Communication convention (IBC) in mid 2021 moved regard for executing shared security, which started testing in the final quarter of 2021
This permits more up to date, more modest blockchains to “lease” security from more settled organizations
Confirmation of-stake (PoS) networks are gotten by validators who stake tokens on the organization to approve exchanges and produce blocks. The general security of a PoS organization, then, at that point, will generally be in relation to the all out market cap of the token, in light of the fact that the more tokens being marked, the higher the expense of assaulting the organization.

The market cap of a PoS network is fairly comparable to the hash rate in a proof-of-work (PoW) organization. The higher the hash rate, the more trouble an assailant would have in attempting to assume control over the organization by controlling most of its mining power. Essentially, the higher the market cap of tokens on a proof-of-stake organization, the more assets it would take for an aggressor to control an adequate number of tokens for an effective assault.

Ways of assaulting a PoS organization
While a 51% assault requires controlling 51% of the hash pace of a proof-of-work organization, verification of-stake organizations can be assaulted regardless of whether an agitator controls under a greater part of the organization’s assets.

“Assuming that you control 33% of an organization, you can do restriction assaults, which means you can keep specific exchanges from being executed… on the off chance that I control 66% of the organization, I can handle administration and pass a proposition for a malignant overhaul or channel the local area pool with a spend proposition. There are different ways that can be utilized for accursed means,” says Billy Rennekamp, Cosmos Hub Lead at the Interchain Foundation and individual from the Board of Management.

This makes shared security considerably more significant. Some portion of what makes PoS networks hard to assault is the expense of obtaining that multitude of tokens. To get 33% of the Cosmos’ ATOM token would cost about $2.3 billion, not to mention the value sway it would have if abruptly somebody fired purchasing up that numerous tokens.

“Shared security is the capacity to utilize one marking token across various organizations to get those organizations,” says Rennekamp.
