Dans l'univers du Bitcoin, une confirmation signifie qu'une transaction a été ajoutée à un bloc. Ces confirmations se produisent environ toutes les 10 minutes, marquant ainsi la finalisation d'une transaction. Une fois ajoutée à un bloc, la transaction est considérée comme réglée.
Qu'est-ce que les Confirmations ?
Roughly every ten minutes, a new block is created and added to the blockchain through the mining process. This block verifies and records any new transactions. The transactions are then said to have been confirmed by the Bitcoin network.
Combien de Confirmations sont Suffisantes ?
Le nombre de confirmations nécessaires dépend de la nature de la transaction. Une confirmation est suffisante pour les petit* paiements Bitcoin, tandis que les paiements plus importants peuvent nécessiter jusqu'à six confirmations pour être considérés comme sécurisés.
1 Confirmation : Suffisante pour les paiements inférieurs à 1 000 $.
3 Confirmations : Nécessaires pour les paiements de 1 000 $ à 10 000 $. La plupart des plateformes exigent 3 confirmations pour les dépôts.
6 Confirmations : Standard pour les paiements importants entre 10 000 $ et 1 000 000 $.
60 Confirmations : Suggérées pour les paiements dépassant 1 000 000 $.
Comment Vérifier les Confirmations Bitcoin
Une fois votre transaction effectuée, votre portefeuille devrait vous offrir la possibilité de consulter la transaction sur un explorateur de blocs ou de vous fournir l'ID de transaction. Utilisez des explorateurs tels que blockstream.info pour vérifier le nombre de confirmations.
Le graphique ci-dessous illustre le temps moyen nécessaire aux mineurs pour trouver un bloc, chaque bloc trouvé équivalant à une confirmation. Bien que la blockchain Bitcoin vise des blocs de 10 minutes, des variations surviennent en raison de changements majeurs dans le taux de hachage du réseau.

Foire Aux Questions (FAQ)
Si Votre Transaction Bitcoin Est Non Confirmée
Si votre transaction reste non confirmée pendant des heures, la patience est de mise. Attendez au moins 72 heures avant de considérer des mesures alternatives, telles que la retransmission de la transaction.
Combien de Confirmations Coinbase Nécessite-t-elle ?
Coinbase exige trois confirmations avant qu'une transaction n'apparaisse et ne soit dépensable sur votre compte Coinbase.
Est-il Possible qu'une Transaction se Confirme en Moins de 10 Minutes ?
Oui, plusieurs facteurs peuvent accélérer la confirmation, notamment des ajustements inappropriés de la difficulté, une soudaine augmentation de la puissance de hachage, ou simplement la chance du mineur.
Comment Accélérer les Confirmations ?
Bien qu'il ne soit pas possible d'accélérer le rythme d'ajout de blocs à la blockchain, augmenter les frais de transaction peut accroître la probabilité d'inclusion dans le prochain bloc.
SegWit Diminue-t-elle les Temps de Confirmation ?
Techniquement non, mais SegWit rend les transactions moins coûteuses en raison de leur taille réduite. Cela permet d'allouer les économies réalisées pour augmenter les frais, augmentant ainsi les chances d'une inclusion rapide dans un bloc.
Solutions aux Transactions Bloquées
En cas de transaction bloquée, des solutions telles que les transactions de remplacement (RBF) ou les transactions enfant-payent-pour-les-parents (CPFP) peuvent être envisagées. Les portefeuilles matériels comme Ledger Nano X, avec l'utilisation de Ledger Live, offrent également des options pour résoudre les transactions bloquées.
Conclusion
Comprendre le processus de confirmation Bitcoin est crucial pour garantir la sécurité des transactions. La patience est la clé en cas de retard, mais des options existent pour résoudre les problèmes potentiels. Utilisez ces connaissances pour optimiser vos transactions Bitcoin et assurer une expérience fluide.
Bitcoin is the public blockchain used to create and manage the cryptocurrency of the same name. Bitcoin mining is the race between miners to hash specific values and other block information to find the solution to a hashing problem and add a block to the blockchain. The winning miner is rewarded with bitcoins.
Different cryptocurrencies require different numbers of confirmations before a transaction is considered final. For example, a Bitcoin transaction is often considered secure after six confirmations, while Ethereum transactions are usually considered secure after around 30 confirmations.
(What are bitcoin miner fees?) If your transaction has not been confirmed yet, please allow some time for it to be confirmed. Typically, a transaction takes between five minutes and three hours to get confirmed. This is normal, and confirmation time depends mostly on current network traffic.
The easiest way to do this is to use a Bitcoin wallet that supports the RBF (replace by fee) feature. RBF allows you to replace an unconfirmed transaction with another transaction with a higher associated fee.
Summary: As of 2024, there are about 420 million cryptocurrency users globally. Of these, approximately 1.5 million individuals possess more than 1 Bitcoin, which is just 0.36% of all cryptocurrency users.
A Bitcoin transaction needs 6 confirmations before it can be marked as complete. On average, it takes 10 minutes to mine a block (a mined block is the same as a confirmation). This is why it takes 60 minutes on average to send Bitcoin from one wallet address to another.
Bitcoin's blockchain can be accessed at https://blockchain.info/. Here, you'll be able to enter your Bitcoin TxID, or your exchange or wallet address, to track your transactions. You will see a summary of information about the transaction, including the number of confirmations it has.
Enter the transaction ID on the Bitcoin network that you wish to confirm more quickly. Click on the [Check] button to receive a cost estimation for speeding up that specific transaction. Tap on the [Pay to accelerate] button and complete payment to speed up the confirmation of your transaction on the Bitcoin network.
This can take anywhere from five minutes to an hour, depending on the Bitcoin network. However, some Bitcoin transactions can take longer to be confirmed by miners. If you believe your transaction is taking longer than usual to be confirmed it could be due to mempool congestion and fees.
By including an appropriate fee, you can enhance the priority of your transaction, leading to quicker confirmation. Conversely, if the fee is too low or absent, miners may choose not to validate the transaction, resulting in rejection.
If you set your Bitcoin Transaction Fee too low it can remain unconfirmed for days or even months. If the network is continuously busy – especially during bull markets – and the fee you set is lower than everyone else then it won't get confirmed until things cool down, but this can take a long time!
If your transaction has not been confirmed, it means that it is still waiting in the mempool, and it may take longer depending on the network congestion and the fee you paid.
If you are sure there was no mistake in the address then you need to check the transaction ID that you must have got when you transacted. You can check the transaction ID on BLOCKTRAIL | Bitcoin API and Block Explorer.Put in the transaction ID and it should show you the status of the number of confirmations.
Bitcoin is a form of digital currency that uses blockchain technology to support transactions between users on a decentralized network. New Bitcoins are created as part of the mining process, as a reward to people whose computer systems help validate transactions. Buying Bitcoin exposes you to a volatile asset class.
Mining Bitcoin. When Bitcoin transactions are completed—and a new block is added to the blockchain—a Bitcoin is 'minted' in a process known as mining. ...
Ultimately, investing in bitcoin is a personal decision, whether you're buying ETFs or actual digital coins. If you decide to invest, you should have an already diversified portfolio of assets like index funds. You typically don't want to invest money in speculative assets you can't afford to lose.
