With many new traders entering an existing market, a lot of terminologies could easily get overwhelming, that's why we've compiled a list of frequently asked questions and provided easy-to-understand explanations.
What is blockchain?
A blockchain is similar to a database except in the way that the information is stored. Blockchains are decentralized, meaning there is no single operator or entity that has control. In the case of Bitcoin, anyone can run their own node, which contains a complete copy of the blockchain, to both secure networks and interact directly with the blockchain. In this way, it is censorship-resistant. Blockchains record data in blocks and the blocks are attached chronologically one after the other. Each new block contains a reference to the previous block, making it a chain of blocks. Blockchains can store many types of data securely. For Bitcoin, it is used to store transaction data. It’s important to note that once a block is added, its contents are immutable, which means the records of those transactions are permanent and unalterable. Most blockchains, Monero being a notable exception, are fully transparent and publicly verifiable. Anyone with an internet connection can view transaction history or address balances by visiting the chain’s block explorer.
What is the process of a blockchain transaction?
Here is an example to illustrate the process:
2. He enters Debbie’s public BTC address, the amount and fee he is willing to pay.
3. He clicks “Send” and the wallet signs the transaction with Bob’s private key.
4. The transaction is sent out to all the nodes and verified as valid. The transaction then awaits inclusion in the next block.
5. A miner successfully solves the mathematical puzzle and earns the right to create the next block. Bob’s transaction gets included.
6. The miner announces the new block and the nodes verify and propagate it across the network.
7. Debbie sees the transaction’s first confirmation. Each subsequent new block yields another confirmation for the transaction. She waits for three confirmations and then hands over the car keys to Bob. The deal is done.
What are transaction fees?
A transaction fee is a price paid to complete a transaction on the blockchain. Computers are used in various ways to verify transactions and subsequently add those transactions to the blockchain ledger. Fees provide the incentive (beyond the block reward) for miners to mine and to stake. For most blockchains, the higher the volume of transactions, the higher the fee will be to get your transaction included in the next block.
What are gas fees?
Gas fees are transaction fees on the Ethereum network. The more you pay, the faster the transaction. When the Ethereum network has a high volume of transactions, the cost of transactions can increase significantly.
What are the different types of crypto wallets?
A crypto wallet is a software or a hardware device that allows users to both securely store their crypto assets and interact with the blockchain. Crypto wallets come in many forms.
Hardware wallets: A physical device that stores the private keys of your crypto offline. Access to it is protected by a user-defined PIN.
Paper Wallet: A physical piece of paper containing a public key, private key, and sometimes a corresponding QR code. This paper must be secured, as anyone with access to the paper has full access to the crypto in the wallet.
Desktop Wallet: Software issued by the coin/token developers or others that allow users to store cryptocurrency on their PC. Wallets should be encrypted using a strong passphrase.
Web Wallets: Generally considered the least secure, web wallets can be installed in supported browsers. While convenient for sending funds quickly, your encrypted private keys are stored on the servers of the web wallet provider, which can be a security risk.
Mobile wallet: Wallet software that allows users to store their individual cryptocurrencies on handheld devices.
What is staking?
Like mining, staking validates transactions, but it does so a proof-of-stake mechanism instead of proof-of-work.
Holders of tokens can take advantage of program, where a proportion of the transaction fees paid in are distributed to holders on a quarterly basis.
What is governance?
Governance refers to the set of processes that are used to control various aspects related to a digital asset. is a community-managed project, and as such token holders will be able to vote on issues relating to future iterations and implementations of the Exchange.
What is Vesting?
Many new crypto projects offer a pre-sale of their proprietary tokens to early investors. To prevent dumping on the open market at launch, some new projects lock the pre-sale tokens for a certain period of time. This is called a vesting period. In the case of the Pre-sale tokens, for example, a proportion of the “locked” tokens are released weekly over a 9-week period.
What is a liquidity pool?
A liquidity pool is a collection of funds locked in a smart contract. These funds provide the capital for trading pairs on decentralized exchanges.
60% of the capital raised via the Pre-sale was forwarded to the liquidity pool on .
What is the difference between Centralized and Decentralized Exchange?
Centralized exchanges are web platforms that allow people to buy and sell cryptocurrency, as well as provide on-/off-ramps from/to fiat currencies. The transactions on centralized exchanges are off-chain. These exchanges act as third-party custodians in that user funds are stored on their servers, and the exchange is responsible for the security of those funds. With centralized exchanges, clients do not have access to private keys of the digital assets in their accounts. Instead, users actually hold an IOU until they withdraw the tokens/coins to their personal wallets.
On decentralized exchanges, people can also trade digital assets, but the assets are not under the custody of any third party. Instead, all transactions are written to the blockchain and the funds are swapped from one to another. On decentralized exchanges, users have full control over their funds at all times and connect to the platform with their personal wallets.
What is Custo-DeFi?
Custo-DeFi is a new concept coined by Centralex. Custo-DeFi combines elements of both custodial exchanges and decentralized exchanges. It ensures that funds are stored in an ultra-safe, semi-custodial environment. Thanks to a partnership with Fireblocks, users will have the freedom to participate in the full range of DeFi options, including trading on UniSwap, from within the Centralex Exchange platform. It’s worth repeating here that Centralex will never store any private keys on its servers.
What is an NFT?
NFT stands for non-fungible token and it is a unit of data stored on a blockchain. The blockchain certifies that the asset is a unique one with unique identifiers that cannot be duplicated. NFTs provide proof of ownership and users can trace the ownership/transaction history of the NFT right back to its creation. NFTs can cover a wide range of items, from collectibles to land titles and everything in between. Like DeFi, NFTs remove the need for intermediaries between seller and buyer.

How to avoid crypto scams, a few tips to help along the way:
- Research the individual team members of a project before you invest.
- Beware of generic-looking websites using simple templates.
- Read the project’s whitepaper carefully. If the quality is low in both content, style, and grammar, it should set off warning bells.
- Beware of promises that are too good to be true.
- Avoid projects that promise free money/crypto or ridiculously ROI.
- Find out what other serious investors think of the project before investing.
- Visit the project’s social media platforms and look for red flags. Ask questions.
