EOS - Developer’s Log Stardate 20176.30

avatar

This week block.one’s blockchain c++ development team has picked up 4 new members and has been interviewing a few more. The new recruits have already begun making contributions to the code.

Removing Registered Message Schemas

With the move to WebAssembly (WASM) we have had to re-evaluate some of our earlier design decisions based on the assumption of using Wren. Because WASM is language independent, every application would have to provide different WASM for parsing the messages passed to the application. This means the ABI (application binary interface) is technically defined by the WASM parsing and not our prior builtin registered message types and formats.

Since the blockchain is unable to enforce the message schemas and every contract would have to independently parse and validate the incoming binary data, we opted to remove the blockchain defined message schemas. This gives more power to application developers.

Changing Account Name Structure

One of the bigger changes to the code this week was changing account names from 256 bit strings to 60 bit integers that convert to human-readable names via base32 encoding. This limits the account names to 12 lowercase letters and a few numbers. The average Twitter account is only 12 characters long.

This change was made primarily out of bandwidth, memory, and performance considerations. From an applications logic perspective an account name is simply a unique identifier and they are used everywhere. The old ABI would serialize these account names as length-prefixed strings and require a computationally intensive unpacking process.

By moving to a fixed-width integer representation for accounts we got performance, but the developer experience was less friendly. To resolve this we simply print the integers as base32 and this gives human-readable names.

Longer names can still be supported by registering them with a name service contract.

A typical transfer message is 75% smaller after this change, which makes a big difference when you are processing 10's of thousands of them per second.

Filtering Floating point from WASM

We updated the WASM processing to detect and reject code that uses floating point operations which can generate non-deterministic behavior.

Sandboxing WASM Runtime

We made significant progress toward injecting checkpoints into WASM to allow us to check the runtime and abort if too much time has passed. This is a critical component of running untrusted code.

New C++ Simplecoin (80,000 TPS)

In one of my prior updates I showed a proof-of-concept currency smart contract written in C and achieving 50K transactions per second. I mentioned that I thought we could clean up the syntax and today I am happy to show a new implementation of the simplecoin in C++ that gets compiled to WASM and then executed. Using a tight loop of generating and pushing transactions to the blockchain we achieved 80K TPS transferring funds from one account to another in a single thread.

Real world performance may be higher or lower based upon the evolving architecture, it is still too early to tell. All measurements were made on a 4Ghz Intel Core i7 in a 2014 iMac.

struct Transfer {
  uint64_t    from;
  uint64_t    to;
  uint64_t    amount;
  char        memo[];
};
 
static_assert( sizeof(Transfer) == 3*sizeof(uint64_t), "unexpected padding" );
 
struct Balance {  uint64_t    balance; };
 
void on_init() {
  static Balance initial = { 1000*1000 };
  static AccountName simplecoin;
  simplecoin = name_to_int64( "simplecoin" );
 
  store( simplecoin, initial ); 
}
 
void apply_simplecoin_transfer() {
   static Transfer message;
   static Balance from_balance;
   static Balance to_balance;
   to_balance.balance = 0;
 
   readMessage( message  );
   load( message.from, from_balance );
   load( message.to, to_balance );
 
   assert( from_balance.balance >= message.amount, "insufficient funds" );
   
   from_balance.balance -= message.amount;
   to_balance.balance   += message.amount;
   
   if( from_balance.balance )
      store( message.from, from_balance );
   else
      remove( message.from );
 
   store( message.to, to_balance );
}

Not only is the code cleaner and easier to read, the generated WASM code is much smaller too. Most of this time and space savings is made possible by changing the account name and ABI for this contract. In this case the ABI uses a zero-parse copy from the database to the c++ struct and all account names are fixed length.

You can experiment with this code on WasmFiddle with this shared link.

Conclusion

The EOS development team is growing and the technology is progressing with all signs pointing toward a very high-performance platform even running in a single thread. Stay tuned for more updates!

Tried the example. "Build" and then "run", I get:

line 3: Uncaught TypeError: wasmInstance.exports.main is not a function

is supposed to output something?

no, you have to save the WASM and run it on the blockchain.

Achieving 80K Transactions Per Second would be truly incredible, i guess EOS will be the fastest among all crypto-currencies. Congratulations and warm welcome to all the new EOS developers .

If they can pull it off, it will be the fastest without a doubt, c++ and "c" are machine level coding languages basically, the closer you get to machine level, faster the data transmission because gpu's are hardware so no need for conversion after a hash hack. I truly applaud them on trying.

Don't know man. With today's operating systems, you really never code at hardware / machine level anymore. Back in the DOS / Win 3.1 era you could make a C program talk directly with the parallel port.
When newer OS arrived, those same programs would crash as they no longer had permission to talk directly with the hardware, needing to go through the OS API instead. There is always some layers. Unless you are making your own OS or using some tough guy Linux distro.

My understanding of how EOS achieves massive transaction speed / scalability is that it delegates block production to a single actor for each block. How is block forgery NOT possibly a problem? I've read the explanations and it's somehow 'the longest chain wins' like Bitcoin ... but I don't see how that actually applies in a 'one actor per block' scheme? One actor just forges, block is hashed, boom, done: nobody the wiser. Hope my question makes sense :) and I'd love to know the answer! Big fan of EOS in all other ways than this lingering doubt.

Bitcoin works same way, one actor per block. Bitcoin uses hash and pow for signature which can be forged by anyone willing to spend as much pow, DPOS uses private key signatures which cannot be forged without hacking an account.

In an era of permissioned blockchains gaining favor with financial institutions over decentralized, freely trading cryptocurrencies like Bitcoin, Ethereum, or Ripple, Safe Cash is one of the first blockchains to be commercially viable that can meet the transaction processing speed and throughput requirements of today's market. Safe Cash employs instant settlement in under five seconds, improved security, and controlled consensus that does not rely on miners or any intermediary coin that must be purchased. It allows banks to wean themselves off the high-priced, inefficient SWIFT network that can take days to transfer money. Banks can have their own "white label" blockchain that they control and manage. Inter-bank settlement can be achieved with multi-currency wallets, a separate bank settlement blockchain, or a combination thereof, depending on bank requirements and legal compliance.

Hi man, I'm a software developer and it seems complicated to me too at the moment! Some of the whales decide to decline a payout when posting. I guess they feel they have enough Steem, and don't want to take away from the broader distribution to the smaller players.

I put 0.5 ETH into the ICO on day 1. Just checked the contract address on Etherscan and with 14 hours left of the initial 5 day period 455,000 Ether have been received. Say another 45,000 ETH is received before the end of the period and the total ETH received is 500,000 I will end up with 400 EOS tokens based on my 0.5 ETH contribution. Is that right? When can they be claimed? At the end of the 5 days or at the end of the entire 300+ day period in which coins are being offered?

You will get 200 eos because you participated with 0.5 eth. (200000000 eos / 500000 eth) * 0.5 eth

You can claim them any time after the end of the 5 days period.

The way I understand it is the amount of tokens you received is fixed. The value of a token will of course fluctuate.

I don't think you need to 'claim' them since etherscan.io already shows them being transfered to you.

Replace YOURADDRESS with the address you sent from.

I hope someone will comment if I have this wrong.

Really nice this. I wish to start experimenting with genetic algorithms kind of stuff on EOS. Then I will also like to test simple codes to gather data from multiple sources and concentrate them on a single database. The usage from EOS on this last one is that I need to do some processing on the fly before storing the results, and by using EOS makes it perfect to loose the dependency of having a computer or expensive computational device near the collection source.

Been waiting on c++ based crypto, this is the only real way get super fast transaction speeds, will have further look at the doc but I know NEM is trying to do this same thing because they found out that Java based script is not good enough especially when it's derived from c++. Plus better to do this on the machine level anyway. Like what I read so far, yes it will be bugs but all cryptos have some bugs in it.

Hey Dan!!! I came by to learn some more and say have a good weekend.

You must be stoked about the Poloniex news I broke on my page today about 10 mins after they finally released the stranglehold on everyone's BTS wallets for like 100 years slight hyperbole ---- they still cannot find the 500 SBD I transferred to them a week ago and I cannot reach them.


Like with BTS, I am still telling people to check it out, sending people over -- I am still learning.

It is our Canadastan Day long weekend here like your Almost Independence Day there coming up.... I wish you the best always, some rest and fun and stay strong man.

I am always rooting for you!!!

That's great, @dan! I'm very excited about EOS. I just learned how to participate in the EOS token sale yesterday and bought some tokens that I should be able to claim on July 1st. Exciting times and I think it's great that EOS tokens will be distributed out over a full year. That's actually the main reason why I feel a smaller investor like myself even had a chance to invest. My plan was to forgo the whole ico sale scene entirely as I didn't feel I would even be able to get in, until I heard about EOS that is.

Hi Dan, thanks for your informative post. perhaps you can shed some light on this at a noob level for me please, I followed the steps to purchase some tokens during the crows sale using the MetaMask wallet in chrome, from the metamask wallet while logged into the https://eos.io/distribution/ website I transferred ethereum to the EOS distribution address provided, but in the intructions it didn't actually stipulate whether you need to generate a EOS public key first, so I didn't, once I had already donated around $50 worth of ethereum to test this procedure it looked like it wasn't complete so I selected to generate the EOS public key and to generate this key I had to donate another small amount of ethereum, there was no way to generate this key without donating more ethereum so I did, and now I'm left with a complete process. I have my EOS public key, it looks like the full amount of money has reached the EOS distribution address but my Token balances and the "Your ETH" section below in the screenshot do not match? did I need to be concerned by the order in which I've done this process? I'm kinda worried I wont get to claim tokens worth the full amount of initial investment once they get distributed, apologies for the long winded question but I figured you would probably be able to help with some info? thanks Dan.

80K TPS is incredible! Well done! And I thought I was all cool today having made a simple little He-Man finding Skeletor game. Now I feel like a complete programming novice, lol.

Instead denying payout, you could use the money for a good cause etc..

it looks like EOS has a very good start (+257 % today), will be interesting what they will do with the first big wave of interest

I bought some EOS a few hours ago at Bitfinex. Went very smooth, Bitfinex is a class exchange. I bought based on Suppoman's youtube video. He's a steemer too. Hope it makes top 3 coins soon. :)

Great post ! Today i just lost my job...i worked really hard as a waiter for like 10 years in a restaurant...worked night after night shifts but still they decide they don't need my services anymore and that they don't have money to pay me so they just kick me out . It was really hard for me to find this job because i don't have much education....i did't go to college...
The real problem is that i have a debt of 759 $ to my apartment rent and if i don't pay till the end of the month they gonna kick me out from my own home. I don't have friends and my family won't lend me any money...
My only hope now to raise this money is steemit...i like it alot here and the community is very nice...

Please if anybody would like to help me , a upvote would be awesome and would help me tremendously to raise the money i need .

Thank you very much for your help and i hope you have a great day .

What do you guys think? After we like 4-7x our profits sell it and buy back after a year when it goes back down instead of holding for a whole year?>

Bitcoin has a lot of similarity. Bitcoin we use our own footprint, which can be plagiarized for other investors. DPOS uses fingerprints that are totally private and difficult to decipher, which makes it safer according to @dan

HI. nice to meet you. this is Brian Liu from China. i read a lot about your blog,you have many fresh ideas.

Here in china we are developing a Blockchain community named bihu, website is www.bihu.com, where people can communicate and share new and innovative ideas.

I'm thinking about translate your blog and post it on the community if you agree, just sharing knowledge with people, it's not for commercial purpose.

I'm looking forward to your early response.
