What is blockchain technology?
Blockchain technology was announced through the paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" by Satoshi Nakamoto in 2008. Interestingly, this paper does not specifically use the word "blockchain". This paper talks about a "purely peer-to-peer version of electronic cash" where "the network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work".
Simply put, a blockchain is a peer-to-peer network which timestamps records by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work.
On the other hand, a distributed ledger is a peer-to-peer network, which uses a defined consensus mechanism to prevent modification of an ordered series of time-stamped records.
All blockchains are distributed ledgers but all distributed ledgers are not blockchains.
Blockchain technology has earned the trust and respect of banks and Governments around the world.
Blockchain technology derives its strength from strong cryptography. Blockchains are provably immutable and enable the rapid transfer and exchange of crypto-tokens (which can represent assets) without the need for separate clearing, settlement and reconciliation.
There are multiple blockchains and distributed ledger systems to choose from - BigChainDB, Chain, Corda, Credits, Elements, Eris, Fabric, Ethereum, HydraChain, Hyperledger, Multichain, Openchain, Quorum, Sawtooth, Stellar.

Blockchain pain points
- Installing, configuring, securing, troubleshooting, updating, and maintaining a blockchain ecosystem (base operating system, configured instance of a suitable blockchain fabric, external databases, webservers, FTP servers etc.) is a complex and time-consuming task.
- There are multiple blockchains and distributed ledger systems to choose from - BigChainDB, Chain, Corda, Credits, Elements, Eris, Fabric, Ethereum, HydraChain, Hyperledger, Multichain, Openchain, Quorum, Sawtooth, Stellar.
- Building blockchain solutions from the ground up is very expensive and time-consuming.
