• 50:22 Resumo Consensus algorithms and proof of work Pedro Lucas Proof of something at play to win or lose or that gives you some interest in that Cardano survives and is healthy. Okay, so actually I left the scheduling part for the proof of stake bit because on proof of work that's not so valid. Proof of work can be described as proof of effort. And so the machi bitcoin · block · blockchain · consensus · ledger · proof of stake
• 57:27 Discussão Consensus algorithms and proof of work Amiar (gekkido) You didn't lose your look as. But I did study the consensus algorithms for some months in detail. And I would. There's things I would like to argue, but in a different. Maybe in a different context, like which is the best algorithm of consensus, etc. bitcoin · block · consensus · hash
• 39:00 Conceitos Blocks, blockchain, nodes, and stake pools Pedro Lucas So we're going to go straight from the simple thing that you touch on all the way to what happens in the blockchain, what are the block producers and all that thing including the consensus algorithm. So let's fly over this. I just had to fill in these three gaps here. So yeah, so now this, the block block · blockchain · consensus
• 0:30 Discussão Introductions and participant interests Priyansh Rai Then I switched like I started loving the concept of the blockchain and bitcoin and in that I have also learned some technical things about Web 3.0 and then I came to Cardano and here I find that there is less awareness in this chain currently. But this. All these communities and these people. Yep. bitcoin · blockchain
• 28:53 Resumo Wallets, keys, addresses, and transactions Pedro Lucas This is what give people what you give people so they can pay you. Sharing it is harmless and the worst cost you is a little privacy because as you've seen in the Cardano blockchain, anyone that has your address can inspect what you have in your wallet and move back in your movements even in time. S blockchain · ledger
• 43:14 Discussão Blocks, blockchain, nodes, and stake pools Pedro Lucas One thing interesting is that each stake pool needs to have one machine that's a block producer and two other nodes that are working in teams with the block producer, just to echo the information around again so that the network is more resilient, more resistant to, you know, one of them being down. block · trust

• 14:34 Conceitos Testnet Wallet and Transaction Demonstration Pedro Lucas So if I opened this again, if we go back to our stickies, the third sticky that I have here besides doing some transactions is Block Explorers. So what is this thing? Block Explorer. If we go to Google and just say Cardano Block Explorer and I think I mentioned on the last session that the blockchai bitcoin · block · blockchain · hash
• 39:29 Resumo Self-Custody and Wallet Security Pedro Lucas What happened, for example, recently is, is that I did do the transaction to Binance or to an alternative to Binance, and they just said, oh, we're too busy now, we can't really process your deposits. And I was left like, okay, so you're the bridge between the blockchain and my traditional bank. And bitcoin · block · blockchain
• 29:50 Conceitos Cardano Assets and Token Caution Pedro Lucas So the main coin on Cardano, the one that I can trust, was issued by the chain itself. You know, these ones on the small, on the, on the bottom part, these were created by people. And anyone can create any token on the Cardano blockchain. But this one ADA is the coin that I know the blockchain is is blockchain · trust
• 36:44 Resumo Self-Custody and Wallet Security Pedro Lucas Why do we call this kind of wallets self custody? And the reason is that we have this, which is what we've been talking about, which is pure blockchain working. It's just our device communicating with this blue cloud, which is a blockchain. And the only things that circulate here are bitcoin, ada et bitcoin · blockchain
• 52:36 Discussão Cardano Applications and Learning Resources Pedro Lucas ADA allows you. Let me just add a note here. Yo, this is really big with ada. You can decide who produces blocks for the chain for the blockchain. And that's what you do when you are staking your ada. You're saying, I trust this person to produce blocks. Staking is saying I trust this person to prod blockchain · trust
• 57:44 Resumo Mainnet, Staking, and Bitcoin Wallets Pedro Lucas Chichi was asking Vesper for now only communicates with the Cardano blockchain and I wanted you to try something from this side because unlike Vesper where Vesper you see all the tokens and all those little things. Bitcoin is uninteresting to the point that you just see I have this amount and this i bitcoin · blockchain
• 1:07:05 Alargado Practice and Learner Questions Chinyere Uchendu Okay so okay, sorry, I have a question. Right so now right? Just like we have bitcoin, we have either right? And both of them can perform the same thing like similar things but just they are on different. What's the, the word? Blockchain. Exactly. bitcoin · blockchain
• 1:09:02 Conceitos Practice and Learner Questions Pedro Lucas And that's it. So it's the network that pays them. And here it's also the network that pays them, but we call them block producers get rewarded by the Cardano blockchain for producing blocks on behalf of ADA holders. block · blockchain

• 13:20 Resumo UTXO Model Explained Pedro Lucas And so what we're talking about, when we talk about proof of work, we're talking about how do these machines compete and decide like what's the score to see who gets to produce the next block on Cardano that happens because having ADA gives you legitimacy, gives you the right to produce blocks. Okay bitcoin · block · consensus · hash · proof of stake
• 44:27 Resumo Transaction Submission Flow Pedro Lucas But just keep in mind that when the applications decide on moving something in the blockchain, there needs to be a signature on a transaction and it needs to be routed either through the mobile app to the back end app to the data provider or, I don't know, some kind of way of submitting that transac block · blockchain · proof of stake
• 1:14:03 Conceitos Oracle Function Explained Pedro Lucas So we need to trust these entities to throw in as metadata or as something into transactions so that the information of how much rain did it have, that did we have in certain location to come onto the blockchain. And then I can trust that the smart contract is going to look at that information, it's blockchain · trust

• 1:32:10 Conceitos Grant Thornton, Reeve and blockchain-based financial reporting Pedro Lucas Sorry. So securing Toast Trust in financial reporting. This is what the other showcase was talking about. This is what they do. And so this is a product to deliver verifiable and immutable insights on the Cardano blockchain. So verifiable and immutable is the kind of properties that are provided by blockchain · immutable · trust
• 1:34:48 Resumo Grant Thornton, Reeve and blockchain-based financial reporting Pedro Lucas When we look, for example, at edi, which is a decentralization, decentralization index that was Produced by Edinburgh. It has some ties with Cardano. So, yeah, there's that caveat. But I think the. The scientific work they did speaks for itself. Stands on its own, I think is the expression. When you blockchain · immutable
• 33:28 Discussão Wallets, networks and blockchain fundamentals Pedro Lucas So now you've covered that and you don't have any questions about like sending and receiving and seeing the history. Did you understand the part about the block explorer? Yeah, yeah, that makes sense. Right? Because you know, blockchain is a cloud of information. Anyone can access it from. From diff block · blockchain
• 39:08 Resumo Wallets, networks and blockchain fundamentals Pedro Lucas I also invited, I'm just going through my notes. I also invited your colleagues to install this other wallet which is not Cardano, it's Bitcoin. But it's just to give you already some cross chain understanding and understanding that there are different apps that communicate with different networks f bitcoin · blockchain
• 1:39:34 Conceitos Grant Thornton, Reeve and blockchain-based financial reporting Pedro Lucas It has a fingerprint which is a hash. And then if I scroll down, I see some tabs here we see the inputs and outputs that we saw on the previous sessions with me, these don't really matter for this transaction because what we want to look at is the metadata. And if you see here, you see Cardano Found blockchain · hash

• 13:43 Resumo Opening, Orientation and Participant Check-in Pedro Lucas So the first exercise we do in our sessions is putting ourselves in the perspective of people that never really heard about anything. And 45B usually focuses on real world use cases, not crypto necessarily. So we have this little diagram on a high level that we use to explain to people that crypto i bitcoin · blockchain
• 21:56 Resumo Web3, Web2 and Real-World Use Cases Pedro Lucas So we at 45B, we usually almost start with this kind of illustration of how based on bitcoin we got blockchain. And then out of this there's a number of things that are written on blockchains, but they are very different. So my question is, do you think there's a lot of things missing from here? Or bitcoin · blockchain
• 42:32 Resumo Money, Bitcoin and Digital Materials Pedro Lucas So I'm just putting in perspective when were talking about scams and crypto and all that sometimes there are similarities between fiat currency and scam coins. I'm not going to go over this too much, but I just wanted touch a bit on this difference. Let's just finish this part. So acceptability is s bitcoin · blockchain

• 25:43 Conceitos Web3 architecture: data, logic and application layers Pedro Lucas It's only when these blockchain nodes start sharing with each other that there's this new signed check by you that your transaction becomes persistent in a block and that block eventually is attached to the blockchain forever. Guys, this was a very long rant. I really want some feedback. Is this all block · blockchain
• 38:42 Discussão Web3 components, oracles and value creation Tevo Kask Haven't needed to think about this. A few months ago I had a dinner and I was asked, okay, so what good does blockchain do that we. Cannot have right now? And it was a energy company and said like, well, I don't know, actually. I think, I guess there is nothing. You can, you can't do that blockchain blockchain · trust
