Who governs Tagion?

The users of the system by a reputational trust score model and Proof of Community model.

More, we are trying to extend the governance model to reward all actors in the model, which could be divided into four main categories:

  • Sense-makers: core concept developers
  • Value-makers: programmers and nodes
  • Relation makers: evangelists and services on top
  • Decision-makers: core developers and node operators
What is a DEX?

A DEX is a decentralized exchange that allows people to place orders and trade cryptocurrencies without an intermediary institution managing the ledger or controlling user funds. Close to all DEX however don’t have a pair matching due to the lack of consensus ordering. Also, even though the exchange itself is decentralized the matching is still centralized (may be open-source in some cases though).

Does Tagion have a DEX?

Yes - soon. Pay with anything anywhere. Tagion DEX is an open protocol that enables a trustless exchange of any digital currency that supports HTLC (Hash Time-Locked Contract). Thanks to the fair ordering of transactions enabled by Hashgraph, Tagion DEX also provides automatic ‘on-chain’ pair matching.

Once completed, Tagion’s DEX will be able to seamlessly exchange between all common crypto and FIAT currencies (semi-decentralized). Read more in the White Paper.

Is Tagion open-source?

We have currently open-sourced 5 libraries, you can found them on Tagion GitHub.

Eventually, all Tagion modules will be open-sourced.

What is DART (Distributed Archive of Random Transactions)?

DART (Distributed Archive of Random Transactions) is built to store and keep track of transactions in the Tagion network. The database efficiently handles the removal and addition of transactions in a secure and distributed manner.

Why is DART better than Legacy or other distributed databases?

In comparison to other distributed ledger technologies, DART is optimized for token transfers. It creates cryptographic bills which makes it extremely efficient for searching, reading and storing. It also contains a fingerprint for the state of the database, another feature that is missing in classic distributed hash tables.

What is HTLC (Hash Time Locked Contract)?

A Hashed Timelock Contract (HTLC) is a type of smart contract used in cryptocurrency channels to eliminate counterparty risk. It enables the implementation of time-bound transactions.

In practical terms, this means that recipients of a transaction have to acknowledge payment by generating cryptographic proof within a certain timeframe. Otherwise, the transaction does not take place.
