Coinbase managed to support its clients save 75.2 percent in fees of transactions and decreasing their regular transaction count by 95 percent by the method of Bitcoin batching transactions. Transaction batching mainly implies mixing multiple transactions into one rather than formulating a new transaction for each request. It dramatically decreases the cost of transacting BTC and also decreases the overall network load of BTC, enabling it to fit more in little places.
Presently, many famous Bitcoin exchanges utilize this scaling technique of payment batching. Several wallets have it as a built-in character that users can instantly implement in payment-sending solutions and custom wallets. This article will introduce Bitcoin batching transactions, some advantages it has on its users, and also a relatable disadvantage.
What is Bitcoin Batching?
Unlike other digital currencies such as Ethereum or Ripple using an account or balance model, BTC uses another alternative known as the UTXO model (Unspent Transaction Output) – in its transactions. Bitcoin users do not have balances in their wallets; instead of that, they have UTXOs that they control.
When transacting BTC to someone else, the sum they are required to transfer should be equal to the number of UTXOs their wallet chooses as inputs. The recipient will get the desired amount (output), after which the sender receives the difference and the change output. The output comprises an unlimited number of BTC in Satoshi which is the lowest denominational unit of a Bitcoin (1 Satoshi equals 0.00000001 Bitcoin).
An Easy Example Of Bitcoin Batching Transactions
If you are purchasing a soda for $10 and only have $20, you do not give the cashier half of your 20 dollar bill, you give him the 20 and get some change instead.
A block has no hardcoded restriction on the number of transactions it can fit. Therefore, since miners have restricted space of 2MB to sell, they will be required to pay higher fees for more prominent transactions to be included.
There are two strategies in which you can keep your transactions as little as possible and save charges:
- UTXO consolidation or consolidating your outputs – Here you can use as few inputs as possible by constantly sending smaller UTXOs to yourself when the charges are low and get one large UTXO back
- Transaction batching – if you have made frequent transfers, you can involve an almost unlimited quantity of outputs to varied people in one transaction
Batching is common in the case of mining pools or exchanges that can trade off immediately for efficiency. A batched transaction from any exchange will have dozens if not hundreds of results; hence, it is rare for an everyday BTC owner to go to the added effort of batching transactions. Along with that, most wallets make it difficult to build batched transactions
Advantages Of Batching Bitcoin Transactions
Now that you have got some idea about Bitcoin batching transactions, let us have a look at its advantages.
The Ideal Way To Gather Multiple Transfers
Batching is a great way to decrease the number of transactions by aggregating numerous single transfers. Before batching, BTC users would send transactions with a unique transaction ID for each of them.
Decreasing The Maximum Amount Of Unspent Bitcoin In Your Wallet
Batching transactions formulates a single change output for all the transaction payments, which leads to fewer unused inputs in your wallets like the Coinbase wallet.
Minimized Consumer Transaction Fees
The fees for sending several transactions prominently decrease when batching Bitcoin transactions as they merge into one. This is known as the reflection fee. So if you are wondering what is reflection fee in crypto, it applies a 1 percent fee to RFI transactions that are mechanically distributed among coin holders. The amount depends on the size of every investors’ position.
Reduced Transaction Generated Each Day
Bitcoin batching transactions minimize transactions made each day, which implies our services are doing fewer operations to attain the same outcome. Less block space is required with batched transactions, decreasing the overall effect on the network, and you can be more effective.
Decreased Internal Alerts For Exchanges
Exchanges constantly monitor their systems and they also alert engineers when services begin operating outside the norm. Before Bitcoin batching transactions, the time it took for a BTC to send a request to get processed and then submitted to the network as a transaction was highly delayed.
Disadvantages Of Bitcoin Batching Transactions
Every coin has two ideas and so do the batching transactions in Bitcoin. So now that you know its benefits, let us look at the drawbacks of the same.
The prominent benefits of batching are decreased fees and lower costs; however, it also comes with disadvantages which are a lack of centralization and privacy. After you send users using a similar transaction, they can assume that you pay everyone else getting an output from that transaction. Nevertheless, this issue is partially avoidable by sending batched payments in a coinjoin transaction formed with other users.
Many crypto exchanges make payments to users when those users make any withdrawal request. But when it is about batching, users are required to accept that their payment will not be sent instantly, only after some time when it mixes with other withdrawal requests. Initially, there will be a delay in notifying the users in their receiving wallet of the transaction that is unconfirmed unless they send the batch that contains their payment. Secondly, by delaying the transactions of their payment, there will be a delay in its confirmation.
The Bottom Line
Bitcoin batching transactions is one efficient way to decrease costs and fees; however, one last issue is that users are unable to fee bump a batched payment. To safeguard attackers from wasting node resources, transaction relay nodes like Bitcoin Core impose restrictions on the transactions. The receiver of your payments can reply to their output in lesser transactions that create the transaction group that has your transaction. There is also Ethereum transaction batching that works the same as Bitcoin.
