Hosted wallets are digital cryptocurrency wallets provided by trusted third parties that keep users’ private keys and funds safe. These third parties are usually cryptocurrency exchanges. Coinbase and Binance are two well-known examples. Hosted wallets share similarities with centralized banking applications because they leverage two-factor authentication and password recovery. They are also custodial, meaning that users don’t retain control of their private keys. Less experienced traders often choose them as they are easy to set up and use. In addition, traders who regularly operate on centralized exchanges may opt for hosted wallets.
Secure multi-party computing (SMPC) allows a network to compute data in a secure manner. SMPC is a trust-free- free mechanism for encrypted data delivery in which inputs, despite their secrecy, it remain highly usable. The input data is divided into pieces. Without decryption, coded functions can later aggregate and analyze these pieces. Because SMPC has "no single point of trust," one computing party cannot have unilateral control over input data. Peers on a network can use SMPC for a variety of functions, including the construction of secure data models and voting. Furthermore, SMPC has a variety of applications in the cryptosphere. To increase security, crypto wallets and exchanges utilize a variant of SMPC known as a Threshold Signature Scheme (TSS) to divide private keys into pieces and spread them across many nodes.
Proof of Stake is a form of the blockchain consensus process. It chooses validators at random from the network using a probability method proportionate to the validators' holdings in the blockchain's native coin. After the computation is performed, the validating node is paid with transaction fees. The Proof of Stake method was developed as an alternative to the Proof of Work mechanism, which lacks scalability because of its energy-intensive nature and the requirement for miners to compete with elite hardware to validate blocks. Some consider Proof of Stake to be a more secure paradigm since it reduces miners' incentives to attack networks. A validator loses some of its stakes if they verify false transactions.
Peer-to-peer networks are made up of several nodes that create a distributed architecture. Tasks are distributed among peers, each of whom has an equal status on the network. Node-to-node networks disperse requirements such as processing power and storage, eliminating the need for centralized coordination. Peers, as opposed to more typical client-server architectures, act as both suppliers and consumers of resources. Unstructured, structured, or mixed peer-to-peer networks are all possible.
Layer-2 is a secondary structure that is created on top of a layer-1 blockchain. Layer-2 solutions are used by developers to boost throughput by remote-sourcing activities from the layer-1 blockchain. Third-party layer-2 solutions are frequently developed to complete tasks independently of the layer-1 blockchain. Because of this isolation, layer-2 solutions are sometimes referred to as "off-chain." Layer-2 systems, on the other hand, rely on the layer-1 blockchain's security and decentralization. The "scalability trilemma," which states that enhanced layer-1 scalability diminishes security and decentralisation, is resolved by layer-2 solutions. Layer-2 solutions that are commonly used include state channels and hierarchical blockchains.
Immutable X is the first Layer-2 solution that is only dedicated on scaling Ethereum-based non-fungible tokens (NFTs). The necessity for scalable, rapid, and affordable NFT markets cannot be stressed enough as NFTs expand in the decentralized gaming and metaverse space. Immutable X may provide a feasible alternative for game creators wishing to mint millions of NFTs as in-game assets: no gas fees, instantaneous transactions, and all the security of the underlying Ethereum network owing to zk-Rollup technology.
