Neo: [neox-2.x] Incorrect StateRoot for testnet's block 784078

[roman-khimov]

Describe the bug
If we're to ask for StateRoot at block 784078 from testnet's seed nodes, all ten of them would respond like this:

{
   "result" : {
      "flag" : "Unverified",
      "stateroot" : {
         "version" : 0,
         "index" : 784078,
         "stateroot" : "0x475d72dfaceb5209cc23377c615326fd3a295ae5700822934501f43413b8364e",
         "prehash" : "0xfd0969fc7c672b2246b46e6253eac2ac938a4c58afb8ee9857b09b95ee0ecd77",
         "witness" : {}
      }
   },
   "id" : 5,
   "jsonrpc" : "2.0"
}

It's unverified for obvious reasons, but all ten agree that this is the StateRoot and all subsequent roots are based upon that, so it seems to be an official StateRoot value for this block. I think this is an incorrect StateRoot and the correct one is 0x91a8bc562b2f5c691f31d3339257044c8b9b197e631316d6dda25be1a3ca0db6.

Block state changes
To understand the issue we need to take a look at storage changes being done by this block, this can be done with StatesDumper plugin and for this block we can see the following set of changes:

   {
      "size" : 6,
      "block" : 784078,
      "storage" : [
         {

            "key" : "2f73a155514827186319c3efccbc925d6c45a6ed500fe470c00ea1d17f045737fb83a6f3007739a9d41c02000000000000000000000a",
            "state" : "Added"
         }
      ]
   }

It's not big, just 6 puts, some are changing old values, some are new.

If we're to look back at block's changes we may notice that the value for the key ddeb9aa1bfc353c9c54e21dffb470f65d9c22a0662616c616e63654f700000000000000007 is actually a changed one, so there was some other value at block 784077 that is being replaced. The StateRoot for this block can be seen in this output:

{
   "id" : 5,
   "jsonrpc" : "2.0",
   "result" : {
      "flag" : "Unverified",
      "stateroot" : {
         "stateroot" : "0x711fc10d720c5dfdaba0b86784a1cac6d20c5b8323dbdd7d9732136dcef779b7",

         "witness" : {},
         "index" : 784077
      }
   }
}

And the proof for this path at block 784077 is this:

The key is the same, ddeb9aa1bfc353c9c54e21dffb470f65d9c22a0662616c616e63654f700000000000000007, and the proof length is the same consisting of:

• branch at d
• branch at d
• branch at e
• extension for b9aa1bfc353c9c54e21dffb470f65d9c22a06
• branch at 6
• branch at 2
• extension for 616c616e63654f700000000000000007
• a leaf, finally

Notice that for the sixth step (branch at 2) that corresponds to ddeb9aa1bfc353c9c54e21dffb470f65d9c22a0662 prefix we have a branch node with non-null options for 2 and 9 for the block 784077, but we have options 2, 4 and 9 for the block 784078, which tells us that we have something in the trie with a prefix of ddeb9aa1bfc353c9c54e21dffb470f65d9c22a0664 and this something was created by the block 784078.

But if we're to look back at the change set for this block there is nothing with the prefix of ddeb9aa1bfc353c9c54e21dffb470f65d9c22a0664. More than that, there is nothing with this prefix added at least up to 3.6M height (most probably even higher, that's just the state dump I have at hand). So this branch seems to be an erroneous one and it shouldn't exist. Removing it should lead to proper StateRoot value for this block.

@KickSeason plz, have a look.

[ZhangTao1596]

Marvelous analysis. I'm looking into it. How did you notice this?

[roman-khimov]

How did you notice this?

Half a day staring at pictures like this does wonders:

On a more serious note we have an implementation of MPT (and other neox-2.x features) in neo-go now and this is the first block (for now) where our StateRoots start to differ even though storage changes are exactly the same.

[ZhangTao1596]

@roman-khimov Is the StateDumper json data from neo-project/neo or neo-go?

[roman-khimov]

From neo-project/neo, of course, but it's the same. It's all the same as of current neo-go.

[ZhangTao1596]

Thanks. I'm trying to find the reason.

[ZhangTao1596]

I download the neox-2.x release, resync the blocks and get the same StateRoot with neo-go on MacOS.
Will try on linux and check the seeds.

To share the results.

[roman-khimov]

I've just compared the result with another node and it actually has a proper StateRoot. More than that, we have the same StateRoot values up to 4,2M (I've not yet completed import of current blocks into neo-go node). So it's just something with seed nodes and not an implementation issue (or maybe an implementation issue that somehow only affects seed nodes, but that's unlikely). Which is good, actually.

[ZhangTao1596]

Hi @roman-khimov. @superboyiii just find that installation of Nep5Tracker plugin will cause the issue.

[superboyiii]

@roman-khimov The issue is here: neo-modules issue #258.

[roman-khimov]

Wow. That's a surprise. But at least we know now that pure node doesn't have this problem.

[superboyiii]

Wow. That's a surprise. But at least we know now that pure node doesn't have this problem.

Yes, we'll try to find out the issue in this plugin and make a hot fix.

[superboyiii]

@roman-khimov We fixed it in RpcNep5Tracker：https://github.com/neo-project/neo-modules/pull/259

[Tommo-L]

Close? It was fixed in neo-project/neo-modules#259
