Crypto Dictionary

The phrase "financial technology" is an acronym for "financial technology." It relates to the financial sector's technological development. FinTech is a growing area, and a diverse variety of companies, from start-ups to established corporations, are embracing it. FinTech is forward-thinking, with the goal of streamlining both firms' and customers' financial processes through technology automation. Data science, machine learning algorithms, cryptocurrencies, and blockchains are a few examples of financial technology. These developments have the potential to improve the speed, security, value, and inclusiveness of financial procedures.

Forge is a decentralised content delivery network built on fog computing and artificial intelligence (AI), with participants making bitcoin settlements and transactions being recorded in blockchain. Anyone with a PC or laptop can join the ForgeCDN network and become a node (a static IP address is necessary). When a network member connects to the network and pumps traffic from content distributors to end users, they are paid in FORGE (money), which is issued by and based on the blockchain platform Etherium.

The fork is a review of blockchain rules that cause network fragmentation. Cryptocurrency blockchains are usually split, hundreds or thousands of nodes in a network. When a developer or community member initiates a blockchain update, some nodes will update their machine, creating a “new” fork chain. Updates may be related to changes in block size, mining awards, and more. There are two types of forks: hard and soft forks. The soft fork occurs due to major changes in the blockchain. All nodes must decide whether they want to join a new protocol or remain as part of an old series. In contrast, a soft fork is an update with a back-to-back protocol that only needs a lot of notes to be updated to avoid splitting. It is important to note that some forks may be used aggressively to curb cryptocurrency or as a scam. In addition, the value of the blockchain currency may fluctuate over time.

Front running is the illicit practice of making transactions based on insider information. Front runners utilize pending or future transaction data to anticipate changes in the value of an asset. Front running is a problem in all financial markets. Cryptocurrencies, on the other hand, are vulnerable to certain forms of front running. Miners that acquire access to pending transaction data in the mempool on blockchains can use the information to conduct a trade. To go ahead with the original transaction, the front runner can utilize insertion, displacement, or suppression. In addition, frontrunners can target initial coin offers and usernames. To avoid front running, networks might use strategies such as transaction ordering and improved secrecy.

FTX is a centralized cryptocurrency exchange specializing in derivatives and leveraged products. It supports most commonly traded cryptocurrencies.

Full node wallets download full copies of the blockchains on which they operate. A blockchain node is a computer that participates in a blockchain network. They operate on their own blockchains as complete nodes. As a result of this method, wallets no longer need to rely on other parties to obtain blockchain data. As a result, full node wallets are more trustworthy and safe than light wallets, which only store a portion of the blockchain data.

Fundamental analysis involves assessing all market components, including domestic and global issues, as well as political and economic situations. It involves research of everything that has the potential to impact the value of a security, from macroeconomic issues like the state of the economy and industry circumstances to microeconomic elements like the effectiveness of the company's management.

The ability of an asset of an equivalent denomination to be interchangeable is referred to as fungibility. Most fiat currencies, such as the US dollar, and some cryptocurrencies, such as Bitcoin, are examples of fungible currencies. Fungible cryptocurrency tokens, like conventional currencies, may be broken into smaller portions and readily swapped. Individual tokens have no distinctive value and should be worth the same amount. The Ethereum blockchain's ERC-20 standard established a technological framework for issuing fungible tokens to facilitate trade.

Gas refers to the cost of completing tasks in the Ethereum blockchain. Gas represents an intangible unit of calculation in the network and is paid for by parts of Ethereum's native cryptocurrency, Ether, called gwei. Like car fuel, gas allows the Ethereum Virtual Machine to continue operating. Everything that is done in the Ethereum blockchain uses the power of integration, and gas revenue support miners out of the calculation. Users can set a "gas limit" on the functions, thus limiting the amount of gas used. Gas is reduced in the amount of Ether. However, its price is simulated by network activity. Gas costs help maintain network security by reducing the risk of service interruptions and endless loops on smart contracts (among other things).

The initial block in a blockchain is known as a genesis block. Because of 0-based indexing in computer science, it is commonly referred to as "Block 0" on a blockchain. Some blockchains, however, refer to the genesis block as "Block 1." The genesis block is the only one that lacks a hash link to a prior block. Hard-coded genesis blocks are common. The genesis block of Bitcoin has no transaction data. It reads,  “Chancellor on brink of second bailout for banks.” The mining reward from Bitcoin's first block is never spent.

A gossip protocol (sometimes known as an "epidemic protocol") is a method for disseminating information across decentralized networks. It is similar to how gossip spreads in a human social network. For starters, a certain piece of knowledge is only known to a small group of people. The information is then disseminated to others, resulting in a chain reaction in which the entire group is aware. Nodes in a decentralized network send transaction data to a limited number of nearby nodes. This process is repeated until the complete network of "full nodes" has stored the same data. In general, the gossip protocol is more scalable and fault-tolerant than a single node broadcasting data to the whole system. However, because nodes must receive the same data several times, the procedure is time-consuming.

Ethereum gas fees are calculated in terms of ‘Gwei’, a smaller unit for ETH. One Gwei can be equated with 0.000000001 ETH, making it perfectly small for calculating the gas fee.Total Gas Fee = Gas Unit Limits * (Base Fee + Tip)

A hard cap is the maximum number of tokens the project expects to sell to end the initial financing round.

A hard fork is a substantial change to the protocol of a blockchain that is not backward-compatible. Hard forks are the creation of blockchain systems that diverge from the original chains. Nodes must "decide" whether to join the new protocol or not. This procedure generates two incompatible parallel chains, each with a duplicate record of the previous chain, including data about all users' assets. Hard forks often trigger one of two responses from miners. In one scenario, nodes upgrade their software willingly to adhere to the new protocol of a scheduled hard fork. Occasionally, though, community disagreement occurs, resulting in a blockchain split. Nodes that agree with the changes join the new forked-off chain, resulting in the creation of a new version of the currency, whereas nodes that disagree do disagree remain on the original chain. Bitcoin hard forks have created alternative Bitcoin currencies such as Bitcoin Private and Bitcoin Cash. The price of a blockchain’s native currency may become volatile during a hard fork. 

Hashes are created when a hash function receives data and outputs a fixed-length code. Cryptographic hashes, which are employed on blockchains, function similarly to data fingerprints. Hash functions are deterministic in nature. Identical data inputs should result in matching codes, whilst diverse data sets should result in distinct codes. Even minor changes in the submitted data should cause the hash to alter in order to prevent the input from being guessed. Hashes are used for security and are typically prediction resistant, making reverse engineering nearly hard. A significant avalanche effect is produced by good cryptographic hash algorithms, minimizing any correlation between input and output. Hashes are also often computationally efficient, thus they do not slow down the network. For generating hashes, a number of algorithms are available. The SHA-256 algorithm is used by Bitcoin.

Hash pointers are an important component of blockchain security. A "genesis block" is the first block in a chain. Following this basic block, the subsequent blocks use hash pointers to refer back to previous blocks. Individual blocks are linked together using hash pointers. The hash of all of the data in the block before it is stored in hash pointers. If an effort is made to change prior data, the hash of the updated data will no longer be appropriately matched to the pointers in follothe wing blocks. This increases blockchain security by making past data immutable and tamper-evident.

The hash rate measures the efficiency and performance of a mining equipment in the context of Bitcoin and cryptocurrencies. It specifies the speed with which mining gear attempts to compute a valid block hash.

Hash Time-Locked Contracts are smart contracts that are used to strengthen the security of trustless over-the-counter transactions across blockchains. HTLCs, which are used on atomic swaps and the Bitcoin lightning network, decrease risk by assuring that transactions are time-bound. These contracts indicate that in order for the transaction to be legal, both parties must acknowledge the stated payment within a certain deadline. If either side does not validate the payment within the specified time frame, the transaction is terminated. Hashlocks and timelocks are essential components of HTLCs. The transaction initiator generates a key and passes it through a hash function to create the hash lock. To unlock the hash and validate the transaction, the linked private key is utilized. After completion, the preimage saved hash is made public. If the transaction is not completed the payment is invalid if it is not received within the time limit specified, and the timelock returns the bitcoin to its original owner.

HealthTech is an abbreviation for "health technology." It refers to any health service or product that is delivered using digital technology and has been used both within and outside of the traditional healthcare environment. Common examples of health tech include wearable devices and home diagnostic equipment. Because of the broad use of health tech solutions that provide quicker and more efficient health-related outcomes, health tech has emerged as one of the fastest-growing verticals in the healthcare industry. Blockchains offer a wide range of potential applications in health tech. Blockchains, for example, enable the decentralized storage of enormous amounts of personal medical data and medical records, which may be made available to providers considerably more swiftly and securely than traditional systems.
