What Is A Cryptocurrency Transaction And How Does It Work?

Sending and receiving cryptocurrency is something that even a beginner can do successfully due to simple-to-use wallets. But do you really know what a crypto transaction is? If you struggle to answer this question, this article is for you.

What Is A Crypto Transaction?

In simple words, a cryptocurrency transaction is a transfer of funds between crypto wallets that gets inscribed to the blockchain the currency operates on. Sometimes people also call transactions TXNS, which is short for transactions. As you probably already know, cryptocurrency doesn’t actually belong to a user the same way fiat does — it actually “lives” on the blockchain and never leaves it. That means that the transferring of the crypto works differently too, making the process more complex to understand than the simple fiat transaction we’re all used to.

How Does A Crypto Transaction Work?

So how does the crypto transfer work? Let’s break it down into more detail.

Stage 1: Initiation of the transaction

A crypto transaction involves three important parts: sender, receiver and transaction details. Sender is the one who creates a request to send a certain amount of crypto to another user. Receiver is the one who provides the sender with their wallet address to get the assets. Transaction details include the amount of crypto to be sent and the addresses of participants’ wallets. If you have all of the above on you, you’re ready to proceed with the transaction.

Stage 2: Verification and authorization

After entering all the needed details, the sender signs the transaction using their private key — an alphanumeric code that permits access to the cryptocurrency holdings. It’s an essential cryptographic step that proves that the sender owns the cryptocurrency they’re trying to send. The private key generates a digital signature, which is used to confirm the sender’s identity and authorize the transaction. But in most cases you don’t need to always remember your private key: if you’re using a custodial wallet, such as Cryptomus, the wallet provider signs the transaction with your private key automatically.

Stage 3: Broadcasting the transaction

Once signed, the transaction is broadcast to the network, specifically the nodes — computers running the cryptocurrency protocol. All crypto transfers are recorded on the blockchain, which acts as a public ledger for them.

Stage 4: Transaction validation

The transaction has to be validated, whether by miners using the PoW algorithm or by validators using the PoS algorithm; they should confirm the transaction’s legitimacy. This process involves verifying that the sender has enough cryptocurrency to make the transaction and ensuring that there are no double-spending issues. In this regard, the transaction does not take place immediately, and it takes time for it to take place. This stage also includes a network commission, the amount of which often determines the speed of the transfer.

Once validated, the transaction is grouped with other transactions into a block, which is then added to the blockchain.

Stage 5: Completion

Once the transaction is recorded in the blockchain, it’s considered “confirmed”, and the recipient can now see the funds in their wallet.

Elements Of Crypto Transactions

Now that we understand how crypto transactions work, let’s dive a bit more into all the elements of which such a transfer consists. Why is it important? Understanding each of these components is key to grasping what and how makes the movements of your funds fast, secure, and anonymous.

Wallet Address

A wallet address is a unique string of characters that functions as the destination for cryptocurrency transfers. Think of it as a digital account number. Each wallet has a public address and a private key:

• Public address is a unique number that the recipient gives to the sender. It’s used to receive cryptocurrency, and it’s safe to share publicly.
• Private key is used to sign transactions and verify ownership of the cryptocurrency associated with the wallet. It's a sensitive piece of information that has to be kept secure.

When you send cryptocurrency, you input the recipient's public wallet address. The transaction will be validated using this address to ensure it is routed correctly.

Hash

A transaction hash, often referred to as a TxHash, is a unique signifier generated whenever a transaction is executed within a blockchain system. Once it's confirmed, the transaction ID (TxHash) becomes fixed, making sure the record of the transaction is valid and unchangeable. It includes essential information about the transaction, like the digital wallet addresses involved, the amount transferred, and the exact date and time, along with its current status. This allows to track every stage the transaction goes through using blockchain explorers.

It's important to know that these transaction IDs are unique to their blockchain, which means their format may vary from network to network, like Bitcoin and Ethereum.

Fees

Cryptocurrency transactions require a transaction commission, which is paid to the miners or validators who process and confirm the transaction. These fees serve several purposes:

• Incentive for miners/validators: fees reward the miners (Proof-of-Work mechanism) or validators (Proof-of-Stake mechanism) for dedicating computing power or stake to validate and add transactions to the blockchain.
• Transaction prioritization: in some networks, fees can influence the speed at which a transaction is processed. Higher commissions often encourage miners to prioritize the transaction, speeding up confirmation times.

Transaction fees can vary depending on the blockchain network’s congestion. For example, during times of high activity, the fees on the Ethereum network can rise to incentivize quicker processing.

Confirmation

Once a transaction has been initiated and broadcast to the network, it must be confirmed before it is fully processed. Confirmation refers to the process by which miners or validators verify that a transaction is legitimate and add it to the blockchain.

Every crypto transaction needs multiple confirmations so it seems fitting to discuss their types:

• Initial confirmation: once a miner validates a transaction and includes it in a block, the transaction receives its first confirmation.
• Additional confirmations: after the block is added to the blockchain, subsequent blocks are linked to it, providing more confirmations. Typically, more confirmations mean the transaction is less likely to be reversed.
• Finality: in most cryptocurrency networks, after 6 confirmations, a transaction is considered irreversible and fully confirmed. However, some networks may require fewer or more confirmations for finality, depending on their security model.

The confirmation process ensures that the blockchain remains secure, as it requires affirmation from multiple parties before the transaction is deemed valid.

These core elements — wallet address, hash, fees, and confirmations, ensure the integrity, security, and reliability of cryptocurrency transactions, forming the backbone of the decentralized networks that power digital currencies.
