In the quiet state of Salamia, nestled amidst rolling hills and lush forests, a new chapter was about to unfold. The residents of the state had long lived in the shadow of a previous regime that had left behind a legacy of misdeeds and mistrust. However, hope blossomed as a new chief minister, Naresh Pamnani, assumed power with a determination to rectify past wrongs.
Naresh was a visionary leader, armed with a keen intellect and a heart fuelled by justice. From the moment he took office, he had a clear goal in mind: to tackle the pervasive issue of land grabbing that had plagued Salamia for years. Rumours had circulated about the lands being unfairly taken from rightful owners, leaving families displaced and communities torn apart.
With a team of technologists, legal experts, and community leaders by his side, Naresh introduced an innovative solution to the age-old problem – a blockchain-based land registry system. This system aimed to ensure the accuracy, transparency, and immutability of land ownership records.
Initially the people of Salamia were sceptical. But Naresh was relentless in his pursuit of justice. He launched a grassroots campaign, visiting villages, holding town hall meetings, and listening to the stories of those who had suffered due to land grabs. His empathy and determination resonated with the people, and slowly, their scepticism began to wane.
The blockchain-based land registry system was rolled out with great care and meticulous planning. Every land parcel in Salamia was digitised and represented as a unique digital token on the blockchain. The state’s residents could access this decentralised ledger and verify ownership records themselves, eliminating the need for intermediaries and reducing the risk of fraud.
Smart contracts were introduced to automate land transactions. These contracts would hold funds in escrow until all conditions were met, ensuring that transactions were fair, secure, and free from manipulation. Community members actively participated in the process, ensuring that the system truly served their needs.
As the months went by, the impact of Naresh’s initiative became evident. Families were able to reclaim their ancestral lands, long lost to unscrupulous practices. Communities that had once been divided found themselves united by a shared hope for justice. The once-sceptical residents of the state now saw Naresh as a beacon of change, a leader who had turned their hopes into reality.
News of Salamia’s success story spread far and wide, inspiring neighbouring states and even cities to consider similar blockchain-based solutions for land management. Blockchain had woven a tapestry of trust, enabling a new era of prosperity and unity.

Ethereum on AWS
Ethereum’s versatility has led to its widespread adoption for various use cases, including decentralised finance (DeFi), non-fungible tokens (NFTs), supply chain management, identity verification, and more. However, as with any technology, it’s important to understand its capabilities and limitations before building or investing in projects on the Ethereum blockchain.
Key features of the Ethereum blockchain
Ethereum is a decentralised, open source blockchain platform that enables the creation and execution of smart contracts and decentralised applications (DApps). It was proposed in late 2013 by Vitalik Buterin and development began in early 2014, with the mainnet (live blockchain network) launched on July 30, 2015. The key features of the Ethereum blockchain include:
Smart contracts: Ethereum introduced the concept of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. These contracts automatically execute when specific conditions are met, without the need for intermediaries.
Decentralised applications (DApps): Ethereum allows developers to build decentralised applications on its platform. These DApps can serve a wide range of purposes, from financial services to gaming and more. They are typically open source and operate on the blockchain, providing transparency and security.
Ether (ETH): Ether is the native cryptocurrency of the Ethereum network. It is used to pay for transaction fees and computational services on the platform. It’s also often seen as a digital asset and investment.
Decentralised autonomous organisations (DAOs): Ethereum supports the creation of DAOs, which are organisations run by code and the consensus of their members. They can make decisions and manage funds autonomously, based on the rules defined in their smart contracts.
Consensus mechanism: Ethereum currently operates on a proof of stake (PoS) consensus mechanism known as Ethereum 2.0 (Eth2). This is an upgrade from the original proof of work (PoW) mechanism, which is still used in Ethereum 1.0. Eth2 aims to improve scalability, security, and energy efficiency.
EVM and Solidity: Ethereum introduced the Ethereum Virtual Machine (EVM), a runtime environment that enables smart contracts to be executed. Solidity is the most commonly used programming language for writing smart contracts on Ethereum.
Interoperability: Ethereum has supported the development of various standards and protocols, such as ERC-20 (fungible tokens) and ERC-721 (non-fungible tokens), which have contributed to the growth of the blockchain ecosystem.
Upgrades: Ethereum is continually evolving. Major upgrades are being rolled out to address scalability, security, and sustainability challenges.
It’s important to note that Ethereum, like other blockchains, requires participants (nodes) to validate transactions and maintain the network. This decentralised nature helps ensure security, censorship resistance, and immutability of the blockchain’s data.
In order to work with Ethereum on AWS, we may consider using Amazon Managed Ethereum (AME) or deploying our Ethereum nodes manually on AWS services such as EC2 instances or Kubernetes clusters.
Amazon Managed Ethereum (AME)
AME is a fully managed Ethereum service provided by AWS. It is designed to simplify the deployment and management of Ethereum infrastructure.
It allows the creation of Ethereum networks quickly without the need to manage the underlying infrastructure. We can use AME to deploy Ethereum nodes, interact with smart contracts, and build decentralised applications (DApps) on the Ethereum network.
Solution for land grabbing prevention
Blockchain technology, when used in conjunction with legal and societal reforms, can help mitigate land grabbing by increasing transparency, improving property record management, and enhancing trust. Let us see how Ethereum blockchain technology can contribute to the prevention of land grabbing.
Immutable land records: Ethereum’s blockchain offers immutability, meaning that once data is recorded on the blockchain, it is extremely difficult to alter or delete it. Land records stored on Ethereum can provide a tamper-resistant history of ownership and transactions, reducing the risk of fraudulent changes to land titles.
Transparent land registries: Using Ethereum-based smart contracts, governments or organisations can create transparent land registries that are accessible to the public.
Identity verification: Implementing a blockchain-based identity verification system can ensure that only legitimate property owners or authorised parties can initiate land transactions. This can reduce the chances of unauthorised land sales.
Smart contracts for transactions: Ethereum’s smart contracts can be used to automate and validate land transactions. When a transaction is initiated, the smart contract can verify the legitimacy of the buyer and seller, and ensure that all legal requirements are met before transferring ownership.
Timestamping and notarisation: Blockchain can be used for timestamping and notarisation of land-related documents, creating a provable history of documents related to land transactions.
Community involvement: Blockchain can facilitate community involvement and consensus in land management decisions. Community members can collectively validate and approve land transactions to prevent unilateral decisions that may lead to land grabbing.
Legal and regulatory frameworks: While blockchain can provide technical solutions, it must be integrated into a supportive legal and regulatory framework. Governments and authorities should recognise blockchain-based land records and transactions as legally binding.
It’s important to recognise that blockchain technology is not a silver bullet for preventing land grabbing. It should be part of a broader strategy that includes legal reforms, community engagement, and good governance practices. Additionally, blockchain systems should be designed with careful consideration of privacy, security, and scalability to be effective in land management.
