Next week the ethereum classic (ETC) community is expecting to receive coins from a 'snapshot' fork called 'callisto' (CLO). The clone will be an exact copy of the ETC chain up until block 5,500,000 and ETC holders will receive a 1:1 ratio of CLO coins.
The First High Profile Hard Fork Is About to Get Forked
The funny thing about ethereum classic is that it was one of the first high profile blockchain splits and ethereum (ETH) holders received a 1:1 ratio of ETC after the hard fork at block 1,920,000. The fork was caused by members of the Ethereum community because they rejected the idea to 'bail out' the DAO, an ETH application that lost $150Mn that year. Some individuals firmly believe that ETC is the 'one true' Ethereum network. Callisto, however, is not quite like the ETC hard fork as it's a snapshot much like bitcoin gold, bitcoin diamond, and the other clones that appeared over the past year.
Callisto Developers Believe CLO Will Have Better Smart Contract Security
Essentially CLO coins will share the same history as the existing ETC chain but from block 5,500,000 and forward the network will be its own. The cloning is expected to happen next week sometime on or after March 2. The reason behind the snapshot is because CLO developers believe there are issues regarding ETC's smart contract design. According to the CLO white paper ETC is susceptible to smart contract hacks much like the DAO platform. The CLO developers plan to create a "Official Smart-contract Auditing Department of CLO & ETC," so one could assume the snapshot may be considered an extension of the ETC community.
"The main goal of callisto is to research and develop a reference implementation of self-sustaining, self-governed, self-funded blockchain ecosystem and development environment," explains the CLO white paper.
Callisto aims to establish a secure and contribution-friendly environment for further protocol development and improvements. It will rely on a built-in system of smart-contracts to achieve this goal.
