    Walking Tree Technologies

    Blockchain is ever evolving and hence its almost impossible for a person or organization to keep update on everything happening in this space. This series of meetups is a unique in a way that there won't be one person talking but everyone can bring something that they have learnt in the last one month, bring any questions, concerns, suggestions etc., so that the community can vet your ideas or concerns and iron out things. Once we meet for a couple of times, and that we have consistent show ups, we can plan further how to go from there on. We will setup our goals through the Nov 3rd 2018 meetup. Feel free to fork this meetup repo, add anything that you want to discuss in the meeting and place a pull request. https://github.com/moinuddin14/blockchain-meetup-notes Any suggestions are most welcome. :) Jan 5th Meetup Details & Agenda 1.

  • Upgradable Blockchain Smart Contracts using ZeppelinOS

    Walking Tree Technologies

    Smart Contracts immutability has taken the Blockchain to the whole new level, with trustless systems now can be trusted. But it also has brought huge complexities and risk involved with investor money. A Smart Contract once deployed is immutable, so whenever a hack happens, it's almost impossible to fallback or retreat with a patch and many a times its not likely that an action can be propagated immediately to all. We have seen many hacks, majorly DAOHack that has shaken the Crypto from the ground up. While all this was happening, a company called Zappelin was working under the radar on a concept called Upgradable Smart Contracts. It's not the only product they have, they also have extreme community vetted Smart Contract libraries. But, Upgradable Smart Contracts is a revolutionary thought and product that will change forever the way we see and work with Smart Contracts. We can say, its the future now product. Let's meet to discuss what is Upgradable Smart Contract and how it solves the current existing problems around immutable Smart Contracts.

  • Create Escrow Smart Contract

    Virtual Meeting

    Hi Friend, In this webinar, we will be creating a very simple Smart Contract i.e., escrow Smart Contract. Following is the use case. 1. Seller will place an item for sale 2. Buyer can purchase the item and the amount will be held in escrow in the smart contract 3. Buyer will confirm the receipt of the item 4. Amount will be released to Seller We are going to create this Smart Contract with an assumption that Buyer is a genuine person and don't have any malicious intentions. Once the webinar is done i will commit the entire code to this location https://github.com/moinuddin14/escrow-smart-contract-demo and you can fork and expand further with other features like 1. Buyer can be malicious user 2. Introduce another user as arbitrate 3. Create User Interface and interact with the Smart Contract Let me know more use cases that you feel can be added and i will add here, so that anyone can expand this code.
