Quant (QNT) vs Gram (prev. Toncoin) (GRAM)

Quant Network is a service provider for developers, whose overall ambition is to build interoperability between blockchains and distributed ledgers of various ecosystems. Quant's technology, called Overledger, sits on top of existing blockchains and enables the development of multi-chain decentralized applications, meaning those that rely on multiple networks simultaneously.

The Open Network (TON) is an open-source ecosystem based on the TON blockchain. This network is the backbone of a complex, multi-layered architecture, composed of several "workchains," which are themselves divided into several "shardchains," allowing for a high level of performance. Initially built by the Telegram messaging team, the Open Network project is now independent and its development relies on its community of developers.
