About

Use Loggeru to automatically record file alterations to the Bitcoin SV blockchain.

Future features include CSV export, USD billing, Splunk integration, CLI decryption, and a visual explorer on loggeru.com.

Install

npm install -S bsv

npm install -g loggeru

Run

loggeru

This will return a BSV private key, public key, and address, as well as a AES 256 key. Please record these or use your own. We do not store these.

Once you have a funded BSV private key:

loggeru -k bsvPrivateKey -f /file/to/watch -t tagForYourData -r regexExpressionToLookFor -e optionalEncryptionCode

Example values:

  • -t myCompanyName
  • -f /var/log/secure
  • -k 36a5a9a7b2ef8d18538db2f16752dd015140d7e5e706aa0a364d17c92416b901
  • -r 'Accepted publickey'
  • -e fd2f50f13c7bcb424e68f04af14d515cbd42e637da9ed317338e4d35de564c5e`

This example checks /var/log/secure for new lines with 'Accepted publickey' in the text, then makes a BSV transaction with that data in the OP_RETURN.

The result of this is that the IP of anyone who accesses this RHEL/Centos virtual machine (Amazon Linux AMI) via SSH will be written to BSV.

Troubleshooting

Getting a permission error? For /var/log/secure on an Amazon EC2 instance, I fixed it with this:

sudo setfacl -Rm u:ec2-user:rX,d:u:ec2-user:rX /var/log

And also added this to /etc/logrotate.d/Loggeru_ACLs (otherwise permissions will be reset automatically):

{
  postrotate
    /usr/bin/setfacl -Rm u:ec2-user:rX,d:u:ec2-user:rX /var/log
  endscript
}
