Staking support for more coins to come
Furthermore, the exchange announced plans to add other Proof-of-Stake (PoS) coins later. The announcement explains that an easy way to access staking “allows more people to earn rewards for contributing to the network by promoting network security, reducing validation costs.”
“Staking is just one of the many attractive ways we are bringing new people into the digital asset marketplace. We consider this another step towards achieving our goal of financial inclusion for an ever-growing pool of people.”
The announcement follows the launch of a dedicated staking platform by Binance’s principal cryptocurrency trading platform at the end of September 2019. Staking is an activity possible on PoS-based blockchains that allows the network’s nodes to validate blocks by holding cryptocurrency as collateral.
While in the case of Bitcoin (BTC), a 51% attack requires a barrage of processing power, in the case of a PoS blockchain, a 51% attack requires the attacker to hold a great number of the coin that they are attacking. As Cointelegraph recently reported, Bitcoin Gold’s (BTG) blockchain suffered a 51% attack resulting in over $70,000 worth of BTG being double-spent.
The initiative, often referred to as staking-as-a-service, attracted some criticism from the cryptocurrency community. Dovey Wan — founding partner of blockchain-based investment company Primitive Ventures — has commented at the time of the announcement:
“That’s why RIP for all StakingaaS Exchanges gonna eat it, custodial wallets gonna eat it, even PoW pool gonna eat it, and then the remaining is a race to the bottom Bad business, just bad.”
