Summary

After the end of the validation period, each validator checks other validators for the number of blocks they have processed in this last validation period. If the number of blocks is not enough and no one has sent a complaint about this idle validator yet, the validator creates a complaint. The validator also checks the submitted complaints and if they are valid and he has not yet voted for the fine of this idle validator during this validation period, he votes for the complaint.

Since most of the network validators use mytonctrl, the functionality of creating a complaints (to fine idle validator) and voting for complaints was implemented in mytonctrl.

The author of the algorithm and implementation is a igroman787.

In the process of work mytonctrl does:

Implementation of detecting idle validators and checking complaints made in the lite-client, mytonctrl just calls these methods.

Testing Period

At the beginning, the fine is reduced to 101 coins. This is done in order not to scare away validators during testing.

The validator can be fined only once during the validation period.

So in order to participate in the slashing process now, you need to use the last code from https://github.com/newton-blockchain/ton/

In the future, the fine will be returned to significant values.

Detailed description of the algorithm

0. Time to check, create and vote a complaint

We can create a complaint only at a certain period of time, when the elector has frozen the validators' stakes. We will take the time intervals from network config 15:

lite-client> getconfig 15

ConfigParam(15) = ( validators_elected_for:65536 elections_start_before:32768 elections_end_before:8192 stake_held_for:32768)
x{00010000000080000000200000008000}

Here we are interested in the stake_held_for parameter, which is equal to 32768 seconds. This means that within 32768 seconds after the end of the validator's validation cycle, we can check, create and vote for the complaint.

We also need the utime_until parameter, which will be the beginning of the time interval:

lite-client> getconfig 32

ConfigParam(32) = (
  prev_validators:(validators_ext utime_since:1617526392 utime_until:1617591928 total:92 main:92 total_weight:1152921504606846933
    list:(hme_root
      root:(hm_edge
      ...
      ...
      ...

So in our example, we can check the work of the validator, create a complaint and vote for it from 05.04.21 03:05:28 to 05.04.21 12:11:36 (UTC).

1.1. Checking the work quality of the validators

We will check the work of the validators with the checkloadall {utime_since} {utime_until-60} {file_prefix} lite-client command. We do not take into account the last 60 seconds of the validator's work, since this is a borderline interval and can cause us problems:

lite-client> checkloadall 1617526392 1617591868 cla

Here we can see that 5 validators were found that worked poorly. 5 log files were created for these validators. We will need them in the next paragraph to create a complaint.

1.2. Checking that the complaint does not exist yet

Before creating a complaint, we need to check that this complaint does not exist yet in network. Otherwise, our complaint will not make sense and we will waste our coins. We will check by calling the elector method runmethod {fullElectorAddr} list_complaints {utime_since}:

lite-client> runmethod -1:3333333333333333333333333333333333333333333333333333333333333333 list_complaints 1617526392

We can transform the received data into a more readable form. The conversion code in python3 can be viewed here (https://github.com/igroman787/mytonctrl/blob/6873aef03cefdf9ef54f204ffe20a1e0ad617d38/mytoncore.py#L1723).

Another option would be to convert the validator pubkey to a number (hex2dec):

We see that a complaint has not yet been created for the last idle validator. For this last validator we will create a complaint.

1.3. Creating a complaint

To create a complaint, we will use the fift script envelope-complaint.fif {utime_since} {complaint_boc} {output_filename}. It is assumed that you have already completed the previous tutorials on working with fift (https://ton.org/HOWTO.txt).

> fift -s envelope-complaint.fif 1617526392 cla-5.boc ecf-5.boc

Loading complaint from file `cla-5.boc`...
Query id is 6947638327042933901 
resulting internal message body:...
(a total of 33984 data bits, 162 cell references -> 4793 BoC data bytes)
(Saved to file ecf-5.boc)

Here we got the ecf-5.boc file that we will use in the next paragraph. Do the same for the each other validator.

1.4. Signing a complaint by a wallet

We sign the file with the complaint fift -s wallet.fif {wallet_path} {fullElectorAddr} {seqno} {amount} -B {boc_filename} {result_filename}:

> fift -s wallet.fif validator_wallet_001 -1:3333333333333333333333333333333333333333333333333333333333333333 3815 100 -B msb.boc result

2.1. Checking an existing complaint

To punish an idle validator, we need to collect 2/3 of the votes of all validators.
However, before voting for a complaint, it must be checked - whether the complaint is indeed correct. To do this, we first download these complaints from the net with the savecomplaints {utime_since} {file_prefix} lite-client command:

Here lite-client advises us to vote on the complaint. Let's check other complaints in the same way.

We also need to check that we have not already voted on any complaint for this validator (identified by the public key) during this given validation period. We must do this check so as not to fine the validator more than once during the validation period.

2.2. Vote on complaint

After checking the complaint, we must vote for it. Create a file for voting with the command complaint-vote-req.fif {validator_index} {utime_since} {complaint_hash} {filename}, where validator_index is the ordinal number in the list of validators (can be counted in getconfig 34, the count starts from zero). In our example, our validator index will be 25. complaint_hash is the hash of the complaint in decimal (hex2dec, 6275F0A1EF13D0026AB9326E18C34D58637A381E4FED6A8705DA3600915D2AA8 --> 44535041052591608287425708264402274110695802669646080627861555422994582284968):

Here we are interested in the field 56744350001960697E786275F0A1EF13D0026AB9326E18C34D58637A381E4FED6A8705DA3600915D2AA8. We will need it further.

2.3. Getting a validator key

For the next point, we need a validator key, we will take it from the validator configuration file (/var/ton-work/db/config.json). We are interested in the validators section:

  "validators": [
    {
      "@type": "engine.validator",
      "id": "SF5w6nzqguTIbcj1kZKmnAeTppRbeKxJ8U++wZY8dWo=",
      "temp_keys": [
        {
          "@type": "engine.validatorTempKey",
          "key": "SF5w6nzqguTIbcj1kZKmnAeTppRbeKxJ8U++wZY8dWo=",
          "expire_at": 1617657764
        }
      ],
      "adnl_addrs": [
        {
          "@type": "engine.validatorAdnlAddress",
          "id": "6t0DjIuTG/yALmcl1XWBVwYwxVrvcYHIdIxKj3kHzfc=",
          "expire_at": 1617657764
        }
      ],
      "election_date": 1617591928,
      "expire_at": 1617657764
    },
    {
      "@type": "engine.validator",
      "id": "nVC3UCMyiXL+XjDGoiuH3GOmYwexIwxmLoRWVo6Ds+o=",
      "temp_keys": [
        {
          "@type": "engine.validatorTempKey",
          "key": "nVC3UCMyiXL+XjDGoiuH3GOmYwexIwxmLoRWVo6Ds+o=",
          "expire_at": 1617723300
        }
      ],
      "adnl_addrs": [
        {
          "@type": "engine.validatorAdnlAddress",
          "id": "6t0DjIuTG/yALmcl1XWBVwYwxVrvcYHIdIxKj3kHzfc=",
          "expire_at": 1617723300
        }
      ],
      "election_date": 1617657464,
      "expire_at": 1617723300
    }
  ],

Here we see two sections. We need to select the one that is currently relevant. For example now unixtimestamp = 1617644084. So we need the first section (1617591928 < 1617644084 < 1617657764).
Take the key and convert it to hex (base64 to hex): SF5w6nzqguTIbcj1kZKmnAeTppRbeKxJ8U++wZY8dWo= --> 485e70ea7cea82e4c86dc8f59192a69c0793a6945b78ac49f14fbec1963c756a. So we got the validator_key.

2.4. Getting the signature of the validator

Next, we need to get the signature of the validator with the sign {validator_key} {data} command:

validator-engine-console> sign 485e70ea7cea82e4c86dc8f59192a69c0793a6945b78ac49f14fbec1963c756a 56744350001960697E786275F0A1EF13D0026AB9326E18C34D58637A381E4FED6A8705DA3600915D2AA8

got signature dE+W+Bmcvs37II+jxOtlRrPd998wwv0eAY0zU3ajeRyp2SpSAnsn6z48Cd/J2qV4V5qCpBppKOZ4BkV643EHAg==

2.5. Getting the public key of the validator

For the next point, we need validator_pubkey. We will get it with the exportpub {validator_key} command:

validator-engine-console> exportpub 485e70ea7cea82e4c86dc8f59192a69c0793a6945b78ac49f14fbec1963c756a

got public key: xrQTSC95c8r0XJhPN+O5Hzfip7t5f83BuVNU4FD3cv/U5+ie

2.6. Adding a validator signature to your vote

The next step is to add the validator signature to the message with our vote with the complaint-vote-signed command.fif {validator_index} {utime_since} {complaint_hash} {validator_pubkey} {validator_signature} {fileName}:

> fift -s complaint-vote-signed.fif 25 1617526392 44535041052591608287425708264402274110695802669646080627861555422994582284968 xrQTSC95c8r0XJhPN+O5Hzfip7t5f83BuVNU4FD3cv/U5+ie dE+W+Bmcvs37II+jxOtlRrPd998wwv0eAY0zU3ajeRyp2SpSAnsn6z48Cd/J2qV4V5qCpBppKOZ4BkV643EHAg== msb.boc

Validators who do not use mytonctrl need to create their own scripts that implement the algorithm for voting for complaints

Since 2/3 votes are needed to accept a complaint, it is necessary that all validators vote and vote according to the same rules.

The process of creating a complaint can be left to validators who use mytonctrl.

Validators who do not use mytonctrl need to create their own scripts that implement the algorithm for voting for complaints as detailed in #13 (comment):

After end of validation period while the stakes are still holding (paragraph 0):

  • Every N minutes invoke savecomplaints (2.1) (for example mytonctrl does this every 10 minutes)
  • For each complaint invoke loadproofcheck (2.1)
  • For each complaint check that you have not already voted for this validator during this validation period (2.1) (for example you can save previous votes locally; the validator is identified by the public key, the validation period is identified by the time range)
  • For each valid complaint create vote, sign vote and send it (2.2-2.8)

You need to use the last code from https://github.com/newton-blockchain/ton/ so that the amount of the fine does not differ.

https://github.com/newton-blockchain/punisher/ - script for those validators that do not use mytonctrl for some reason.

This script implements receiving complaints about idle or cheating validators, checking complaints and voting for complaints to fine such validators.

If you are using mytonctrl (recommended) you do not need to use this script, as the complete slashing process is already built into mytonctrl.

Note that identifying idle or cheating validators and submitting a complaint for such validators is not implemented in the script and it is assumed that this is done by validators using mytonctrl

This single file script has no dependencies and can be easily reviewed.
