Understanding Ethereum Raw Transactions Using JSON
As a cryptography and blockchain enthusiast, it is essential to understand the inner workings of Bitcoin transactions, especially when it comes to raw data structures. In this article, we will delve into the details of Bitcoin’s raw transaction format, with a particular focus on its JSON representation.
Bitcoin Transaction Structure
Bitcoin transactions are made up of various components, including:
- Transaction ID: A unique identifier for the transaction.
- Type: The type of transaction (e.g., send, receive, split).
- From
: The sender’s address.
- To: The recipient’s address.
- Value: The amount being transferred.
- nonce: A random number used to verify the validity of the transaction and ensure that it has not been tampered with.
- locktime: The block timestamp when the transaction is locked (i.e. not yet confirmed).
- sequence: An integer that increments for each transaction in the batch.
JSON Representation of a Bitcoin Transaction
The JSON representation of a Bitcoin transaction looks like this:
{
"txid": "1...", // transaction ID
"type": "send", // type (e.g. send)
"from": {
"addr": "...", // sender address
"key": "...", // sender's public key
"pubkey": "...", // sender's public key hash
},
"to": {
"addr": "...", // recipient address
"key": "...", // receiver's public key
"pubkey": "...", // recipient's public key hash,
},
"value": {
"amount": 1.00, // transaction amount in satoshis (e.g. 1 BTC)
"unit": "satoshis" // transaction amount unit
},
"nonce": 1, // random number used to verify the transaction validity
"locktime": 1500, // lock timestamp when the transaction is locked
"sequence": 100, // increments for each transaction in the batch,
}
In this example, we have six main properties:
- “txid”: transaction ID.
- “type”: transaction type (in this case “send”).
- “from” and “to”: sender and recipient addresses, respectively. Note that these are arrays containing individual address objects.
- “value”: transaction amount in satoshis (e.g. 1 BTC) along with its unit (in this example “satoshis”).
- “nonce”, “locktime”, and “sequence”: these properties are used to verify the validity of the transaction and ensure that it has not been tampered with.
Conclusion
To understand the inner workings of the blockchain, it is essential to understand raw Bitcoin transactions using JSON format. By analyzing the structure of a particular transaction, we can gain insights into the data exchanged between parties on the network. In this article, we have provided an overview of the JSON representation of Bitcoin transactions and shown how to analyze these structures.
