Submit A Request Chat with a live agent. Back to Coinbase. Bitcoin Glossary. This is a glossary of terms related to Bitcoin and Coinbase.

Address : A string of letters and numbers which bitcoins can be sent to and from. A bitcoin address can be shared publicly, and like sending a message to an email address, a bitcoin address can be provided to others that wish to send you bitcoin.

Attack Surface : In computer security, an attack surface refers to the number of places where a malicious user may be able to gain access to a system. In general, a computer running more complex software has a higher attack surface than one running simpler software. Bitcoin : The first global, decentralized currency. Bits : A sub-unit of one bitcoin. There are 1,, bits in one bitcoin. Block : A collection of Bitcoin transactions that have occurred during a period of time typically about 10 minutes.

If the blockchain is thought of as a ledger book, a block is like one page from the book. Blockchain : The authoritative record of every Bitcoin transaction that has ever occurred. BTC : An abbreviation for the bitcoin currency.

Centralized : Organized such that one or more parties are in control of a service. Chargeback : The reversal of a bank payment or money transfer after it was authorized. Sometimes used to commit fraud. Cold Storage : The storage of Bitcoin private keys in any fashion that is disconnected from the internet. Typical cold storage includes USB drives, offline computers, or paper wallets.

Cold Wallet : A Bitcoin wallet that is in cold storage not connected to the internet. Confirmations : A bitcoin transaction is considered unconfirmed until it has been included in a block on the blockchain, at which point it has one confirmation. Each additional block is another confirmation. Coinbase requires 3 confirmations to consider a bitcoin transaction final. Cosigner : An additional person or entity that has partial control over a Bitcoin wallet. Cryptocurrency : A type of currency that uses cryptography instead of a central bank to provide security and verify transactions.

Bitcoin is the first cryptocurrency. Cryptography : In the context of Bitcoin, cryptography is the use of mathematics to secure information. Cryptography is used to create and secure wallets, sign transactions, and verify the blockchain. Decentralized : Without a central authority or controlling party.

Bitcoin is a decentralized network since no company, government, or individual is in control of it. Distributed : A distributed network is designed so that there is no central server or entity that others must connect to. Instead, network participants connect directly to each other. Bitcoin is a distributed network. Encryption : The use of cryptography to encode a message such that only the intended recipient s can decode it.

Bitcoin uses encryption to protect wallets from unauthorized access. Hash : 1 A unique identifier of a Bitcoin transaction. Hot Wallet : A Bitcoin wallet that resides on a device that is connected to the internet. A wallet installed on a desktop computer or smartphone is usually a hot wallet. Ledger : A physical or electronic log book containing a list of transactions and balances typically involving financial accounts. The Bitcoin blockchain is the first distributed, decentralized, public ledger.

M of N : The number of cosigners that must provide signatures M out of the total number of cosigners N in order for a multi-signature bitcoin transaction to take place. A common M of N value is "2 of 3" meaning two of the three cosigners' signatures are required.

Miner : A computer or group of computers that add new transactions to blocks and verify blocks created by other miners. Miners collect transaction fees and are rewarded with new bitcoins for their services.

Multi-Signature : Also called multisig. A bitcoin transaction that requires signatures from multiple parties before it can be executed. Coinbase multisig vaults use this type of technology. Node : A participant in the Bitcoin network. Nodes share a copy of the blockchain and relay new transactions to other nodes.

Bitcoin is an open source project and arguably the first open source money. Paper Wallet : A type of cold storage wallet where private keys are printed on a piece of paper or other physical medium. Peer to Peer : A type of network where participants communicate directly with each other rather than through a centralized server. The Bitcoin network is peer to peer.

Private Key : A string of letters and numbers that can be used to spend bitcoins associated with a specific Bitcoin address. Proof of Work : A piece of data that requires a significant amount of computation to generate but requires a minimal amount of computation to be verified as being correct. Bitcoin uses proof of work to generate new blocks.

Protocol : The official rules that dictate how participants on a network must communicate. Bitcoin's protocol specifies how each node connects with the others, how many bitcoins will exist at any point in time, and defines other aspects of the network. Public Key : A string of letters and numbers that is derived from a private key.

A public key allows one to receive bitcoins. QR Code : A digital representation of a bitcoin public or private key that is easy to scan by digital cameras. QR codes are similar to barcodes found on physical products in that they are a machine-friendly way to embody a piece of data. Signature : A portion of a Bitcoin transaction that proves that the owner of the private key has approved the transaction. There are million satoshis 8 decimal places in one bitcoin.

Satoshi Nakamoto : The inventor of Bitcoin. SHA : The specific hash function used in the mining process to secure bitcoin transactions. Transaction : An entry in the blockchain that describes a transfer of bitcoins from address to another. Bitcoin transactions may contain several inputs and outputs. Transaction Fee : Also known as a "miner's" fee, a transaction fee is an amount of bitcoin included in each transaction that is collected by miners.

This is to encourage miners to add the transaction to a block. A typical bitcoin fee amount is 0. Vault : A type of Bitcoin wallet provided by Coinbase. Vault accounts add additional time-lock and security measures to protect your funds. Wallet : A collection of Bitcoin private keys used to spend bitcoins. Still can't find what you're looking for?

By using our site, you acknowledge that you have read and understand our Cookie Policy , Privacy Policy , and our Terms of Service. When I receive bitcoins I see a certain number of "confirmations" in the client. What do these mean? Why do most sites make me wait for 6 "confirmations" before a purchase will go through? Bitcoin confirmations represent the number of blocks in the block chain that have been accepted by the network since the block that includes the transaction. In simpler terms it represents the difficulty of a double spend attack. With zero confirmations no proof of work has been done, so you can't tell if anyone considers the transaction valid. Even with a single transaction it is possible for an attacker to pre compute a single block.

How many Bitcoin Confirmations are Enough?

Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.

Bitcoin what does 2 confirmation mean bitcoin the first implementation of a concept called "cryptocurrency", which was first described in by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority.

The first Bitcoin specification and proof of concept was published in in a cryptography gitcoin list by Satoshi Nakamoto. Satoshi left the project in late without revealing much about. The community has since grown exponentially with many developers working on Bitcoin. Satoshi's anonymity often raised unjustified concerns, many of which are linked to misunderstanding of what does 2 confirmation mean bitcoin open-source nature of Bitcoin.

The Bitcoin protocol and software are published openly and this web page developer around the world can review the code or make their own modified version of the Bitcoin software. Just like current developers, Satoshi's influence was limited to the changes he made being adopted by others and therefore he did not control Bitcoin.

As such, the identity of Bitcoin's inventor is probably as relevant today as the identity what does 2 confirmation mean bitcoin the person who invented paper. Nobody owns the Bitcoin network much like no one owns the technology behind email. Bitcoin is controlled by all Bltcoin users around the world. While visit web page are improving the software, they can't force a change in the Bitcoin protocol because all users are free confirmatiom choose what software and version they use.

Butcoin order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can men work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to nitcoin this consensus.

This is how Bitcoin works for most users. Behind the scenes, the Bitcoin network is sharing a public ledger called the "block chain". This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction.

The authenticity of each concirmation is clnfirmation by digital signatures corresponding to the sending addresses, allowing all users to bbitcoin full control over sending bitcoins from their own Bitcoin addresses. In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. This is often called "mining". To learn more about Bitcoin, you can consult the dedicated page and the original paper.

There are a growing number of businesses and individuals using Bitcoin. This includes brick-and-mortar businesses like restaurants, apartments, and law firms, as well as popular online services such as Namecheap and Overstock. While Bitcoin remains a what does 2 confirmation mean bitcoin new phenomenon, it is growing fast.

As of Maythe total value of all existing bitcoins exceeded billion US dollars, with millions of dollars worth of bitcoins exchanged daily. While it may be possible bitcoun find individuals who wish to sell bitcoins in exchange for a credit card or PayPal payment, most exchanges do not allow funding via bitclin payment methods. This is due to cases where someone buys bitcoins with PayPal, and then reverses their half of the transaction.

Payments are made from a wallet application, either on your computer or smartphone, by entering the recipient's address, the payment amount, and pressing send. To make it easier to enter a recipient's address, many wallets can obtain the address by scanning a QR code or touching two phones together with NFC technology.

Much of the trust in Bitcoin comes from the fact that it requires no trust at all. Bitcoin is fully open-source and decentralized. This means that anyone has access to the entire source code at any time. Any developer in the world can therefore verify exactly how Bitcoin works.

All transactions and bitcoins issued into existence can be transparently consulted in real-time by. All payments can be made without reliance on a third party and the whole system is protected by heavily peer-reviewed cryptographic algorithms like those used for online banking.

No organization or individual can control Bitcoin, and the network remains secure even if not all of its users can be trusted. You should never expect to get rich with Bitcoin bjtcoin any emerging technology.

Nitcoin is always important to be wary of anything that sounds too good to be true or disobeys basic economic rules. Bitcoin is a growing space of innovation and there are business opportunities that also include risks.

Bitcoins can also be exchanged in physical form such as the Denarium coinsbut paying with a mobile phone usually remains more convenient.

Bitcoin balances are stored in a large distributed network, and they cannot be fraudulently altered by anybody. In other words, Bitcoin users have exclusive control over their funds and bitcoins cannot vanish just because they are virtual. Bitcoin is designed to allow its users to send and receive payments with an acceptable level of privacy as well as any other form of money.

What does 2 confirmation mean bitcoin, Bitcoin is not anonymous bitconi cannot offer the same level of privacy as cash.

The use of Bitcoin leaves extensive public confimration. Various mechanisms exist to protect users' privacy, and more are in development. However, there is still work to be done before these features are used correctly by most Bitcoin users.

Some concerns have been raised that private transactions could be used for illegal purposes with Bitcoin. However, it is worth noting that Bitcoin will undoubtedly be subjected to similar regulations that are already in place inside existing financial systems.

Bitcoin cannot be more anonymous than cash and it is not likely to prevent criminal investigations from being conducted. Additionally, Bitcoin is also designed to prevent a bktcoin range of financial crimes. When a user loses convirmation wallet, it has the effect of removing money out of circulation. Lost bitcoins still remain in the block chain just like any other bitcoins.

However, lost bitcoins remain dormant forever because there is no way for anybody to find the private key s that would allow them to be spent. Because of the law of supply and demand, when fewer bitcoins are available, the ones that are left will be in higher demand and increase in value to compensate.

The Bitcoin network can already process a much higher number of transactions per second than it does today. It is, however, not entirely ready to scale to the level eman major credit card networks. Work is underway http://trackmyurl.biz/bitcoin-investment-trade-1629.html lift current limitations, and future requirements are well known.

Since inception, dors aspect of the Bitcoin network has been in a continuous process of maturation, optimization, and specialization, and it should be expected to remain that way for some years to come. As traffic grows, more Bitcoin users may use lightweight clients, and full network nodes may become dhat more specialized service. For more details, see the Scalability page on the Wiki. To the best of our knowledge, Bitcoin has not been confirmaion illegal by legislation in most jurisdictions.

However, some jurisdictions such as Argentina and Russia severely restrict or ban foreign currencies. Other jurisdictions such as Thailand may limit the licensing of certain entities such as Bitcoin exchanges.

Regulators from various jurisdictions are taking steps to whaat individuals and businesses with rules on how to integrate this new technology with the formal, regulated financial. Bitcoin is money, and money has always been used wjat for legal and illegal purposes. Cash, credit cards and current banking systems widely surpass Bitcoin what does 2 confirmation mean bitcoin terms of their use to finance crime.

However, these features already exist with cash and wire transfer, which are widely used and well-established. The use of Bitcoin will undoubtedly be subjected to similar regulations that are already in place inside existing financial systems, and Bitcoin is not likely to prevent criminal investigations from being conducted.

In general, it is common for important breakthroughs to be perceived as being what does 2 confirmation mean bitcoin before their benefits are well understood. The Internet is a good example among confirmqtion others to illustrate. The Bitcoin protocol itself cannot be modified without the cooperation of nearly all its users, who choose what software they use.

Attempting to assign special rights to a local authority in the rules of the global Bitcoin network is not a practical possibility. Any rich organization could choose to invest in mining hardware to control half of the computing power of doee network and become able to block or reverse recent transactions. However, there is no guarantee that they could retain this power since this requires to invest as much than all other miners in confirmattion world.

It is however possible to regulate the use of Waht in a similar way to any other instrument. Just like the dollar, Bitcoin can be used for a wide variety of purposes, some of which can be considered wha or not as per each jurisdiction's laws.
