Ethereum co-founder Vitalik Buterin published a plan on Monday for the first hard fork of the new Ethereum 2.0 Beacon Chain, tentatively named HF1.

The difficult fork would allow the developers to introduce several central upgrades to the recently launched Beacon Chain, which would also serve as a useful test for deeper changes in the future.

The biggest practical alter is the support for low-cal clients — nodes that would have minimal resources requirements and could run on mobile devices. This would let for "trust-minimized wallets" that are able to verify the blockchain on their own instead of relying on external service providers.

Light client back up is introduced through special-purpose "sync committees," groups of validators that are randomly assigned to create special signatures that make information technology easier to determine the correct version of the chain.

Other improvements include fixes to fork choice rules, where developers identified several instances of the protocol beingness potentially vulnerable to reorganization attacks. The issues are subtle and crave precise timing, just they could have allowed malicious actors to exploit the network while controlling a modest portion of validators. These weaknesses were known before launch simply were discovered besides late to be fixed in time, Buterin wrote.

In terms of applied changes, the hard fork aims to overhaul how the slashing and inactivity leakage mechanics work. Currently, stakers on Eth2 may lose a portion of their uppercase either due to being inactive or by attempting to support a minority fork of the chain, which is punished with slashing.

Inactivity leakage was sometimes considered a deterrent to dwelling house staking, due to being penalized for force majeure issues similar a patchy cyberspace connection or blackouts. While the system was prepare to be very lenient, the team is now farther tweaking the mechanism to brand life simpler for stakers with unstable connections. The leak is set to become quadratic, meaning that there volition be a significant difference between intermittent and continuous inactivity. For a crude example of the magnitude, a staker who experienced 10 outages for a vi minutes each, totaling ane hr, would lose 10 times less than some other staker who simply disconnected their machine for one continuous 60 minutes.

Inactivity leaks will also cease gradually instead of immediately, which ensures that offline nodes will keep losing value until the network is well to a higher place the necessary threshold for security.

While some of the changes brand the organisation more lenient for honest mistakes, the team is irresolute some parameters to introduce harsher monetary penalties for bad behavior. This is aimed to "weaken the training wheels" of the system.

Information technology is unclear when the hard fork will be performed, with evolution and review notwithstanding required for some of the details of the proposal. In the meantime, the Ethereum developers are trying to come up with a naming convention for HF1 and future hard forks. Proposed themes so far include names of stars, planetary systems, World of Warcraft zones and months of the twelvemonth, among others.
