“# Grin network hit with 51% attack while GRIN token remains resilient <\/strong>”
\n<\/p>\n

Grin, a privacy-focused cryptocurrency built on the Mimblewimble protocol, has just suffered a 51% attack on its blockchain.<\/p>\n

According to a Nov. 7 tweet from crypto mining group 2Miners, an unknown group accumulated<\/a> 57.4% of the total hash power of the Grin (GRIN) network on Saturday evening. 2Miners only had control of 19.1% of GRIN\u2019s hash power, while sparkpool miners came in third at 18.9%. <\/p>\n

Grin Network Is Under the 51% Attack!<\/p>\n

Payouts are stopped. Please mine at your own risk only because the new blocks could be rejected.@grincouncil<\/a> @grin_hub<\/a> @Hotbit_news<\/a> @Poloniex<\/a> @kucoincom<\/a> @gateio_info<\/a> @CoinBene<\/a> pic.twitter.com\/6seDSRe8Qw<\/a><\/p>\n

Data from GrinScan shows<\/a> the attackers were able to reorganize at least one forked block, at 23:17 UTC on Nov. 7. The unknown mining group has also increased<\/a> its control since Saturday, commanding 58.1% of GRIN\u2019s hash rate at the time of publication. 2Miners\u2019 has risen to 24.6%, while sparkpool miners\u2019 has dropped to 11.3%. <\/p>\n

When a group of miners controls more than half of a network\u2019s mining power, it can affect the organization of blocks, potentially causing volatility in the token price and disrupting confidence in the blockchain. However, a mining group having control of 51% or more of a network\u2019s hash rate does not necessarily mean it has ill intentions \u2014 sparkpool has had up to 60% of the network\u2019s hash power before and reportedly did not interrupt the production of new GRIN blocks. <\/p>\n

The GRIN token remains relatively unchanged on the news<\/a>, falling just 1.3% over a 24 hour period.\u00a0<\/p>\n

The Ethereum Classic (ETC) blockchain suffered at least three 51% attacks in August, with attackers causing the reorganization of thousands of blocks. Unlike the ETC blockchain \u2014 which would cost attackers more than $7,000\/hr to control more than half of the blockchain\u2019s hash power \u2014 sustaining a 51% on the GRIN network only costs<\/a> $75 at the time of publication, according to online resource Crypto51. <\/p>\n
