Original Topic: Exploring alternative full node implementations - Gocoin
Author: ABCbits
Intro
I dey inspire by di tiltedIceCream reply[1] for thread "Why dey no encourage other way to implement am?"[2], i dey inspirited to try another way Bitcoin full node to do am. Based on Jameson Lopp benchmark[3], Gocoin look to get good performance so i decide to give am a try.
Basic info
My system
Compile and installation
Di documentation[6] just mention i need git and golang for my system. Since e no mention required golang version, i just use golang provide for my distro. I receive golang 1.18.1 which na just small e old dan di new version (1.18.4[7]).
As i read tweak page[8], Gocoin also support di use of external secp256k1 library from Bitcoin Core. So i decide to install secp256k1 for my system and clone Gocoin 1.10.1.
Use Gocoin to take build-in benchmark, external secp256k1 library get 40% faster performance for my system. So i decide to use di external secp256k1 library to take copy sipasec.go to parent directory.
Finally na time to compile Gocoin. You fit just compile di client to run full node, but i try to compile everything. E dey straightforward and e only take few seconds. Both client and wallet compiled no get problem, although 5 external Gocoin fail to compile. I just manage fix utxo_compress and utxo_decompress after I use di latest code from Gocoin latest commit.
Initial Block Download (IBD)
Here na my gocoin.conf wey mashed togeda from Jameson Lopp blog[3] and Gocoin documentation[9-10]. I also configure Gocoin only connect to my Bitcoin Core node. gocoin.conf e should dey locate on directory whr you run/launch client file.
Di sync process dey take about 6.8 hours. As expected, HDD na di only bottleneck for sync process whr my Bitcoin Core report send speed na 11-18MB/s speed. Gocoin RAM usage after IBD na 23.1GB, although e dey reduce to 19GB after i close and open Gocoin again. Directory size of Gocoin na about 354GB, while Bitcoin Core na about 493GB (txindex, blockfilterindex, coinstatsindex enabled). I go talk say Gocoin web UI e dey good.

Basic info
- Dey write am for Go language (golang).
- dey only develop am by piotr_n[4].
- e get both full node and wallet function.
- dey develop am since 2013[5].
- Gocoin load all UTXO for RAM.
My system
- Debian-based OS
- Old 6 core CPU
- 32GB RAM
- 3.5" HDD (Both Bitcoin Core and Gocoin data stored here)
- Bitcoin Core 23.0
- Gocoin 1.10.1
