The minimum amount of
gas required by the Ethereum network to execute a smart contract …
That will transfer funds …
Is currently set at twenty-one thousand (21,000)
gas units plus the value of all other resident op-code functions used by your contract, if any.
The fee schedule per op-code expressed in units of
gas is set annually by the directors of the Ethereum foundation and is also subject to change.
Note. All smart contracts executed over at the Ethereum network must be written in Solidity, the default Ethereum network development language.
The (.sol) files are then compiled into byte-code for the Ethereum Virtual Machine, or EVM to work upon.
So, to sum …
If you wish to send
ether from one account to another over the Ethereum network, you will have to pay a current fee of at least twenty-one thousand (21,000)
Therefore, when figuring out how much
ether to send from one account to the other, you must also account for the expected override snipped by the Ethereum network to process your transaction based on the complexity of your smart contract.
If we can calculate the number of
gas units our smart contract will consume when executing over the Ethereum network …
Then, given the current price of
gas over at the Ethereum network we should be able to calculate the
gas cost of our contract, as well.
How much Giga-wei, or
gwei of gas are you willing to spend?
Try scoping out the current action of the Ethereum network by viewing the Ethereum Network Dashboard over at Ether Stats dot net.
In column two of the Ethereum Network Dashboard under the subtitle ‘Uncles’ you will find the current price of
gas at the Ethereum network.
Currently, the dashboard shows a price of
gas at the Ethereum network equal to twenty (20)
So, if your smart contract is simple, and only requires the sending of
ether from one account to another …
Then you may currently expect to pay twenty (20)
gwei per gas unit.
And, it takes twenty-one thousand (21,000)
gas units just to execute a transfer of
ether from one account to another.
Twenty-one thousand (21,000)
gas units times twenty (20)
gwei per gas unit equals …
gwei, or Giga-wei.
wei is the smallest denomination that an official (ETH) coin can be broken into.
In fact, there are 1,000 zillion
wei per (ETH) coin!
According to the Ethereum Converter, there are one-million (1,000,000,000)
wei in a
gwei, or Giga-wei.
From our previous calculation, we need four-hundred and twenty thousand (420,000)
gwei, or Giga-wei just to transfer funds over the Ethereum network.
That’s four-hundred and twenty thousand million
Or, 420 billion as we say here in America (there are a thousand million in one billion).
Now, if I knew the price of one
wei given there are 1,000 zillion
wei in one
ether coin, or (ETH) …
Then, I could calculate the cost of running my “funds transfer” smart contract one time over the Ethereum network.
(Not counting the time it takes just to figure out the cost of doing so!)
If you login to your Coinbase Dashboard over at Coinbase dot com using two-factor authentication, you will find the current price of one
ether coin, or ETH.
One ETH is currently trading for around $730 USD.
Now, divide $730 USD by 1,000 zillion
wei and you fill find the current price of one
And, remember … we need 420 billion
wei to run our smart contract over at the Ethereum network.
Hint. One thousand zillion equals … a trillion (
1,000,000,000,000) plus another six (6) zeros, or …
Using the trusty, super-large Web2 online calculator over at Zero Calc dot com …
We see one
wei currently equals seventy-three hundred zillionths of one
dollar (USD), or …
Now, if we multiply the current value of one
wei in USD by our requirement of four-hundred twenty billion
wei (just to run our transfer contract over at the Ethereum network) …
Then, we get a total cost per transfer of
$0.0003066, which is still currently less than one-penny (USD).
