For the purpose of this article, we'll refer to value as balance. This article will show you how to verify the ownership and balance of our wallet addresses. To verify, you'll need to use an Okcoin audit file and an open-source verification tool.

How to prepare for verification

1. Download our verification tools from GitHub. There are two tools you'll need.
   • VerifyAddress will verify ownership of the wallet address.
   • CheckBalance will verify wallet address balance. Note: rpc.json needs to be configured, in order to configure node RPC or OKLink open API and other related information.
2. Download our audited wallet address files
3. Create a folder for both the downloaded wallet address files and verification tools

To verify the ownership of our wallet addresses, follow the steps in the verify Okcoin's ownership of wallet addresses section

To verify the balance of reserves address, follow the steps in the verification of wallet reserves address balance section

Verify Okcoin's ownership of wallet addresses

You can confirm the ownership of the wallet address published by Okcoin with our open-source tools or third-party tools.

How to verify Okcoin's ownership of wallet addresses with our verification tools

Follow these steps to verify our ownership

1. Open the terminal program on your device
   • Terminal on Mac
   • Command Prompt on Windows
2. Run the provided command and locate the directory of the downloaded folder. In our case, enter the command cd ~/Downloads/proof-of-reserves
3. Enter the following command in terminal (The file name can be replaced with another file that needs to be validated)

Mac

./VerifyAddress --por_csv_filename=okcoin_por_2023051101.csv

Windows

VerifyAddress.exe --por_csv_filename=okcoin_por_2023051101.csv

If the verification is passed, the terminal will return "Verify address signature end, all address passed"

Verification passed

Verify the balance of Okcoin's wallet addresses

Verify by following these steps:

1. Compare the address balance of a specific crypto chain at the snapshot height time with the address balance in the snapshot file published by Okcoin to verify whether they're consistent.
2. Compare the sum of address balance of a specific crypto chain at snapshot height time with the sum of address balance in the snapshot file published by Okcoin to verify whether they're consistent.

When checking the address balance at the height of the snapshot, you can configure node rpc for value query or configure OKLink's open API for value query.

How to verify BTC specified address balance and total balance

1. Install the Bitcoin Core client, synchronize to the latest height, and then roll back the block to the height of the Okcoin snapshot

server=1
rpcuser=Okcoin
rpcpassword=OkcoinWallet

The node output log judgment

2. Configure the parameters

1. Open rpc.json file
2. Configure btc-related RPC parameters in the rpc.json file and save the file, as shown in the figure below

3. Use the tool CheckBalance to verify whether the balance of the on-chain address is consistent with the balance shown in the snapshot file

Verification Steps

1. Open the terminal program
   • Terminal for Mac 
   • Command Prompt for Windows
2. Run the command and locate to the directory of the downloaded folder. In our case, enter the commandcd ~/Downloads/proof-of-reserves

Verify the balance of a single address

1. Enter the following command on the terminal, as shown below (The address and file name can be replaced with other addresses and files that need to be validated)

Mac

3. Compare the Okcoin balance published in the file and the returned result to verify that it is consistent

Verify the balance of all addresses

1. Enter the following command on the terminal, as shown below (The file name can be replaced with another file that needs to be validated)

Mac

2. According to the returned result, the balance of all addresses is shown as below

3）Compare the Okcoin balance published in the file and the returned result to verify that it is consistent

How to verify ETH/USDT specified address balance and total balance

Okcoin has published the addresses on the Ethereum, Polygon, Avalanche and other chains that it owns and the balance of related assets (ETH or USDT). You can use open source tools to verify the balance of related addresses.

Verification steps

1. Open the terminal program
   
   • Terminal for Mac
   • Command prompt for Windows
2. Run the command and locate the directory of the downloaded folder. In our case, enter the commandcd ~/Downloads/proof-of-reserves

Verify a single address balance:

1. Suppose you want to verify whether the balance of the ETH address 0xc5451b523d5fffe1351337a221688a62806ad91a at the specified height is consistent with the balance displayed in the snapshot file (E.g. okcoin_por_2023051101.csv), you need to execute the following command on the terminal

Mac

./CheckBalance --mode="single_address" --coin_name="eth" --address="0xc5451b523d5fffe1351337a221688a62806ad91a" --por_csv_filename=okcoin_por_2023051101.csv

Verify the sum of all address balances of a certain crypto

BTC, ETH, USDT-ERC20, USDT-TRC20, USDT-POLY, USDT-AVAXC, USDT-OKC

3. Compare the Proof of Reserves published by Okcoin to the output results and the balance of the address to the balance in the Proof of Reserves. Consistency proves the sum of the balances that Okcoin has at the time of the snapshot.

Appendix

Use third-party node RPC (e.g. Infura, Alchemy)

Configure the rpc parameters of each chain archive node in the rpc.json file, as shown in the following figure:

OKLink API value verification

Configure parameters related to OKLink open API in the rpc.json file, as shown in the figure below
