Scalability is a common issue among the most used permissionless blockchains, and several approaches have been proposed to solve this issue. Tackling scalability while preserving the security and decentralization of the network is a significant challenge. To deliver effective scaling solutions, Ethereum achieved a major protocol improvement, including a change in the consensus mechanism towards Proof of Stake. This improvement aimed a vast reduction of the hardware requirements to run a node, leading to significant sustainability benefits with a lower network energy consumption.

Once the operational life of electronics component is over, it becomes part of electronic waste (e-waste). Afterwards, it is either dumped in landills or recycled for metallic constituents. Landills, in long run, are proven hazardous. Recycling approach also leaves a signiicant energy footprint on environment. This article presents a brief insight into the harmful impacts of the e-waste. Primary aim of this work is to justify the importance of adjusting new technology according to the conventional one so that the working components from the obsolete technology can be utilized optimally.

<p>Avatars are the alter-egos of users in Social Virtual Reality (SVR). They enable embodied interaction, preserving a wide spectrum of non-verbal and verbal communication cues in real-time, independent of users’ physical location. Avatar's appearance is highly variable as it spans from non to little human-like cartoonish forms to photorealistic replicas of real persons, leading to a wide range of potential effects other’s digital appearance has on the interpersonal relations established during an interaction.
