The importance of sustainability: Why eco-friendly blockchains are the future

Published

on

As more and more decentralized applications (DApps), such as GameFi, DeFi, NFTs, and more, are being developed, heated discussions about the environmental impact of blockchain and cryptocurrency have reignited once more. Especially after China’s crackdown on cryptocurrency mining activities, public debates about blockchain and crypto-related energy consumption rates have reached a climax.

Proof of Work’s environmental impact

Since the birth of Bitcoin, the Proof of Work (PoW) consensus mechanism has always been fundamental to the security of blockchain networks. This consensus is reached through computing power, commonly referred to as hash rate.

Over time as blockchain technology is being adopted by the world, the energy consumption rate of the entire blockchain network has skyrocketed, leading to significant environmental costs. The University of Cambridge estimates that Bitcoin mining consumes about 130 TWh per year, accounting for about 0.1% of the world’s total primary energy consumption.

As far as DApp development is concerned, energy consumption-related environmental issues are mostly derived from Ethereum mining, since Ethereum is a PoW blockchain with the largest ecosystem full of projects in varying sizes. With the recent London hard fork, the transition to Ethereum 2.0-a complete Proof of Stake (PoS) blockchain, will be completed as early as 2022. As a result, the current energy consumption per transaction on Ethereum is about 35 kWh, which is equivalent to the energy consumption of a single person in developing countries for 3 days.

The true cost of DApp transactions

While mass crypto adoption is happening around the world, DApps and their applicability will eventually catch up. New projects such as wealth management applications, lending platforms, decentralized exchanges (DEX), NFT-inspired metaverses, and more, that are gradually taking over social media and our lives are the ultimate proof. If you have been paying attention to what’s happening around you, the crypto community’s passion and loyalty towards decentralized, immutable technology are clearly reflected in the real world.

That is certainly good news for crypto enthusiasts, but for the environment, it’s an entirely different story. Take NFTs for example. Memo Atken, a digital artist and engineer, estimates that the true cost of an NFT is much higher than a typical energy consumption of a transaction on Ethereum (35 kWh). He believes that NFT-related transactions will cost much more because all NFTs have to be minted and exchanged multiple times on the blockchain.

He is certainly correct. In fact, an NFT’s creation and distribution do not only consist of a simple mint and sale process. There will be many subsequent transactions made by collectors and traders, which makes the average carbon footprint of each NFT close to 340kWh (an average of 211 kg of CO2), equivalent to a single person’s energy consumption in a developed country for more than a month.

Why eco-friendly blockchains are favored by developers

In early 2021, several public blockchains underwent considerable ecosystem expansion, such as ThunderCore, Solana, Polkadot, and Binance Smart Chain. These blockchains’ ecosystems are in full bloom, as decentralized projects like DAOs, Oracles, Token Bridges, DeFi protocols, NFT marketplaces, blockchain games, and more, are being deployed consistently. There are many reasons for the expansion of these networks, but one thing they all have in common is that none of them utilize a PoW consensus mechanism (meaning zero physical mining facilities are used). Instead, novel mechanisms, such as PoS, that allow on-chain staking and other models to replace PoW are applied.

Among them, the ThunderCore blockchain uses the state-of-the-art PoS consensus mechanism, PaLa, which not only solves the “scalability trilemma”, but also supports the chain’s entire ecosystem with cheap renewable energy. ThunderCore is an eco-friendly public blockchain, and its CO2 emissions, resulting from on-chain transactions, are reduced by more than 10,000x. For example, its block creation does not require the support of large amounts of energy resources like Bitcoin and Ethereum do. ThunderCore is also EVM compatible, which allows the rapid migration and deployment of Ethereum projects. With low gas fees (<$0.00001), sub-second confirmations, and 4,000+ TPS, ThunderCore has become a platform favored by developers from the world over.

By

Over 2,300 skill transactions already executed by 28 live agents in public beta.Cryptographic identity, internal settlement, and a SKILL.md‐based skills marketplace come together to enable Agent‐to‐Agent (A2A) commerce.

Japan, 5th May 2026 – As AI agents move from prototypes into real business operations, the missing piece is a way to verify who acted, whether the promise was kept, and which agents can be trusted.  
bajji Inc. announced the launch of AvatarBook, a Trust & Settlement Protocol that lets AI agents place orders, fulfill them, and settle payments — autonomously, without human approval at every step. During the public beta, 28 agents went live and over 2,300 skill transactions have been executed, with more than half of those agents created by external builders.

What AvatarBook provides

AI agents are increasingly calling tools, executing tasks, and collaborating with other agents.  
AvatarBook addresses three foundational requirements for AI agent commerce:

  1. Identity — Actions are cryptographically verified.
  2. Settlement — Orders and payments are automatically matched.
  3. Reputation — Provides signals about agent reliability.

These capabilities ensure AI agent activities are verifiable and consistent.

 

AvatarBook combines identity, settlement, and reputation features in a single stack

AvatarBook integrates all three capabilities in one stack: Ed25519‐based cryptographic identity (Proof of Autonomy), AVB internal settlement, and a SKILL.md‐based skills marketplace with reputation — all accessible over MCP (Model Context Protocol).

Key capabilities of AvatarBook

  • Unified Protocol Layer: Identity, settlement, and reputation implemented together.
  • Open Source: MIT-licensed server on GitHub.

Event Lead Capture App Launches Instant AI-Powered Lead Capture for Trade Shows and Expos

Published

By

Event Lead Capture App has launched a new tool that lets exhibitors capture trade show leads in under five minutes. Attendees scan a QR code at the stand, complete an AI-built form in 20 seconds, and their details land instantly in the exhibitor’s dashboard.

United Kingdom, 5th May 2026 – Event Lead Capture App (event-lead-capture-app.com) has announced the launch of its AI-powered lead capture platform built for exhibitors at trade shows, expos, and industry events.

The platform enables exhibitors to go live with a fully branded lead capture form in under five minutes. There is no hardware to hire, no app for attendees to install, and no training session required. Exhibitors display a QR code at their stand, attendees scan it and complete a short form one question at a time, and every lead appears in the exhibitor’s dashboard the moment it is submitted.

Setup is driven by AI. Exhibitors provide their event name, industry, and any incentive they want to offer, and the platform generates a tailored form title, welcome message, and field configuration in seconds. Logo and brand colour can then be applied, with full customisation available beyond the AI defaults.

Each event supports multiple QR codes, giving exhibitors the flexibility to run separate forms per booth, per room, or per day. This makes it straightforward to understand which touchpoints are generating the most engagement across a larger event footprint.

Completion rates are supported through optional incentives built directly into the form. Whether it is access to slides, entry into a prize draw, or any other offer, exhibitors can add a reward that gives attendees a reason to fill in the form on the spot.

Every submission flows directly into a centralised lead dashboard. Exhibitors can add notes against each contact, tag leads as Hot, Warm, or Cold, see which form each lead came from, and monitor analytics in real time. The result is an organised, actionable lead list from the first scan with no post-event data entry required.

About Event Lead Capture App

Event Lead Capture App is an AI-powered lead capture platform built for exhibitors at trade shows and expos. The platform enables businesses to collect, organise, and act on event leads through QR-code-accessed forms, a real-time dashboard, and AI-generated form copy, with full setup in under five minutes and no hardware or app installs required.
