Charli3

An open-sourced, decentralized network of oracles bringing off-chain data onto the Cardano blockchain using inter-node vetoing to ensure data accuracy.

On-chain smart contracts are used to connect to the external world and interface with off-chain data. The data gathered is aimed at the world of DeFi, yet oracles for other industries will be produced when the demand for them arrives. Clients can also request specific oracle data to support the off-chain computation of smart contracts.

Data Sources

Data sources are split into two categories, primary and secondary, with primary sources weighted more heavily than secondary sources. Primary sources include: decentralized and centralized exchanges and well established on-chain tools. Secondary sources are other oracle providers and it is this which makes Charli3 an oracle aggregator.

After validation data will be stored and reported via a partnered reverse oracle and made accessible to token holders via a subscription service.

Security

A council made up of representatives from participating nodes receive rewards, in the CHARLI3 token, for verifying data. These data providers and nodes are kept honest through the staking of tokens.

If an operator proves to be inaccurate then they lose a part of their stake, and it is transferred to accurate operators. This incentivizes honesty and inter-node auditing, through vetoing, and builds in a third party fail-safe to the protocol.

DAO

Tokens are used for both data consensus and for voting on proposed changes to the network. Larger stakes, often owned by nodes, are associated with a ELO-based reputation system, a gamified reputation system based on win, draws and losses against other participants in the system. Therefore, the most trustworthy nodes are rewarded with greater voting weight.

CH3 is currently live on Ethereum, after the project went through the CardStarter launchpad and accelerator. Once smart contracts are launched on the Cardano mainnet CardStarter will migrate the whole project to the Cardano blockchain. As a result of their relationship with CardStarter CHARLI3 will be the preferred and suggested oracle solution for all future CardStarter IDOs.

Oracle

In the ancient world oracles were people through whom the Gods spoke directly to the inhabitants of earth. In the blockchain and crypto world oracles are a service that provides off-chain data to smart contracts running on a blockchain.

On-chain functions, i.e. smart contracts, cannot access real world data on their own. This is problematic when a smart contract is trying to provide the real-time price of financial assets to users, or when it needs to determine the outcome of a sporting event for a gambling protocol, or even when it has been asked to use something measurable in the real world, such as the temperature or quantity of snowfall, in its calculations. Oracles can feed any real world data onto the blockchain for use by smart contracts.

Data is collect it in a variety of ways: APIs, websites, sensors, etc, and can be manual input by humans. This data is collect by nodes and is then passed on to the oracle service that then supplies the smart contract with the data. Having one node supplying data means a central point of failure, and a high potential for manipulation of the data. As a result oracle services usually use a network of nodes to build a consensus of the correct data point and to prevent the data from being manipulated, thereby helping to ensure trust in the data they supply.

On-Chain

These are all the on-chain NFTs, and on-chain NFT collections, that currently exist on Cardano. Many people consider on-chain NFTs to be better, or more special, than off-chain NFTs.

In regards to the on-chain vs off-chain NFT argument, the image represented by an off-chain NFT is found by following a link, typically stored on the IPFS, from the NFTs metadata. This can be changed by the person who uploaded it. The image represented by an on-chain NFT is coded into the metadata and is, therefore, immutably coded into the blockchain's history. This is usually, but not always, in the form a language that your browser understands, allowing your browser to interpret that information and display the NFT.

Launchpad

The term launchpad is often used in the same sentence as the terms incubator and accelerator, but the three have their own subtle differences. Many launchpads also operate an accelerator and/or an incubator. But what does a launchpad do?

A launchpad connects new projects to investors, and allows the project to raise funds by giving investors access to an exclusive, early, and often discounted, token sale. So the project gets the funds in needs to proceed with development and investors get tokens at a discounted rate before they’ve even hit the market. To offer security to their investors, and to uphold their name, launchpads will conduct through KYC into the projects applying to be on their launchpad.

Some launchpads will also offer many of the same services offered by incubators to the fledgling projects that conduct token sales through them.

Launchpads are often a sidearm of an exchange, of both the centralized or decentralized varieties, as they already have the capacity to sell tokens and can then offer a guaranteed place for the tokens to be listed once the project is ready to release them to the public.

DeFi

Here are all the Cardano DeFi projects complete with descriptions and tags. If you’re looking for a Cardano DeFi exchange, a lending protocol, a launchpad, a Cardano stablecoin, or platforms on which to tokenize real world assets then you’ve come to the right place. The Cardano DeFi ecosystem is maturing and, as it does, we will continue to list the new Cardano DeFi projects here. If you look at Cardano in 5 years this list will be substantially different, some projects will have left it, but many many more will have been added.

If you’re looking to simply swap Cardano native tokens then a Cardano DEX is your best choice. If you’re looking to utilize your crypto holdings for a loan then take a look at all the Cardano lending and borrowing platforms on offer and choose which one fits your needs. There is much more utility in the Cardano DeFi world and we invite you to explore it here!

DAO

If a project on Cardano operates with a DAO that you’ll find it tagged and listed on this page. All of these Cardano DAO projects have, in some form or another, incorporated or plan to incorporate a DAO. Not all of them will be full autonomous and this may be for one of many reasons, be it that features are being released gradually, that they will never actually be a full and proper DAO (and this a debate for another time).

There are specific Cardano DAO projects listed here, and these are those that operate as a full DAO, who’s direction is guided by the votes of its members. Others on here are projects and protocols built on Cardano, and these can take various forms, including: DeFi projects, NFT projects, and gaming projects.

Regarding full Cardano DAO projects, these have been created around many different topics, the most popular being Cardano investment DAOs that invest in Cardano NFTs and tokens. However, there are other DAOs focused around things such as the development of open-sourced tooling, the growth of the DAO idea itself, and art.

Audit

Audits are incredibly important in the decentralized and blockchain world and audits are completed on a platforms code, typically by 3rd parties, to ensure that that code is as watertight as possible. Conducting audits before releasing product is a best practice technique and can expose flaws in a protocol before that protocol is released to the public, allowing developers to fix them so that they cannot be exploited by hackers.

When we run on the mantra that “Code is law” then that code needs to be secure so that everyone can be sure that their tokens are safe in the protocols and platforms they’re using. The projects tagged with audit are those that offer or conduct audits on platforms and projects in this space.

Aggregator

An aggregator is a person or entity who gathers things together and then either displays them to others or utilizes what they have gathered for a purpose.

The most common use case for aggregators in the blockchain world is a DeFi protocol that aggregates DEXs. This means that a user submits their order to the aggregator protocol and the protocol distributes that order across multiple DEXs to get the user the best price at the lowest cost.

Accelerator

The term accelerator is often used in the same sentence as the terms launchpad and incubator, but the three have their own subtle differences. Many accelerators also operate a launchpad and/or incubator to help them progress the projects they are accelerating.

An accelerator is a business or organization that supports existing early-stage businesses (often business that are yet to earn any revenue) by accelerating the growth of their product. Accelerators often focus on a certain niche or sector, e.g. finance, and also mentor the businesses that they take on. Accelerator can sometimes offer finical assistance to the juvenile businesses that they take on. These businesses must apply to be a part of the accelerator and the accelerator then accepts or rejects their applications.
