Consensus

VeChainThor adopts the PoA (Proof-of-Authority) consensus protocol, instead of neither PoW (Proof-of-Work) nor PoS (Proof-of-Stake). Members in the whitelist requiring KYC (know-your-customer) identity verification are in charge of and responsible for the operation of the blockchain network. Concerning the safety issue, we leverage DPRP protocol to mess up the order of packer who pack the block, making sure the sequence of order of packers varies each time when packing the block.

Block Generation Speed

The default interval of block generation is 10 seconds, but the concrete timestamp interval depends on the specific situation.

Orphan Generation/suggestion

It is possible to generate orphan block and it is suggested to verify the fork situation every 12 block interval.

Dual token precision

The precision of both VET and VTHO is 10^18 Wei. VTHO is generated from staking the VET and it is consumed for payments and smart contract execution on the VeChainThor blockchain

Are the failed transactions going to be recorded on the chain? Is the transaction gas going to be deducted?

When you send tokens, interact with a contract, send VET/VTHO, or do anything else on the blockchain, you must pay for computation. That payment is calculated in Gas and gas is paid in VTHO. Regardless of whether your transaction succeeds or fails. Even if it fails, the proposer(authority node) must validate and execute your transaction (compute) and therefore you must pay for that computation just like you would pay for a successful transaction.

How does the token swap from ERC20 VeChain token to VET work?

•The ticker symbol for the VeChainThor Mainnet token will changed to VET.

•Token swap ratio is 1:100. One ERC20 VeChain token will be split to 100 VETs on the VeChainThor Mainnet.

Transaction fee calculation

The calculation equation is: VTHO = (1 + gasPriceCoef/255) * baseGasPrice

The VET transfer fee is 21000gas. If gasPriceCoef = 0, the used of VTHO = (1 + 0/255) * 1e15 * 21000 / 1e18 = 21 VTHO

The priority of a transaction in transaction pool can be raised by adjusting gasPriceCoef. For example, if gasPriceCoef =128, used VTHO = (1 + 128/255) * 1e15 * 21000 / 1e18 = 31.5 VTHO

Always subject to the actual network parameter

Where can I find the contract address which I just deployed?

Once contract successfully deployed, the contract address can be found in transaction receipt.

Why I Cannot synchronize blocks?

The reason for having an issue to synchronize with blocks is because the local time might be inaccurate. Please synchronized with NTP(Network Time Protocol) server .

What is the base generation rate of VTHO generation speed?

The generation speed of VTHO is 0.000432 per VET per Day

The generation speed shown here is indicative only. the actual generation speed should subject to actual network

What is intrinsic gas ?

The intrinsic gas for a transaction is the amount of the transaction used before any code runs. in other words, it's a constant "transaction fee" plus a fee for every byte of data supplied with the transaction.The gas in the transaction needs to be greater than or equal to the intrinsic gas used by the transaction.

Intrinsic gas = txGas + clauses.type + dataGas
  • txGas = 5,000
  • Clauses type:
    1. Normal transaction : 16,000
    2. Contract creation : 48,000

How to calculate total transaction gas ?

In VeChain Thor clauses allows a single transaction to carry out multiple tasks. Therefore, it needs to execute all the clauses cost in the transaction.
