Development of Blockchain

This page is a Fittyx learning article. It explains what a blockchain is, how the idea developed, and how it relates to this platform. Fittyx is a centralized exchange for spot, perpetual futures, options and copy trading. You trade the platform's ledger of on-chain assets; matching happens on Fittyx, not on a public chain. Trading still requires a logged-in account.

What a blockchain is

The idea of a blockchain was introduced in the Bitcoin whitepaper, "Bitcoin: A Peer-to-Peer Electronic Cash System". In Bitcoin, the chain is the ledger that records transfers. A blockchain is a sequence of data blocks linked with cryptography.

On a public chain, many independent nodes keep a copy of that ledger. This page does not reprint the whitepaper. It only states the idea as it is commonly used: a shared, append-oriented record of transactions.

How a public chain typically works

A public chain is often described as bookkeeping. The exact rules belong to each network. Bitcoin, for example, uses proof of work. Other networks use other consensus rules. The usual steps are:

1. New transfers are collected and proposed as the next block.
2. Participants follow that network's consensus rule to decide which block is appended.
3. Other nodes check the block and extend their own copy of the chain.

Common characteristics

Public chains are often described as distributed, hard to rewrite, and inspectable. Many nodes keep the same history. Later blocks depend on earlier ones, which makes rewriting a healthy public chain costly. Confirmed transfers on a public chain can usually be inspected by anyone who reads that chain. Those properties belong to the network, not to a Fittyx order.

How the idea developed

Early public chains focused on digital cash and payments. Bitcoin is the best-known example: chained blocks, shared copies, and cryptographic signatures.

Later networks added programs that run on the chain, often called smart contracts. Ethereum is a well-known example. Many other networks exist, each with its own fees, confirmation times and rules. This article does not rank them and does not copy any whitepaper.

How this relates to Fittyx

Fittyx is a centralized exchange, not a public blockchain and not a DEX. Spot, perpetual futures, options and copy-trading orders are matched on the platform after you sign in. Those matches are not the same as appending a block on Bitcoin or Ethereum.

When you deposit a supported asset, the on-chain transfer goes to the address the platform shows. After the network confirms it, your Fittyx balance is the platform's ledger of what you can trade or withdraw. Withdrawals go back out on the network you select in the wallet.

Risk

Asset prices can move quickly. You can lose money. On-chain transfers are typically irreversible once confirmed. This article is not investment advice and is not a mining or node-operation guide.
