nano-mass-tx

With all the talk of Nano Currency network stress testing, there should be a simple tool to take part yourself. This is that tool.

Installation and Usage

Use nvm to install Node.js if you do not already have it installed. Install the package globally:

$ npm install -g nano-mass-tx

As shown below, you will be prompted for the parameters of the process. You may exit with Ctrl+C or Ctrl+D (at prompts) at any time and resume progress by speciying the same output file.

If for some reason your balance is not returned at the end of the sequence, you may import the seed from the output file into a wallet and recover the funds.

Start the process, specifying an output file that will be saved to each at update or resumed from in later instances:

$ nano-mass-tx test.json
error reading persistence file, starting from new

A wallet with 2 accounts is generated randomly at the beginning. The test will transfer the balance of one account to the other and back again until the number of transactions desired has been reached. The first prompt asks how many transactions to send.

How many transactions to send? (not counting the final return transaction, will be rounded to nearest odd number greater than or equal to 3) 10

You are then prompted to send an amount to the first account.

Please specify 64 character hex string of a pending send block to xrb_1dnukwcqaq93ni8qaqjsrcrgmobhfozzroj8yukfkkc737tdkbsar1s68odd

Perform this transaction with an external wallet before continuing.
What is the hash of the block? 6EC4A09C2F64911CEF91A4A271E8268D883D09663ED070E9613ACF53917781F3

Next, the work is calculated for each block using the raiblocks-pow native code NPM module.

Finally, a prompt for the return address is asked, the last work value is calculated, and then the messages are sent to the network of nodes.
