Introduction to the Ardor Platform

00:00 Ardor is a multi blockchain platform with a unique architecture that separates the network processing and security chain known as the Ardor parent chain.
00:16 On the transactional chains these transactional chains known as child chains have their own native coin for all transactions and thus don't require their users to have parent chain coins.
00:26 Being built on NXT technology, each child chain is pre fitted with the features found on the NXT blockchain, such as the ability to issue assets, trade them on an asset exchange, run public or private polls and set conditional transactions, set up multi-sig security or send encrypted messages, among many others, through a simple user interface as well as through a powerful API.
00:49 However, all transactions are still processed and secured by the parent chain.
00:55 This is facilitated with the help of the bundling system, where accounts can be set to collect transaction fees and child chain coins while paying the transaction fees to the parent chain in its own coin.
01:05 Since child processed by the parent chain, it's possible for the different chains to interact with each other, such as sending and receiving coins or assets from different child chains.
01:16 This allows for a great deal of interoperability among the different child chains, opening up even more potential use cases.
01:23 This unique architecture also enables Ardor to address one of the scalability issues found on every blockchain, known as the blockchain bloat problem.
01:31 This refers to the growing blockchain size as it gets used, thus making it more resource intensive to run a full node to support the blockchain network, as well as to join it.
01:42 Jelurida, the development team behind Ardor, addresses this problem by implementing full node pruning, where transactional data on child chains is regularly removed from the full nodes on the Ardor parent chain, after a snapshot is taken up at the most recent state, thus reducing the blockchain size without affecting the balances and ongoing transactions on each chain and the security of the whole platform.
02:02 However, full nodes can opt in to become archival nodes for specific child chains and store the historical data of these chains.
02:12 With all these benefits and features, as well as new ones continuously being developed by Jelurida, Ardor aims to be one of the top choices for companies and organizations to address their blockchain needs.
