It&#8217;s still a very secure system,\u201d he added.<\/p>\n<p><strong><em>Related: <\/em><\/strong><strong><em>Buterin and Armstrong reflect on proof-of-stake shift as Ethereum Merge nears<\/em><\/strong><\/p>\n<p>The security expert added that \u201cEthereum is working on fixing [the consecutive block issue]. <\/p>\n<p>It is a hard problem to solve, but if that gets done, then proof-of-stake security will [further] increase [as] they\u2019ll have protection against those attack vectors.\u201d<\/p>\n<p>Ethereum validators are subject to slashing in PoS, as the consensus rules were designed to economically incentivize validators to correctly validate incoming transactions and any conduct to the contrary would see their ETH stake slashed. <\/p>\n<p>The Ethereum Merge is finally set to take place on Sept. 15 at about 2:30am UTC, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.blocknative.com\/ethereum-merge-countdown\">according<\/a> to Blocknative\u2019s Ethereum Merge Countdown.
