Solidity, Mapping & Gas

Gas is the cost of using the Ethereum platform. All update and computational tasks in any smart contract from deployment to usage consumes gas. This gas is then paid to miners of the blockchain, the guys behind updating the network. Becoming a coder who knows solidity and javascript is not enough. One should exercise caution

Grit for coding and life

What I’ve been trying to develop within my skillset is Grit for the past month a half. More commonly known as persistence, it enables successful athletes, influencers & leaders to punch through any obstacle no matter what. This is very important as a programmer in the blockchain space, where there are tons of problems to

Initiative: a real world solution for climate change using blockchain technology

Today I finished Initiative, a project included in my course for Solidity and Ethereum at Udemy and holds tons of potential. It allows one to become an Initiator and create an projects that can help people in need all over the world. But there is already kickstarter or indiegogo and why will we need another

The first of many projects in Ethereum..

I built a simple Ethereum project deployed to rinkeby network. It is part of my solidity course in Udemy and pretty proud of finishing it. The whole project taught me a lot of insights : Now I understand why Solidity programming is a strongly typed scripting language. Since blockchain technology essentially is a cryptographic database

Experimenting on Hyperledger

Scalability in Ethereum is a big issue now. Whatever DAPP (decentralized application) you design, develop and deploy to the main network, it will not be fast enough to serve customers as a limitation of the proof-of-stake validation of every block (less than a million per day). Though there is inherent value in learning solidity in

Scalability of blockchain technology is a major issue and it will definitely affect delivery of most ICOs

This is a very big issue now for the technology. As promising as decentralizing the world’s information and economics, scaling blockchain technology to reach mass market adoption is its biggest. Now, “Ethereum can only process seven transactions per second” which means that the maximum number of customers it can handle per day is only 604,800.

Can a stable coin create a one economy world?

I started to ponder around the idea of a universally accepted currency all around the world. As volatile cryptocurrencies like Bitcoin and Ethereum proved that blockchain technology allows verification of transactions, ultimately prevents hacking of accounts and accessible to anyone who has internet connection, the problems attached with the “economic attribute” of it is still

Crypto Valley of Asia? Toronto? London?

I fell in love with backpacking and travel after experiencing it in 2017. But realizing that I should focus on creating software projects will be my legacy, I accepted the fact that I would not be able to travel as much as I wanted for the rest of my life. It’s very easy to decide

The worst conditions for programming

I always believe in Benjamin Franklin’s words: “If you would not be forgotten as soon as you are dead and rotten, either write things worth reading, or do things worth writing.” I started learning programming after deciding that I will learn blockchain technology back in April in Calibangbangan Island, Linapacan, Palawan. After a year of

What is blockchain?

Most people think that bitcoin and blockchain are synonymous. It’s not the same thing. Blockchain is the technology behind bitcoin. Blockchain is a network of databases called “blocks” that contains either monetary value and / or information. These blocks have three key features: Data – Data represents the information about the transaction recorded. Hash –
