Blockchain

What blockchain is

Blockchain is a digital record book shared across computers, called nodes. It groups transactions into blocks that link to earlier blocks. Network participants check whether transactions are valid before they are recorded, creating a shared history that is designed to resist alteration.

A blockchain is a type of distributed ledger. It is not the same thing as cryptocurrency: a business can use blockchain for recordkeeping without accepting digital currency. When you accept a blockchain payment, the customer sends a digital asset from a wallet to your business's wallet, and the transaction is recorded on the ledger.

Blockchain can bypass card fees, but network charges and irreversible transfers still put costs and risk on your business.

How a blockchain payment works

A customer initiates a transfer to your wallet address. Network nodes check the transaction, including whether the sender has funds and has not already spent them. After network confirmation, the ledger records the transfer and your wallet reflects the received asset.

Public blockchains operate around the clock, including weekends and holidays. Confirmation can take seconds or minutes, depending on the network and its conditions. This differs from card payments, which move through a card network and financial institutions before your business receives funds.

What it means for your costs and risk

A blockchain payment is not a card transaction, so it does not incur card interchange or card-network assessment fees. A direct wallet transfer can avoid some payment intermediaries, but the blockchain network can charge a transaction fee. A payment provider that handles acceptance or conversion can also charge for its services. There is no single blockchain fee schedule or guaranteed saving.

The asset's value matters too. If you accept cryptocurrency rather than a fiat-pegged stablecoin, its dollar value can change before you convert it. For example, an illustrative $100 payment could be worth $95 or $105 at conversion. Stablecoins are designed to track a fiat currency, but depegs and liquidity problems remain possible.

Confirmed blockchain transfers are practically irreversible, so a mistaken wallet address or token type can cause a loss without the usual card-dispute route. This reduces chargeback exposure for that payment, but also leaves you with less recourse for customer error or fraud. Wallet security and clear payment instructions are essential.

What you can actually change

Blockchain does not automatically lower your payment costs. Before accepting a digital asset, compare the network fee, any provider charge, conversion terms and the process for handling a mistaken or disputed payment.

• Compare the total network and provider charges with your current payment method.
• Choose whether to accept a fiat-pegged stablecoin or a price-volatile cryptocurrency.
• Set clear wallet, token and payment instructions, and secure access to the wallet.
• Decide whether to convert receipts to dollars promptly or hold the digital asset.

1. 01
   Price the full route. List network, acceptance and conversion charges before comparing a blockchain payment with cards or bank transfers.
2. 02
   Set a conversion policy. Choose how quickly your business converts digital assets to dollars and who can access the wallet.
3. 03
   Test the payment flow. Document how customers select the correct network and token, and how staff confirm receipt before fulfilling an order.
