Cardano [ADA] is slowly stealing the spotlight with multiple upgrades, a lot of test net launches, wallet releases, Paper submissions, conferences and summits, and social service with their technology. They are most popular for their research and development team and one from there, Dionysis Zindros has created a website that describes interactive proofs of proof-of-work. The researcher explains the entirely new concept called the non-interactive proofs-of-work [NIPoPoWs] through a post.
NIPOPOWS, their uses, sidechains, and support:
NIPOPOWS are short stand-alone strings that allow a computer program to inspect for the verification process for the occurrence of an event on a proof-of-work-based blockchain without being connected to the network and without downloading all block headers. These proofs can illustrate a cryptocurrency payment. They allow the creation of efficient mobile wallets while also allowing blockchains to communicate and interoperate like APIs.
A blockchain that supports any smart contract like Ethereum can be written to validate a NIPoPoW to find out if anything happened on a different blockchain and respond to it. But, the proofs about the blockchain can only be developed if the blockchain supports NIPoPoWs in its blocks.
This support can be included without a need for either a soft or hard fork and without approvals from the miner using velvet forks. A few cryptocurrencies have default NIPoPoWs support added since their genesis.
An observation as simple as some blocks achieving a better mining target than other is what the proofs of PoW are based on. The idea behind this is that there is no necessity to present the entire set of block headers to the network. Superblocks are rare and randomly occur and it can be simply illustrated as when a block hash needs to be started with 10 zeroes, in turn, starts with 15.
A series of these can form a superchain and if the superblocks are presented in the form of a proof, they demand pointers to be attached. This is called interlinking. A detailed installation and interlinking process can be found on their technical papers.
Aaron McDonald, Founder at skootapp tweeted:
“Interesting @centralityai and @plugblockchain are experimenting with a similar concept at the moment.”
Jordan Mack, a speculator says:
“When I first read the whitepaper I’m sure it took me over an hour just to decipher the basic concept. This website explains it in 3 minutes. Nicely done @dionyziz.”
A market enthusiast, Aadi commented:
“so that means ETH PLASMA model is impossible on PoW Consensus??? Thats why they wanna move to PoS. Makes sense.”
