Znodes masternodes have launched on testnet now, integrating the functionality of DASH.
When znodes launch on mainnet, a an estimated 50% of XZC will be locked up in masternode wallets.
MTP (merkel tree proofs) are on the roadmap.
This is good news and the price reflects this.
More info is here including the timing for the start of the znode payouts:
From now on holders of Zcoin are incentivised to hold their Zcoin as the collateral for their znode masternodes to generate weekly interest payments.
There will be some profit taking on the news, but long term this means that less Zcoin will be on the market.
Further upside possible long term but profit taking on the news of the znode / masternode launch is also possible.
