[SKY] Skycoin Launch Announcement

[hannusolo]

Update:

The Skycoin blockchain programming language CX, now has OpenGL support and key input support.

https://cx.skycoin.net



In theory, we will be able to embed video games (like poker or real money multiplayer dwarf fortress) on the blockchain. But we still have to figure out how to do random number generation on blockchain and on-going R&D.

We will be able to get the block time down to 200 ms per block (5 updates per second), which is almost enough to run FPS games on. With independent chains for the game and using a variant of Skycoin's Obelisk Consensus Protocol with leadership election and fall over for consensus.

In contrast, Ethereum block-times cannot be less than 30 seconds and has an inconsistent or random block rate that precludes applications for turn based video games

We have proposals to get down to 33 ms per block which is enough for 30 physics updates for second.

We might want to implement multiplayer Sim Ant on blockchain and do some test cases for multiplayer gaming.

In the CX model, each game object is a software object. Each game object exports "affordances" which are actions that can be invoked upon the software object. Affordances have restrictions and invariants checks for when they can be invoked (by who, under what context and under what conditions).

For instance, an object representing a ledger for a pile of money, might only allow the "send money to" command to be invoked if signatures/public key validation passes (the owner of the pile of money, signed the affordance or operation). Or a player in a poker game can only invoke or commit to a move, for their own player (verified by a signature) and is unable to make moves for other players (because of inability to fake the signature for the public keys for the the other players in the game).

One of the reasons we chose a cluster architecture for Skywire, is that we expect to be running thousands or millions of independent blockchains, with each application having its own blockchain running at a different tick rate over a different set of servers. We are not trying to force every application on to one giant blockchain, like ethereum. We are only forcing users to subscribe to applications which they are using, instead of replicating the data/transactions for every user on Earth.

Very interesting idea, gaming on blockchain By the way in my opinion 200 ms lateny is way too much for an FPS game, even 33 ms is too high IMO. As I see this would be the base latency of the core network, but there would be some latency on top of it from the client side as well, or not? (My knowledge is limited so it's just a guess)

Any news on how long will take cryptopia to update the wallet? I bought some SKY over there because you can't buy anywhere else (or at least only this exchange is listed on coinmarketcap.com) and i wait for 3 days to withdraw to my wallet to get coinhours. Usually is taking this long or this time they have some issues?

Same issue, can devs contact cryptopia to fix this issue.

Wallet version 0.20.3 is published on the website now.  If you had problems with block syncing on windows this should fix it.

We contacted Cryptopia yesterday about their withdrawal lock.  It looks like they have enabled deposits/withdrawals again.

this stupid if someone will have to store that data..
many you kno how much such shit you nned to store and multiply x1000... PC and noone really needs that data.
This have sence when you want make some opereation trustles but data cannot be stored forever but like 500 bloks

Skycoin, the third-generation cryptocurrency of alternative P2P project Skywire, announces several updates, including a new mobile wallet, new logo and site revamp to reflect its ever-evolving branding and design. Approaching its fifth year of development, Skycoin continues to pursue a “new Internet” under an overarching goal to implement Bitcoin’s original vision and address its underlying problems.

October 26, 2017 Zug, Switzerland: One of the oldest crypto projects in development, Skycoin is an infrastructure project rooted in the basic founding concept of Bitcoin: decentralization. Unlike the peers of its time, it was not forked from Bitcoin nor is it merely another ETH-based token. Instead, Skycoin was built using a completely original and unique codebase, featuring a revolutionary consensus algorithm dubbed “Obelisk” that bore none of the PoW/PoS similarities of most other alts, eliminating the need for miners and operating instead on a Web of Trust.

Great job, Skycoin team.
I wish it will be among top 10 cryptocurrencies in 2018.

Dev please contact cryptopia again the wallet is locked

damn it. I got some Skycoin there.

How does Skycoin solve scalability problems?

The project is very interesting, but I must say there's another one with very strong tech, which was also being developed for 4 years, the one which had DAG first actually, but then abandoned it due to its scalability problems. I'm talking about Radix (formerly eMunie), which is coming out this year. They already have made their first private deployment live in one of the 2017 YCombinator startups.  Not a pilot, trial, but a real product.

If you haven't heard about it, you should have to, because it will really be a game changer, not Byteball or IOTA.

I'm always looking for interesting tech and my top 2 are Radix and Skycoin

please answer.

Also, whats the load on skycoin, in terms of how many transactions a sec? It states 40x faster than bitcoin, can we go faster? If so, when and how?

Bitcoin can handle 6 transactions per second

Ethereum can handle 30 transactions per second

Skycoin can handle +300 transactions per second.

The bottleneck is the signature verification. We can only verify so many secp256k1 signatures per second on an ARM board, before the nodes cannot keep up with the network.

The problem with these DAG, Tangle and "hashchain" coins is that they have no way of capping their transaction rate. If the number of transactions on network, exceeds the rate the signatures can be verified, then it means the network nodes cannot keep up and the network is effectively non-functioning (DDoS attack).

So for Skycoin we capped the transaction rate, at the maximum rate that a single CPU can verify in real time.

We also are implementing off chain transactions, which can support up to 3000 transactions per second, per server.

No blockchain that exists can handle the transaction rates required for a distributed peer-to-peer utility company, so we had to move these off blockchain.

The whole Ethereum network would be clogged by Skywire running with 600 users downloading videos at the same time. None of the existing blockchains or anything that is an ERC20 token, can handle the required transaction rates (Which are hundreds of times orders of magnitude higher than the rate ECC signatures can be verified).

Skycoin is doing off blockchain payment channels, that use a special one way hashing function, that is much faster than ECC or secp256k1 signature verification (hundreds of thousands per second, instead of 5,000 signature verifications per second). And for small payments less than 1 penny, most of the transactions will be running on this.

It is useless to have a tangle or "Hashchain" that can handle 1 million transactions per second, if a single CPU can only verify 5,000 signatures per second! The computers in the network cannot even verify the transactions, so it does not make any sense.

Also, another problem and reason these ERC20 tokens wont work, is that the transaction fees on ethereum are millions of times higher than the cost of the micro-transactions for doing a distributed ISP. It just wont work.

>even 33 ms is too high IMO.

Ethereum is 30,000 ms. So going from 30,000 ms to 200 ms or 33 ms is a major improvement.

Normal network latency for an FPS game is 200 to 300 ms for network latency.

For physics updates, games run at 20 ticks per sond, 30 ticks per second or maximum of 60 ticks per second. Most physics updates are at 30 ticks per second or 33 ms per tick.

The performance, exceeds what is necessary to embed counter strike on blockchain.

200 ms, is below what humans can even perceive, for the purposes of poker and non-real time games.  Even 500 ms is fine for these games.

Going below 200 ms for block timedoes not add any benefit if the average network latency is 300 ms.

Skycoin was designed for the blockchain to be pruned.

These games wont be stored on the main blockchain, but on independent blockchain. And they can choose to retain only a day, an hour, a month, or a few minutes of the data.

Skycoin is one of the first chains that was designed to allow the old data to be pruned efficiently (we use UXTX instead of UXTO). This is one of the major improvements of the data structure Skycoin is using for transactions, over Bitcoin.

Hello.

Are you referring to this also?

https://bitcointalk.org/index.php?topic=1598745.0

http://www.swirlds.com/
and

They claim more than 250000 tx/s without require POW and
which can be only limited by network bandwidth.

Yeah for non-actio games, like card games, etc it is quite ideal. But keep in mind that nowadays gamers love high fps, there are gaming monitors for 144hz, I think it is unnecessarily too much, but marketingwise, if everyone is running a game ~100 fps, than they won't like the low net tick rate IMO

I hope that is a legit integration problem with skycoin and not something funny. I'm using cryptopia for the first time and I don't really appreciate the adrenaline rush

We really need to get skycoin on a decent exchange.
