  • Factom - Big Data on the Bitcoin Blockchain - BnkToTheFuture Case Study

    http://bit.ly/1AJOQiZ Ever wondered what it would be like if you couldn’t prove your home, or even the land it’s built on, was actually yours? Ever pondered what happens to your data when you share it online, with your bank or with your government? At Bank to the future we believe that important records and data should be in your control, secure from hackers and stored in a way it cannot be tampered with. Well, you’ll be glad to know that these problems will soon become history. Factom developed technology to tackle these issues and chose to raise part of their funding on our Online Investment Platform - BankToTheFuture.com Unlike many companies, Factom believes that data should never be stored with one organisation. It is simply too attractive a target for hackers. Unlike banks,...

  • The Bitcoin and Blockchain Technology Explained

    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. 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 d...

http://bit.ly/1AJOQiZ Ever wondered what it would be like if you couldn’t prove your home, or even the land it’s built on, was actually yours? Ever pondered what happens to your data when you share it online, with your bank or with your government? At Bank to the future we believe that important records and data should be in your control, secure from hackers and stored in a way it cannot be tampered with. Well, you’ll be glad to know that these problems will soon become history. Factom developed technology to tackle these issues and chose to raise part of their funding on our Online Investment Platform - BankToTheFuture.com Unlike many companies, Factom believes that data should never be stored with one organisation. It is simply too attractive a target for hackers. Unlike banks, Factom believes that customers should only share their important information as and when it is needed. Unlike governments, Factom believes that important records should be stored in a tamper proof way, transparently and impossible to be altered. ...and we agree. BnkToTheFuture.com is the largest Online Investment Platform with thousands of professional investors waiting to invest in Financial and Technological innovation. Go to our homepage and you’ll get to see the total number of professional investors, how much they have invested, and the amount of dividends that they’ve received. Factom was a perfect match for us. They had built technology that stored huge data on the Bitcoin Blockchain secure from hackers, scalable and in a way that can never be tampered. They had already funded the development of the not-for-profit side of their technology by issuing their own CryptoCurrency, but were now ready to fund the for-profit side of their business. They secured a partnership with MicroSoft, a contract to build smart Cities in China and an initial agreement to build a proof-of-concept product to store land title deeds for a government. They wanted funding from professional investors who believed in them and knew the value of their business. and they wanted the investment to come through fast, in different currencies and with a streamlined compliance and documentation process. A solution was found, and Factom decided to list on Bank To The Future. We gave Factom access to a global community of thousands of qualifying investors ready to invest in Financial and Technological innovation. We gave them a platform that complies with international financial regulations tailored for most major currencies and countries. We structured the investment in a way that meant they only get one registered investor. We cut out the painful admin, legal costs and problems raising further finance in the future, as compliance and documentation was completed by us in an optimised investment structure. And all under a “no win, no fee” agreement with no up-front costs. We provided all our investors with one investment agreement and a forum to communicate with the team quickly, efficiently and privately with additional investor protections. Investors can download all legal work, due diligence and certificates via our platform whenever they want. We also invested in Factom through one of our Venture Capital funds - Bitcoin Capital, meaning, investors got to co-invest with us on the same terms and our interests are aligned. If Factom floats on a stock market, is acquired in the future or pays investors dividends, investors get their returns minus our 5% fee. We built our Online Investment Platform with one purpose in mind - to prepare for a radically different future in Financial and Technological Innovation... Businesses just like Factom can raise finance in a safe, fast and effective way, while our investors get to allocate a portion of their wealth to an extremely disruptive and fast growing area that many are beginning to see could change the world of finance - FOREVER! Just like Factom, you can get involved by making a quick online application for finance at BankToTheFuture.com or register to see if you qualify to invest. http://bit.ly/1AJOQiZ

Simple slideshow about blockchains work. This was created as an educational tool by Emma Stamm (@turing_tests / www.realyou.me). Apologies that the slides are so short -- the YouTube slideshow creator only allows images to be shown up to ten seconds! Some notes: I use the terms "hash" and "proof of work" interchangeably here. When I say "a new hash is generated based on the prior hash," I mean that the new hash is formulated using data from the hash that precedes it. Satoshi Nakamoto's white paper "Bitcoin: A Peer-to-Peer Electronic Cash System" is available here: https://bitcoin.org/bitcoin.pdf There is a lot more to blockchain/Bitcoin than this: this is a very rudimentary introduction. *** Transcription of the voiceover: Slide 1: What is blockchain? This is a very simple description of how blockchain works. Slide 2: Blockchain is a structure for the transmission of data. Any form of data, like a currency unit, a text document, an audio file, and so on. Slide 3: When a piece of data is entered onto a blockchain, all of the computers on that blockchain's network validate the fact that it's there. Slide 4: The validation happens using an algorithm that generates another unique piece of data, known as as a hash or proof of work that's applied to the original piece of data. . Slide 5: All of the computers on the blockchain work together to create the hash, and only when they agree on what it is does it get applied to the data. [Note: I don't say it out loud, but I included in the slide the fact that this process is known as "reaching consensus"] Slide 6: The original piece of data, plus the hash or proof of work, create what's known as a block. Slide 7: Every time that piece of data moves to another party, like when you make a payment with Bitcoin, a new hash is generated based on the prior hash & a new block is made. Slide 8: The blockchain's mechanism prevents data from being copied as it moves along the chain. This makes it great for finance, since it means people can't copy and double-spend currency units. Slide 9: Every computer on a blockchain can see all of the activity on the chain, going back to the first block. This is really important! Slide 10: This is why it's known as a distributed ledger: it's a record that everyone on the blockchain's network can view. Slide 11: Blockchain was developed to power Bitcoin, but it can be used for all sorts of things, like voting, verifying identity and selling content.

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. 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.
