EigenLayer seeks to solve the problem of fragmented blockchain security by pooling Ethereum’s security for other applications to utilize with their restaking technology. Cosmos has focused on a slightly different solution to help increase the security of its appchains with its Replicated Security model. Neutron is the first project to launch using this technology, with many others coming soon. A notable Cosmos project, Osmosis, has proposed its own version of shared security called Mesh Security, focusing on stakers rather than validators. On Bitcoin, Babylon has been working on a solution to leverage the security of the Bitcoin blockchain to increase the security of Cosmos appchains and eventually other proof-of-stake (“PoS”) blockchains. Stacks, with their novel proof-of-transfer (“PoX”) consensus mechanism, has also worked out a solution to using Bitcoin to secure its transactions. Developments in the upcoming Stacks Nakamoto Release will further solidify this technology.
