Bitcoin Q&A: Scaling is a moving target
 
06:57
Scaling solutions, advantages and disadvantages. I won't take a position on scaling options for a simple reason: I think we will do all of them. SegWit, second layer implements like Lightning Network, increasing the base block size with 4-8 Mb of capacity, Schnorr signatures, Spoonnet. Scaling is not something that is solved once; scaling is a moving target, an aspiration. As you achieve each level of scale, that opens the door for new applications; solving current problems creates the opportunity for new problems. The internet has been failing to scale for 25 years. Email, image attachments, audio, video, high-definition video, livestreaming, holographic virtual reality, etc. We have a system that allows for global transactions, without borders, a level of planetary scale immutability. As soon as we make it faster and cheaper, people will want to put _more_ data on the blockchain. We will reach Visa scale and then surpass Visa scale on an exponential curve. We can never "fix" scaling. All we can do is hope to continue to fail to scale gracefully. Solutions that are technically sensible, maintainable, and don't violate the core principles of decentralisation. We can change the rules as often as we like, but we should not appoint rulers.

Blockchain 101 Ep 59 - What is Hash Algorithm?
 
01:16
Hash Algorithm is a cryptographic algorithm that deals with encryption but not decryption. It is able to map data of arbitrary size to a bit string of a fixed size. The string has two unique characteristics : Firstly, a small change to the input would change the hash value entirely. Secondly, only an exact input would result in the same output. There is no pattern between the generated input and the output values, hence it is impossible to reverse engineer the input value based on the output value. The hash value can only be determined through trial-and-error. Trying all possible input values to determine the hash value that fulfils all prerequisites. Hash Algorithm ensures that it is not possible to derive the solution by working backwards in Bitcoin mining. As such, miners work continuously to compute the hash value, which is basically a brute-force attack to guess the correct value. The first miner to find it will receive Bitcoin rewards.

Bitcoin Cash new cryptocurrency explained! Bitcoin August Fork Split
 
07:41
Please watch: "How Facebook targeted advertisements track you online, offline and where they sell your private data" https://www.youtube.com/watch?v=9sFl2qGedFQ -~-~~-~~~-~~-~- Hi, this is Bitcoin Cash explained video. What is Bitcoin Cash? A new cryptocurrency was created as fork of original Bitcoin. Explaining Bitcoin Cash is like trying to shoot a moving target - there is lot going on in with the new blockchain. At some point, it looked like Bitcoin Cash will crash, but right now it does receive more support from mining pools. After all, everybody who owned bitcoins on August 1st would be rewarded equal amount Bitcoin Cash. That's some extra money for free, right? This video is about Bitcoin Cash explained! Enjoy my bitcoin cash video explanation! Well not so many people were to eager to deal with Bitcoin Cash, which resulted in a state where it was impossible to move it, sell it, or cash for fiat money (e.g. dollars). So what is Bitcoin Cash exactly? What is bitcoin cash? Bitcoin Cash is a fork of Bitcoin. Bitcoin is an open source cryptocurrency that relies on pure mathematics and economics to determine its value. Since the software of Bitcoin is open source, anybody can take it and create their own currency. The real catch here is that it needs to be supported, if you want it to have any value. Bitcoin cash fork a new cryptocurrency Bitcoin Cash was created because some developers and few big mining pools wanted to increase size of Bitcoin blocks from 1 MB to 8 MB. Each block holds a number of transaction, which take up some space of bytes. These are blocks are validated by solving difficult puzzles, for which miners receive rewards (Bitcoins). Bitcoin blocksize limit debate However, the bitcoin's block size limit allowed maximum of 7 transactions a minute. And as Bitcoin grows in number of users, this cap was soon to be hit, which resulted in slow down of confirmations of transactions. Bitcoin growth The limit is made to secure the network and ensure its decentralized nature that prevents big players from gaining control. That wasn't appealing to some people who view Bitcoin's growth as more important than decantralization and security. This dispute over Bitcoin's block size limit was going on for over 2 years and escalated into now forking Bitcoin Cash as a separate cryptocurrency independent from Bitcoin. Both Bitcoin and Bitcoin Cash exist and trade simultaneously, and they have no direct effects on another. Difference between Bitcoin and Bitcoin Cash is now like between Bitcoin and Ethereum, or any other cryptocurrency in the world. What does Bitcoin split to Bitcoin Cash mean in the long run? That's really hard to tell. Bitcoin Cash was made to surpass or even replace original bitcoin, but bitcoin is now growing value, surpassing $3,000 dollar milestone just after the fork of Bitcoin Cash. Bitcoin will implement SegWit, Segregated Witness, to deal with the pressure of its own growth. You'll learn what is segwit in this video. Nevertheless, it's going to be extremely interesting and worthwhile studying cryptocurrency as they keep growing on value, influence, and bitcoin is now even entering mainstream.

SDS|2016: Paulina Figol on What does blockchain mean for Data Science?
 
24:03
Abstract. The presentation entails the implications of using blockchain in data science. This technology is a distributed database and is fundamentally a new paradigm for organizing any kind of transactional activity - cheaper, with more efficiency and at much greater scale. The 2015 World Economic Forum underlined the concept as one of the six future megatrends for the next decade. The technology’s intelligence layer, initially designed for Bitcoin transactions, applies advanced machine learning and distributed systems to cryptographic platforms. This facilitates various types of transactions within enterprises, such as financial services or banks, to make smart and quick real time decisions, while maintaining data privacy and trust. A case study of a commercial blockchain version of Uber application will be presented to visualize the concept and to provide analytical insight. The main implication for data science is Big Data predictive task automation that allows tracking and automated administration of all classes of transactions. Also, emergence of consensus data – data with confirmed quality, accuracy and trust value – will allow time reduction for data profiling activity. These will not become reality unless governments and businesses adapt quickly to new tools and platforms, such as adopting the blockchain to create new taxation mechanisms or overcoming technical challenges. The most relevant in terms of data science will be: a limitation of 7 transactions per second, block size and countering vulnerability to 51 percent mining attacks. In summary, the presentation will underline blockchain’s importance in data science along with its potential strengths and adoption challenges. It will provide an analytical insight of the technology, considered as a future IT infrastructural element for both businesses and governments.

#248 Uri Klarman: bloXroute – Layer-0 Scaling with the Blockchain Distribution Network
 
01:20:23
Support the show, consider donating: BTC: 1CD83r9EzFinDNWwmRW4ssgCbhsM5bxXwg (https://epicenter.tv/tipbtc) BCC: 1M4dvWxjL5N9WniNtatKtxW7RcGV73TQTd (http://epicenter.tv/tipbch) ETH: 0x8cdb49ca5103Ce06717C4daBBFD4857183f50935 (https://epicenter.tv/tipeth) Until now, proposals to improve blockchain scalability have addressed the problem in one of two ways. One seeks to increase efficiency by optimizing the blockchain or improving the consensus algorithm. The other comes in the forms of layer-2 solutions such as payment channels or side chains. However, none have addressed the core bottleneck to scalability: TCP/IP network limitations. Improving the speed at which blocks propagate through the network is the layer-0 problem few people consider when thinking about scaling. Fundamentally, network bottlenecks are what prevent blockchains from increasing their transaction throughput. Raising the block size or reducing the time between blocks has devastating effects on usability as the probability of a fork increases. At a certain point, the blockchain simply breaks as forks occur faster than blocks can propagate to all validators. Remarkably, the web figured out how to scale decades ago with the invention of Content Distributions Networks, or CDN. This is what enables platforms like YouTube to steam thousands of hours of video to hundreds of thousands of people every second. However, traditional centralized scaling solutions lack the privacy and censorship resistance necessary to serve the decentralized web. We're joined by Uri Klarman, CEO of bloXroute. Founded by a team of researchers and systems designers from Northwestern and Cornel University, including Emin Gün Sirer, bloXroute allows practically every blockchain network to “scale today.” As a scalability infrastructure service, their Blockchain Distribution Network, or BDN, sits underneath blockchain networks. Anyone operating a miner can use the BDN without any changes to their consensus algorithm or protocol. By simply pointing their software to a bloXroute node, miners immediately benefit from propagation speeds orders of magnitude higher than the time which is currently required for blocks to be seen by all validators. This global network of servers is optimized to receive and stream massive amounts of transaction data to vast networks of nodes and miners. While bloXroute relies on some level of centralization, it is provably neutral and cannot discriminate based on the contents, provenance or destination of a block. It also includes clever redundancy mechanisms which ensure availability in the event of an attack on the network. Topics discussed in this episode: - Uri's journey as an academic working in the field of networking - Defining the blockchain scalability problem as a networking problem - Past work and attempts to scale blockchains - The vision behind bloXroute and the problem it aims to solve - The Blockchain Distribution Network (BDN) and its technical architecture - How the BDN optimizes blocks and achieves 1,000x faster propagation times - How bloXroute archives provable neutrality and ensures network resiliency - The BLXR token and incentive mechanisms - The project's goals, milestones, and product roadmap Links mentioned in this episode: - bloXroute Website: https://bloxroute.com/ - bloXroute White Paper: https://bloxroute.com//wp-content/uploads/2018/03/bloXroute-whitepaper.pdf Sponsors: - Shapeshift: Buy and sell alt coins instantly and securely without a centralized exchange - http://epicenter.tv/shapeshift This episode is also available on : - Epicenter.tv: https://epicenter.tv/248 - YouTube: http://youtu.be/WmzH8Lz7L1U - Souncloud: http://soundcloud.com/epicenterbitcoin/eb-248 Watch or listen, Epicenter is available wherever you get your podcasts.

IOHK | Symphony of Blockchains Meetup in London
 
01:28:39
The Symphony of Blockchains is an interactive, visual and auditory exploration of Bitcoin, cryptocurrency and the blockchain. It is an ongoing research initiative with a singular aim: to help bring about greater understanding of both blockchain technology and the ever expanding (and contracting) cryptocurrency marketplace. This video was recorded on location from the latest Symphony of Blockchains Meetup in London with designers from both IOHK and the founder of Kuva. We also hear from the CEO of IOHK on the importance of design and experiences in the blockchain space. In this project, we explore the blockchain of Bitcoin as a physical structure. We examine its inherent underlying qualities by encapsulating data as crystalline forms connected in space, that are immutable and persistent. Using this as a metaphor provides a means to understand the Bitcoin blockchain. Blocks take on the properties of the data, their size, colour and orientation represent various qualities. Blocks are orientated in a spiral tracing back through time, each periodic rotation representing a day in the life of the blockchain. Their size and colour represent the total value of transactions made. Once the blockchain is loaded users simply scroll up or down to move forward or back in time through the blockchain. Using their pointer (or finger on mobile devices) they can easily select an individual node or block in the chain to investigate it further. Once accessed, the user is presented with a view of the unique Merkle tree that identifies that specific block. In addition to the Merkle tree view, the user is presented with a plethora of information giving detail about the transaction the selected block represents. To exit the block view the user simply clicks away.

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.

What is Hashing & Digital Signature in The Blockchain?
 
06:19
What is Hashing & Digital Signature in The Blockchain? https://blockgeeks.com/ Today, we're going to be talking about the word blockchain and breaking it down to understand what does it mean when someone says, "Blockchain." What is hashing? Hashing refers to the concept of taking an arbitrary amount of input data, applying some algorithm to it, and generating a fixed-size output data called the hash. The input can be any number of bits that could represent a single character, an MP3 file, an entire novel, a spreadsheet of your banking history, or even the entire Internet. The point is that the input can be infinitely big. The hashing algorithm [00:01:00] can be chosen depending on your needs and there are many publicly available hashing algorithms. The point is that the algorithm takes the infinite input of bits, applies some calculations to them, and outputs a finite number of bits. For example, 256 bits. What can this hash be used for? A common usage for hashes today is to fingerprint files, also known as check zones. This means that a hash is used to verify that a file has not been [00:01:30] tampered with or modified in any way not intended by the author. If WikiLeaks, for example, publishes a set of files along with their MD5 hashes, whoever downloads those files can verify that they are actually from WikiLeaks by calculating the MD5 hash of the downloaded files, and if the hash doesn't match what was published by WikiLeaks, then you know that the file has been modified in some way. How does the blockchain make use of hashes? [00:02:00] Hashes are used in blockchains to represent the current state of the world. The input is the entire state of the blockchain, meaning all the transactions that have taken place so far and the resulting output hash represents the current state of the blockchain. The hash is used to agree between all parties that the world state is one in the same, but how are these hashes actually calculated? The first hash is calculated for the first block [00:02:30] or the Genesis block using the transactions inside that block. The sequence of initial transactions is used to calculate a block hash for the Genesis block. For every new block that is generated afterwords, the previous block's hash is also used, as well as its own transactions, as input to determine its block hash. This is how a chain of blocks is formed, each new block hash pointing to the block hash that came before it. This system of hashing guarantees that no transaction in the history can be tampered with because if any single part of the transaction changes, so does the hash of the block to which it belongs, and any following blocks' hashes as a result. It would be fairly easy to catch any tampering as a result because you can just compare the hashes. This is cool because everyone on the blockchain only needs to agree on 256 bits to represent the potentially infinite state of the blockchain. The Ethereum blockchain is currently tens of gigabytes, but the current state of the blockchain, as of this recording, is this hexadecimal hash representing 256 bits. What about digital signatures? Digital signatures, like real signatures, are a way to prove that somebody is who they say they are, except that we use cryptography or math, which is more secure than handwritten signatures that can be [00:04:00] easily forged. A digital signature is a way to prove that a message originates from a specific person and no one else, like a hacker. Digital signatures are used today all over the Internet. Whenever you visit a website over ACTPS, you are using SSL, which uses digital signatures to establish trust between you and the server. This means that when you visit Facebook.com, your browser can check the digital signature that came with the web page to verify that it indeed originated from Facebook and not some hacker. In asymmetric encryption systems, users generate something called a key pair, which is a public key and a private key using some known algorithm. The public key and private key are associated with each other through some mathematical relationship. The public key is meant to be distributed publicly to serve as an address to receive messages from other users, like an IP address or home address. The private key is meant to be kept secret and is used to digitally sign messages sent to other users. The signature is included with the message so that the recipient can verify using the sender's public key. This way, the recipient can be sure that only the sender could have sent this message. Generating a key pair is analogous to creating an account on the blockchain, but without having to actually register anywhere. Pretty cool. Also, every transaction that is executed on the blockchain is digitally signed by the sender using their private key. This signature ensures that only the owner of the account can move money out of the account.

IOHK | Symphony of Blockchains
 
25:14
The Symphony of Blockchain is an interactive, visual and auditory exploration of Bitcoin, cryptocurrency and the blockchain. It is an ongoing research initiative with a singular aim: to help bring about greater understanding of both blockchain technology and the ever expanding (and contracting) cryptocurrency marketplace. The term ‘Blockchain’ is being increasingly found in everyday language, with little explanation or understanding the technology and its implication for the future. This work aims to explain both Blockchain technology and it’s most visible application — cryptocurrencies. Through this visualisation we explain the concept underpinning Blockchain as well as the individual transactional detail and ultimately the health within any cryptocurrency. As the technology becomes more pervasive and it impacts on everyday life more, it’s important that we attempt to explain it in a meaningful way. Cryptocurrencies are built upon a technology known as blockchain; a decentralized and distributed system that encodes its own existence as a recorded history through time. In Symphony we explore the blockchain of Bitcoin as a physical structure. We examine it’s inherent underlying qualities by encapsulating data as crystalline forms connected in space, immutable and persistent. Using this as a metaphor provides a means to understand it. Blocks take on the properties of the data, their size, color and orientation represent various qualities. Blocks are orientated in a spiral tracing back through time, each periodic rotation representing a day in the life of the blockchain. Their size and color representing the total value of transactions made. Symphony also explores the blockchain as an auditory experience. We ask a simple question; ‘What does the blockchain sound like?’ Using the frequency and timing of bitcoin transactions as a foundation, the audio extends the crystalling structures by encoding as an sound based entity The background sound is an ambient soundscape created from real recordings of computer power supplies and fans to emulate the sound of bitcoin mining.The intensity of the sound varies with the hashrate of the network. The audio of the Merkle tree is based on the transactions of the block. A repeating loop is set to run every musical measure (a segment of time corresponding to a specific number of beats in which each beat is represented by a particular note value) Transactions are arranged in ascending order based on the time they were made. The timescale of a block from the earliest to the latest mined, is mapped from 0 to 30 seconds. Each transaction sound is triggered and set to loop based on the mapped time value (quantized to the nearest 32nd note). As the master loop repeats, notes accumulate and build up a pattern. The note of each transaction sound is based on the position on the y-axis, to the nearest note in the Aeolian mode. When it came to the user experience we wanted to ensure it was effortless to explore. The concepts and technologies we’re attempting to explain are complex enough. We didn’t want users having to fathom out a complex navigation system on top of it all. Once the Blockchain is loaded users simple scroll up or down to move forward or back in time through the blockchain. Using their pointer (or finger on mobile) they can simply select an individual node or block in the chain to investigate it further. Once accessed the user is presented with a view of the unique Merkle tree that identifies that specific block. In addition to the Markle tree view the user is presented with a plethora of information regarding the detail around the transaction the selected block represents. To exit the block view the user simply clicks away. IOHK CEO Charles Hoskinson: "IOHK has a commitment to both education and design and this captivating and complex data visualization is the perfect combination of both. It’s beautiful as much as it is functional and our hope is that it will help make blockchain truly understandable for a whole new audience."

Bitcoins Schnorr Coming, and what it means for the blockchain
 
05:53
Schnorr - increases transaction speed, privacy, and the scalability of the blockchain Schnorr enhances Bitcoin’s current key generation system, the Elliptical Curve Digital Signature Algorithm. Once implemented it would provide mathematical proof that the algorithms are safe unlike ECDSA which currently does not. Also, it will allow the use of less bandwidth in transactions, increasing efficiency and scalability. Transaction Speed- Only Slightly faster, A 50-of-50 transaction is effectively the same size as one that uses a single public key and signature. For this reason, the performance of such schemes is significantly improved by removing the original requirement of validating every signature individually Privacy- Schnorr allows the entire policy of the multisig to be obscured and indistinguishable from a conventional single pubkey. In a threshold setup, it also becomes impossible for participants to reveal which of them authorized, or not, a transaction. Scalability- diminished size of data to be validated and transmitted across the network also translates in interesting capacity gains which results in transaction fee reduction ETA- Still a ways to go Schnorr is a massive project with many moving peices

Bitcoin will not store your data forever
 
07:25
People who believe that block size should be kept small often point at this as one of the main reasons: It goes like this: -------- Blocks are kept forever. Infinite storage time will always brings infinite people who want to fill this storage with their data. A fee paid once can be considered negligible, as the storage time is infinite. ( X / ∞ = 0 ) -------- This is a valid argument, but it relies on a false assumption. Blocks are immutable, but there is zero guarantee that they will be stored forever, or be accessible forever. In the bitcoin whitepaper Satoshi wrote about deleting old blocks when they are no longer needed. If people who fill the blockchain with trash data, they will end up storing these filled blocks on their own hard disk, because nobody else would store it for them.

#243 Izaak Meckler & Evan Shapiro: Coda – A Succinct Blockchain

Support the show, consider donating: BTC: 1CD83r9EzFinDNWwmRW4ssgCbhsM5bxXwg (https://epicenter.tv/tipbtc) BCC: 1M4dvWxjL5N9WniNtatKtxW7RcGV73TQTd (http://epicenter.tv/tipbch) ETH: 0x8cdb49ca5103Ce06717C4daBBFD4857183f50935 (https://epicenter.tv/tipeth) One of the key scalability challenges with public cryptocurrency blockchains is that their size grows linearly with the number of transactions. Mature blockchains such as Bitcoin and Ethereum contain 170GB and 1 TB of historical data respectively. New nodes joining these chains need to download this data and verify it in order to become a ""full node"". The number of full nodes is a key measure of decentralization, and difficulty becoming a full node translates into future centralization. In this episode, we are joined by the duo of Evan Shapiro and Izaak Meckler, CEO and CTO at O(1) Labs respectively. O(1) labs is a pioneering company that uses zkSNARK technology in order to construct a cryptocurrency blockchain, called Coda, that solves the blockchain size scalability bottleneck. New nodes joining the Coda network will be able to trustlessly boot up in under a minute by verifying cryptographic proofs that attest to the validity of the current chain. This technology has great potential to enable decentralization, and for one blockchain to be a light client of another blockchain. Topics discussed in this episode: - Scalability challenges of current cryptocurrencies - Background on O(1) labs and their mission statement - How Coda uses succinct computational integrity technology (zkSNARKs) to enable further decentralization of blockchains - Snarky - a domain specific language for zkSNARK computations - Current state of Coda and roadmap Links mentioned in this episode: - Coda protocol website: https://codaprotocol.com/ - Coda Whitepaper: https://codaprotocol.com/static/coda-whitepaper-05-10-2018-0.pdf - Presentation on Snarkly by Izzak Meckler: https://www.youtube.com/watch?v=gYn6mTwJriw - zkSNARKs in a nutshell by Christian Reitweissner: https://blog.ethereum.org/2016/12/05/zksnarks-in-a-nutshell/ - zkSNARKs in a nutshell by Vitalik Buterin: https://medium.com/@VitalikButerin/quadratic-arithmetic-programs-from-zero-to-hero-f6d558cea649 - Coda presentation from ZCon: https://www.youtube.com/watch?v=qCVACpgQSjo Sponsors: - Shapeshift: Buy and sell alt coins instantly and securely without a centralized exchange - http://epicenter.tv/shapeshift This episode is also available on : - Epicenter.tv: https://epicenter.tv/243 - YouTube: http://youtu.be/4AJKUGNwzZ0 - Souncloud: http://soundcloud.com/epicenterbitcoin/eb-243 Watch or listen, Epicenter is available wherever you get your podcasts.

How secure is 256 bit security?
 
05:06
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Thread for Q&A questions: http://3b1b.co/questions Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives a desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

Trimble Transportation Enterprise Solutions, a leading provider of enterprise software to over 2,000 transportation and logistics companies, and the largest data science organization in the industry, supports thousands of customers, cabs, and trailers on the road. The freight and transportation industry today relies on inherently manual systems, where spreadsheets and individual files are updated by each party every time a new action is required. This causes a lack of accountability and zero visibility into important data stored in file-based systems. Trimble has developed several blockchain-based applications to give its customers a better platform experience. They are now joining their ecosystem by bringing together a way to engage in a single unified platform. Trimble will unveil a new Transportation Management System as a Service, called Harmony, built on a blockchain architecture powered by Apache Kafka and Apache NiFi. Trimble has designed an architecture that leverages Hortonworks Big Data solutions, HDP, HDF and Machine Learning models to power up multiple Blockchains, which improves operational efficiency, cuts down costs and enables building strategic partnerships The platform provides visibility for all participants across the entire Pick-Pack-Ship and Order-to-Cash processes Apache NiFi acts as the key data ingestion/management layer that determines which data stays off-chain for advanced analytics and which data goes on-chain for complete immutability and auditability.

What information does blockchain record
 
01:15
Blockchain is the ledger of the Bitcoin network. Each block is like a ledger’s individual page. What’s recorded in it? Each block records data such as blockheader, transactions, transaction counter and blocksize. “Blockheader” contains everything else besides transactions: The hash of the last blockheader, ensuring the blocks’ chronological order; “Timestamp” records the time when the block is generated; “Nonce”, the number that all miners seek to find every 10 minutes; And difficulty, which determines how hard it is to guess the answer. “Transactions” records information such as the sender, receiver, transaction amount and sender’s digital signature. These are the main content in each block. “Transactions counter” is the number of transaction in each block. “Blocksize” represents the size of the data in each block. Currently, the maximum blocksize is 1MB. It is possible that the blocksize limit will increase in the future.

WHAT IS BLOCKCHAIN?
 
02:31
A blockchain is a digitized, decentralized, public ledger of all cryptocurrency transactions. Constantly growing as ‘completed’ blocks (the most recent transactions) are recorded and added to it in chronological order, it allows market participants to keep track of digital currency transactions without central record-keeping. Each node (a computer connected to the network) gets a copy of the blockchain, which is downloaded automatically. Originally developed as the accounting method for the virtual currency Bitcoin, blockchains – which use what's known as distributed ledger technology (DLT) – are appearing in a variety of commercial applications today. Currently, the technology is primarily used to verify transactions, within digital currencies though it is possible to digitize, code and insert practically any document into the blockchain. Doing so creates an indelible record that cannot be changed; furthermore, the record’s authenticity can be verified by the entire community using the blockchain instead of a single centralized authority. A block is the ‘current’ part of a blockchain, which records some or all of the recent transactions. Once completed, a block goes into the blockchain as a permanent database. Each time a block gets completed, a new one is generated. There is a countless number of such blocks in the blockchain, connected to each other (like links in a chain) in proper linear, chronological order. Every block contains a hash of the previous block. The blockchain has complete information about different user addresses and their balances right from the genesis block to the most recently completed block. The blockchain was designed so these transactions are immutable, meaning they cannot be deleted. The blocks are added through cryptography, ensuring that they remain meddle-proof: The data can be distributed, but not copied. However, the ever-growing size of the blockchain is considered by some to be a problem, creating issues of storage and synchronization.
