Show 4 - Proof Of Work

Please subscribe to listen in on future deep-dives. Next week: Attack of the 51% hash monster! Episode 4: Hey, I’m Not Lazy...I Even Have Proof of Work! What is Proof of Work? PoW is a protocol, or accountability system, that deters service abuses like denial of service attacks and spam. Hashcash is an early version of this technology, and is used in email systems, blogs, and other digital networks to deter spam attacks. In blockchain systems, the technology is inverted. The Proof of Work hash protocol is used as an enabling device to allow decentralized participants to transparently append blocks of transactions to an existing chain of prior transactions. The Bitcoin blockchain network, the first functioning “chain of blocks” as it is called in Satoshi’s whitepaper, employs a hash-based Proof of Work concept. What is a hash? Hashing functions take an input and produce an output. They are digital code that represent transactions, or a set of transactions contained in an informat...

Show 3 - What The Fork Is A Fork?

Digi B starts Show 3 with the most basic question: What the fork is a fork? The short answer is that when an existing blockchain is forked it creates two new chains at the block height of the fork. At the point of the fork, all transactions on that blockchain would occur on two separate chains. But before that split, the newly forked chain shares the history of all previous transactions made on the parent chain. Prof K approaches the question from a finance perspective. It’s free money! A fork can be well compared to a spin-off IPO of an unwanted subsidiary in the stock world. Some investors reinvest earnings from forked coins back into BTC, others accumulate a fat wallet of forked coins on the off-chance that maybe they will be as valuable as BTC one day. Mr. Lo brings the perspective of a developer. The word “fork” has multiple meanings in software development depending on the context. Most recently the term is an integral part of the process of social software development, a p...

Show 2 - Interview With Amal Sudama, Ethereum Developer

In our first interview-based show on BLOCK RUNNERS, we introduce our third co-host - Amal Sudama, an Ethereum developer. He believes that decentralization, both politically and data-architecturally, allows blockchains to be: - Less likely to fail because they rely on many separate components. - Harder to attack because the networks are spread across many computers. - Harder for users with malicious intent to take advantage of users who are using the platform for its intended purpose. - Hard-coded with a survival instinct that makes the blockchain very resistant to attacks. If one node stops working, or even 100 nodes, the blockchain survives, assuming there is at least one node up and running. - Resilient because the blockchain does not stop working even if the power is lost in an entire country, a feature which cannot be said of many of the existing systems we use on the Internet. Today, companies like Facebook, Amazon, and Google dominate the Internet. They offer many free or chea...
