PSA: If someone not you can reverse your transaction, that means you are using a centralized, trust based system

“Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for nonreversible services. With the possibility of reversal, the need for trust spreads. “

“We consider the scenario of an attacker trying to generate an alternate chain faster than the honest chain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such as creating value out of thin air or taking money that never belonged to the attacker. Nodes are not going to accept an invalid transaction as payment, and honest nodes will never accept a block containing them. An attacker can only try to change one of his own transactions to take back money he recently spent”

Bitcoin: The Trust Anchor in a Sea of Blockchains

Bitcoin has a number of properties that give it utility (and thus value) such as trustlessness, permissionlessness, transparency, and immutability. When you broaden your perspective of bitcoin from a currency and payment system to that of a secure historical ledger, it becomes clear that these properties, in conjunction with each other, can enable powerful applications.

Is Trezor really that secure?

I am aware that Trezor’s code is public, but how sure can we be that when I am updating the Trezor firmware is in fact the code that is publicised. What stops them from stealing my keys during code update?

Fred Ehrsam from Coinbase commenting on Ethereum vs Bitcoin

https://www.reddit.com/r/ethereum/comments/4u4t73/im_fred_ehrsam_cofounder_of_coinbase_ama/

An AMA that he did on the Ethereum reddit. Below is the most interesting comment I found.

[–]FredEE[S] 19 points 13 hours ago

One major existential risk is what I described in my blog post a while back: It\’s possible that it’s better to keep the base transaction layer dumb for scaling reasons (i.e. Bitcoin) with advanced logic in higher layers. The reason so many amazing things are happening in Ethereum right now is it gives you the base transaction/store of value layer and the advanced scripting layer in one out of the box, so it’s way easier to build dapps in Ethereum right now. But maybe those things are better separated long term.

Second would be that Ethereum has a serious security issue as it is (correctly so) in move fast and break things mode which is unrecoverable. I am OK with this risk though: don’t put in more money than you are willing to lose, and whatever the issue is can likely be resolved, new version of the network spins up a month or two later.

HD address generation seems to work in bitcoin 0.13.0rc1 :-)

“The only people who should be running fully synchronizing nodes are miners and businesses and uber-geeks like theymos who enjoy fiddling with technology.”

Gavin Andresen

Compiled bitcoin-0.13.0rc1 from source on Ubuntu.

Like in older versions, there was no menu visible in bitcoin-qt (it was in the binaries) but I finally solved it through:

sudo apt-get remove appmenu-qt5

I then added the following code:

https://github.com/bitcoin/bitcoin/pull/8206/files

so I could dump the extended private master key (xprv….) and recompiled.

I then checked some of the addresses generated in bitcoin-qt here:

https://github.com/bip32JP/bip32.github.io

Substituting the BIP32 Extended Key and using:

Custom Path: m/0’/0’/0′ (for the first address, etc.)

THEY AGREED!

Thanks, core developers and especially:

Jonas Schnelli

It’s nice not having to worry anymore if your wallet.dat file has become outdated.
