A pioneering feature of Bitcoin is verifiability of transactions: It is designed to enable low-power devices and high end computers alike to be able to verify occurrences on the blockchain.
This observation led our guest, Adam Gibson, to wonder why webpages aren't so easily verifiable as a Bitcoin transaction? Can I prove to you that I have certain bank account balance over the internet? Why do we submit photocopies of passports rather than furnishing a cryptographically verifiable proof ...Read More

A typical online transaction today isn't very different from how it was done 25 years ago at the dawn of the Internet. In fact, online payments haven't changed much at all. When we want to pay for something online, we copy very sensitive credit card information into a form on a website and trust that website to capture it securely and make proper use of it. If this seems like an old and antiquated way to pay, that's because it is, and it costs billions of dollars per year in security and fra...Read More

In the midst of the heated blocksize debate one could be forgiven to think that there is very little Bitcoin developers are able to agree on.

Eric Lombrozo, CEO of wallet company Ciphrex and responsible for running the segregated witness testnet, joined us to discuss...Read More

Zero Knowledge Proofs are methods of providing cryptographic proofs to another party while keeping some information secret. The simple concept of ZKP offer tantalizing possibilities: Banks could prove solvency without revealing depositors. Governments could prove the fairness of an election without compromising privacy.
Computer science professor Eli Ben-Sasson joined us to discuss where blockchains and cryptocurrencies intersect with Zero Knowledge Proofs and related technologies such as...Read More

The idea that in the future tokens will play a crucial role in networks and organizations to incentivize decentralized collaboration and reward contribution is not new. It's the original decentralized autonomous organization idea that has informed many projects that have been on the podcast (Swarm, Ethereum, Factom, Storj, etc). For Matan, the vision originally led to found decentralized ride-sharing application LaZooz. One year ago, he left LaZooz to found Backfeed, which is building the to...Read More

As blockchain technologies mature, new protocol specifications are emerging, which take unique approaches to software design and how consensus is achieved. We have talked about Multchain and OpenChain in the past, but Tendermint promises to be a viable solution for many permissioned blockchain use cases. It’s design is modular, meaning that the application layer (smart contract) and the consensus laye...Read More

Permissionable blockchains have gained much attention from enterprise this past year, and specifically, the traditional fiance and FinTech sectors. As new protocols emerge and the technology is matures, it is becoming apparent they are simply a new class of database, one which integrates business logic (smart contracts) and a consensus layer (PoS, PoW, etc).
Casey Kuhlman is the CEO of Eris Industries, a company which specializes in building permissioned blockchain systems for enterprise...Read More
