While billions of dollars are being spent on blockchain, and that spending is expected to grow exponentially over the next five years, the distributed ledger technology will never spark a technology revolution in the enterprise where preference always favors centralized control.
"I don't think we will ever see a revolution in the enterprise," said Avivah Litan, a vice president of research at Gartner. "No one wants to give up authority. Think about it. It goes against an enterprise's ability to control their own destiny. Full, complete blockchain is about no central authority. It's just peer-to-peer."

Litan was among analysts discussing tech trends shaping the future of IT and business at Gartner's IT Symposium/Xpo 2019 this week. Among the hotter topics was blockchain, which currently is sliding into the " Trough of Disillusionment ," from which it won't begin to emerge for at least another two years. Gartner

Still, enterprises are eagerly exploring blockchain, according to Gartner, because C-level executives and IT managers see it as something truly innovative. And they're trying to figure out how to use it, regardless of whether they actually need it.
"We have come across many companies who really want to explore blockchain but don't have appropriate use cases for it," she said. "It's hard to tell people they don't have a real use case for it. The users don't really understand what blockchain does or doesn't do . They just know they want to use it." Gartner
It will likely take another nine or so years before blockchain becomes fully scalable technically and operationally, according to Gartner. "Blockchain technologies have not yet lived up to the hype and most enterprise blockchain projects are stuck in experimentation mode," Litan said.
By 2021, 90% of current enterprise blockchain platform implementations will require replacement within 18 months to remain competitive, secure and to avoid obsolescence, according to Gartner.
For blockchain to reach its potential as a distributed ledger for global business-to-business transactions, five things need to happen: Smart contracts must become simple to code and test to ensure they don't have bugs and can be ported across various blockchain platforms. Smart contracts must be able to easily integrate with legacy enterprise systems, e.g. data "oracles" or APIs that connect blockchain to external data sources. Blockchain interoperability must become standardized so various platforms, such as Hyperledger, Ethereum, R3 Corda and others can communicate with each other. Blockchain must scale to compete with current financial transactional networks that can handle thousands of operations per minute. Privacy services based on zero-knowledge proof concepts and private key management must also mature and develop methods that allow users to recover lost pass codes.
Private key management is seen as the Achilles' heel of blockchain technology, Litan said, referring to the fact once a user loses their private key they no longer have access to the data, cryptocurrency or other assets connected to the latter.
A number of companies and consortiums are currently working to solve the private key problem as well as the scaling issue .
When blockchain's core-enabling technologies and use cases evolve and mature, the result will be significant benefits for enterprises, including blockchain and IoT integration, decentralized web apps and blockchain user interface technologies and blockchain managed services.
Managed services today include Chainstack , IBM's blockchain cloud , and Mangrovia Blockchain Solutions . The services allow organizations that lack technical expertise and infrastructure to support their own blockchain applications running in the cloud.
Also key to blockchain's success will be its evolution into a combination of a permissioned or private platform and an open, public ledger . That, Litan said, will enable enterprises to communicate privately and behind the scenes on a permissioned ledger, while also enabling a public-facing application that allows users to securely view transactions.
Hedera Hashgraph is one example of a "hybrid" distributed ledger. The startup is a competitor to both permissioned blockchains such as Hyperledger and public platforms (such as Hyperledger Fabric & Sawtooth, R3 Corda, and others) and their commercial providers, which include AWS, IBM, Microsoft, Oracle.
At its mainnet launch in August , the Hedera Hashgraph claimed it could outperform both public blockchains and traditional financial and business networks.
Hedera Hashgraph is very important. It's not a blockchain, but a blockchain equivalent with a lot of investment from different par...
