Blockchain Trilemma - coined by Vitalik Buterin himself, is a condition in which the blockchain undergoes a compromising stage. It is truly believed that a fully decentralized network can never be scalable and secured at the same time.

Fuzz testing, or fuzzing, is a technique used to improve the security of software, including smart contracts in Solidity. It involves supplying random or unexpected data as inputs to a system in an attempt to break it and uncover vulnerabilities that manual testing might miss. Fuzzers generate a set of inputs for testing scenarios that may have been missed during unit testing, helping to identify bugs and potential security issues.

Dafi’s “dbridge” enables users to bring their ERC-20 $DAFI tokens across from the Ethereum network to Binance Smart Chain, and vice versa, with aims of making $DAFI available on multiple high-speed and low-cost networks.

Unipilot is an automated liquidity manager designed to maximize ”in-range” intervals for capital through an optimized rebalancing mechanism of liquidity pools.
