I want to check for every transaction if there is enough balance to pay it(including fee). I found this question: Is there a way to know the Bitcoin Network transaction fee BEFORE actually submitting the transaction?
But what do I have to use as the TXID by createrawtransaction?
I am working in an artistic/visualization project that analyses Bitcoin transactions. I have a
Bitcore instance with insight API and from a Python script I query through the REST API so the queries are returned in json format. For the project I use a macbook pro and with its internal ssd drive I get around 70 queries per second, using an external NTFS (fuse drivers) driver I get as little as 5 per second.
I would like to know if there is a faster way to query transactions by transaction’s hash even if it is more complex to code.
What would be the fastest way to query for a certain txid to get its inputs?
I want to get how long it takes time to get first confirmation for each transactions.
My plan is this below.
- I’m subscribing mempool txes notification from my bitcoind node and I will save it with time.
- I receive a block generate notification which contains the saved mempool-tx. Then I will calculate the confirmation time. (confirmation time = mempool save time – block notification time)
This is a little bit hassle. It would be easy if I can get the time by txid. Is it possible? or Do you have any better ideas?
A lot of people have requested a list of addresses and transactions related to the theft. I believe there are already lists out there as several people have sent me some, but here is an official one:
