Blockademia

Using the Cardano blockchain to issue immutable proofs for documents that can then be use to verify said documents' authenticity.

Using a web application institutions, governments, corporations, and anyone else who wants to will be able to issue documents with an attached proof of authenticity that is verifiable through the Cardano blockchain. Then, using an Android or iOS applications, anyone will be able to scan the QR code generated by the authentication procedure to confirm the authenticity of said document.

How it Works

A user, a university for example, will upload a digital version of the certificate they want to issue on the blockchain. The Blockademia web application then creates a hash from this document and sends that hash to the blockchain as transaction metadata. A QR code is generated that is uniquely tied to the blockchain verification of that document.

Someone looking to verify that document will then scan the QR code using the mobile app. If the QR code is a true code it will return with information about the verified document, such as: which institution issued it, who it was issued to, when it was issued, etc. This can then be compared to the physical copy of the document to confirm that it is authentic and not a forgery.

Different User Levels

There are four different levels of user depending on the needs of the individual or institution. These levels are obtained by staking the applications native token, ACI. The token requirement varies from 1000 to 50,000 depending on which level of tools the user wants or requires. The required holding amount for each user level will decrease in correlation with the growth of active document issuers on the platform in order to continue to make it accessible to new document issuers.

ACI Token Functions

These tokens have more utility than simply staking. They are also required for:

Paying fees on the platform
Rewarding successful referrals: with a one time payment and a lifetime percentage of the referred’s transactions
Treasury financing
Governance

Tokens can be locked to earn additional yields of 10% per year, in ACI tokens, and locking tokens grants access to some, yet to be defined, advanced functionalities of the system. It does not say what these yields are given in addition to as there is no mention of yields elsewhere in Blockademia's documentation.

When Cardano enters Voltaire Blockademia will transition to being completely community governed through a DAO funded by a treasury

Each transaction competed on the network needs to be paid for in ACI, and this is redistributed with the majority, 65%, going to the “manager”. Currently this is the entity that owns Blockademia but, in the long term, it is said to be "the community". This is assumed, but not implied or stated, to be the DAO treasury.

Metadata

Metadata is an element of a Cardano transaction that can be inputed by the user or automatically generated. It is stored on the blockchain with the transaction that it was sent with. This means that, just like the transactions themselves, metadata is immutable, i.e. unchangeable, and stored forever on the Cardano blockchain.

Anyone can add metadata into a transaction and that metadata is then stored on the blockchain. Many wallets allow you to add custom metadata to a transaction.

Metadata can only be made up of characters i.e. numbers, letters and punctuation, and cannot be a file type, i.e. you cannot unload files like PDFs or MP3s to the blockchain. The size of the metadata you can add to a transactions is limited to 16KB, and a character is, typically, 1 Byte, so that means you can add up to 1600 characters as metadata with any transaction.

Metadata can be used for many purposes the most common is to give some form of context to the transaction. Metadata has been used to store supply chain data, to send arbitrary message to be stored on the blockchain, and to store the hash of a document (allowing the blockchain to be used for proof-of-existence). People have used metadata, on the testnet, to immortalize the Cardano whitepaper, by writing it onto the blockchain as transactions across multiple transactions.

Many block explorers allow users to view and search transaction metadata. Remember, anything you add as metadata to a transaction will always be publicly available on the blockchain.

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.
