    Send private messages to Ethereum users [beta]

    Posted: 03 Mar 2018 11:25 AM PST

    A little while ago I had asked if an app allowing Ethereum users to PM each other would be useful (https://www.reddit.com/r/ethereum/comments/7w3tn5/would_a_simple_app_allowing_ethereum_users_to_pm/) and made the first version of it this Saturday:

    http://www.cryptospeech.com/im

    Anyone can send a message to any Ethereum address here and to read your messages for an account you'd visit the site connected to MetaMask under that account. Super simple. An ordinary database is used so it's free and instant rather than having a smart contract which would cost Ether for every message sent (though I could make that as well).

    As before not sure how useful this is but if I were to expand on it I'd also implement the following:

    • Let the user see their sent messages
    • Show the user a list of their contacts who have sent them messages, and who they have sent messages to - clicking on a contact would then open all sent/received messages like a normal messaging app
    • Update the messages for a user soon as one is received rather than the user having to manually refresh

    Any feedback appreciated. You can easily test it works by opening the site while connected to an Ethereum network with MetaMask, sending a message to the account you're connected with, and refreshing the page.

    Hey Reddit! I made a simple, open source website to archive text on the Ethereum blockchain. Introducing ETHTXT.io

    Posted: 03 Mar 2018 11:21 AM PST

    Hey all!

    ETHTXT is a simple site that allows you to easily archive text on the ethereum blockchain. There are no fees aside from the gas costs to execute the smart contract.

    Archiving text will give you a url like: https://ethtxt.io/mnYDR

    I spent the past few weekends building ethtxt as a fun project in order to learn more about web3 / solidity development. This is my first time to open source a project and I'd love to hear your thoughts / receive your stars on github 😉.

    You can check out the source code of the web app here

    and the solidity contract code verified on the blockchain here

    If you'd like to donate to my future dapp development, you can send eth to the following address, but please don't feel obligated! 0xBf99DBC5bd222900eC43f05D8faAe17eAfa6Ca1B

    I made this project for fun and will continue to develop more fun projects in the future.

    Thanks for checking it out!

    Probably dumb question about pos.

    Posted: 03 Mar 2018 05:48 PM PST

    In a pos dystem, exactly what is it that makes the real bloxkchain the real blockchain? Mean in a pow system, if one pool alters the block and mines it, it will get false transactions but as long as people trust the chain with the most work put in to it. Unless the miner has more than 50%, the real blockcain will be bigger because they will confirm more blocks. This is how I have understood it at least. But what is the work in a pos systwm, you can fork it as you want and choose how much money you have in stake. You can how many blockcains as you want with an an equil amount os stake. So what is it that I you to identify the real one?

    Again im not ab expert by anh means, just trying to understand it as much as I can.

    How Blockchain Will Transform Real Estate

    How often do you guys get random tokens?

    Posted: 03 Mar 2018 09:33 AM PST

    Hey so I seem to have some random tokens just show up at my address lately I was wondering if this is common to happen to anyone else at all? I did not participate in any airdrop or anything like that, I think the last thing I did before I received the tokens was use Bancor so maybe someone was looking at the tx's made to that contract?

    the tokens are called VIN(0xf3e014fe81267870624132ef3a646b8e83853a96) and BPTN(0x6c22b815904165f3599f0a4a092d458966bd8024). if anyone knows anything about them.

    Reducing Data Redundancy in a Block

    Posted: 03 Mar 2018 06:51 PM PST

    I was hoping to get some ideas about how to reduce data redundancy in the ethereum blockchain. The overall idea is to make the block size as small as possible. Can the attributes of a block be classified as

    • Mandatory

    • Optional but good for security

    • Optional but good for performance

    • Optional but good for scalability

    • Optional but good for future upgrades

    • Optional and unimportant

    What other categories do you think we could have?

    It would be great to see some constructive conversations.

    Also if you could spare a minute of your valuable time to fill out a survey about ETH prices here, it'd be really very helpful.

    Thanks, M

    Sent ERC20 token to ETH address. Have I messed up?

    Posted: 03 Mar 2018 05:31 AM PST

    I got some ERC20 token and for some reason decided to just send them to my ledger ETH address.

    Have i lost them or is there a way to get to them?
