Exploring Metaverse using: Spatial.io
Imagine how it will feel if you will be able to attend any virtual event by creating various different digital “avatars”?
Metaverse is the key to this opportunity. In simple words, the metaverse can be defined as the 3-D network of the virtual world which focuses on social connection using augmented reality (AR) and virtual reality (VR).
In this blog we will be exploring Spatial that will help us to create our own “avatar” and our own personal virtual space.
Spatial.io is dedicated to helping creators and brands build their own spaces in the metaverse to share culture together. Spatial empower their users to leverage their beautiful spaces to share eye popping content, build a tight knit community, and drive meaningful sales of their creative works and products. Spatial also empower our users to create beautiful and functional 3D spaces that they can mint as NFTs and sell/rent to others looking to host mind blowing experiences.
Implementing meta transactions in your smart contract using Biconomy SDK
A meta-transaction can be defined as the way that allows the user to interact with the public blockchain without paying any transaction fee.
A meta-transaction is a general Ethereum transaction containing another transaction, the actual transaction. The actual transaction is then signed by the user and then sent to an operator or something similar which means no gas and blockchain interaction is required.
In order to perform meta-transactions, a user needs to sign a message. After a user signs it, DApp (Decentralised Application ) sends the message to a relayer who sends that message into an actual transaction to a public node so the transaction can be mined. more
