- What is the Blockchain?
From the user's perspective, A blockchain is nothing more than an app that provides a personal wallet and allows the user to send and receive tokens. This is how a blockchain works for most users.
Behind the scenes, a blockchain shares a public ledger called a "blockchain". This ledger contains every transaction ever processed and allows a user's computer to verify the validity of each transaction. It uses peer-to-peer technology to operate without a central authority. The management of transactions and the issuance of tokens is done collectively by the network. Moreover, the blockchain can "host" any number of tokens and tokens created by anyone. The blockchain is open source; its design is public, no one owns or controls it and anyone can participate. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, so all users have full control over sending tokens on the blockchain from their own addresses.
- How secure is the blockchain?
Much of the trust in the blockchain comes from the fact that it requires no trust at all. It is completely open source and decentralized. This means that anyone can access the entire source code at any time. So any developer in the world can check exactly how a blockchain works. All transactions and issued tokens can be transparently viewed by anyone in real time. All payments can be made without reliance on a third party, and the entire system is protected by highly audited cryptographic algorithms, like those used in online banking. No organisation or individual can control it, and the network remains secure even if not all of its users are trusted.
- What is a token?
A blockchain is a transaction network. It can host a large number of so-called "tokens", which are controlled only by creators. Nevertheless, tokens are tied to one kind of blockchain and you must first create a wallet that fits this kind. Then you can use the private key and public key to send and receive tokens.
- What is a private key and a public key?
From the user's point of view, the private key of a wallet is comparable to the access data to a bank account. In this context, the public key is comparable to the account number of the same bank account.

- How does sending and receiving tokens work?
AlkCoin transactions are easier to make than purchases with debit or credit cards and can be received without a merchant account. Payments are made from a wallet, either on your computer or smartphone, by entering the recipient's address and payment amount and pressing send. To make it easier to enter the recipient's address, many wallets can get the address by scanning a QR code or by touching two phones with NFC technology. If you want to send tokens, you will need a small amount of the right underlying token of the blockchain in your wallet to pay the transaction fee.
