Monopolies and Proof of Stake with Karl Floersh

http://traffic.libsyn.com/sedaily/2018_03_12_MonopoliesandProofofStake.mp3Podcast: Play in new window | Download Decentralized applications might someday offer alternatives to modern monopolies. Uber, Airbnb, Facebook, Amazon—all of these services could be recreated on a decentralized stack of technologies like Ethereum, IPFS, and Golem. Fully decentralized services could be more transparent, cheaper, and more efficient. But let’s be realistic. Today, even the simplest applications of fully decentralized blockchains don’t work as well as we need them to.

Proof of Stake with Subhan Nadeem

http://traffic.libsyn.com/sedaily/2018_03_09_ProofofStake.mp3Podcast: Play in new window | Download For a decade, Bitcoin’s proof-of-work system has run without disruption. In a proof-of-work scheme, Bitcoin miners compete to solve a cryptographic puzzle associated with a block of transactions. Every ten minutes, all the Bitcoin miner nodes race to be the first to solve a block of transactions. Only one miner wins each block, meaning the other nodes’ time was ultimately wasted. There is

Smart Contracts with Raine Revere

http://traffic.libsyn.com/sedaily/2018_03_07_SmartContracts.mp3Podcast: Play in new window | Download Smart contracts are programs that run on the Ethereum blockchain. A smart contract developer pays Ether to deploy the contract. When a contract is deployed, every full node on the Ethereum blockchain has a copy of the contract code in that node’s address space. Every full node needs to hold a copy of every smart contract. This allows every full node to process

Blockchain Scalability with Peter Ullrich

http://traffic.libsyn.com/sedaily/2018_03_01_ScalingBlockchains.mp3Podcast: Play in new window | Download There are two factors that limit the rate at which transactions are accepted into the Bitcoin blockchain: block time and block size. Block time defines how often a new block is appended onto the blockchain. Block size defines how many transactions fit into a new block. As of March 2018, the current block time and block size allow for about 7 transactions per

Bitcoin Transactions with Daniel Van Flymen

http://traffic.libsyn.com/sedaily/2018_02_26_BitcoinTransactions.mp3Podcast: Play in new window | Download Bitcoin is an immutable, append-only blockchain ledger that reaches consensus through proof-of-work. The contents of the ledger are financial transactions–people sending and receiving Bitcoin currency to each other. Since Bitcoin, there have been other cryptocurrencies that have similar properties–like Ethereum and the IPFS/Filecoin system. Similar to Bitcoin, they use a decentralized, proof of work based system with a currency reward system–but the ledger

Cryptoeconomics with Vlad Zamfir

http://traffic.libsyn.com/sedaily/VladZamfir.mp3Podcast: Play in new window | Download A cryptocurrency has a distributed ledger called a blockchain. The blockchain keeps track of every transaction that occurs across the cryptocurrency. This blockchain must stay up-to-date and verified–which requires someone in the network to do that validation. Bitcoin and Ethereum use the proof-of-work algorithm. Miners do computational work to validate the legitimacy of transactions across the network, and in return they are given
