8. Scalability:

• Concerns: Blockchain scalability concerns are acting as one of the

blockchain adoption barriers.

• Recommendations:

⚬

⚬One of the concerns for blockchain adoption is for the technology to

be scalable like existing use cases such as payments or supply chain.

⚬

⚬Although there are multiple start-ups working on highly scalable

technology and platforms to support scalability, we are not there yet.

⚬

⚬My recommendation is to monitor the technological trends within

blockchain closely.

⚬

⚬Another recommendation is to start small on existing single customer

journeys and be ready to expand whilst the technology is improving.

9. Performance

• Concerns: Blockchain performance issues are also one of the concerns

for blockchain adoption.

• Recommendations:

⚬

⚬As discussed in the previous point about scalability concerns, per-

formance concerns are also key factors that are slowing the block-

chain adoption.

⚬

⚬Again, various start-ups are working on updating the technology

to improve the performance.

⚬

⚬Some of the recommendations and various technological improve-

ments being worked on are listed below:

– Establish data models to be stored on blockchain DLT (distrib-

uted ledger) as well as off-chains or sidechains that can be utilised

– Use front-end distributed applications, which will be utilising

blockchain, as microservices

– Effective use of messaging queues

– Use scalable and high-performance storage for blockchain DLT

– Use scalable and performant infrastructure hosting the block-

chain. For instance, use Kubernetes to host microservices that

use vertical and horizonal auto-scaling

– Make use of sharing to store the data

10. Interoperability

• Concerns: Interoperability amongst different blockchains is a key

issue for blockchain adoption on mainstream production use.

• Recommendations:

⚬

⚬There are multiple different blockchains, products and silo com-

panies supporting them.

⚬

⚬Some of the products are open source or commercial.
