitcoin is a decentralized digital asset. Let’s break that down.
Bitcoin spans many traditional assets, such as cash and gold. For example, you can use it like money or as a store of value.
Another key to what makes Bitcoin different is its decentralized and “trustless" model. This means that trusted third parties (middlemen such as banks) aren’t necessary with Bitcoin. These third parties act as go-betweens, and are often called intermediaries.
In traditional finance there is always a business (usually more than one) in between your transactions.
What may seem like one go-between is often many more. Take a stock trading app for example. There can be up to a dozen intermediaries between you and a seller, each extracting a fee for their services! Additionally, unlike almost all modern financial transactions which are electronic, physical cash and Bitcoin are similar in that they can be transacted directly, without third parties, and without asking for permission to create an account.
Exchanging cash directly doesn’t require intermediaries, but the creation of cash is solely dependent on a trusted third party, such as a central bank. The creation of new Bitcoin, by contrast, occurs programmatically and is limited to 21 million units. More on this later.

$BTC Is Bitcoin safe to use? Is cryptocurrency safe? Crypto is bought and sold on the internet, which means it comes with risks, just as there are with any asset you purchase online. In general, remember that crypto is highly volatile, and may be more susceptible to market manipulation than securities. #Share1BNBDaily
$BTC Who is the CEO of Bitcoin? Bitcoin does not have a CEO or a central banker at its helm and, in fact, is not controlled by any single person or entity. Nonetheless, Bitcoin was created by someone and is governed by a variety of community stakeholders through a system that is referred to as rough consensus. #Share1BNBDaily

$BTC The Unicode symbol: The Unicode symbol for bitcoin (₿) was introduced in Unicode 10.0.0 on June 20, 2017. This important step established bitcoin as a currency symbol alongside the US Dollar ($), Euro (€), and others. As of mid-2021, few fonts support the symbol. #Share1BNBDaily
$BTC On November 1, 2010, a user named bitboy proposed a new icon and set of promotional graphics on the Bitcointalk forum (archive.org, bitcointalk.org). This iteration added a flat style, the hex color #F7931A, and a 14-degree rotation of the B. This interpretation of the bitcoin logo is still ubiquitous today. #Share1BNBDaily
On February 24, 2010, Satoshi posted an updated icon that adopted the capital “B” with two vertical lines (archive.org, bitcointalk.org). Satoshi requested that all derivative works be placed in the public domain. #Share1BNBDaily
