How corrupt is your private Steem Engine node?

4개월 전

Here's a script to check if your Steem Engine node is corrupt. It checks the block sequence as well as transaction organization.

First, install ruby. I like to use the Ruby Version Manager for this part.

Next, install Radiator:

gem install radiator

Then create a file called verify_steem_engine.rb (note: we assume the node is on

block_agent = '')
block_num = 0
previous_hash = nil
trx_ids = {}

while !!(block = block_agent.block_info(block_num))
  block_num % 1000 == 0 and print '.'
  if !!previous_hash && previous_hash != block.previousHash
    puts "\nprevious_hash:      #{previous_hash}"
    puts "block.previousHash: #{block.previousHash}"
    abort("Problem detected at block_num: #{block_num}")
  block.transactions.each do |trx|
    (trx_id = trx.transactionId) == 0 and next
    trx_id, idx = trx_id.split('-')
    if trx_ids.keys.include?(trx_id) && trx_ids[trx_id] != block_num
      puts "\nFound duplicate transaction id (#{trx_id}) already seen in block: #{trx_ids[trx_id]}"
      abort("Problem detected at block_num: #{block_num}")
    trx_ids[trx_id] = block_num
  block_num += 1
  previous_hash = block['hash']

puts "\nVerify complete, ending with block: #{block_num}"

Finally, run it:

ruby -r radiator verify_steem_engine.rb

If everything is fine, you'll see a result like this:

Verify complete, ending with block: 95497

Otherwise, if there's something amiss, I recommend you delete the data directory, download the latest blocks.log file, and replay it.

Having a problem installing gem install radiator, maybe error in the ruby installation?


Usually, documentation is pretty good about guiding you through the ruby install process. It does depend on your specific operating system. But on ubuntu, it boils down to:

gpg --keyserver hkp:// --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL | bash -s stable 
source /home/tender/.rvm/scripts/rvm
rvm install ruby-2.6.0
gem install radiator

Thanks a million, I will definitely check that out

Wow, thanks @inertia for the scripts, it’s help Steemers a great deal!
