#SayNoToEmptyBlocks

An inntiative to stresstest TX/Block using one address and sequence

This should only be installed on a fullnode not a validator, as it exposes your key in plaintext

1. Install Expect

sudo apt-get install expect

sudo apt-get install expect-dev

2. Clone this wonderful repo!

git clone https://github.com/mohammedpatla/SayNoToEmptyBlocks

cd /SayNoToEmptyBlocks

3. Modify send.sh with your fullnodes key-alias & the account your sending transactions to (This is your indivdual send TX that will run in SEQ)

Make sure to fund your fullnode's account with some SCRT first !

Note that this will be used by expect to create a sequence of TX.

nano send.sh

4. Add your password in singmultiple.exp and verifysing.exp

Replace "<-password->\r" with your Key-ring password.

nano signmultipl.exp
nano verifysingle.exp

You can see using cat signmultipl.exp that it stores your key-alias password in plaintext >=\

5. Now get your sequence number as you will need it in the following commands , run:

secretcli q account <-Account-Address->

6. Now we run the loop to sign all the trasnactions, this be fefault does 300 TX, but you can change it by changing the for loop in loopmultiple.sh

./loopmultiple.sh <sequence-id>

7 (optional)Verify all your signed transactions

./verifysingle.sh <sequence-id>

8 Now we need to do some manual editing

Go to file signedSendTx.json and change the formating of the file. The JSON file looks like this

  {
    tx1
  },
  {
    tx2
  },
  

You need to change it to this format

[
 {
   tx1
 },
 {
   tx2
 }
]

9 Now we compress the above file into propr format

jq -c '.[]' signedSendTx.json  > formatjson.json

10 If all the above steps went good then Your JSON file formatjson.json should look something like this

{tx1}
{tx2}

11 Now running the TX to the Node

./multtx.sh <sequence-id>

This will run a loop showing an ouput log of running TXs

Limitations

You may see that at some point in your loop of sending TX's your node will return Unotharized sign with code:19

That is because your loop is running extremly fast and before the node registers TX1 the next SEQ of TX2 was submiited, breaking the Sequence. I was only able to get upto 50TX in a block.
