Topic: [ANN] Zcoin (XZC) - Implementing ZKP privacy without trusted setup - page 39. (Read 662757 times)

Crypto Lark recently interviewed Reuben on where he thinks privacy fits with governments, PoW vs PoS, blockchain adoption and regulation in SE Asia and how we shouldn't be trusting anyone with our private data be it large organizations or governments.

This was one of Reuben's favorite interviews so we highly recommend you check it out!

A couple of weeks ago Eugene from Rock the Block Live interviewed Reuben on a wide range of topics in Singapore.

Catch Reuben, Zcoin's COO in an AMA on Binance's Telegram on 6th March 9:30 AM UTC. There will be a 100 XZC up for grabs and 3x Zcoin swag packages to giveaway!

An interesting service called @phitbone has just popped up allowing people to rent a physical phone number that can send and receive SMSes using Zcoin $XZC exclusively. Remember to use TOR to access the site together with Zerocoin spends!

Catch Zcoin at the MIT Bitcoin Expo 2019! On the 9th March, our Zcoin Ambassador to Boston, Matt Koskinen will be doing a talk on “Lelantus: Improving on Zerocoin”

Check out the details at: www.mitbitcoinexpo.org

Check out this detailed guide on HashRaptor's experience of mining using MTP on Zcoin $XZC!

Lelantus

    cryptographic building blocks have been built
        Sigma for double blinded commitments with batching
        Bulletproofs for double-blinded commitmtsn with batching
        LelantusProof and LelantusVeirfy functions which generate and verify transaction proofs with multiple input and output coins (combination of Sigma, bulletproofs and balance proofs).
    Code clean up is happening and to be verified before implementation

Sigma

    Implementing ECDSA signature scheme similar to what we have for Zerocoin to address the “Burning Zerocoins for Fun and Profit” vulnerability.
    Testnet is coming online soon. Slight delays due to fee handling.
    Working on Sigma partial spend feature (where output is an arbitrary amount and the change is reminted) and should be able to push code soon.

MTP

    New ccminer released with updated bos jansson.
    Sgminer feedback is stable
    CPU miner: working on some issues where cpuminer stops mining intermittently.
    Added on Nicehash. To monitor available hashrate to evaluate 51% attack risk.
    Hashrate has increased significantly. Pools do not suspect FPGA/ASIC as it looks to be more of a combined effect of MTP being listed as the most profitable on Whattomine and Nicehash
    Python module for MTP being coded to evaluate whether MTP decentralized P2Pool is possible.

Core Upgrade

    Upgrade to 0.14 is more or less complete but 0.17 is delayed
    This is due to masternode code from Dash is designed for 0.13/0.14.
    Using core upgrade opportunity to update masternode code then upgrade to 0.17
    Once masternode code is integrated upgrade from 0.14 to 0.17 is simpler.

Electrum MTP

    Detected a bug where Electrumx doesn’t react too well in chain forks. Fixing

Themis: Smart Contract Capability

    Discussion on EVM vs WASM
    Smart contract second layer which utilize Zcoin opcodes.
    Discussion on whether EVM should only be validated by Znodes
    Code is being updated to core 0.17 as well.

GUI

    Some small bugs in relating to spending multiple Zerocoins in one tx due to the way weightage is calculated.
    To fix completely, will need a hard fork for it to be clean. To do this with Sigma.
    Resolving then proceeding with public beta release.

Magnum wallet as well as Trust wallet will mutually contribute to spread the popularity of Zcoin out to their users.
Months later, those two partnerships and two crypto wallet platforms will show their general effects (positively, I believe).
I thought that the Zcoin team made very highly potential partnerships with Magnum and Trust wallets.
Congratulations to all three sides, Zcoin, Magnum, and Trust.

Happy to announce another Zcoin wallet integration! Magnum Wallet is a light web wallet that makes it easy to receive and send Zcoin!

We are happy to announce Zcoin's $XZC support in one of the best wallets out there Trust Wallet along with its deep integration with Binance. We look forward to private tx support in the not too distant future!

Zcoin's Biggest Challenges in this Bear Market https://www.youtube.com/watch?v=5qXVDiG3lPw&feature=youtu.be

Reuben talks frankly on the challenges Zcoin faces in this bear market and how development continues unabated despite the conditions.

Nicehash is bad for profit. Let them go to hell and Nicehash and his owner.  Already Zcash is not profitable for mining. I do not know what is the brains of the miners which are renting Nicehash.

Not going to happen as there are too many alternatives and nobody will trust them again like was the case with Poloniex years ago. When they were hacked they resumed operations and paid back everyone.
