Blockchain vs Traditional Databases. Is Blockchain the Future? (the Investigation)
 
10:54
The Investigation Into Blockchain and Traditional Databases - is Blockchain the Future? What is a database? Database is a collection of information that is organized so that it can be easily accessed, managed and updated. Data gets updated, expanded and deleted as new information is added. The applications are using databases to get information. There are several different types of databases but the main ones are: a) Relational databases are made up of a set of tables with data that fits into a predefined category. Each table has at least one data category in a column, and each row has a certain data entry. b) A cloud database is a database that has been optimized or built for a virtualized environment, either in a hybrid cloud, public cloud or private cloud. c) A distributed database is a database in which portions of the database are stored in multiple physical locations, and in which processing is dispersed or replicated among different points in a network. d) There are also other less known types available. What is blockchain? It's a shared ledger for recording the history of transactions - that cannot be altered. While complex in nature the actual idea behind blockchain is quite simple: a) As each transaction occurs it's put into a block b) Each block is connected to the one before and after it c) Transactions are blocked together. d) Each block is added to the next in an irreversible chain. Blockchains are commonly operated through thousands of global computers in an open peer-to-peer network meaning the data isn't stored in a single location or across a single server They can be public or private depending on the use-cases Distributed database? Blockchain has some similarities to distributed database since the data is kept on several machines. There are also differences though. In a databse users trust all the machines (since they are all in admin control) so the machines are not expected to compromise the integrity of data. On the blockchain, users don't trust any of the machines but expect that over 51% of the computers connected to the network are honest Blockchains in general can also be considered more limited than distributed databases but they also have advantages so it's basically a case of seleting the better tool. Advantages and disadvantages 2 main advantages Robustness: blockchains are usually tamper-proof. Once recorded the transactions cannot be altered. Decentralisation: Require no central administrator since blockchain transactions contain their own proof of validity and their own proof of authorization 2 main disadvantages Confidentiality: every node in a blockchain independently verifies and processes every transaction, there are some solutions to change it like advanced cryptographic techniques but those are exceptions and not a rule Blockchains will always be slower than centralized databases simply due to how they work. Blockchain Usage Bitcoin is the original and the most popular use case for blockchain - it is esentailly used to record transactions on the blockchain. Basically Internet money. Introduction of smart contracts changed blockchain use cases. Smart contract is a computer program that directly controls the transfer of digital currencies or assets between parties under certain conditions. This means that wile Bitcoin is a simple transfer of value with contracts you can do that transfer only if certain conditions are filled. Ethereum made smart contracts popular and opened a whole new different world for blockchain. Currently they are mostly used for crowdfunding but in the future there should be several great use cases that could revolutionise we use computers and electronic devices.

Trent McConaghy  - BigchainDB : a Scalable Blockchain Database, in Python
 
43:20
PyData Berlin 2016 This talk describes BigchainDB. BigchainDB fills a gap in the decentralization ecosystem: a decentralized database, at scale. It has big-data performance levels, a querying system, and a permissioning system that supports public and private versions. It's complementary to decentralized processing platforms like Ethereum, and decentralized file systems like IPFS. BigchainDB is written in Python. This talk describes BigchainDB. BigchainDB fills a gap in the decentralization ecosystem: a decentralized database, at scale. It points to performance of 1 million writes per second throughput, storing petabytes of data, and sub-second latency. The BigchainDB design starts with a distributed database (DB), and through a set of innovations adds blockchain characteristics: decentralized control, immutability, and creation & movement of digital assets. BigchainDB inherits characteristics of modern distributed databases: linear scaling in throughput and capacity with the number of nodes, a full-featured NoSQL query language, efficient querying, and permissioning. Being built on an existing distributed DB, it also inherits enterprise-hardened code for most of its codebase. Scalable capacity means that legally binding con- tracts and certificates may be stored directly on the blockchain database. The permissioning system enables configurations ranging from private enterprise blockchain databases to open, public blockchain databases. BigchainDB is complementary to decentralized processing platforms like Ethereum, and decentralized file systems like InterPlanetary File System (IPFS). This talk describes technology perspectives that led to the BigchainDB design: traditional blockchains, distributed databases, and a case study of the domain name system (DNS). We introduce a concept called blockchain pipelining, which is key to scalability when adding blockchainlike characteristics to the distributed DB. We present a thorough description of BigchainDB, a detailed analysis of latency, and experimental results. The talk concludes with a description of use cases.

IoT Blockchain Convergence
 
05:33
Short video slide about the convergence of The Internet of Things(IoT) and the blockchain. Produced by: http://complexitylabs.io Twitter: https://goo.gl/ZXCzK7 Facebook: https://goo.gl/P7EadV LinkedIn: https://goo.gl/3v1vwF Transcription: The internet is evolving into a new technology paradigm based around smart systems, the blockchain, platforms, and IoT in the coming years, these technologies will interact and converge in new and unpredictable ways The convergence of IoT and blockchain will be a major part of this evolution, enabling new automated service systems and business models... but many unresolved issues remain IOT Internet of Things is the merging of our engineered physical environment with information systems to create smart adaptive objects and environments... it is a fast-growing, increasingly complex network of connected physical systems that are able to process information and communicate peer to peer in order to enable common services. These devices are becoming increasingly ubiquitous ranging from autonomous vehicles to sensors monitoring industrial processes, to smart homes and smart cities. IoT is growing rapidly, according to Gartner the global IoT network will connect 26 billion devices by 2020. The development of an IOT infrastructure to our economies will probably be the greatest engineering challenge of our time... dealing with the sheer amount of data due to come on-stream and security are primary concerns... before mainstream Internet-of-Things adoption can really take hold in a safe and sustainable fashion, these, among other issues, will need to be resolved. Blockchain The blockchain is a secure distributed database for recording transactions... millions of computers networked to create a distributed database for recording and authenticating exchanges of value. With the blockchain, value of any kind can be exchanged directly peer to peer without a centralized authority to record and validate the transaction. The blockchain can provide an automated and secure transaction infrastructure for next generation IoT systems... in its capacity to track billions of connected devices and enable the frictionless processing of transactions and coordination between devices. This decentralized approach would eliminate single points of failure, bottlenecks and potentially make data and transactions more secure.... creating a more resilient ecosystem for devices to run on. Likewise, it would automate transactions, enabling fully autonomous service systems; reduce cost and reduce settlement time from days to seconds One example of an IoT Blockchain system is Slock, a door lock that is connected to a smart contract on the blockchain that controls when and who can open the lock. “The owner of a Slock can set a deposit amount and a price for renting his property, and the user will pay that deposit through a transaction to the Ethereum blockchain, thereby getting permission to open and close that smart lock through their smart phone.” - Christoph Jentzsch Such technology bridges the blockchain and the physical world by making automated smart contracts, thus enabling the frictionless and automated temporary exchange of assets such as bikes, parking lots or rooms. "Smart contracts, a feature of “Bitcoin 2.0” technologies such as Ethereum, could soon operate on the Internet of Things (IoT), control objects in the physical world, and power a new decentralized version of the sharing economy, for example sharing services similar to Uber and Airbnb that operate in pure P2P mode without centralized management." - Bitcoin Magazine Leveraging blockchain for IoT offers new ways to automate business processes and build distributed autonomous service systems... "The true value of the underlying technology -- the blockchain -- has only just begun to be explored, and potential applications to the Internet of Things and Smart Systems are vast."

Permissioned Blockchains and Databases
 
01:14:56
Speaker: Dr. C. Mohan IBM Fellow and Former IBM India Chief Scientist IBM Almaden Research Center Abstract: Blockchain (distributed ledger), the underlying technology of Bitcoin, has become very popular for use in commercial or permissioned environments. Computer companies like IBM and Microsoft, and many key players in different vertical industry segments have recognized the applicability of blockchains in environments other than cryptocurrencies. IBM did some pioneering work by architecting and implementing Fabric, and then open sourcing it. Now Fabric is being enhanced via the Hyperledger Consortium as part of the Linux Foundation. While there is no standard in the blockchain space currently, all the ongoing efforts involve some combination of database, transaction, encryption, consensus and other distributed systems technologies. Dr. Mohan will focus on how the functionality of traditional and modern data stores are being utilized or not utilized in the different blockchain projects. Since most of the blockchain efforts are still in a nascent state, he believes the time is right for database researchers and practitioners to get more deeply involved.

Blockchain Technology Explained: What is a Blockchain?
 
04:01
This video https://youtu.be/eXJHPDs4M3Y provides an easy to understand introduction to Blockchain Technology. Please leave comments and questions below the video. Here is the full transcript for your convenience: What is a Blockchain? A Blockchain is a distributed database that multiple parties share and everyone can trust. A Blockchain network provides a mutually trusted, transparent way of sharing and transacting. Each party participating in a Blockchain network maintains their own copy of the database. What makes Blockchain secure? Transactions on the database are atomic (this means that they're processed one at a time). The next transaction will be a different write or a read, but only after the preceding transaction has completed (or failed). Each write to the database is considered a ‘block’. Each new block contains a cryptographic hash (a unique fingerprint) of the previous block, creating a chain that can always be validated by checking the hashes back to the original root block. Before a block can be committed, all participants are required to validate the transaction and provide consensus that the block can be added to the chain. This effectively makes it impossible to add a record unless all parties participating in the blockchain agree the record is valid. Because all records are chained together by their hash value, once committed to the chain, all records are immutable (they cannot be changed). It is impossible to alter a previous record without altering every party’s copy of the chain. If one node is compromised, then it can no longer participate in the chain until it regenerates the true chain from the other participants. How does Blockchain prevent double spending? A major challenge of digitising assets is the potential to spend/redeem/use an asset multiple times. Because digital assets are much easier to forge than many traditional assets (such as currency, tickets, physical coupons, etc.), a secure system is required to ensure that an asset is only used once. With Blockchain, every time an asset is used or consumed, the owner of the asset signs the transfer with a private cryptographic key. This key is unique to the owner and is extremely difficult to forge. In order to initiate the transaction, the transferrer requires both the asset and their private key. The Blockchain will check both the validity of the key, and ownership of the asset. Therefore, even if the asset is cloned, it cannot be used without the private key. Once the transaction has been committed to the chain, the owner of the asset will have changed. This means, each node that receives a second transaction requesting transfer of ownership (or redemption, etc.) will see that there was a previous transaction that already transferred the asset and will reject that transaction. This prevents a second transfer block from being added to the chain. How does Blockchain ensure privacy? Personal data and identifiers are not required to be stored in the chain. Such data is stored as a hash value which provides both anonymity and security. The user may provide data such as their name, telephone number, email address, Facebook account id, unique user name, password etc. (in reality a combination of these values is used) to determine their identity. This data is hashed to provide a unique token that can only be recreated by providing the original values, and only this hash is stored to identify the party in the chain. Since it is impossible to obtain the input values by reverse engineering a hash value, the user is practically anonymous to all parties within the chain. But, they can be validated whenever required by providing the original values used to create the hash. How is PassKit utilising Blockchain? PassKit provides a private blockchain service to parties that wish to issue, record or redeem anything of value. This can be anything from loyalty points, punch card programmes, event tickets, boarding passes, to government identification, insurance policies or claim histories, tax records and educational transcripts. We utilise existing mobile wallet technology as a gateway for transacting, validating or querying our secure, private Blockchain networks. We ensure that mobile wallet content can be validated and trusted in a frictionless, realtime manner, by both consumers and by the businesses and institutions with whom they transact.

Blockchain tutorial 6: Digital signature
 
04:48
This is part 6 of the Blockchain tutorial explaining what a digital signature is. 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.

New Era in Distributed Computing with Blockchains and Databases
 
01:15:46
A new era is emerging in the world of distributed computing with the growing popularity of blockchains (shared, replicated and distributed ledgers) and the associated databases as a way of integrating inter-organizational work. Originally, the concept of a distributed ledger was invented as the underlying technology of the cryptocurrency Bitcoin. But the adoption and further adaptation of it for use in the commercial or permissioned environments is what is of utmost interest to me and hence will be the focus of this keynote. Computer companies like IBM and Microsoft, and many key players in different vertical industry segments have recognized the applicability of blockchains in environments other than cryptocurrencies. IBM did some pioneering work by architecting and implementing Fabric, and then open sourcing it. Now Fabric is being enhanced via the Hyperledger Consortium as part of The Linux Foundation. A few of the other efforts include Enterprise Ethereum, R3 Corda and BigchainDB. While there is no standard in the blockchain space currently, all the ongoing efforts involve some combination of database, transaction, encryption, consensus and other distributed systems technologies. Some of the application areas in which blockchain pilots are being carried out are: smart contracts, supply chain management, know your customer, derivatives processing and provenance management. In this talk, I will survey some of the ongoing blockchain projects with respect to their architectures in general and their approaches to some specific technical areas. I will focus on how the functionality of traditional and modern data stores are being utilized or not utilized in the different blockchain projects. I will also distinguish how traditional distributed database management systems have handled replication and how blockchain systems do it. Since most of the blockchain efforts are still in a nascent state, the time is right for database and other distributed systems researchers and practitioners to get more deeply involved to focus on the numerous open problems. Speaker Bio Dr. C. Mohan has been an IBM researcher for 35 years in the database area, impacting numerous IBM and non-IBM products, the research and academic communities, and standards, especially with his invention of the ARIES family of database locking and recovery algorithms, and the Presumed Abort commit protocol.

Bitcoin Q&A: What should not go on a blockchain?
 
05:26
Keywords/phrases: What should NOT go on a blockchain? 80% of what people are saying should be implemented on "blockchain." Right now, "blockchain" is a hammer and everything that looks like a nail is getting hit, which is mostly breaking things and not producing anything useful. Nobody really knows what a blockchain is, and it's being defined in such a ridiculously broad way. "Blockchain" is ultimately a meaningless word. Trust, transparency, and immutability are not properties of the blockchain; they are properties of a system that combines a blockchain, an open consensus mechanism with a proof-of-work investment in extrinsic energy, and a native asset that creates a game-theoretical reward system. They all work in conjunction to massively increase the decentralisation of the system until its decentralisation range is so high that immutability, security, transparency, and openness emerge as characteristics. You can't just say "let's do all of that without the decentralisation." If you are currently involved in a large proof-of-concept project where some consultant is selling you the abstract noun "blockchain," and they're telling you that the system you have now can be replaced with all these magical characteristics, take the word "blockchain" from the proposal and replace it with "Microsoft Sequel Server, Data Center Edition." If the proposal still works from an IT perspective, buy that instead. If you're using "blockchain" to mean "database," plus some hashes and signatures, you are missing the point. The magic of this technology is the decentralisation, and to remove that is to remove the magic; that is the measure for success from which all the interesting characteristics emerge from.

The Bitcoin and Blockchain Technology Explained
 
06:16
A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history. ------------------------------------------------------------------- BUY BITCOIN SAFELY HERE: http://bit.ly/BuyBitcoinNow ------------------------------------------------------------------- REGISTER FOR A COINBASE ACCOUNT: http://bit.ly/CoinbaseBitcoinSignup ------------------------------------------------------------------- Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin. Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block. For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes. Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists. These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children. Because a block can only reference one previous block, it is impossible for two forked chains to merge. • How do Bitcoin Transactions Work? http://www.coindesk.com/information/how-do-bitcoin-transactions-work/ ------------------------------------------------------------------- DID YOU LIKE THIS VIDEO? ------------------------------------------------------------------- Enjoy this video?

Blockchain tutorial 23: Ledger
 
02:35
This is part 23 of the Blockchain tutorial explaining what a ledger is. This tutorial explains the differences between: - a centralised and a distributed ledger - a public ledger (permissionless ledger) and a private ledger (permissioned ledger) 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.

The blockchain is a distributed ledger technology that underlies cryptocurrencies like Bitcoin and platforms like Ethereum. It provides a way to record and transfer data that is transparent, safe, auditable, and resistant to outages. The blockchain has the ability to make the organizations that use it transparent, democratic, decentralized, efficient, and secure. It's a technology that holds a lot of promise for the future, and it is already disrupting many industries.

BigchainDB Version 1.0 Released - Live Coding Demo
 
38:20
In talks with of our customers throughout the past year, it became clear that for them to build and ship production software, BigchainDB’s main API gateways and data models will have to mature and stabilize. Late 2016, this lead us to schedule BigchainDB version 1.0 for summer 2017. We themed it around “My data is safe” and backwards-compatibility. Since then we’ve deployed BigchainDB for the IPDB test and production net, cleaned up and improved our HTTP and WebSocket APIs, added support for an additional database back end (MongoDB) and completed major efforts to ensure the system’s security and correctness. All the more, we’re proud to announce a major development milestone for BigchainDB today with the release of version 1.0. It comes packed with new features, improvements, fixes and backwards-compatibility. Among other things, its new functionality includes asset querying and a JavaScript driver.

But while most people have heard of Bitcoin and blockchain, few fully grasp the technology behind it. Spoiler: blockchain is NOT a magical database in the cloud, but can perhaps be considered one of the slowest distributed databases known to man. But if blockchain is the slowest distributed database known to man, why are people using it? This talk will explore the benefits and true costs of blockchain technology. You will learn why blockchain is not as flawless as we've been led to believe, but how the transparency that comes with it has unlocked a whole new set of possibilities.

Analyzing Blockchain and Bitcoin Transaction Data as Graph
 
51:44
Blockchain technology and Bitcoin will potentially revolutionize business transactions. Blockchain offers a robust, decentralized platform for privacy and trust. It underlies the digital crypto-currency Bitcoin, which can be exchanged freely and anonymously, without a central authority. Bitcoin transactions - recorded publicly, provide an invaluable dataset to gain insight into the behavior of digital currency and the underlying Blockchain technology. Blocks, transactions with potential multiple inputs and outputs, and flow of bitcoins between addresses, form a sophisticated real-time graph. This talk details a pipeline used to gather bitcoin transaction data and analyze it with powerful graph cloud database technologies. Zhe Wu is an architect working on semantic and graph technologies in Oracle USA. He leads the design, architecture, and development of the inference engine for W3C RDFS/SKOS/OWL in the database, Java APIs for RDF Semantic Graph, RDF triple-level security, SQL-based graph analytics, Property Graph for RDBMS and Hadoop, and more.
