In this case, clearly the coins have not been transferred. This is roughly like a tree falling in the forest with nobody around to hear it. However, sending the signed statement only to Bob is not enough, because Alice could have signed a conflicting transaction saying she wants to transfer the coins to Carol which she only sends to Carol.
If Bob and Carol both accepted these statements as indicating that they have received the coins from Alice, then Alice will have effectively spent her coins twice! This is where the idea of a global ledger comes in. If Alice wants to transfer her coins to Bob, she must publish her statement authorizing the transfer to the blockchain. The miners who maintain the blockchain will only include this transaction if Alice has not yet transferred the coins to anybody else, so once Bob sees the transaction appear in the blockchain he can be confident that he is the new owner.
Even if Alice later tries to produce a statement saying she transfered the coins to Carol, it will never be accepted into the blockchain because the transaction transferring to Bob was published first. Unfortunately, the blockchain does not offer strong consistency , meaning that any data included in the blockchain is guaranteed to be included forever.
For technical reasons, the blockchain offers a weaker property called eventual consistency , meaning that eventually all parties will agree on the blockchain up to a certain ever-increasing prefix. Put another way, the blockchain is a series of n blocks currently almost , , and at any given time the most recent several blocks are not guaranteed to be permanently included.
It is possible for the blockchain to fork by having multiple potential often inconsistent blocks which claim to be the last block in the chain. When an apparently valid block is replaced by a competing block, this is called a blockchain reorganization and the replaced block is called an orphan block.
However, it is possible although rare for the last n blocks to be orphaned in a reorganization. This is exponentially less likely to occur the larger n gets. It typically happens multiple times a day, for example, that a single block is orphaned, but has happened only a few dozen times in history for n between 2 and 4, and exactly once for n greater than 4 a block reorganization in March due to a technical glitch. Barring technical glitches, formal modeling of Bitcoin suggests that large reorganizations are exponentially unlikely, but possible.
In practice, the community has adopted 6 blocks as a standard confirmation period. For relatively small transactions like buying coffee , users might be fine with a shorter confirmation period such as one or even zero blocks. Assuming Alice is fine with the community standard of 6 blocks, how long will she have to wait?
Because blocks are found by a random process, there is no telling precisely how long it will take for 6 blocks to be found. On average, it takes about 10 minutes to find each block. The average block time can actually be slightly shorter or longer depending on if the total hash power of the Bitcoin network is growing or shrinking. Ignoring this detail though, this is why 6 confirmations take about 1 hour on average. However, the block-creation or mining process is random and each block may take much longer or shorter.
At a high level, a transaction is confirmed when it is permanently included in the Bitcoin blockchain. Unfortunately for Dave, this process does not occur instantaneously. In fact, bitcoin transactions are subject to delays ranging from a few minutes to a few days. This is because bitcoin requires miners to verify transactions.
However, due to its rising popularity, the bitcoin network is often backlogged with transactions waiting to be lumped into a block. For an idea of the backlog, check out the current Bitcoin Mempool. Mining requires significant effort and technology, so bitcoin transactions are increasingly subject to additional fees. A Satoshi is one hundred millionth of a bitcoin, per byte size of the transaction, which is usually over bytes. Transaction fees are usually set by the user creating the block of transaction data to be mined.
These rates and their dependent wait times vary as traffic ebbs and flows. For instance, you could pay satoshis per byte which is 0. Your transaction will thus take about minutes to be verified. Alternatively, you could pay a higher fee—say, satoshis per byte—to have your transaction placed in the immediate queue or the next block to be mined.
Your transaction will likely be completed in the next 10 minutes. Bitcoin is a user-based, peer-to-peer system, thus making the system prone to volatility and experimentation. As of this writing, Bitcoin transactions had become alarmingly expensive—at one point, for example, moving 0.
As bitcoin continues to develop as a platform, the roller coaster of rates, fees, and wait times will likely stabilize. Time will tell if the continued use of bitcoin will smooth out the frequently uneven transaction process. Hodlnaut vs. Voyager Invest is a comparison worth making.
While the mainstream has yet to…. How Long do Bitcoin Transactions Take? Steven Buchko. How long does it take to confirm a Bitcoin transaction? Bitcoin transaction times vary and can take anywhere from 10 minutes to over 1 day. What determines Bitcoin transaction times? What is the average Bitcoin transaction time? The average Bitcoin transaction time is currently around 1 hour. What determines the Bitcoin transaction times? The two main factors influencing the transaction time are: The amount of network activity Transaction fees The more transactions that the network needs to process, the longer each transaction takes.
Only time will tell which solution proves to be the best. What is a bitcoin transaction? How does a transaction work? This code explains the history of how the bitcoins came to your public key. Amount: the number of bitcoins—in this case, five—that you intend to send to Dave.
