Some blockchains instead use Proof of Stake, where nodes must have a certain quantity of tokens pledged in order to participate in voting. In a network like Bitcoin, it is very cost-prohibitive to try to acquire enough computing power to carry out a 51% attack as it is protected by Proof of Work. Mana is IOTA’s answer to Sybil attacks, wherein a malicious actor could try to gain control of the network by having 51% of the hash power. Research will be done on the Nectar network to ascertain the behavior of the network with more community nodes, and to refine how the reputation system, called Mana, will work “in the wild.” Mana – the answer to Sybil attacks It will be trading test tokens rather than real IOTA tokens so that flaws can be worked out before implementing Coordicide on the Mainnet. There is a huge incentive to attack permissionless networks, and the constant attack exposes any flaws quickly.Ĭhrysalis will have the protection of the Coordinator, but Nectar will be fully decentralized. Fundamentally, a network like Bitcoin, Ethereum, or IOTA is more secure than a permissioned network because it is battle-tested every day. Daily exposure to attacks is what hardens a permissionless network, Schiener explained. Nectar will expose the Coordinator-free network to attacks! Bounties will be offered to anyone who can exploit weaknesses within the Nectar network. We have published dozens of papers on Coordicide, and have already done the first practical implementation in the GoShimmer network, and they have already proven most of the components of Coordicide, including mana which is working very well. Schiener emphatically replied, “Nothing will prevent Coordicide.” He explained that the path to Coordicide was backed by very sound theory and research. One community member asked today whether any feedback from Nectar could possibly delay, or even cancel Coordicide on the Mainnet.
Hence, within weeks of launching Chrysalis, a Coordinator-free test network – dubbed Nectar -will be coming online. Killing the Coordinator, known as Coordicide, is thus critical for IOTA. Some will argue that this progress may not be as big a deal, especially since IOTA will still have a Coordinator – a node that issues transaction milestones as part of the confirmation process and is a potential single point of failure.
Schiener encouraged people to be building applications on IOTA since with Chrysalis, the core protocol will be production-ready for any business applications. It represents “ the best version of IOTA” with reusable addresses, UTXO, programmable transactions, and readiness for several key application layers including streams, identity, access, and smart contracts – all to be added over the coming weeks and months. This is not simply a new protocol, explained Dominik Schiener on Monday’s AMA. For users whose tokens are on exchanges, the exchange will handle the migration.
On Monday, the IOTA Foundation reassured the community that the weather looks great, and they are “ALL SYSTEMS GO.” Users can migrate tokens anytime this year, and so far, about $500 million in IOTA tokens have been transferred. That is about where IOTA is in relation to the launch of their new network, Chrysalis. NASA’s Space Shuttle launch countdown used to begin 40 hours before liftoff.
