BLOCKCHAIN FOR NEWBIES
This is going to be a basic introduction to elliptic curve cryptography. I will assume most of my audience is here to gain an understanding of why ECC is an effective cryptographic tool and the basics of why it works. My goal is to explain it in a general sense, I will be omitting proofs and implementation details and instead focusing on the high-level principles of what makes it work.
I’ve noticed that some community members tend to attach a certain degree of cachet and mystique to the term “core developer.” I suspect that it has something to do with cognitive biases such as confirmation bias and with human tendencies such as apophenia, the tendency to see patterns and connections where there are none. Together these tendencies cause some people to view core developers as somehow different, special, or all-powerful — and in the extreme case, to imagine that they comprise some sort of secret cabal that makes backroom decisions affecting the protocol. As nothing could be further from the truth, I’d like to attempt to set the record straight and demystify the occupation.
This article documents the process of deploying a Smart Contract on the Ethereum Blockchain with Infura. Infura is a convenient tool for Smart Contract developers who do not want to run their own nodes.
Today we are going to go deeper into the world of smart contract vulnerabilities, focusing on an interesting weakness which came into prominence because of Ethereum-based auction game. This attack happened because of misallocation of gas.
As the cryptocurrency industry matures and public interest heightens, blockchain research and educational efforts have made their way into the halls of some of the world’s leading universities. Courses on cryptocurrency finance, blockchain development and related law are developing into serious avenues of study.
EOS contrary to Ethereum comes with the token smart contract out of the box. As Ethereum has ERC20 smart contract, EOS has eosio.token smart contract. Eosio.token smart contract allows you to create your own token by providing maximum supply and token’s literal, issue tokens to an account and transfer tokens between accounts. EOS tokens on EOS blockchain are issued using the same contract.
