Quantum vs. cloud computing: Key differences?

Cloud computing — or “the cloud” — is an application-based software that distributes computing services throughout the internet, utilizing third-party servers, storage, databases, networking, software, analytics and intelligence to store and process data.  Before cloud computing, businesses had to buy and maintain their own servers containing enough space to prevent downtime and outages and manage peak traffic volume. Still, a lot of server space often went unused, wasting money and resources. The cloud computing ecosystem allows organizations to employ a more efficient and cost-effective solution without requiring expensive hardware, private data centers or software installation, focusing on innovation, dynamic resources and economies of scale. Cloud computing was invented in the 1960s but became more predominant in the 2020s when a more productive computing system was required to handle the challenges of organizations’ remote working that emerged during the pandemic.  Thanks to cloud computing, many businesses can share services instantaneously at any time, other than managing, accessing, and storing data and applications remotely. Using the cloud, they benefit from scalable storage for files, applications and different types of information, saving time and money.

What is a crypto dusting attack, and how do you avoid it?

While it’s unlikely for cryptocurrency users to become victims of dusting episodes, they should still take a few steps to protect themselves against such crypto attacks. Due to increasingly high transaction fees, especially on the Bitcoin blockchain, it’s become more expensive for a hacker to launch a crypto dusting attack compared to a few years ago. Still, cryptocurrency users should take a few steps to secure their funds. Since dusting attacks rely on combining analysis of multiple addresses, if a dust fund is not moved, the attackers cannot track a transaction that doesn’t occur to make the connections they need to “deanonymize” the wallets. Simple measures, including due diligence and education, can go a long way toward tackling these attacks. However, more elaborate methods can also be used to protect a wallet’s funds, and here are some of the most effective practices available: Use privacy tools like The Onion Router (TOR) or a virtual private network (VPN) to increase anonymity and strengthen security. Use a hierarchical deterministic (HD) wallet to automatically create a new address for each new transaction, making it difficult for hackers to trace the thread of your transactions.  Use dust conversion services that automatically swap crypto dust into native tokens to use in future trades. Taking these steps should help users protect their funds. Nevertheless, cryptocurrency users should be aware of other cyber threats besides dusting and deanonymizing attacks. For instance, ransomware is malware designed to deny a user or organization access to their digital files until a sum of money is paid. Cryptojacking is a type of cybercrime where a criminal secretly uses a victim’s computing power to mine cryptocurrency. Cryptocurrency can be useful and efficient technology but can also be at the mercy of malevolent actors who work primarily to steal data and value. This is why users should always use caution and be aware of its risks when dealing with cryptocurrency.

Crypto token supplies explained: Circulating, maximum and total supply

A cryptocurrency’s maximum supply is the total number of tokens that will ever be mined, and it is usually defined when the genesis block is created. Bitcoin’s maximum supply is capped at 21 million, and although anything is possible, its strict protocol and code are built so that no more BTC can ever be mined. Other cryptocurrencies do not have a maximum supply but may have a cap on the number of new coins that can be minted with a specific cadence, like in the case of Ether. Stablecoins, on the other hand, tend to keep the maximum supply constant at all times to avoid a supply shock that could affect and fluctuate the price too much. Their stability is guaranteed by collateral reserve assets or algorithms created to control supply through the burning process. Algorithmically-backed coins are designed to maintain a stable price, but they have drawbacks as they are vulnerable to de-pegging risks. Also, non-algorithmic stablecoins like Tether may risk de-pegging, as happened in June 2022, showing that even coins that should provide more certainty may be at risk. The other two metrics — circulating and total supply — also affect a token’s price, but to a lesser extent than the maximum supply. When a cryptocurrency hits maximum supply, no more new coins can ever be created. When that happens, two main results are produced: The cryptocurrency becomes more scarce and as a result, its price may increase if demand exceeds supply; Miners have to rely on fees to get rewards for their contributions. In the case of Bitcoin, the total supply gets cut in half through a process called the halving, so it is calculated that it will reach its maximum supply of 21 million coins in the year 2140. Although Bitcoin’s issuance increases over time through mining and is therefore inflationary, block rewards are cut in half every four years, making it a deflationary cryptocurrency.

How to stake Fantom (FTM)?

Fantom (FTM) is known for its speed and inexpensive layer-1 blockchain. Like other blockchains (for example, Solana (SOL) and Avalanche (AVAX)) that scale better than their counterpart, it has been dubbed an “Ethereum killer.” After raising $40 million in funds, Fantom launched its mainnet in December 2019. Since then, it has grown to become one of the most popular blockchains, sitting in the top 10 blockchains by total value locked (TVL) with $1.3 billion in TVL. Fantom’s high-throughput blockchain is an open-source smart contract platform. It is scalable and EVM-compatible, meaning you can deploy and run your Ethereum decentralized applications (DApps) on Fantom. Its structure enables the support for its decentralized finance (DeFi), other than managing digital assets and DApps.The Fantom consensus mechanism is an adapted version of proof-of-stake, and it’s called Lachesis. It’s been designed to provide high-speed transactions, low fees and almost instant finality due to the aBFT algorithm. aBFT can scale to many nodes worldwide in a permissionless, open-source environment, offering a good level of decentralization.The Fantom blockchain is powered by its native FTM token, and if you believe in the project and want to grow your FTM stack, you can consider staking Fantom to earn passive income.What is Fantom staking?Staking is making a blockchain more secure by locking up an investor’s digital assets for a certain amount of time. This security is provided by validators who validate transactions with their staked tokens, which becomes an economic incentive for them to behave according to the protocol’s rules.By staking FTM, investors actively participate in securing its network while earning passive income, i.e., FTM rewards. Staking means that tokens will have to be locked up for some time; however, they will still be sitting in the owners’ wallets, only they can access and unlock their funds anytime.How to stake FTMThe minimum stake amount to run a validator is 500,000 FTM to prevent Sybil attacks on its consensus mechanism. Sybil attacks are malicious attacks that involve falsifying multiple identities to gain an undue advantage within a network. As the validator’s required amount is relatively high, it becomes easier to delegate FTM to a validator. A few Fantom staking strategies can be used:Fluid staking: Investors can lock up their FTM token from two weeks to 365 days for better returns. The reward varies according to the length of the staking period; the longer FTMs are staked, the higher the reward rate. Liquid staking: Investors can mint sFTM for improved ROI when liquid staking. They can also stake farmed tokens, participate in liquidity mining, farm LP rewards and more.Custodial staking: Investors can take FTM on a centralized exchange (CEX) like Binance or Coinbase. The staking reward is 1%.To stake on Fantom, users can follow these simple steps:Have a minimum of 1 FTM to stake;Go to the Fantom staking page and click Stake your FTM;You can log in with a compatible wallet, like MetaMask. You can open the wallet from your computer or your mobile device. You can create a new wallet or access an existing one using a mnemonic or seed phrase.Deposit your FTM by transferring them from an exchange or another wallet to your Fantom Opera wallet address.Click on “Staking.”Add a delegation by choosing a validator and an amount. Select your lock-up period and confirm.There are a few options when it comes to optimal Fantom wallets. The Fantom Opera network is a second-layer and EVM-compatible blockchain, meaning that you can use any wallet that works for Ethereum, such as MetaMask, the Coinbase Wallet or a cold wallet like Ledger. After creating an account on Fantom, you can also download your Fantom wallet (fwallet) by clicking on the “Create Wallet” button:Where to stake FTM?Other than its native blockchain network, Fantom can be staked across many platforms, including decentralized exchanges (DEX) and custodial blockchains. Here we’ll look at the places to stake Fantom so you can decide which is the most suitable.How to stake Fantom on LedgerStaking through a hardware wallet like Ledger works through a smart contract interaction, like other transactions. It’s sufficient to stake from the Fantom fWallet by signing Fantom FTM Ledger Nano S application. Then, use the “Stake” menu item on your account.How to stake Fantom on CoinbaseIn September 2021, Fantom announced support for the Fantom network on the Coinbase Wallet. Coinbase Wallet users can access and use the Fantom network and engage with Fantom DApps. Users can connect their Coinbase Wallet account to their Fantom fWallet and conduct activities such as stake FTM and earn rewards.How to stake Fantom on BinanceTo stake FTM on Binance, you have to deposit a convenient amount on the exchange, then go to Binance Earn and pick the suitable product for you; usually, it’s a locked up period of 30, 60, or 120 days. You can choose a more extended staking period for higher returns up to 14%.How to stake Fantom on KucoinSimilarly to Binance, you must deposit your FTM token on Kucoin and go to Kucoin Earn. Then click “Subscribe” to pick the product that suits you better, based on rewards and the time you want to lock your assets.Is it safe to stake FTM?It is safe to stake FTM because the validator node cannot access your staked tokens; make sure not to lose your mnemonic phrase or private key. However, like in other proof-of-stake blockchains, you risk losing a fraction of your stake if the validator is not reputable and misbehaves. It’s safer to select reputable Fantom validators who always have active communities, websites and Twitter accounts.How to stake other tokens on FantomFantom provides a flexible and dynamic ecosystem enabling the staking of several DeFi tokens to earn passive income on your investment. To use any of the following systems to stake their native tokens, you need a MetaMask or any other wallet mentioned above connected to the Fantom Opera network. In this case, Fantom staking acts like a CEX, such as Binance, becoming a marketplace where non-native cryptocurrencies are traded. Here are some of the most popular tokens that are based and can be staked on Fantom:Spookyswap is the biggest DEX on Fantom, with $777 million TVL and BOO being its native token, which can be bonded with FTM for maximum liquidity and to yield farm. To stake BOO, buy the tokens in an exchange or swap them in Spookyswap; connect your wallet to Fantom Opera to view your positions and start earning. BeethovenX is a community-driven DEX, an automated market maker (AMM) and a DeFi powerhouse. Governed by BEETS native token and living on the Fantom Opera and Optimism chain, it yields an APR of 31%. To stake Beets, after depositing some FTM, connect your wallet to Fantom Opera and follow the procedure to choose a validator and the locking time.QiDao is an autonomous and community-governed protocol that sits on Fantom and allows you to borrow stablecoins with zero interest against your crypto assets used as collateral. Loans are paid and repaid in miTokens (stablecoin soft pegged to the USD). Scream is another decentralized lending protocol powered by Fantom, similar to platforms like Compound (COMP) and Aave (AAVE). Users who stake SCREAM tokens can earn around 58% APR, while for liquidity providers, the rewards can be as high as 82% APR.How to run a Fantom nodeValidators run full nodes and are a crucial part of the Fantom network. By running a full node, validators participate in the consensus to boost security and generate new blocks. There are some technical requirements and skills to be considered to run a Fantom full node, and it might be more suitable for a techie operator.Following are the requirements necessary to run a Fantom full node:Minimum requirement: 500,000 FTMMaximum validator size: 15x the self-stake amountMinimum hardware requirements: AWS EC2 m5.xlarge with four vCPUs (3.1 GHz) and at least 4.5 TB of Amazon EBS General Purpose SSD (gp2) storage (or equivalent).Rewards: currently ~13% APY (Normal APY on self-stake + 15% of delegators’ rewards). APY varies based on staked %. For up-to-date APY, check the Fantom Foundation website.A step-by-step guide to running a full-nodeUsers can run a node on their hardware or use a cloud provider. One of the big cloud providers, e.g., Amazon AWS, is recommended.They can set up a non-root user. Install the required building tools; install Go and then Opera.Register their Fantom validator node on-chain. To do this, users need to create a validator wallet that becomes the validator’s identity in the network, required to authenticate, sign messages, etc.Run their own node. To do this, they need to restart their node in validator mode, then close the Opera window by typing “exit.” Then they need to head back to the window where they started their node with the following command: (validator)$ nohup ./opera –genesis $NETWORK –nousb –validator.id ID –validator.pubkey 0xPubkey –validator.password /path/to/password &Users can refer to Fantom’s instructions for full specifications and details on how to run a validator node. How much money can you make staking Fantom?You can earn 5.01% if you choose the minimum lock-up period (14 days) and the minimum amount. The maximum APY is currently 15.31% for the maximum lock-up period of 365 days.The FTM staking rewards calculator will estimate how much can be earned by staking Fantom.FTM and most crypto tokens have dropped by over 90% during the 2022 bear market; therefore, staking will grow the number of your tokens but not necessarily the overall value. It’s also worth considering that staking and locking your tokens up may make your funds illiquid and exiting a position difficult.Purchase a licence for this article. Powered by SharpShark.
