Description

Block Shots is a podcast for blockchain beginners that provides a basic understanding of the most important blockchain concepts in five minutes. Learn blockchain, consensus, hashing, signing, governance, nodes, etc. and many more concepts while having that morning coffee, or while walking towards your car in the parking, or whenever you have those five minutes. Episodes are published weekly on Mondays.

Block Rewards

Block Rewards

2020-08-0304:48

Block rewards are a way to incentivize the nodes for creating new blocks and contributing to the decentralization and security of the blockchain.
Blockchain economics - what, why, and how. Block rewards, incentives, transaction fees, cryptocurrency supply, and demand.
Just like a car is just an application of a four-wheeled vehicle, Bitcoin is an application of blockchain.
Block Finality

Block Finality

2020-07-1304:59

The finality of a block means that the majority of the nodes in a blockchain network have verified and accepted that block and their state has been updated accordingly.
Fork

Fork

2020-07-0604:32

When some of the nodes decide not to update to the new rules, then a fork happens on the chain. Forks are of two types - soft and hard.
Blockchain Governance

Blockchain Governance

2020-07-0204:54

Blockchains are decentralized systems. There is no single point of control or administration. In contrast to other IT systems, there is no admin in a blockchain. Instead, blockchains are governed.
Blockchains, depending on who can read the state and who can participate in block production (updating the state), could be classified in mainly two ways - Private or Public, and Permissionless or Permissioned.
Applications which use a decentralized backend (like a blockchain), are called Decentralized Applications or DApps.
Smart Contracts

Smart Contracts

2020-06-2204:45

Smart Contracts allow users to add business logic to blockchains to make them useful for several business use-cases.
Wallets

Wallets

2020-06-1804:47

A blockchain wallet is a software program or a hardware device that could be used to store cryptographic keys.
Accounts and Keys

Accounts and Keys

2020-06-1504:43

Accounts are a way of representing users on the blockchain. In a blockchain, accounts are generally a representation of a user's keys.
Block Production is the process of proposing and appending new blocks to the blockchain so that the state of the chain could be updated.
Signing

Signing

2020-06-0805:14

Signing is the process of associating your identity with information so that it could be verified that the information is coming from you.
Hashing

Hashing

2020-06-0404:42

Hashing is the process of deriving fixed-length strings from arbitrary-length data.
Transactions are used to propose an update to the state of the blockchain. Blocks are groups of transactions.
Blockchain node software running on a physical or virtual machine and accepting connections is a blockchain node.
Consensus

Consensus

2020-05-2505:10

In the context of blockchain, consensus is the agreement on the state of the blockchain among all the nodes in a network.
Blockchain
