Harmony is a layer-1 blockchain using sharding and Effective Proof of Stake to achieve scalability, security, and decentralization. The network was launched in 2019 and features trustless cross-chain bridges and four shards, which process transactions in parallel. Effective Proof of Stake encourages decentralization of validators, and sharding shares the network's load among validators, delegators, and users.

BUSD is a regulated, fiat-backed stablecoin pegged to the U.S. dollar. For every unit of BUSD, there is one U.S. dollar held in reserve. In other words, the supply of BUSD is pegged to the U.S. dollar at a 1:1 ratio. Holders can swap their tokens for fiat and vice versa. Paxos, the token’s issuer, releases monthly attestations of BUSD’s reserves.

Decentraland is a virtual world and community based on blockchain technology. Users develop and own plots of land, artwork, and Non-Fungible Tokens (NFT). Members also participate in the platform’s Decentralized Autonomous Organization (DAO).

Avalanche attempts to improve scalability without compromising speed or decentralization. Three blockchains make up its core platform - the Exchange Chain (X-Chain), Contract Chain (C-Chain), and Platform Chain (P-Chain). The X-Chain is used for creating and trading assets. The C-Chain is for smart contract creation. The P-Chain is for coordinating validators and Subnets.

A wrapped token is a cryptocurrency token pegged to the value of another crypto. It’s called a wrapped token because the original asset is put in a wrapper, a kind of digital vault that allows the wrapped version to be created on another blockchain.

A stablecoin is a cryptoasset pegged to another asset, such as fiat currencies or precious metals. Stablecoins are designed to maintain a relatively stable price so that users can avoid the volatility risks common in the crypto markets.

Tokenized Bitcoin is a way to use bitcoin on other blockchains. But wait, isn’t Bitcoin great already? Indeed it is! It has a solid use case, and it already acts as a kind of public good. At the same time, its purposely limited features leave little room for further innovation.
