What is a Cryptocurrency and how does it work?
Cryptocurrency is digital currency issued without the need for a central bank. It is created in a decentralized ledger called a blockchain. It uses complex cryptographic functions to secure transactions.
What is a Blokchain?
A blockchain is a ledger of transactions grouped by blocks. The blocks are linked together through cryptographic keys thus forming a chain.
What is Gas price?
Gas price is the amount of Ether you accept to pay for each unit of gas. Gas price is often mesure in Gwei.
What is Gas limit?
Gas limit refers to the maximum amount of gas you are willing to consume on a transaction. Smart contract usually consume more computational work than a simple ETH transfer. When you set the gas limit, anything that is not consumed is returned to you. On the other hand, if you set a limit that is too low that does not allow the execution of the transaction, it is canceled but the gas that was consumed will not be returned to you.
Who set Gas price and Gas limit?
You set gas price and gas limit. Note that miners will preferably execute transactions offering a higher gas price, as they earn the fees that you pay. Miners will be less inclined to execute transactions with lower gas fees set.
What are Miners?
In decentralized systems like Ethereum, miners are responsible for processing transactions, validating them, and creating the blocks of the blockchain in a chronological order that secures the network. They are paid to do this work with gas and fees.
What is MetaMask wallet?
MetaMask is a wallet used to interact with the Ethereum blockchain. It allows access to their Ethereum wallet through a browser extension or mobile app, which can then be used to interact with decentralized applications like Eterneum.io.
What are non-fungible tokens (NFTs)?
NFTs are tokens that we can use to represent ownership of unique items. They let us tokenise things like art, collectibles, even real estate. They can only have one official owner at a time and they're secured by the Ethereum blockchain – no one can modify the record of ownership or copy/paste a new NFT into existence. Eterneum.io is based on NFTs.


What is Eterneum.io?

How many tokens can I enter in the ledger?
You can create as many tokens as you want as long as you comply with the terms and conditions of use of the site Eterneum.io.
Is it possible to change the data after submission?
The smart contract governing Eterneum.io does not allow the alteration and modification of data, nor the tokens transfer to a third party.
Is it possible to sell the token I have created?
No, it is not possible.
How the data are stored ad vitam aeternam?
The tokens created by Eterneum.io are stored in the Ethereum blockchain and the information associated is saved in a unique IPFS address. The IPFS storage as well, as the Etherneum blockchain ledger, guarantees its sustainability even if Eterneum.io disappears in the future.
I've validated my transaction but my data does not appear in the Eterneum.io ledger page.
It might occurs if you stop or close your browser before the end of the process. We check the recorded transactions every day. if your token is correctly registered in the Ethereum blockchain, we will show your data in the Eterneum.io ledger page.
I can't connect my MetaMask Wallet to Eterneum.io.
After installing MetaMask extension, please reload the browser page then click on the Connect button. Please also check if your MetaMask account is not locked.
My Geo PlusCode is not valid. Why?
You have to enter the full pluscode located in the pluscode url, not the short one with a city name.
How can I save my dragon?
We use vectorial SVG format to design the dragons. You can use any browser plugin like Chrome SVG Export to export and save the image as PNG or JPG. Go to the ledger page, locate your dragon and export it.
