Blockchain concepts

Let’s review some concepts related to blockchain.

Difference between an “asset first” wallet and a “network first” wallet

  • An asset-first wallet is primarily designed to manage specific cryptocurrencies or tokens. These wallets are usually optimized for a particular blockchain network or a set of networks, and they offer features that are tailored to the specific assets they support. Asset-first wallets may have limitations on the types of cryptocurrencies they can hold or the number of assets they can manage, but they are typically more user-friendly and easier to navigate for users who are primarily interested in managing their assets.
  • A network-first wallet is designed to be more flexible and agnostic to specific assets. These wallets are optimized for managing a wider range of cryptocurrencies and tokens across different blockchain networks. They may have more advanced features, such as support for decentralized exchanges or other decentralized finance (DeFi) protocols, but may also be more complex and less intuitive for users who are less familiar with the intricacies of different blockchain networks.

Examples asset-First Wallets:

  • MyEtherWallet (MEW) – MEW is an asset-first wallet that is optimized for managing Ethereum-based tokens, such as ERC-20 tokens. It provides a simple and user-friendly interface for managing Ethereum assets, and also supports integration with hardware wallets for enhanced security.
  • Ledger Nano S – The Ledger Nano S is a hardware wallet that is primarily designed to store cryptocurrencies, such as Bitcoin and Ethereum. It supports a wide range of cryptocurrencies and tokens, and provides advanced security features such as two-factor authentication and a secure element chip.

Examples of Network-First Wallets:

  • MetaMask – MetaMask is a network-first wallet that supports a wide range of blockchain networks, including Ethereum, Binance Smart Chain, and Polygon. It provides a user-friendly interface for managing different assets across multiple networks, and also supports integration with DeFi protocols.
  • Trust Wallet – Trust Wallet is another network-first wallet that supports multiple blockchain networks, including Ethereum, Binance Smart Chain, and Polkadot. It provides a simple and intuitive interface for managing different assets across different networks, and also supports staking and other DeFi features.

What is a parachain?

A parachain is a blockchain that operates in parallel to a main blockchain, also known as a relay chain. Parachains are typically designed to provide additional functionality or specialized services that are not available on the main blockchain.

  • Parachains are connected to the main blockchain (parachain leasing), where they lease a slot on the relay chain to be able to participate in the overall network. This enables the parachain to benefit from the security and consensus mechanisms of the main blockchain.
  • Parachains functionalities could be:
    • Support for specific smart contract languages,
    • Privacy features, or specialized token economics.
    • Provide scalability improvements by processing transactions in parallel to the main blockchain, which can help to reduce network congestion and lower transaction fees.
  • Parachains are a key feature of the Polkadot network, which is designed to enable interoperability between different blockchains and provide a scalable and secure infrastructure for building decentralized applications.

what is Fiat Onramps?

It’s the mechanisms or services that allow individuals to convert fiat currency (such as US dollars or euros) into cryptocurrency. In other words, it is the process of purchasing cryptocurrency with traditional fiat money.

Fiat onramps can take various forms, the more commons are:

  • Cryptocurrency exchanges
  • Peer-to-peer marketplaces, or brokerages.

These platforms typically require users to link a bank account or credit card to their account and go through a verification process to comply with anti-money laundering (AML) and know-your-customer (KYC) regulations.

Fiat onramps play a crucial role in the adoption and use of cryptocurrencies, as they provide an easy and accessible way for individuals to acquire cryptocurrency without having to mine it or trade it directly with other users. They also allow individuals to convert their cryptocurrency holdings back into fiat currency when needed, providing liquidity and stability to the market.

Many cryptocurrency exchanges offer fiat onramps as a key feature, and some have even partnered with traditional financial institutions to facilitate the conversion of fiat to cryptocurrency and vice versa. However, it’s important to note that not all cryptocurrency exchanges offer fiat onramps, and that the availability of these services may depend on the user’s country of residence and the specific regulations governing cryptocurrency transactions in that jurisdiction.
