Milestone: A milestone is a special transaction issued by a special node called a coordinator. The coordinator is operated by the Iota Foundation and its main purpose is to protect the network until it is strong enough to endure massive attacks from people with GPUs. Milestone set the overall direction of entangled growth and made some sort of checkpoint. Transactions (in) directly estimated by milestones are considered confirmed. In other words, in the current form of IOTA, there is no resistance to review as the path of the tree is instructed intensively via the coordinator node being executed by IOTA Foundation. Therefore, IOTA is not as fragmented as Apache Kafka cluster or Ripple and its unique node list. (Edit: This also opened the IOTA to make a double attack from the coordinator himself, I submitted a question, the question is over and there is no response.
2017 is a wonderful event for the IOTA project. Milestone was reached, violation of record, and many newcomers joined the team. The project independent of our community using IOTA exploded. This growth indicator is the growth of our subsidiary over the past few months. We invested a lot of money to establish the IOTA Foundation as a German non-profit foundation in 2017. It became the first German non-profit organization focused on distributed ledger technology but it is itself an important milestone, the foundation was established correctly in 2018, and the impact as a non-profit organization in Germany is It will be very obvious. Actual viewpoint
Milestone 4 is a very important milestone and it is very important to make the RChain test network equivalent to Ether's POS update Serenity. Someone has talked about milestones for over 14 years (over 5 years). The implementation risk of this project is very high, as their primary network release time is very long and the details of the roadmap are very clear. As obvious from that document, RChain is trying to compete with their main encryption chain Ethereum and Bitcoin. They are most similar to Ethereum as they have smart contracts and scaling methods. However, there are other chains that inevitably compete with them. I thought about a chain like NEO, Icon and Dash and Ripple. In this sense, it is operated in a very crowded competitive space, each competitive space is opening its own niche market.
