Here is an article that explains the meaning of error code “-26” in the context of Bitcoin:
Understanding Error Code -26: A Guide to Bitcoin Transactions
In Bitcoin, transactions are processed by a network of computers called nodes. These nodes verify and validate the transaction data, ensuring that the sender has the necessary funds and that the recipient is willing to accept the transfer. One common error in this process occurs when a transaction is sent to a blockchain node, including the “sendrawtransaction” RPC (Remote Procedure Call) method.
In your case, you are experiencing an error code -26 while broadcasting a transaction on the testnet ( Let’s figure out what this error message means:
What does -26 mean?
Error code -26 usually means that the node is not in a “final” state. Bitcoin nodes are considered final when they have received all the necessary data from other nodes and can complete their transaction verification process.
How does the sendrawtransaction method work?
When you use the sendrawtransaction RPC method to broadcast a transaction on the testnet, it sends the transaction data over the network. However, if the node is not in a final state (i.e. it is still receiving or processing other transactions), an error -26 will occur.
What does this error mean?
The sendrawtransaction RPC method returns an error (-26) when the node is not in a final state because the transaction data has not been fully confirmed and verified by all nodes in the network. This can happen for a variety of reasons, such as:
- Insufficient funds: If you have not received enough funds from other nodes to cover the transaction fees.
- Missing or incomplete information
: If your transaction has missing or incomplete fields, such as signature verification, or if it does not comply with the Testnet rules and regulations.
- Network congestion or overload: If there is a lot of activity on the network, causing the node to be overloaded or overloaded.
What can you do?
To resolve this error, you need to ensure that the transaction details are fully validated and confirmed by all nodes on the testnet. Here are some steps you can take:
- Verify your funds: Check that you have enough funds to cover the transaction fees.
- Fill in missing fields: Make sure that the transaction details contain all required fields, such as signature verification.
- Follow Testnet rules and regulations: Familiarize yourself with the Testnet rules and regulations to avoid problems when performing transactions.
After following these steps, you should be able to resolve the error -26 and successfully broadcast the transaction on the testnet. If you are still experiencing problems or have more questions, feel free to ask!
