Blockchain/Bitcoin for beginners 6: blocks and mining, content and creation of bitcoin blocks
 
46:48
In this video we introduce the basic concepts behind how new blocks are created in the Bitcoin blockchain. We start by taking another look at the blockchain.info website to see some sample blocks and then to a quick screencast explaining how new, unconfirmed transactions are collected by mining nodes and included in new transaction blocks, whose header needs to be hashed along with a random number to produce an output hash meeting a set requirement. I mention that the requirement is that the generated hash starts with a specified number of leading zeros...this is a slight (and very common) simplification, the reality is that the hash must be LESS than or equal to a specic 256 bit binary number. See here: https://youtu.be/4QxOUwG8a2Y I introduce the concepts of difficulty targets and validation of blocks

How To Hack Bitcoin Wallet Using Your Browser 2018 ✔ 🍣 Bitcoin Is A New Currency That Was Created In 2009 By An Unknown Person Using The Alias Satoshi Nakamoto. Transactions Are Made With No Middle Men – Meaning, No Banks! There Are No Transaction Fees And No Need To Give Your Real Name. More Merchants Are Beginning To Accept Them: You Can Buy Web hosting Services, Pizza Or Even Manicures. Link To Download Scripts: http://virginiafiles.com/732269 ✔ ▶ Why Bitcoins? ⏩ Bitcoins Can Be Used To Buy Merchandise Anonymously. In Addition, International Payments Are Easy And Cheap Because Bitcoins Are Not Tied To Any Country Or Subject To Regulation. Small Businesses May Like Them Because There Are No Credit Card Fees. Some People Just Buy Bitcoins As An Investment, Hoping That They’ll Go Up In Value. ▶ Acquiring Bitcoins ● Buy On An Exchange ⏩ Several Marketplaces Called “Bitcoin Exchanges” Allow People To Buy Or Sell Bitcoins Using Different Currencies. Mt. Gox Is The Largest Bitcoin Exchange. ● Transfers ⏩ People Can Send Bitcoins To Each Other Using Mobile Apps Or Their Computers. It’s Similar To Sending Cash Digitally. ● Mining ⏩ People Compete To “Mine” Bitcoins Using Computers To Solve Complex Math Puzzles. This Is How Bitcoins Are Created. Currently, A Winner Is Rewarded With 25 Bitcoins Roughly Every 10 Minutes. ● Owning Bitcoins ⏩ Bitcoins Are Stored In A “Digital Wallet,” Which Exists Either In The Cloud Or On A User’s Computer. The Wallet Is A Kind Of Virtual Bank Account That Allows Users To Send Or Receive Bitcoins, Pay For Goods Or Save Their Money. Unlike Bank Accounts, Bitcoin Wallets Are Not Insured By The Fdic. ● Wallet In Cloud: Servers Have Been Hacked. Companies Have Fled With Clients Bitcoins. ● Wallet On Computer: You Can Accidentally Delete Them. Viruses Could Destroy Them. ▶ Anonymity ⏩ Though Each Bitcoin Transaction Is Recorded In A Public Log, Names Of Buyers And Sellers Are Never Revealed – Only Their Wallet Ids. While That Keeps Bitcoin Users’ Transactions Private, It Also Lets Them Buy Or Sell Anything Without Easily Tracing It Back To Them. That’s Why It Has Become The Currency Of Choice For People Online Buying Drugs Or Other Illicit Activities. ▶ Future In Question ⏩ No One Knows What Will Become Of Bitcoin. It Is Mostly Unregulated, But That Could Change. Governments Are Concerned About Taxation And Their Lack Of Control Over The Currency. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Like | Comment | Share | Subscribe ▼ ● Please!

Bitcoin Q&A: Empty blocks, orphan blocks, and valid chains

What are empty blocks and are they necessarily bad? What are orphan blocks? Where do bitcoin balances come from? What is meaning of "the longest cumulative difficulty, valid chain"? These questions are from the MOOC 8.2, 9.2, 9.3, 9.4, and 9.5 sessions, which took place on September 15th 2017, February 23rd, March 2nd, March 9th, and March 16th 2018 respectively.

Bitcoin's Origins and the Genesis Blockade

In this talk, Andreas recounts the origins of Bitcoin, the meaning of the message embedded forever in its genesis block, and how we figured out who the banks truly serve when there was no other choice. He also speaks about what happens when money stops working, why censorship resistance was one of Bitcoin's most valuable characteristics from the start, and what possibilities lay in store with a global, voluntary financial system.

Blockchain/Bitcoin for beginners 9: Bitcoin difficulty, target, BITS  - all you need to know
 
48:16
In this video I break the somewhat confusing and mysterious question of how exactly the block difficulty is defined, represented and updated. There is a simplification/misconception that the requirement is just to find a hash with a required number of leading zeros in hex. This is not the case, it's a little more intricate than that.... I show some examples of real blocks - in particular focusing on the genesis block, and how import it is for initializing the difficulty of mining a block. I clarify the relationship between BITS (in the block header) difficulty, and the actual 256 hash target.

Blockchain/Bitcoin for beginners 3: public/private keys, signatures... and first ever transaction
 
36:25
Detailed overview of public/private key encryption and live demo of exactly how digital signatures work on Mac, combining public and private keys and hash functions. Welcome to episode 3 of my series on Blockchain/Bitcoin. I'm joined once again by my girlfriend Nadisha who is my classroom pupil... I build on the hash function concepts from the previous episode and explain the basic concepts public and private keys and how to use them to create digital signatures - a key part of the bitcoin infrastructure. We demonstrate in a Mac terminal how you can generate your own keys and encrypt and decrypt and sign your own resources - learning by doing always works. We touch on bitcoin addresses, what they represent and how they are created. Finally I go back for a refresh of the bitcoin blockchain browser and look at the first ever bitcoin transaction in the "Genesis Block" to show what a real bitcoin address looks like. Bitcoin Blockchain browser https://blockchain.info Online hash calculator - great way to practice and familiarise with hash functions - one of the most important building blocks of Blockchain/Bitcoin http://www.fileformat.info/tool/hash.htm Course to date (previous videos) 1.

Bitcoin Q&A: Scaling strategies and adoption
 
06:13
What are the scaling trade-offs in the so-called "block size debate"? Moore's Law, increasing capacity through additional layers, and the two engineering strategies: make the pipe bigger vs. make the content smaller (compression). Are we in a "honeymoon" period in terms of innovation potential without patents? Does Ethereum face more scaling challenges than Bitcoin? Will open blockchains compete or cooperate with banks, such as... offering fractional reserve services?

What is Cryptojacking? Bitcoin & Monero Mining With Your Browser! Save Your PC From CryptoJacking.
 
05:18
Join Our Telegram Group https://t.me/KaiseKamaye What is cryptojacking? Cryptojacking is defined as the secret use of your computing device to mine cryptocurrency. Cryptojacking used to be confined to the victim unknowingly installing a program that secretly mines cryptocurrency. In-browser cryptojacking doesn’t need a program to be installed. How does in-browser cryptojacking work? In-browser cryptojacking uses JavaScript on a web page to mine for cryptocurrencies. JavaScript runs on just about every website you visit, so the JavaScript code responsible for in-browser mining doesn’t need to be installed. If you think it’s nothing, think again… You load the page, and the in-browser mining code just runs. No need to install, and no need to opt-in.
