    Now deploy your smart contracts with MetaMask using Truffle Teams!

    Hey everyone,

    Big holiday release here. We just deployed a new feature in Truffle Teams some are already calling game changing. Now you can deploy your smart contracts using Metamask, Ledger and Trezor, with Truffle Teams

    • Easily deploy to public Ethereum networks using MetaMask (Mainnet, Ropsten, Görli, Rinkeby, and Kovan are supported)
    • No more importing private keys - use MetaMask to deploy like you would with any other dapp
    • Control your production deployments by approving each transaction every step of the way
    • Deploy with Ledger or Trezor hardware wallets to keep your deployments secure

    Truffle Teams uses your Truffle migration scripts under the hood, which means there's nothing new you need to change. And because you can deploy through Metamask, you get a better -- and safer -- production deployment process.

    Read more about Metamask deployments with Truffle Teams.

    Nethermind with a Proof of Concept of Beam Sync

    Nethermind with a Proof of Concept of Beam Sync

    Just finished a PoC work of Beam Sync between Nethermind Goerli Full Archive and Nethermind Beam Sync Client.

    It works with existing protocol but probably requires a week or two to polish and to be production ready. Not prioritized for now but maybe we will be able to pick it up in January.

    Artist here that produces artwork on SuperRare just wants to thank the entire Ethereum community.

    Posted: 19 Dec 2019 05:02 PM PST

    I go under the name of Robness Cyberpop and I myself produce various types of artwork that grabs elements of Cyberpunk/Vaporwave/Pop Art elements. Currently because of the advancements of smart contracts I am collaborating with someone I've never even met in person on art and we both are doing well in sales while the profits are divvied up immediately(a promise that was made and kept by Ethereum developers years back). Not sure if the Ethereum community at large is aware of SuperRare.co or KnownOrigin.io and how they are breaking record sales by the week but just wanted to drop in spread the good news. These advancements are helping tons of artists around the globe make an actual living off of their work and it's just really great to see. Although those darn Cryptokitties like to take a lot of the limelight, there are artists right now developing styles that are truly revolutionary. Thanks everyone!

    Why will the beacon chain move beyond a testnet early next year?

    Posted: 19 Dec 2019 01:53 PM PST

    As far as I know there will be no utility from the beacon chain for a long time after it begins. ETH1 could take a couple years to use it for finality and until phase 1 the beacon chain will be useless, but it'll still be growing history, adding to inflation and increasing future client complexity as they'll have to handle both sides of early hardforks. What's the benefit to beginning the real thing so long before phase 1 over keeping a testnet running and having the genesis later? Development of 1.x could progress just as well relying on the testnet and the real thing can launch long enough before 1.x is ready to use it to get the follow distance down.

    Do you want to receive a fixed interest rate on your stable coins?

    Posted: 19 Dec 2019 10:32 AM PST

    Do you want to receive a fixed interest rate on your stable coins?

    With interest rate swaps (IRS) it is easy! You need to choose a maturity, accept fixed interest rate and enjoy your fixed-rate deposit.

    How it works and how secure it is?

    You don't need to trust all your money to interest rate swaps (IRS), you just trust a small fraction of your deposit, which is enough to compensate for small interest rate fluctuation. The rest of the money you can still place to a floating rate deposit (like Compound.finance, Fulcrum and other). IRS works in a way that it will give you compensation if the actual floating rate is low during your deposit time. But also you will pay to IRS an excess that you may get from your floating rate deposit over the agreed fixed rate.

    So it is like an insurance that you get for on top of your floating rate deposit at Compound project. It doesn't cost anything due to the fact that you share the risk and will pay away everything you get above a specified fixed rate.

    Let's explain how it works in the following example:

    You have a deposit at Compound that you intend to hold for 12 months. You expect that it will bring you from 5 to 12% over the year, but you don't like uncertainty. You can get an interest rate swap with a 10% fixed rate and be sure that you will get exactly 10% in one year, whatever happens with the compound floating rate at the same time.

    Indeed if the effective rate on Compound during the year will be 7% you will receive the remaining 3% from the interest rate swap. And if the effective rate will be 12% you will pay 2% to interest rate swap.

    https://preview.redd.it/v7hvgftsvm541.jpg?width=2880&format=pjpg&auto=webp&s=af4ec558831adae382d0db635c569def7633b928

    Good news that it is enough to lock in the swap, not more than 10% of your deposit amount because it will be enough to pay (or get paid) the difference between actual rate after one year and the fixed-rate (unless compound average rate goes over 18% during one year, which is not realistic).

    Even more:

    Interest rate swaps allow you to hedge your deposits or loans, take a long or short position on lending/borrowing rates, make the financial system more efficient and much more.

    For example, if you fix your borrowing rate in the same style, you can stop worrying when the borrowing rate is getting volatile. So we will see fewer money outflows from the Compound ecosystem when the borrowing rate temporarily going high.

    But it is a story for a proper article, we will keep you posted.

    We built swap.rate on top of the Орium Protocol. It is in main-net and ready for use.

    Node-based Smart Contract Editing

    Posted: 19 Dec 2019 06:01 PM PST

    Does anyone know of a "node-based" visual smart-contract builder? Something that uses established cryptographic primitives and libraries that would allow a user to build and deploy without knowing how to code? Something like this. https://www.youtube.com/watch?v=qTCZFkICOlk Thanks!

    Find bugs!!!

    Posted: 19 Dec 2019 04:18 PM PST

    Hello, this is Jeayoung Han, the CEO at Mycoldwallet.

    I'm excited to announce the completion of our project Mycoldwallet.

    Prior to the project launch, to verify its security and guarantee its safety, we are planning to hold a Hacking Contest to the public.

    Everybody, please come and hack the blockchain account if you can!!

    📷

    Purpose of the event: To find any possible malfunctions or errors that can cause inconvenience or security problems. Anyone who can control the protection account without the signature of either the user or management system is the winner of the contest.

    Dates of the event

    1st round: 10~15 of Dec.

    2nd round: 16~22 of Dec.

    3rd round: 23~29 of Dec.

    Prize for winners

    1. Critical bug detector: $1,000 and 20,000 MCW Tokens
    2. Normal bug detector: $200 and 5,000 MCW Tokens
    3. The leftover prize from each round will be carried forward to the next round.

    ** Critical bug: A situation that can make the protection account locked or have the assets in the account transferred to another place without the user signature.

    ** Normal bug: A situation that cannot control the protection account but that can cause small operational glitches.

    ** Any participants who find a problem or error in the program can contact [contactus@mcws.io](mailto:contactus@mcws.io) for the reward.

    ** The first verified detection is only valid for the reward.

    Detailed information

    a.Target protection account(Rinkeby Testnet)

    https://rinkeby.etherscan.io/address/0x8c67f07dcdcf8acb307f3b0500a6333c0e60002d

    b. ABI link of the protection account https://mycoldwallet.io/download/ProtectedAddress.zip

    ** The participants can use all the command words on the ABI file attached here.

    ** Explanation of Mycoldwallet: We are a cryptocurrency wallet service program that provides a Protection Account which is programmed with the Smart-contract. At the time of the account creation, the system registers two signatures in the account. One is a user's signature and the other is a management signature. The activation of the keys is controlled by a waiting period that the user selects on the account setup. During the waiting period, only the user's signature can control the account but when it expires the management signature can control the account. This waiting period is automatically renewed when there is a withdrawal in the account.

    I invite any hacker who is up to the challenge to help us improve our service.
