Hi, has anyone tried to compile with success bitcoind for nas synology DS211j (arm)?
I'm going crazy!

That looks quite promising. A bit techy, but seems like it can be pulled off.
Still, I'd have to put quite a few pieces together myself and I'm not really interested in downloading someone else's work as this would be a perfect place to implement a trojan horse to empty the wallet.
In my opinion the perfect scenario would be if the Bitcoin team officially offered this as a downloaded package I could trust, but that's probably pretty far down on their TODO list.

Assuming you are running another node who's output you trust you could use the assumevalid option to speed things up perhaps:

Quote

assumevalid= If this block is in the chain assume that it and its ancestors are valid and potentially skip their script verification (0 to verify all, default: 00000000000000000013176bf8d7dfeab4e1db31dc93bc311b436e82ab226b90, testnet: 00000000000128796ee387cf110ccb9d2f36cffaf7f73079c995377c65ac0dcc)

You would specify a more recent block than the default of course.

Or also copy over an up to date blockchain directory from a node you trust.

I still have a try on this moment although it's nothing worth trying at all Tongue

I originally want to save the power/time from syncing data, which use my DS115j to get latest blickchain files 24/7 and docking my laptop with faster synchronization when needed.

so I didn't compile wallet and gui(qt) in my case.

here's my platform:
VMWare Ubuntu 64 bit 16.04 netboot only with openssh
Host CPU: 4 of 8 core intel xeon E3-1505M v5
MEM: 4GB

and here's the processes, and it's taking about 20 minutes

Code:

# unnecessary installation but useful
apt-get install sudo ssh vim ntpdate screen htop iftop nmap bzip2

# compiling tools
apt-get install make binutils xutils-dev libc6-i386

# cross compiling tools
apt-get install g++-arm-linux-gnueabihf curl

# bitcoin needed
apt-get install git-core autotools-dev automake pkg-config bsdmainutils build-essential autoconf libssl-dev libboost-dev libboost-chrono-dev libboost-filesystem-dev libboost-program-options-dev libboost-system-dev libboost-test-dev libboost-thread-dev libtool libevent-dev

# bitcoin optional
apt-get install miniupnpc libminiupnpc-dev libzmq3-dev

# create working dir
cd ~
mkdir ds115j
WDIR=/root/ds115j
DIST=$WDIR/dist

# prepare your toolchain file to working dir (says xvf armada370-gcc493_glibc220_hard-GPL.txz is for DS115j in my case)
cd $WDIR
tar xvf armada370-gcc493_glibc220_hard-GPL.txz

# setting the variables
cd $WDIR
export PATH="${WDIR}/arm-unknown-linux-gnueabi/bin:${PATH}"
export CC="${WDIR}/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc"
export CXX="${WDIR}/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-g++"
export AR="${WDIR}/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ar"
export LD="${WDIR}/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ld"
export RANLIB="${WDIR}/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ranlib"
export CFLAGS="-I${WDIR}/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/include"
export LDFLAGS="-L${WDIR}/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/lib"
export LINK=$CXX

# specify your target version of bitcoin (says 0.14.1 in my case)
export ver=0.14.1

# cross compiling related tools
cd $WDIR
git clone -b v${ver} https://github.com/bitcoin/bitcoin
cd bitcoin/depends
make HOST=arm-linux-gnueabihf NO_QT=1 NO_WALLET=1 -j4

# cross compiling bitcoin
cd ..
./autogen.sh
LDFLAGS="-static-libstdc++" \
./configure \
--prefix=`pwd`/depends/arm-linux-gnueabihf \
--enable-upnp-default \
--enable-glibc-back-compat \
--enable-reduce-exports \
--disable-wallet \
--with-gui=no
make -j4
make install

# packing
cd depends
mv arm-linux-gnueabihf bitcoin-${ver}-arm-linux-gnueabihf
tar -c ./bitcoin-${ver}-arm-linux-gnueabihf/ | gzip -9 > ./bitcoin-${ver}-arm-linux-gnueabihf.tar.gz

after that, you can copy your bitcoin-${ver}-arm-linux-gnueabihf.tar.gz to the DS115j

I am interested in continue this topic because I try to install a Bitcoin node in a Synology and it is the nearest information to do it that I have found.

If someone has new information about this I will feel happy if he/she shares with us.

I'll try to follow this guide step by step and I will tell here my progress.

I gave up on this idea. My ARM-based synology has only 512 MB of RAM. This is less than what bitcoind used to take on my desktop. Maybe it is better now.

If you run the configure script with --disable-wallet, make will build a bitcoind executable that consumes only ~200 MB RAM.

The processor will still get tortured by the verification. Possibly the use of Intel low power chips with libsecp256k (the Bitcoin Core developed crypto library) verification code could make this sort of idea more practicable, but it'd be wise to wait until that code is being used in the main client (apparently the library is only used for signing txs in 0.10.0)

Still the ARM processor is slow and it will take a long time to catch up with the block chain (if it will catch up at all). Maybe one can "pre-index" the blockchain by copying the .bitcoin/blocks directory from another computer. I'm not sure if the index can be ported over to a different architecture, though.

I thought about making a non-verifying bitcoind that just stores the blockchain without doing any checking at all (or at least avoid the most expensive ones, like signature and UTXO checking). Then use an SPV client that connects to this bitcoind. This avoids leaking any information about the transactions you are requesting and it still has the security of SPV. I haven't started doing anything in this direction, though.

If you have a x86-based synology with 2 GB of RAM then you should be able to run bitcoind out of the box.

use Plex.
I want to see if it will decrease the use, when bitcoind end of download ... we will see ..

When you say video streaming do you mean Plex or Video Station? That's too bad about RAM usage, but I'm actually thinking of upgrading my NAS. I can especially justify it if it can host the blockchain for me!

Hello, I had to stop because, as you can see from the post above, the version I had compiled was the ultra-prune and was clobbered.
Now I have compiled 0.7.2 and began again to download the blockchain. At this time are the block number 15432. At the download has worked 100% cpu but now it is the ram that is consumed much.
My nas use it as a video straming and while doing this work, I just finished looking at the film "The Watch" without a hint of problems .. Wink

Holy crap ziomik. That's awesome. How long did it run at 100% CPU before it finished verifying the blockchain? I'm tempted to give this a shot.

I have a strange answer bitcoind running. I have not found solutions. Aid?

The purpose is not to generate bitcoin, but having a personal wallet I'll put on the network and will manage through the web wherever I am.

Why bother, all you would do is increase the CPU temp of the synology , causing it to NOT enter the sleep mode, thereby using MORE electricity than you can earn from generating bitcoins.

Yes, you are running the ultra-prune version.

I was just letting you know that there have been reports of this version corrupting wallets, and that it's a fairly big code change, so it might not be as stable as the official releases. So if you want to run bleeding edge, this is the version to get. If you want stable, it might be better to grab an official release like 0.7.1 and building that.

Isn't the ultra-prune in action. I downloaded the sources from the official github..

Code:

git clone https://github.com/bitcoin/bitcoin.git

Maybe I misunderstood, what you want to tell me? Undecided

Looks like it downloaded 640 MB in 24 hours. But I don't think it verifies any transactions until block 190,000 (the latest check point). After that it will probably slow down significantly.

Also, note that you seem to be running the ultra-prune version (which you should, since it has been merged to main), which has been known to corrupt wallets. Just a heads up.
