EOS RAM and Bandwith Analysis: Airdropping steps on Junglenet

leordev (46)in #eos • 7 years ago (edited)

I was studying about EOS RAM Allocation, CPU and NET bandwith and I was wondering about how much it costs to organize a real airdrop. So I just came up with this small experiment in Jungle testnet which can be totally adapted to Mainnet, because the storage and bandwith are the same you can just adjust the current EOS and RAM prices.

It's actually super simple to Airdrop a token in EOS <3

Create an account for your smart contract
Download the official eosio.token from eos repository
Compile and deploy it to your contract
Create your token symbol and supply
Start issuing tokens

I'm going to cover all the above steps below, let's go!

Default Account creation on Junglenet

Created account eosairdroper from http://dev.cryptolions.io/#account

Here's the initial account balance and stake stats:

$ cleos get account eosairdroper

Deploying the `eosio.token` contract

Simple deploy from original EOS Repo without any changes:

$ cleos set contract eosairdroper ~/eos/build/contracts/eosio.token ~/eos/build/contracts/eosio.token/eosio.token.wast ~/eos/build/contracts/eosio.token/eosio.token.abi

Yeah, the cost to deploy eosio.token is 186.335 Kb with today's version! Ok, the fun begins... Let's create a token!

Creating a token

Default token, 1 billion supply and four decimals exactly like EOS.

Neat! To create a token we spent very little resources, almost nothing...

Issuing some Tokens

Now let's airdrop some tokens!

I'm using some random accounts from the official snapshot (sorry if you are one of them):

No Memo

Testing an airdrop with no memo to another random account ge3dmgenesis: 1000.5425 EOS - it reduced from 128 bytes to 120 bytes of net bandwith usage, no significative changes in cpu and didn't affect anything on RAM, AT ALL - Remember, from the eosio.token contract we don't store the memo anywhere.

Results

If we assume the above values as an approximated average (I would need to load a batch of a couple thousands accounts to make sure), these are the stats that we will need for a full airdrop based on the official mainnet launch snapshot:

Stat	Avg / tx	Total 163,930 Accounts
Net Bandwith	128 bytes	20.98 Mb
Cpu Bandwith	~2.36 ms	386.87 sec
RAM	0.229 kb	37,540 kb

You will eventually want to remove some accounts like B1, exchanges and so on from the airdrop.
Also these are other interesting stats from the genesis snapshot:

Minimum EOS Balance	Number of Accounts
0.0000 EOS	163,930
1.0000 EOS	162,106
5.0000 EOS	148,624
10.0000 EOS	137,950
100.0000 EOS	84,979

Mainnet

As of today's date, a couple hours ago we had an account creation with a RAM price of 0.015 EOS/Kb.

So if you are planning an Airdrop now, with the official genesis snapshot it would cost
around ~563 EOS, which right now translates to $6025.17 (USD). I'm not considering the net and cpu because it fully restores in 3 days, you could separate your airdrop in blocks.

My next step is to run a big batch of thousands of tokens issuing transactions so I can prove all of these stats are correct.

Also a BIG THANK YOU to @nsjames, @syedjafri and @blockliberty for the nice insights, discussions and prices! And of course to this amazing Jungle Testnet @cryptolions

Dan, thanks a lot for your input, it means A LOT to me!

So, that's something that I'm discussing with other fellas... What means "people claim"? I'm already engaged to create a claim action and setup a claim table (intermediary), so when people claim their airdrop I would just transfer from my contract account to the claimer account setting the claimer as the payer.

Am I missing something? It's already out-of-the-box on the issue action? Because it does not look like as the issuer is the payer.

I am confused about this as well, because in the eosio.token contract, the issuer pays for the new tokens storage. Even if you issued to a middleman account, the sender (from) always pays for storage, correct? @leordev I would love to be apart of this discussion with you and your team. I am also thinking about how the eosio.token contract is implemented on the mainnet and how we can create our own tokens using this contract.

The existing code,

auto to = to_acnts.find( value.symbol.name() );
if( to == to_acnts.end() ) {
    to_acnts.emplace( ram_payer, [&]( auto& a ){
    a.balance = value;
});
} else {
  to_acnts.modify( to, 0, [&]( auto& a ) {
    a.balance += value;
  });
}

This means that should the receiver not be pre-existing in the table with the corresponding symbol then the sender pays the RAM cost to create a record to do so.

What if we created a preexisting record where there was a 'register' method which allowed anyone to call it and create an empty record in the to_acnts table, with a balance of 0.0000.

Then, your own computer can listen for such action, check if they're on the airdrop list, and then trigger a transfer action, transferring the tokens to the receiver without such RAM cost.

This wouldn't cast the net as wide as one would like as not every planned recipient would hit this 'register' action, however, you could have an 'Airdrop period' where if you do his this action, you're guaranteed to get the token early/day 1, if you don't, then you'll have to wait a little longer.

hey @johnwilliamson nice idea buddy! with that we don't even need an intermediary table! it looks perfect! I'm still waiting for @dan answer because I don't want to redo any job if he tell us that they are planning or working in something of eosio.token to claim tokens already!

That would mean the tokens are effectively moved from the smart contract account to the users account? or the user just pay the RAM used for his row in the smart contract?

Great write up. Now I need to get up and running so I drop a token while RAM is cheap :p

I was going to ask you a question here but it is probably better for the SE, https://eosio.stackexchange.com/questions/898/get-cleos-without-building-eos

Know of any good instructions for installing cleos on Ubuntu without building a node?
