Meter is a high performance infrastructure that allows smart contracts to scale and travel seamlessly through heterogeneous blockchain networks. Meter is a Layer 1 and Layer 2 blockchain protocol. The Meter system consists of two tokens: MTRG, the governance token (eMTRG is the ERC20 version), and MTR, the low-volatility currency token. Financial assets should flow freely among blockchains. Meter’s HotStuff-based consensus allows 1000s of validator nodes, making Meter the most decentralized Layer 2 for Ethereum. Meter processes thousands of transactions per second and transactions are confirmed almost instantly. Meter Passport allows assets and smart contracts travel and communicate across heterogeneous blockchains for the best price, liquidity and yield. Meter is an Ethereum Compatible with unique enhancements. Unlike other Layer 2, DEXes build on Meter are front running/MEV resistant, fast and uncensorable.

TON is a fully decentralized layer-1 blockchain designed by Telegram to onboard billions of users. It boasts ultra-fast transactions, tiny fees, easy-to-use apps, and is environmentally friendly. TON is scalable and shareable. Its flexible architecture lets it grow and grow, with no loss of performance. It's used for transaction fees, securing the blockchain through staking, deciding how the network develops, and settling payments. TON has plenty of unique features that differentiate it from other layer-1 blockchains. The actor model is a mathematical model of concurrent computation and is at the heart of TON smart contracts. In it, each smart contract can receive one message, change its own state or send one or several messages per unit time. As a result, the entire blockchain, as well as a given contract, can scale up to host an unlimited amount of users and transactions. The TON Virtual Machine (TVM) is a deterministic, fully-featured stack-based virtual machine.
