The need and applications for side chains vary greatly, but Aelf is building an entire infrastructure that allows businesses to customize their chains depending on needs. Financial, insurance, identity and smart city services are a few applications which need their own side chains. Interoperability between those chains is critical. Aelf is paving the way for a new internet infrastructure.
“Such brazen theft would indicate [1] that Bitcoin would be (in the near future) without sidechains of any kind, and [2] that Bitcoin itself may be in danger from the miners (and we may need to consider using an alternate proof-of-work hash function),” he explained the impact of this setup in his original post on the topic. Like SPV sidechains, drivechains require a soft-forking change to Bitcoin.
Sidechain is a blockchain that runs parallel to the main blockchain. It extends the functionality of interplorable blockchain networks. Interpolable blockchain networks signifies the ability to share data between different computer systems on different machines. It means that data can be sent and received between interconnected networks eliminating the possibility of negative impact to the networks. Sidechain enables this to be done in a decentralised manner to transfer and synchronise tokens between two chains.

Our Proof of Work tutorial talks about it in depth, but the best explanation might come from Satoshi Nakamoto himself. If the camps above start receiving messages that don’t agree, they rely on executing a Proof of Work. The Proof of Work is sufficiently complicated and requires significant computing power. Once one camp solves the Proof of Work, it broadcasts the results to the other camps. This message is now accepted in a chain of messages and the competing messages are dropped by the other camps.
Pegged sidechains employ a two-way peg to transfer assets between chains, and they consist of providing proof of possession in the transferring transactions. The idea is to enable the capability of locking an asset on an original parent chain, which can then be transferred to a sidechain before eventually being redeemed on the original chain. Notably, the original asset on the parent chain is locked in a specific output address and is not destroyed like early implementations of sidechains.
Blockchain technology can be used to create a permanent, public, transparent ledger system for compiling data on sales, tracking digital use and payments to content creators, such as wireless users [65] or musicians.[66] In 2017, IBM partnered with ASCAP and PRS for Music to adopt blockchain technology in music distribution.[67] Imogen Heap's Mycelia service has also been proposed as blockchain-based alternative "that gives artists more control over how their songs and associated data circulate among fans and other musicians."[68][69] Everledger is one of the inaugural clients of IBM's blockchain-based tracking service.[70]
@Tradle. Thanks for elaborating. I’m also thinking about these things – and hear lots of other people talk about them – but I *really* struggle with the concept. It all comes down to the table I drew in this post: https://gendal.me/2014/12/19/a-simple-model-to-make-sense-of-the-proliferation-of-distributed-ledger-smart-contract-and-cryptocurrency-projects/
