    ETHBerlin will only use dApps for the event: messaging, livestreaming, audience voting, ticketing, accomodation and more.

    Posted: 07 Aug 2018 03:56 AM PDT

    Hacker applications are still up, you are invited to build the next big dApp! We believe that as we have now usable decentralized applications, we need to practice what we preach and deprecate the centralized old apps. Are you with us?

    Decenter introducing Etherships – A proof of concept 1v1 game based on our state channels framework

    Posted: 07 Aug 2018 10:16 AM PDT

    Hey guys,

    Just wanted to share some stuff that our team has been working on. We are building a state channels framework for 1v1 games that allows developers to keep the impact on the blockchain at an absolute minimum.

    Etherships is a PoC that uses all of our solutions so far, running at the moment on the Kovan testnet. You can try the game now at etherships.co or read the blog post for all the details.

    Edit: If you need some Kovan ETH, we have a faucet running at https://faucet.selenean.com/

    All feedback on the game and the ideas we presented is welcome and we'd love to hear your thoughts!

    We are building a secure mobile wallet system called AirGap

    Posted: 07 Aug 2018 04:40 AM PDT

    AirGap.it is a wallet solution, allowing the secure storage of secrets on a mobile phone with an approach of two mobile apps. Depending on the security needed these apps can be installed on separate devices or on the same device.

    To get the highest security, the AirGap Vault application is installed on a dedicated or old smartphone, which will never be connected to any network again. With the enhanced entropy concept that adds video, audio, accelerator and touch data to the entropy seed alongside the device's pre-shipped secure random generator it is possible to generate a cryptographically secure seed used for the secret generation on that very same device. This secret never leaves the device it was generated on. The private key is saved in the secure enclave of the mobile device and needs multi-step biometric authentication every time it is accessed to perform cryptographic primitives.

    AirGap Wallet on the other hand will be installed on a user's everyday phone. With this app, users can manage their portfolio of wallets and their valuations. AirGap Wallet deals only with publicly available information as opposed to AirGap Vault, which handles the private key.

    How does a transaction work? Detailed step by step guide.

    1. Users can create a new transaction with an address, amount and a fee in AirGap Wallet.
    2. A QR code with this transaction is generated.
    3. This QR code is scanned with AirGap Vault, ensuring one-way communication only with QR codes.
    4. To sign the transaction the secure enclave is accessed with biometric authentication.
    5. The signed transaction is displayed in a QR code.
    6. The QR code is scanned by AirGap Wallet and broadcasted to the blockchain.

    What if I want to manage smaller amounts?

    AirGap Vault and AirGap Wallet can also be installed on the same device. In this case, the communication between the two apps works with app switching through an URL scheme. This allows the two apps to be entirely encapsulated, which is crucial: For example, AirGap Vault does not have any network permissions and thus is unable to send information out over the network, guaranteed by the operating systems sandboxing.

    Which coins and token do you support?

    Currently we support the Aeternity (AE) ERC20 Token, Ethereum and Bitcoin. We plan to extend this list in the future. These are all managed by the same private key/mnemonic secret.

    We would be more than happy to get your feedback, comments and suggestions. You can also find more information on AirGap.it or on our Telegram channel.

    Test our first version of AirGap Vault Android and AirGap Wallet Android. The iOS versions are currently in review, reach out to test it over Testflight.

    How many people work for Ethereum Foundation?

    Posted: 07 Aug 2018 05:13 PM PDT

    The Ethereum Foundation has listed only three people on its website:

    VITALIK BUTERIN, PATRICK STORCHENEGGER, and JEFFREY WILCKE

    I imagine it must have more than these 3 people. I am curious about how many people actually work for EF.

    Why we need a 8x Token to enable decentralised recurring payments.

    Posted: 07 Aug 2018 06:52 PM PDT

    https://medium.com/8xprotocol/why-does-8x-need-a-token-6bd72ce9cd31

    TLDR — The 8x Token is used to incentivise a fair economy for the 8x Repeaters (service node operators who process the subscription transactions), by fair economy I do not mean that they are rewarded in 8x Tokens but that the 8x Token is used to solve issues such as the claiming problem, to prevent service nodes acting in a malicious way and also to facilitate some common economics principles.

    Trustless inter-chain transactions: any flaws in the idea?

    Posted: 07 Aug 2018 06:51 PM PDT

    Originally posted on Stack Exchange (https://ethereum.stackexchange.com/questions/56066/trustless-inter-chain-transaction-with-bitcoin-are-there-any-flaws):

    Let's say that Alice wants to send Bob 1 BTC, and in return Bob will send Alice 1 ETH.

    Alice's Bitcoin address is BTC_A, and Alice's Ethereum address is ETH_A. Likewise, Bob owns addresses BTC_B and ETH_B.

    BTC_B is a "fresh" address, with no transaction history whatsoever.

    Alice creates a single transaction to ETH_A containing slightly over the amount that she will send to Bob and broadcasts it. The transaction hash of this will be called tx1.

    Bob waits for that transaction to be confirmed and then creates a smart contract with the following (immutable) parameters:

    inputaddr, set to BTC_A

    inputtx, set to the tx1_txhash from above

    outputaddr, set to BTC_B

    minfee, set to a "reasonable" Bitcoin fee/byte, based on current network conditions

    waittime, set to the number of seconds after which a transaction with minfee will be confirmed on the BTC blockchain, plus a significant margin for safety

    val is set to an amount representing 1 BTC, or however much Alice is sending to Bob

    Bob also deposits 1 ETH into the smart contract, and is not allowed to withdraw it

    Alice submits a transaction, tx2, to the Bitcoin blockchain with the following properties:

    • inputtx is its only input
    • outputaddr is its only output address
    • fee > minfee
    • signed by BTC_A

    She also submits this whole transaction to the smart contract, which verifies these four properties. If they are all met, note the time as txtime.

    Bob will continuously monitor the Bitcoin blockchain, and if Alice tries to double spend the input transaction, he will submit the double spend transaction to the smart contract. The smart contract will verify that this transaction is legitimate, and if it isn't identical to the first transaction that Alice submitted earlier, will refund the ETH back to ETH_B.

    Bob will also be able to withdraw the locked ETH if Alice doesn't submit the BTC transaction to the contract in a reasonable amount of time.

    If waittime has passed since txtime and Bob hasn't submitted proof of a double spend, Alice can withdraw the locked ETH to ETH_A at her leisure.

    This seems like the kind of thing that someone would have already come up with, but I couldn't find any other trustless examples of a BTC-ETH exchange. Is there a fundamental flaw in this system?
