Built on Ethereum
There are many different types of applications that can be built on Ethereum. Most applications today fall into the following categories.
Decentralized finance refers to a number of decentralized protocols building open financial infrastructure. These protocols are valuable because they're creating the necessary plumbing to enable anyone in the world with an internet connection to access self-sovereign, censorship resistant financial services.
Oracles refers to a protocols or services to connect Ethereum to offchain information. They can be utilized for querying information from the internet (e.g. API calls), information about other chains (e.g. BTC transactions), or even as dispute resolution mechanisms concerning non-native assets.
Decentralized Exchanges allow for the trading of crypto assets without the need for a trusted central authority. This cuts down on the risk of exchange hacks and many other risks. There are many types of decentralized exchanges and it's important to understand the differences.
Blockchain games are any games that include blockchain technology in its backend or mechanics in general.
Crypto collectibles are unique items that adhere to the ERC-721 standard. They can be collected and perhaps used across many different games and applications built on Ethereum.
Marketplaces built on Ethereum allow for the trading of ERC-721 tokens such as crypto collectibles.
A suite of developer tools allow for better standards and easy implementation of these standards across many different applications.
Identity is a very important aspect to the future of Ethereum. The Ethereum network hosts many DApps that are building identity systems. These DApps leverage the secure and decentralized nature of the Ethereum network often in collaboration with decentralized storage protocols such as IPFS or SWARM to enable empower and protect consumers' information. Citizens will be able to confidentionally reveal personal information such as Gov. ID, credit score, medical history, banking information, etc. to others in a way that also allows them to revoke future access to such information.
Given the decentralized nature of the protocol, it’s important for some applications to have a way to govern their team, project or app.
Building out basic infrastructure needs using Ethereum as a base layer.
Token Curated Registries
Token Curated Registries are registries of listings generated by token holders. Listings can be anything from names to hashes of full-blown records stored in IPFS.
ERC Token Standards
ERC Token Standards are technical documents used by smart contract developers at Ethereum. They define a set of rules required to implement tokens for the Ethereum ecosystem.
