NOTE: This is just my imagination without doing any proper research either on the problem statement or on the protocol. I request you to read this blog keeping that in mind. This is NOT full proof solutinon. Applications share data with each others via APIs. Sometimes, these APIs need to protected behind paywall by the API providers. This is to ensure APIs consumers do not misuse APIs as well as to incure cost of the API services.

Staking The x/staking module handles operations related to staking. Let’s undestand Staking modules with an account being made as a validator and then perform operations related to modules. Creating a validator hid-noded tx staking create-validator --amount=5000000uhid --from=node1 --pubkey=$(hid-noded tendermint show-validator --home=$HOME/.hid-node) --moniker="node1" --chain-id="hidnode" --commission-rate="0.1" --commission-max-rate="0.2" --commission-max-change-rate="0.05" --min-self-delegation="5000" --keyring-backend=test --home=$HOME/.hid-node --yes Here, we have user with account name node1. The user becomes the validator by staking 5000000uhid in the chain. We can the node1 being created as a validator

Building a UX where a User feels comfortable in interacting with the blockchain is much needed. In this blog, we will be looking at how the authz and feegrant Cosmos SDK modules aim to build a similar User Experience. The authz module grants and revokes permissions to accounts for performation certain transactions. This could be token trasnfer, staking.

We are quite familiar with what inflation is in real life. When the supply falls short of demand, the cost of goods and services increase, thus inflation. You can read more about inflation here. But what does it really mean in the world of Cosmos? Unlike real world, Inflation in Cosmos refers to the increase in minted tokens for each block, which are used to incentivize the stakeholders. Cosmos SDK allows us to set the parameters for initial inflation rate and the paramters related to it.

When it come to startups, its even more challenging since startups work on “fail-fast” approach which usually has resource crunch and grows exponentially (at least in the initial phases). You don’t even realize how soon the product gains 10k users from 1.

Introduction Social logins like Facebook, Google are common Single Sign-On (SSO) mechanisms for authentication in websites (also called service providers) these days. The social login helps service providers to quickly onboard a user without requiring them to go through the registration process.

Abstract The consumer-facing applications are more vulnerable for data breaches as they have a large customer base and they usually stored the user data in a central location. The consumer-facing app provider often has to choose between security and usability and they end up giving priority to the later one as usability become important growth factor. That allows a hacker to steal user data. In this blog, we are going to talk about problems, challenges which service providers face, especially with respect to user data protection and privacy, and what could be possible ways to solve that problem.
