Blockchain tutorial 27: Bitcoin raw transaction and transaction id
This is part 27 of the Blockchain tutorial. This tutorial explains: - What Bitcoin raw transaction is. - Shows an example of a raw transaction using the very first transaction on the Genesis block. - What the difference is between big endian and little endian. - What a satoshi is. - What a Bitcoin transaction id or hash is and what its purpose is. - How to calculate the transaction id. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

How to Build a Blockchain
Let’s look at how to build a blockchain. Blockchain is used by the cryptocurrency Bitcoin. Although Bitcoin’s price has been growing rapidly, Bitcoin is a very volatile investment. The incentives that blockchain brings to Bitcoin is that blockchain allows for a decentralized collection of data whose integrity is easily verifiable, and the data itself is immutable. In this tutorial, we are going to look at how to build a blockchain using JavaScript. You could also build a blockchain in python or java.

Blockchain Security Tools
Introduction Basic blockchain architecture as it pertains to block creation and consensus mechanisms is very sound. The algorithms used to accomplish the cryptographic functions might be questionable. Hence special consideration should be given to key management, key length, hashing algorithms, and the environment that activity is conducted in. To date none of the block chains have been hacked or maliciously modified, hence from that aspect we are safe. If you consider blockchain mechanisms to be the foundation, which are unhackable at this point, the next few layers above is where the problems start. In this show, I talk about various blockchain security tools currently available. Basic Blockchain Eco system The illustration below depicts the different layers that in my opinion comprise a blockchain eco system. Layer 1: Consensus and Cryptographic functions. Layer 2: Virtual processor executing code that executes smart contracts. For Ethereum this would be Ethereum Virtual Machine(EVM) executing compiled solidity code. For bitcoin blockchain this would be Virtual Processor executing script code. Layer 3: Application Programming Interface(API) this performs multiple functions such as: • Converting smart contract code to bytecode • Wallet requests for transaction processing • Exposing blockchain explorer capability Layer4: This is where outside world interacts with Layers 3, 2, and 1. Weakest Link The weakest link is Layer 4. This is where all the problems start. First, the wallets, if the owner does not protect the private key and passphrase or they are exposed, all the crypto held in that wallet can be lost. Second, the smart contracts, if the smart contract code is not written properly then the inherent compiled byte code that lives on the blockchain will have vulnerabilities. If some one is able to exploit this particular vulnerability the impacts can be very damaging. Just like the DAO hack which lead to over $60m getting stolen. Some solutions Since smart contract is just code, it has to follow secure coding practices. Although there are a lot of secure coding methodologies, and tools available for conventional programming languages such as C, C++, C#, Java, JavaScript, etc., there was nothing available for newly created smart contract languages such as solidity and script. With the lack of secure coding practices & tools, coupled with inexperienced programmers in these new languages, it was a disaster waiting to happen. Tools Various organizations are now bringing out blockchain security tools to address this void. Here is the list: • A platform should support conventional programming languages to ensure existing secure coding practices can be leveraged. • OpenZeppelin has created an open framework of reusable and secure smart contracts in the Solidity language. • Trailofbits has created following tools: ○ A repository that contains examples of common Ethereum smart contract vulnerabilities, including real code. ○ "Slither combines a set of proprietary static analyses on Solidity that detect common mistakes such as bugs in reentrancy, constructors, method access, and more. Run Slither as you develop, on every new checkin of code." ○ "Echidna applies next-generation smart fuzzing to EVM bytecode. Write Echidna tests for your code after you complete new features. It provides simple, high coverage unit tests that discover security bugs. Until your app has 80+% coverage with Echidna, don’t consider it complete". ○ "Manticore uses symbolic execution to simulate complex multi-contract and multi-transaction attacks against EVM bytecode. Once your app is functional, write Manticore tests to discover hidden, unexpected, or dangerous states that it can enter. Manticore enumerates the execution states of your contract and verifies critical functionality". ○ They have also created some reversing tools just like Porosity below which converts bytecode to solidity code. • NCC Group had compiled a DASP (Decentralized Application Security Project) Top10 list • Porosity, a decompiler and smart contract auditing tool for Ethereum smart-contracts.

Making Blockchain Real with Hyperledger Fabric v1 by Eric Cattoir
Blockchain, a completely new architecture for business. Its shared ledger technology establishes trust and transparency, whenever valuable assets are transferred from one party to another. You know for certain that a record — anything from a proof of identity or ownership, to the terms of a business agreement — is unique and unchangeable by any party without the agreement of all parties. With Hyperledger Fabric v1 the promise and potential of Blockchain is becoming more and more reality. In this session, we explore the capabilities of Hyperledger Fabric and we’ll discuss how applications can be built. # Eric Cattoir During a 20 year career at IBM Eric was involved with many customer projects of various sizes. He has a long experience in all kind of development related technologies, ranging from Mainframe environments till mobile and internet of things. He has been involved in aspects of modernizing existing environments as well as in implementing new technologies. He has experience both with deep down development, but also with methodology, architecture and change consultancy. Currently he is a consultant within the IBM Rational practice, consulting with customers around many application lifecycle management topics (agile, mobile development, devops, implementing cloud platforms, requirements, testing,...) Eric also enjoys coaching at Coderdojo.
