kandi X-RAY | sendtx Summary

sendtx is a Python library typically used in Blockchain, Cryptocurrency, Bitcoin applications. sendtx has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can install using 'pip install sendtx' or download it from GitHub, PyPI.

Python module for sending bitcoin transaction directly to the bitcoin network. What: This module broadcast given bitcoin transaction into Bitcoin network using just P2P connection to some trusted Bitcoin node. Why: No bitcoind patches needed anymore.. How: Library creates two connections to the trusted node: One listen for new transactions on the network, second sends serialized transaction to the network. Trusted node make internal checks and if the transaction is valid, it accepts the transaction into it’s memory pool and rebroadcast it to connected peers… …so when our second (checking) connection sniff our txhash on the bitcoin network, we have a confirmation that the transaction has been succesfully accepted by the network. This library is built on top of ArtForz’s half node with some modifications for Twisted framework. For this reason I’m using the hack with subprocess module, so calling application don’t need to care about Twisted stuff. Commandline example: ./sendtx.py localhost 01000000015210999277896…0000000 Script returns exit code 42 on success. Python script example: #!/usr/bin/python import sendtx try: sendtx.process(localhost, 01000000015210999277896…0000000) except: print "Broadcast failed".

QUESTION

Web3 web3.eth.sendSignedTransaction Invalid params

Asked 2020-Apr-04 at 14:34

Im very new to ethereum i have set up a private network using the pantheon client. i have successfully deployed a contract to the network and all interactions with the contract work when using through remix.

I am trying to set up a relay where a transaction is signed client side, sent to a nodeJs server and then the server proxies the transaction to the contract. however when i pass the signed transaction to sendSignedTransaction() i get the error Invalid params, to me this is very vague and i am unsure what i'm doing wrong / what the invalid params are. (any advice on how to debug this?)

UPDATE

using web3 v1.2.0

After a lot of trail and error an 0 suggestions on stack overflow working, i have got the transaction signing working!. In the end i came away from using ethereumjs-tx (which for some reason is recommended by a lot of people) and used just pure Web3.

QUESTION

BluetoothGatt.writeCharacteristic return false half the time

Asked 2018-Nov-12 at 19:14

Actually I make an update through Bluetooth. In first time I erase the memory bank and then I write an hexa File on it.

But half the time an update will don't work correctly, for every data I transfer the first writeCharacteristic will return false. It happen on an entire update half the time.

I try in debug mode but the method never return false in that case, of course it's probably a delay problem, but I can't increase the time.

This is my code for send my data :

Never use timeouts to try to workaround this issue. The proper way is to wait for the callback and then perform the next request. See Android BLE BluetoothGatt.writeDescriptor() return sometimes false.

To control whether timing information is output in instructions.go, yes you could add a boolean variable to the file instructions.go (perhaps something like):
