Blockchain Technology Explained Quotes

“Ethereum is the second-biggest cryptocurrency in the world after Bitcoin. It’s also very different from Bitcoin in its structure and purpose. Ethereum wasn’t developed as a currency alone. Its innovation lies in opening the blockchain up to development for different applications outside currencies and finance. Developers can build software on top of Ethereum’s blockchain, and use the network’s distributed ledger to build trust for all kinds of applications. Since the Ethereum blockchain is decentralized, once a developer has built an application, it can’t be censored or taken down by any authority. That application lives as long as the Ethereum blockchain continues.”

“The foundational idea behind institutions is creating trust between strangers in society. We have laws and systems in place to make it possible for millions of people who don’t know each other to live in proximity to one another. However, the creators of blockchain felt these institutions were failing.”

“Ethereum has become the go-to place to create new ICOs for a few reasons. First, the blockchain already exists and you don’t have to code a new blockchain from scratch. Second, Ethereum has a huge mining community and the second largest market cap of any cryptocurrency, making for a strong foundation for a new project. Finally, Ethereum has a clear set of guidelines for creating new tokens called the ERC-20 protocol.”

“2017 has been the year of ICOs. According to Bloomberg , ICOs have raised over $1.6 billion in 2017 alone. The explosion of ICOs is a result of the ease with which Ethereum permits the creation of new coins. With little more than an idea and a white paper, you can set up an Ethereum-based ICO and raise millions of dollars, circumventing the old-school fundraising channels of venture capital or seed funding from institutional investors.”

“a 55% increase in transaction volume in 2017. On the average day, the Bitcoin network processes 310,000 transactions . However, the network isn’t meeting demand. On any given day, there are tens of thousands of transactions that get put on hold waiting for the network to catch up to confirm them. These transactions are on hold because Bitcoin has a limit on its block size. Only so many transactions can fit in one block, so any that don’t fit have to wait. This waiting for confirmation is Bitcoin’s scalability problem, and it’s one that must be solved before the coin will be feasible as an everyday currency.”

“So the puzzle behind proof of work is to get the block’s hash to start with a zero [0...]. Eventually, if I keep adding nonsense characters onto the end of the block, I’ll eventually get a hash that starts with a zero. Once I do, I’ve solved the problem. The little bit of nonsense characters I had to place at the end? That’s the nonce.”

“Proof of Work In order to slow down attackers and guarantee blockchain security, there needs to be more honest verifiers on the network than dishonest attackers. In other words, since the blockchain is based on consensus, we need a system where people are rewarded for being honest and punished for creating false transactions. We also need to slow down block creation so that the whole network has a chance to verify transactions and certify new blocks before the next block is created.”

“Now comes a difficult-to-grasp concept: there is no such thing as a Bitcoin. Of course, there are no physical Bitcoins. You probably already knew that. However, there are also no Bitcoins on a hard drive somewhere. You can’t point to a physical object, digital file, or piece of code and say, “this is a Bitcoin.” Instead, the entire Bitcoin network is only a series of transaction records. Every transaction in the history of Bitcoin lives in the Bitcoin blockchain’s distributed ledger. If you want to prove that you have 20 Bitcoins, the only way you can do it is by pointing to the transactions where you received those 20 Bitcoins.”

“strength.The idea behind blockchain is to replace institutions with technology that can do the job better and empowers individuals. If you could create a way for strangers to trust one another without needing a bank or a government as an intermediary, you’d tackle one of society’s biggest bottlenecks.”

“assumption.Blockchain contracts and transactions take place on a shared network. The users on the network also pitch in to verify the transactions of others. Instead of a central authority charging a fee to verify your transaction, you verify another transaction on the network in exchange for your own transaction getting processed.”
