if you read up on the Laser whitepaper it explains more in depth.
Laser operates on top of the blockchain as a layer and interoperates...
Laser will offer two other key features in its initial version:
The first feature is the use of an overlay protocol that provides “pseudo confirmation” of transactions, enabling any two cryptocurrencies to be transacted in a matter of seconds. This is a significant improvement over the processing times of other blockchains, which can take minutes, or even hours to be finalized.
The second feature is the optional “joining” service to make transactions anonymous in any cryptocurrency. This is accomplished by bundling multiple transactions together – where coins are “shuffled” and predetermined amounts are disbursed to predetermined recipients. This will obfuscate the ownership history of a given unit of a cryptocurrency, preventing it from being tracked through the blockchain.
On a broader scale, the full nodes that will comprise the Laser blockchain will be incentivized through transaction fees which full nodes on other blockchains do not generally benefit from. This will result in the improvement of the performance of the underlying blockchain – as without incentivization, many blockchains suffer from not having enough full nodes – and thus, not enough computing power. More importantly, these nodes will be required to provide collateral in order to operate – which disincentivizes dishonest behavior from rogue operators, giving integrity to the blockchain’s backbone.
thunderchain runs parrallel
Based on Xunlei’s proprietary homogeneous multichain framework, ThunderChain is designed to realize confirmation and interaction among homogeneous chains and enable multiple transactions to be executed on different chains in parallel. An optimized practical byzantine fault tolerance (PBFT) is adopted by ThunderChain as its consensus model which results in low latency and makes it possible to generate one block per second. PBFT, as a consistency algorithm, is also able to avoid soft fork. ThunderChain supports smart contracts written in solidity language and is compatible with Ethereum Virtual Machine (EVM), making it easy to migrate applications from other blockchain platforms.....
