Kaspa is the fastest and most scalable instant confirmation transaction layer ever built on a proof-of-work engine. Transactions sent to miners can be included immediately in the ledger, which is structured as a revolutionary blockDAG. Kaspa is based on the GhostDAG/PHANTOM protocol, a scalable generalization of the Nakamoto Consensus (Bitcoin consensus). Its design is faithful to the principles Satoshi embedded into Bitcoin - proof-of-work mining, UTXO-formed isolated state, deflationary monetary policy, no premine, and no central governance. Kaspa is unique in its ability to support high block rates while maintaining the level of security offered by the most secure proof-of-work environments. Kaspa’s current mainnet operates with one block per second. After the ongoing rust language rewrite, the core developers' goal is to increase the number of blocks per second substantially, attracting the development of smart contracts and DeFi.

The Reachability Oracle with Michael Sutton
The focus of this code walkthrough will be to get an understanding of Kaspa's DAG “reachability” layer.
The security of the Ghostdag protocol heavily relies on analyzing the connectivity of block subsets in order to identify the largest connected cluster which represents the honest majority. Throughout this search, the most fundamental question asked is whether two blocks have knowledge of each other, i.e., is there a path of DAG edges from one to another. We call this a reachability query.
Answering hundreds if not thousands of such queries per second with an ever-growing and dynamic DAG structure is anything but an easy task. Designing it in such a way that it can easily withstand 10BPS or more is a technology marvel I'm proud of being a significant part of.

Questions Asked in Chat
01:09:44:55 - 01:09:57:49
[Chat: is the reachability service "only" used when
blocks are added to DAG or even during other operations
(like querying DAG data, etc)?]
01:28:04:31 - 01:28:13:38
[Chat: when are you using delete_block?]
01:29:23:21 - 01:29:54:03
[Chat: If a majority hashrate attacker would withhold blocks up to some depth (lower than the usual reindex root depth), and then broadcast all their blocks at once (which should 2x at least the current set) how does this affect reachability intervals? What happens when blocks for a deep reorg suddenly appear]
01:31:22:02 - 01:31:35:23
[Chat: does it mean DAG reachability structure only contains the last three days blocks?]
01:36:13:33 - 01:36:26:34
[Chat: What happens to reachability queries when a reindex is occurring?]
01:39:35:27 - 01:39:49:36
[Chat: So during a reindex, is it possible that you may get an incorrect result for reachability? Since the current block being added wouldn’t be present in any current reachability interval yet]
01:49:25:26 - 01:49:38:13
[Chat: From my understanding, VSPC is a chain not tree, is the tree we talked about here the combination of (selected parent chain) for all the tips(not virtual)?]

tell me better why there are no transactions for the first half of the year
Such a cool and sexy soundtrack. It should be in every night club 🔥🔥🔥👍👍👍
That hurts me to have discovered Kaspa only 1 months ago
The sound is terrible 🥹🥹
300,000 active users and counting! BlockDAG is setting new standards!
I can't connect via KDX wallet to blockchain why? Do I need to do something or is the KDX wallet still working?
Great technology for ever🙏

Can you please purchase a high-quality microphone before the next time you post a video? you have a low quality microphone that has an echo and cuts in and out. So it’s too frustrating to listen.
Best Team ever
Is it possible to send kaspa from one wallet to another without Internet?
KASPA is definitely the KING and the launch of the KASPA rocket will definitely be fast

First Blockdag! 🎉🎉🎉
Amazing tech & great investment for early investors. Too bad its in crypto market & not tech stocks.
Good job 👏🏼
amazing job!! congrats!!!
if you guys are the devs and accumalted a lot of KAS early on, why don't you pool together your kaspa for a listing on coinbase and binance?
Because when you pay for listings... Exchanges dump on you to make quick money, they are not our friends and it's a fair launched project after all... Things are going slowly but even compared to BTC, the all time chart looks amazing. Patience brother, DCA and HODL. Great things are coming.
Coinbase and Binance both claim that they do not charge money for listings, they list coins based on a very strict criteria. Don't fret, a Binance listing is in the very near future. End of January/beginning of February. Bookmark this video and yell at me if it doesn't happen. But thank me when it does.
You could donate your coins as well!
@@BlueBacon1111true, there are initiatives for that! "Don't ask what Kaspa can do for you - ask what you can do for Kaspa" 🙂
I am always amazed when I read comments like that. I see it a lot with the people new to crypto. It's almost as if they watch some TH-cam video with their favorite crypto "influencer" (most are scammers that take advantage of these beginners), then THEY make the decision to invest THEIR money into a project, and then believe somewhere in their little brain that the devs now work for them...that the devs should not only spend their time, but also their money to protect these people's investment. It's a level of entitlement that, unfortunately, I'm starting to get accustomed to seeing in the crypto space.

Congrats kaspa team. The best.
Amazing kaspa technology, the only great coin i know 💚
