Hi,

I have sent some BTC several hours ago. Got 14 confirmations @ blockchain.info, yet no money received at ico.lisk.io - What happens ?

-Technologov

The wallet with 100 BTC is my, and after being alerted by Dave Bitcoin from Wallet Recovery Services, I decided to move my coins elsewhere.

The wallet was stolen from me in 2013, when I forgot it on one of my FTP servers.

Hi All !

I'm designing a new experimental TCP/IP stack, more powerful than IPv6.

My questions is: Are there any blockchain-related features, that should be considered to be added at the IP layer ?

In some cases adding app-specific features may improve performance.

I decided to publish a small Crypti Architecture Q & A with Boris Povod (crypti dev) as compared to Ethereum's architecture.
Crypti is a Dapp platform, similar to Ethereum, but using sidechains + javascript node.js.
So what are the differences?

Q: Technologov 12:52
 
Math.random() prolly needs to be disabled for Dapps. A deterministic version needs to exits, based on blockchain hashes.
Same for opening TCP/IP sockets.
That is: Dapps should have reduced API.
Docs say: "If the above rules are not adhered to, the sidechain will most likely fork". This needs to be avoided at the API level.

A: boris.povod 13:00
> based on blockchain hashes.
What you mean?

Q: Technologov 13:00
Ethereum has special random generator API, which uses previous block hash as random number. This way RNG is 100% deterministic.
Smart idea.

A: boris.povod 13:01
@Technologov: based on previous block hash is not random number
@Technologov: it's can be attacked by miners
@Technologov: there is another good idea of random numbers 😛 Same from Eth guys

Q: Technologov 13:01
But no better way exists anyway.
And all code needs to be deterministic (to prevent chain forks).

A: boris.povod 13:02
@Technologov: there is deterministic code if you look at toolkit, but when you as developer write some logic code for your sidechain, you can make there mistake
Q: Technologov 13:04
Another risky stuff: opening TCP/IP sockets. This is disabled in Ethereum (because it is non-deterministic).
The right way is to push 3rd party data (like prices of BTC/USD, or weather, or president elections) into blockchain by Oracles. Then it can be used by blockchain contracts.

A: boris.povod 13:07
@Technologov: for tcp/ip sockets we will use seccomp to block low level calls, just we didn't added it yet 🙂 Same for 3rd party data

Q: Technologov 13:09
How about endless loops ? Is there a mechanism to prevent them or limit them ? Or it will kill sidechain ?

A: boris.povod 13:11
There is javascript, no new language, because for sure you can write there endless loop. But it's pending on developer who work with toolkit

Q: Technologov 13:12
And what about Dapp updates ? Is it possible ?

A: boris.povod 13:14
Maybe later we will make special lang based on javascript.
We working on it now, there is still testnet, after current release we will releases few new versions to make DApp updates possible and we will make polish work

Technologov: Thanks !

P.S. BTW: Crypti uses sidechain for every Dapp, which potentially makes it more scalable than Ethereum. bonus video: https://www.youtube.com/watch?v=O9o5X4xHJnc

hi all ! Sia v0.4.7 doesn't sync. Opened bug report
https://forum.sia.tech/topic/14/sia-sync-problems

BitYes exchange needs to be removed from computations of BTC/USD rate at CoinMarketCap.com
Reason: it is defunct, and shows only $ 227.62, when in reality price is closer to $270.

Is there a way to trade Siastock (Siafund) ?

2 years and no spikes !

How much coins on exchanges ?

Forks are necessary. Just like a vote-of-no-confidence and new elections in democracy, or revolution in dictatorship, or Civil War if everything else fails and no consensus if reached.

Let's look at open-source forks history:

1. OpenOffice -> LibreOffice (95% users and devs migrated)
2. XFree86 -> Xorg (100% users and devs migrated, after license change)
3. Emacs editor to XEmacs (30% migrated), old fork still has advantage. But for editors, consensus is not required.
4. Glibc to Debians glibc (70% migrated), Debian +Ubuntu. The forks are compatible.
5. GCC compiler to EGCS to new GCC compiler (100% migrated, old maintainer was fired from FSF "Free Software Foundation" by Richard Stallman, the neck-bearded old man, that does endless loop in 8 steps. Old maintainer refused to accept new Intel Pentium optimization patches and didn't move his ass).
6. Linux Kernel has mini forks all the time, like Xen kernel, OpenVZ kernel, real-time, hardened security kernel and openSUSE AppArmor kernel. No major forks in horizon, which means it is well managed. (99.9% users use the standard Linux kernel, with small optimization/bugfixes by distro). Xen and AppArmor patches upstreamed into standard Linux kernel.
7. GDB, GNU debugger, had 400 forks in the 90's, which were all merged back into new GDB. (100% migration)

In short, forking is part of the open source community. What matters here is not just the code, but the community that stands behind it. I was also scared shitless when I heard, that XFree86 project ceased to exist. I feared no Red Hat Linux desktop anymore, but little I know, that Open-Source projects do not really die this way. Later I realized, that Red Hat (and others) would not allow X11 desktop to fail, as long as there is demand for it, even if among Linux developers. In the end all development continued under the Xorg umbrella, and XFree86 project died.

Open-Source projects can only die if there is no maintainer / no big demand among users.

In case of Bitcoin, old BTC, we will receive 1 new BTC and 1 new BTX (Bitcoin XT), and community will decide which is the best. Wallet backup is compatible. As long as there is community, it would have value. But temporary crash is possible due to panic selling. Long-term damage is unlikely. (assume a dude with an ancient physical Bitcoin or an old wallet backup falls asleep for 10 years, and wakes up in 2025 - his Bitcoin, or Bitcoin XT will probably be worth more. ) So, I don't believe in chicken little and the sky is falling mania-depressia. Open Source history teaches us a solution.
We can discuss those examples of ancient forks in detail. I studied it few years ago.

Best wishes,
-"Technologov", Open-Source community member. 23.07.2015.

Disclosure: I vote for large blocks. Let's try to reach consensus in Bitcoin core, and if not -- I vote for Bitcoin XT.

Hi,

I know when difficulty adjusted higher, more zeroes need to be put in the block hash, like 0x0000...
But adding one more zero bit doubles the difficulty. 2x.
How does Bitcoin handle slight difficulty increase, like +10% ?

Thanks in advance
-Technologov

Thanks.

Hi all,

Someone is offering to sell physical Casascius Bitcoin (1 BTC, of 2013). Fully loaded.

What should be the fair price today of such item ? (considering they are no longer in production)

Hi,

I'm looking at advanced Crypto 2.0 platforms.
And so far StorJ is building decentralized, incentive-based file storage system, based on StorJ blockchain, that I can understand.

But Maidsafe seems to offer similar functionality (coin + app platform + file storage), without a centralized ledger, without a blockchain !

Anyone understands how can it possibly work?
If a client connects to the network, how the network can find his files? Or his coins?

Nope, not a miner.

Tried several servers; same error.

v1.9.8
I get error {u'message': u'', u'code': -25}
Cannot send my Bitcoins anymore

any ideas?

>Why do people insist on coming up with ideas without at least taking the time to read the whitepaper and understanding the basic concepts first?

I did read the whitepaper twice. And what ? It is way too short, and lack details.
