Bitcoin Cash (BCH) vs Gram (prev. Toncoin) (GRAM)

Bitcoin Cash is a Proof of Work (PoW) blockchain that was born on August 1, 2017, following a hard fork from Bitcoin due to a disagreement within the Bitcoin community. While the majority of the community chose to adopt the SegWit proposal, a dissenting faction decided to split the blockchain (hard fork) and implement their own improvement, namely an increase in block size from 1 MB to 8 MB, following the original vision of Satoshi Nakamoto.

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.
