10 Biggest Blockchain Companies in the World 2025
This high ambition is part of the reason why OKX pursued and was granted our licence to provide crypto services in the emirate during July 2024. Whether it’s between people or organizations, relationships flourish when there’s more trust. From jewelry to insurance to food, IBM Blockchain can elevate that trust to an entirely new level. By helping parties who are transacting together validate and share immutable transaction records on a private, distributed ledger.
Put simply, EVDI allows users to verify the accuracy and integrity of data at every stage of its lifecycle — from its origins to final use. This allows users to confirm the data’s accuracy at any point and guarantee it remains unchanged. Through its EVDI, Empeiria aims to simplify the deployment of decentralized data ecosystems for AI-based organizations.
Any data stored on blockchain is unable to be modified, making the technology a legitimate disruptor for industries like payments, cybersecurity and healthcare. IBM is actively involved in blockchain development and offers various blockchain solutions for businesses. From supply chain management to financial services, IBM’s blockchain offerings cater to a wide range of industries.

For example, exchanges have been hacked in the past, resulting in the loss of large amounts of cryptocurrency. While the hackers may have been anonymous—except for their wallet address—the crypto they extracted is easily traceable because the wallet addresses are stored on the blockchain. For instance, the Ethereum network randomly chooses one validator from all users with ether staked to validate blocks, which are then confirmed by the network.
Industries
By utilizing blockchain technology, Bitfarms secures and validates cryptocurrency transactions while also contributing to the overall security and efficiency of blockchain networks. Put simply, blockchain is a technology that enables the secure sharing of information. A blockchain is a type of distributed database or ledger, which means the power to update a blockchain is distributed between the nodes, or participants, of a public or private computer network. Nodes are rewarded with digital tokens or currency to make updates to blockchains.
This immutability is part of creating transparency across the network and a trustworthy record of all activities on the blockchain. Meanwhile OKX’s General Manager in the MENA region, Rifad Mahasneh, noted the strength of Dubai’s retail and institutional trading audience, thanks in part to the emirate’s status as a regional financial hub. Mahasneh also pointed to the breadth of Dubai’s ecosystem, which brings together exchanges, brokers, insurance providers, and custodians, as another reason for Dubai’s appeal as a crypto hub.
Each block contains stored data, as well as its own unique alphanumeric code, called a hash. These cryptographically generated codes can be thought of as a digital fingerprint. They play a role in linking blocks together, as new blocks are generated from the previous block’s hash code, thus creating a chronological sequence, as well as tamper proofing. Any manipulation to these codes outputs an entirely different string of gibberish, making it easy for participants to spot and reject misfit blocks. One example is the role of Proof of Reserves (PoR) audits, which exchanges use to show that their capital holdings match their customers’ deposits one-to-one.
The other issue with many blockchains is that each block can only hold so much data. The block size debate has been and continues to be one of the most pressing issues for the scalability of blockchains in the future. Perhaps the most profound facet of blockchain and cryptocurrency is the ability for anyone, regardless of ethnicity, gender, location, or cultural background, to use it. According to The World Bank, an estimated 1.4 billion adults do not have bank accounts or any means of storing their money or wealth.
Other diamond producers and retailers have joined the effort, with the goal of implementing Tracr as an industrywide standard. Public perception of blockchain and cryptocurrencies, in particular, remains uneasy. As of 2024, 44% of Americans still say they will never purchase a cryptocurrency. Alternatively, there might come a point where publicly traded companies are required to provide investors with financial transparency through a regulator-approved blockchain Blockchain Solutions reporting system.
Since its induction into the mainstream alongside Bitcoin’s debut, the data management protocol has expanded beyond DeFi into its various industries across a wide-range of applications. One of the most important concepts in blockchain technology is decentralization. Blockchain nodes can be any kind of electronic device that maintains copies of the chain and keeps the network functioning.
As Mahasneh noted, we’re now the first global crypto company in UAE to offer AED banking rails for our retail and institutional customers. The Home Depot implements IBM Blockchain technology to resolve vendor disputes and improve supply chain efficiency. Xenea is seeking ecosystem partners to collaborate on expanding its blockchain infrastructure. Eligible project representatives can submit inquiries via the partner application form linked below. In a pilot cross-marketing initiative with Chat3, an early adopter of the Xenea blockchain, over 250,000 users were successfully directed to their service, resulting in notable activity levels. EY refers to the global organization, and may refer to one or more, of the member firms of Ernst & Young Global Limited, each of which is a separate legal entity.
