Configurar Nó Bitcoin em 2023

Nó Bitcoin em 2023

Dez anos depois de ter tido pela primeira vez um nó Bitcoin completo, decidi voltar a montar um nó completo Bitcoin. Além de querer ver como era agora o processo, decidi montar um nó para abrir a possibilidade de experimentar outras funcionalidades do Bitcoin, como o tão falado LN. O que posso adiantar é que não ocorreram grandes mudanças de configuração, desde 2013 até agora.


A Instalação
Eu estou a usar o Windows 11, e escolhi instalar num disco SSD 1TB. E obtei por usar o principal software para o nó Bitcoin, o mesmo que usei em 2013, o Bitcoin Core na sua versão mais atualizada (logicamente). O download foi feito no site oficial: https://bitcoincore.org/en/download/

Normalmente costumo escolher a opção sem instalação (zip), mas desta vez optei pela versão instalação. E depois, bastou seguir os passos indicados, com o "apoio" do tutorial oficial: https://bitcoin.org/en/full-node#windows-10 (vou admitir que olhei pouco para o tutorial, mas estava aberto para alguma questão).


A Configuração
Foi aqui que as coisas são um pouco diferentes, do quem 2013. A primeiro janela que aparece depois de abrir o Bitcoin Core pela primeira vez, é o seguinte:


Nesta janela podemos escolher se queremos guardar o blockchain na pasta predefinida ou noutra pasta a nossa escolha. Aqui escolhi o disco que pretendia usar para o blockchain.
A janela tinha ainda outra opção, que era escolher entre ter o nó completo, e o nó podado. O nó podado - algo novo para mim, é a possibilidade de apenas fazer o download e manter no nosso nó os últimos blocos do blockchain, até ao espaço defino por nós. Por defeito ele recomenda 2GB que dará +/- para 6 dias de blocos. Isso faz com que ele esteja sempre apagar os blocos mais antigos, a medida que faz o download dos novos. Aqui escolhi o nó completo, que iria ocupar na altura uns 540GB.

Esta janela de opções, foi a principal diferença que me lembro de 2013. Na altura, julgo que não era dada a opção ao utilizador de escolher onde queria guardar o blockchain, tendo de fazer esse ajuste manualmente nas ficheiros raiz do Bitcoin Core. E também não havia a opção de nó podado, até porque o nó completo ocupava pouco espaço.


O Download
Configurações definidas para o nó, começa o download de 14 anos de blockchain:


Tenho uma boa ligação a Internet, em fibra ótica, e uma velocidade de download 500 Mbps. Mas claro que não depende só da minha ligação a internet, mas a da velocidade de upload da rede. Nesse sentido download de todo o blockchain (540GB) demorou umas 16-17 horas.


A Seguir
Desde o dia 6 de Outubro que tenho um nó completo do Bitcoin a rodar no meu PC. É bom contribuir para a rede, apesar do meu nó ser apenas a "gota" num oceano. Agora, vou fazer algumas experiencias, em configurações do nó e testar outras possibilidades, como configurar a minha carteira Electrum ao meu nó - depois irei partilhar.

Outra coisa, que ainda não fiz, foi abrir a minha primeira carteira que tive em 2013. Será que vai ser como aquele dinheiro que encontramos no bolso de umas calças que estavam guardas a vários meses/anos? Veremos...

Boa joker_josue, já configurei o nó uma vez, na época ele tinha cerca de 200 GB's, lembro que tinha um usuário aqui no BitcoinTalk que fazia um "backup" da Blockchain e upava em um site desses conhecidos de Download para que o pessoal pudesse baixar mais rápido. Pelas contas que eu fiz aqui se baixasse com a velocidade da sua internet no máximo deveria gastar cerca de 2,5 hrs. Tem um tempo de validação dos blocos também, então gastaria um pouco mais.

Mas deixar o Software fazer o processo sozinho é mais seguro e vale a pena.

Eu não continuei com o meu node porque eu não deixo o PC ligado 24/7, então nem faria sentido ficar ligado só quando tivesse usando. Você pretende deixar rodando sempre?

[joker_josue]

Por norma não desligo o PC. É um desktop então é mais fácil ele ficar sempre ligado, sem incomodar ninguém.

Basicamente, foi adicionar o nó a rodar, coisa que não puxa pelo processador e por isso não aumenta o custo de energia.

[Paredao]

Parabéns pelo tópico @joker_josue. No passado também tive um node com o Bitcoin core. Naquela época tinha paciência de ficar horas baixando o blockchain e esperando a sincronização. Hoje, com o blockchain na casa dos 540 GB e subindo, não tenho a mínima vontade em fazer isso novamente. Muito trabalhoso.

Bem, na realidade continua a ser bem simples como era em 2013. Apenas precisamos de ter espaço em disco e deixar a coisa rodar normalmente.

Por acaso, eu adicionava uma opção de poder escolher múltiplos discos, para ele ir armazenando a blockchain em discos diferentes, depois de um estar ocupado.
Onde posso sugerir isso? Na board Development & Technical Discussion?

[darkv0rt3x]

Parabéns @joker_josue. Finalmente vejo que o meu trabalho começa a dar frutos. heeh... Depois partilha aqui o teu file de configuração para podermos discutir configurações para adicionares/remover que possam ajudar o node.

Já importaste alguma wallet? Já criaste alguma? Um conselho é que tenhas um nó offline para criares carteiras/addresses novas mas que nunca se ligue à internet!

Parabéns @joker_josue. Finalmente vejo que o meu trabalho começa a dar frutos. heeh... Depois partilha aqui o teu file de configuração para podermos discutir configurações para adicionares/remover que possam ajudar o node.

Eu ainda não mexi nas configurações.
Qual é o ficheiro em questão?

Já importaste alguma wallet? Já criaste alguma? Um conselho é que tenhas um nó offline para criares carteiras/addresses novas mas que nunca se ligue à internet!

Como disse no OP, tinha uma wallet antiga (a primeira que tive) de 2013. Então ontem decidi abrir, e posso dizer que tive uma agradável supressa, que ainda tinha lá BTC. 
E eu que pensava que já estava vazia. 

Já valeu apena voltar a montar o nó!

Epá, no Windows não sei para onde é que o ficheiro vai. Mas deve estar algures numa pasta onde podes aceder se editares o caminho na barra de endereços e escreveres %appdata%. Pelo menos é para onde costuma ir muitos dos dados de aplicações instaladas. Se lá não encontrares, a gente faz aí uma investigação para descobrir! heheh


Eish... Bitcoin de 2013. Não queres vender algum ao preço que estava na altura? Ou melhor... Ainda to compro ao preço que eu comprei Bitcoin pela primeira vez. Ficas tu a ganhar e eu também... Comprei a 2990€... :p


Edited;
Esqueci-me de mencionar que o ficheiro de configuração que deves procurar tem o nome bitcoin.conf

https://github.com/bitcoin/bitcoin/blob/master/doc/bitcoin-conf.md#default-configuration-file-locations

No windows você encontra ele no: %APPDATA%\Bitcoin
Que dá o link direto: C:\Users\username\AppData\Roaming\Bitcoin\bitcoin.conf

No linux: $HOME/.bitcoin
/home/username/.bitcoin/bitcoin.conf

Entretanto, qual config?

Como eu não mexi em nada nesse ficheiro, está como vem de origem.

Não entendi.

Quem disse que esse é o caminho: a documentação do próprio bitcoin core
Que ficheiro: o dark falou logo acima (bitcoin.conf)

Vou responder quanto à configuração, já que sobre o resto já está tratado.

Existem centenas de configurações que podem ajudar o node a ser mais eficiente/rápido, dependendo do hardware em que está. Se consegues abrir o teu bitcoin.conf, copia e cola aqui para ver o que tem de origem.
E depois vemos o que se pode adicionar/remover, dependendo das necessidades!

Aquilo são mais de 600 linhas de código.

O ficheiro não tem nenhuma info mais detalhada sobre o meu node? 


PS.: Não desconfiou de ti... desconfiou da net...

A menos que você tenha alterado ele para incluir o seu IP, dados RPC, ou outra informação sensível, ele vem apenas com os parametros de configuração padrão.

Esse site é legal pois ele permite que você saiba o que está modificando e o faça mais facilmente: https://jlopp.github.io/bitcoin-core-config-generator/

Como disse, não mexi em nenhuma configuração, foi só colocar o nó a rodar. Agora é que iria começar a "mexer" nesses parâmetros, se fosse necessário.
Esse site é interessante, vou dar uma vista de olhos.

Sendo assim, aqui vai as configurações padrão:

### Connection options


# Add a node to connect to and attempt to keep the connection open (see
# the addnode RPC help for more info). This option can be specified
# multiple times to add multiple nodes; connections are limited to
# 8 at a time and are counted separately from the -maxconnections
# limit.

#fixedseeds=1

# Always query for peer addresses via DNS lookup (default: 0)
#forcednsseed=1

#maxtimeadjustment=1

# Tries to keep outbound traffic under the given target per 24h. Limit
# does not apply to peers with 'download' permission or blocks

# -noonion to disable (default: -proxy)
#onion=<ip:port>

# Make automatic outbound connections only to network <net> (ipv4, ipv6,

#proxyrandomize=1

# Connect to a node to retrieve peer addresses, and disconnect. This
# option can be specified multiple times to connect to multiple
# nodes.
#seednode=<ip>

# Specify socket connection timeout in milliseconds. If an initial attempt
# to connect is unsuccessful after this amount of time, drop it
# (minimum: 1, default: 5000)
#timeout=<n>

# Tor control port to use if onion listening enabled (default:
# 127.0.0.1:9051)
#torcontrol=<ip>:<port>

# Tor control port password (default: empty)
#torpassword=<pass>

# Use UPnP to map the listening port (default: 1 when listening and no
# -proxy)
#upnp=1

# Bind to the given address and add permission flags to the peers
# connecting to it. Use [host]:port notation for IPv6. Allowed
# permissions: bloomfilter (allow requesting BIP37 filtered blocks
# and transactions), noban (do not ban for misbehavior; implies
# download), forcerelay (relay transactions that are already in the
# mempool; implies relay), relay (relay even in -blocksonly mode,
# and unlimited transaction announcements), mempool (allow
# requesting BIP35 mempool contents), download (allow getheaders
# during IBD, no disconnect after maxuploadtarget limit), addr
# (responses to GETADDR avoid hitting the cache and contain random
# records with the most up-to-date info). Specify multiple
# permissions separated by commas (default:
# download,noban,mempool,relay). Can be specified multiple times.
#whitebind=<[permissions@]addr>

# Add permission flags to the peers connecting from the given IP address
# (e.g. 1.2.3.4) or CIDR-notated network (e.g. 1.2.3.0/24). Uses
# the same permissions as -whitebind. Can be specified multiple
# times.
#whitelist=<[permissions@]IP address or network>


### Wallet options


# What type of addresses to use ("legacy", "p2sh-segwit", "bech32", or
# "bech32m", default: "bech32")
#addresstype=1

# Group outputs by address, selecting many (possibly all) or none, instead
# of selecting on a per-output basis. Privacy is improved as
# addresses are mostly swept with fewer transactions and outputs
# are aggregated in clean change addresses. It may result in higher
# fees due to less optimal coin selection caused by this added
# limitation and possibly a larger-than-necessary number of inputs
# being used. Always enabled for wallets with "avoid_reuse"
# enabled, otherwise default: 0.
#avoidpartialspends=1

# What type of change to use ("legacy", "p2sh-segwit", "bech32", or
# "bech32m"). Default is "legacy" when -addresstype=legacy, else it
# is an implementation detail.
#changetype=1

# The maximum feerate (in BTC/kvB) at which transaction building may use
# more inputs than strictly necessary so that the wallet's UTXO
# pool can be reduced (default: 0.0001).
#consolidatefeerate=<amt>

# Do not load the wallet and disable wallet RPC calls
#disablewallet=1

# The fee rate (in BTC/kvB) that indicates your tolerance for discarding
# change by adding it to the fee (default: 0.0001). Note: An output
# is discarded if it is dust at this rate, but we will always
# discard up to the dust relay fee and a discard fee above that is
# limited by the fee estimate for the longest target
#discardfee=<amt>

# A fee rate (in BTC/kvB) that will be used when fee estimation has
# insufficient data. 0 to entirely disable the fallbackfee feature.
# (default: 0.00)
#fallbackfee=<amt>

# Set key pool size to <n> (default: 1000). Warning: Smaller sizes may
# increase the risk of losing funds when restoring from an old
# backup, if none of the addresses in the original keypool have
# been used.
#keypool=<n>

# Spend up to this amount in additional (absolute) fees (in BTC) if it
# allows the use of partial spend avoidance (default: 0.00)
#maxapsfee=<n>

# Fee rates (in BTC/kvB) smaller than this are considered zero fee for
# transaction creation (default: 0.00001)
#mintxfee=<amt>

# Fee rate (in BTC/kvB) to add to transactions you send (default: 0.00)
#paytxfee=<amt>

# External signing tool, see doc/external-signer.md
#signer=<cmd>

# Spend unconfirmed change when sending transactions (default: 1)
#spendzeroconfchange=1

# If paytxfee is not set, include enough fee so transactions begin
# confirmation on average within n blocks (default: 6)
#txconfirmtarget=<n>

# Specify wallet path to load at startup. Can be used multiple times to
# load multiple wallets. Path is to a directory containing wallet
# data and log files. If the path is not absolute, it is
# interpreted relative to <walletdir>. This only loads existing
# wallets and does not create new ones. For backwards compatibility
# this also accepts names of existing top-level data files in
# <walletdir>.
#wallet=<path>

# Make the wallet broadcast transactions (default: 1)
#walletbroadcast=1

# Specify directory to hold wallets (default: <datadir>/wallets if it
# exists, otherwise <datadir>)
#walletdir=<dir>

# Execute command when a wallet transaction changes. %s in cmd is replaced
# by TxID, %w is replaced by wallet name, %b is replaced by the
# hash of the block including the transaction (set to 'unconfirmed'
# if the transaction is not included) and %h is replaced by the
# block height (-1 if not included). %w is not currently
# implemented on windows. On systems where %w is supported, it
# should NOT be quoted because this would break shell escaping used
# to invoke the command.
#walletnotify=<cmd>

# Send transactions with full-RBF opt-in enabled (RPC only, default: 1)
#walletrbf=1


### ZeroMQ notification options


# Enable publish hash block in <address>

#rpcauth=<userpw>

# Bind to given address to listen for JSON-RPC connections. Do not expose
# the RPC server to untrusted networks such as the public internet!
# This option is ignored unless -rpcallowip is also passed. Port is
# optional and overrides -rpcport. Use [host]:port notation for
# IPv6. This option can be specified multiple times (default:

A menos que você tenha alterado ele para incluir o seu IP, dados RPC, ou outra informação sensível, ele vem apenas com os parametros de configuração padrão.

Esse site é legal pois ele permite que você saiba o que está modificando e o faça mais facilmente: https://jlopp.github.io/bitcoin-core-config-generator/

Como disse, não mexi em nenhuma configuração, foi só colocar o nó a rodar. Agora é que iria começar a "mexer" nesses parâmetros, se fosse necessário.
Esse site é interessante, vou dar uma vista de olhos.

Sendo assim, aqui vai as configurações padrão:

Code:

##
## bitcoin.conf configuration file.
## Generated by contrib/devtools/gen-bitcoin-conf.sh.
##
## Lines beginning with # are comments.
## All possible configuration options are provided. To use, copy this file
## to your data directory (default or specified by -datadir), uncomment
## options you would like to change, and save the file.
##


### Options

# message)
#alertnotify=<cmd>

# 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: 100)
#blockreconstructionextratxn=<n>

# Specify directory to hold blocks subdirectory for *.dat files (default:
# <datadir>)
#blocksdir=<dir>

# Whether to reject transactions from network peers. Automatic broadcast
# and rebroadcast of any transactions from inbound peers is
# disabled, unless the peer has the 'forcerelay' permission. RPC
# transactions are not affected. (default: 0)
#blocksonly=1

# Maintain coinstats index used by the gettxoutsetinfo RPC (default: 0)
#coinstatsindex=1

# Specify path to read-only configuration file. Relative paths will be
# prefixed by datadir location (only useable from command line, not
# configuration file) (default: bitcoin.conf)
#conf=<file>

# Run in the background as a daemon and accept commands (default: 0)
#daemon=1

# Wait for initialization to be finished before exiting. This implies
# -daemon (default: 0)
#daemonwait=1

# Specify data directory
#datadir=<dir>

# Maximum database cache size <n> MiB (4 to 16384, default: 450). In
# addition, unused mempool memory is shared for this cache (see
# -maxmempool).
#dbcache=<n>

# Specify location of debug log file (default: debug.log). Relative paths
# will be prefixed by a net-specific datadir location. Pass
# -nodebuglogfile to disable writing the log to a file.

# Specify pid file. Relative paths will be prefixed by a net-specific
# datadir location. (default: bitcoind.pid)
#pid=<file>

# Reduce storage requirements by enabling pruning (deleting) of old
# blocks. This allows the pruneblockchain RPC to be called to
# delete specific blocks and enables automatic pruning of old
# blocks if a target size in MiB is provided. This mode is
# incompatible with -txindex. Warning: Reverting this setting
# requires re-downloading the entire blockchain. (default: 0 =
# disable pruning blocks, 1 = allow manual pruning via RPC, >=550 =
# automatically prune block files to stay under the specified
# target size in MiB)

# Rebuild chain state and block index from the blk*.dat files on disk.
# This will also rebuild active optional indexes.

# instead. Deactivate all optional indexes before running this.
#reindex-chainstate=1

# Use the experimental syscall sandbox in the specified mode
# (-sandbox=log-and-abort or -sandbox=abort). Allow only expected
# syscalls to be used by bitcoind. Note that this is an
# experimental new feature that may cause bitcoind to exit or crash
# unexpectedly: use with caution. In the "log-and-abort" mode the
# invocation of an unexpected syscall results in a debug handler
# being invoked which will log the incident and terminate the
# program (without executing the unexpected syscall). In the
# "abort" mode the invocation of an unexpected syscall results in
# the entire process being killed immediately by the kernel without
# executing the unexpected syscall.
#sandbox=<mode>

# Specify path to dynamic settings data file. Can be disabled with
# -nosettings. File is written at runtime and not meant to be
# edited by users (use bitcoin.conf instead for custom settings).
# Relative paths will be prefixed by datadir location. (default:
# settings.json)
#settings=<file>

# Execute command immediately before beginning shutdown. The need for
# shutdown may be urgent, so be careful not to delay it long (if
# the command doesn't require interaction with the server, consider
# having it fork into the background).
#shutdownnotify=<cmd>

# Execute command on startup.
#startupnotify=<cmd>

# Maintain a full transaction index, used by the getrawtransaction rpc
# call (default: 0)
#txindex=1

# Print version and exit
#version=1


### Connection options


# Add a node to connect to and attempt to keep the connection open (see
# the addnode RPC help for more info). This option can be specified
# multiple times to add multiple nodes; connections are limited to
# 8 at a time and are counted separately from the -maxconnections
# limit.

# addresses would lead us to the CJDNS network, see doc/cjdns.md)
# (default: 0)
#cjdnsreachable=1

#fixedseeds=1

# Always query for peer addresses via DNS lookup (default: 0)
#forcednsseed=1

# I2P SAM proxy to reach I2P peers and accept I2P connections (default:
# none)
#i2psam=<ip:port>

# -maxconnections=0)
#listen=1

# Automatically create Tor onion service (default: 1)

# time may be influenced by outbound peers forward or backward by
# this amount (default: 4200 seconds).
#maxtimeadjustment=1

# Tries to keep outbound traffic under the given target per 24h. Limit
# does not apply to peers with 'download' permission or blocks
# created within past week. 0 = no limit (default: 0M). Optional
# suffix units [k|K|m|M|g|G|t|T] (default: M). Lowercase is 1000

# Use NAT-PMP to map the listening port (default: 0)
#natpmp=1

# Enable all P2P network activity (default: 1). Can be changed by the
# setnetworkactive RPC command
#networkactive=1

# Use separate SOCKS5 proxy to reach peers via Tor onion services, set
# -noonion to disable (default: -proxy)
#onion=<ip:port>

# Make automatic outbound connections only to network <net> (ipv4, ipv6,

# affected by this option. It can be specified multiple times to
# allow multiple networks.
#onlynet=<net>

# Serve compact block filters to peers per BIP 157 (default: 0)
#peerblockfilters=1

# Support filtering of blocks and transaction with bloom filters (default:

# Listen for connections on <port>. Nodes not using the default ports
# (default: 8333, testnet: 18333, signet: 38333, regtest: 18444)
# are unlikely to get incoming connections. Not relevant for I2P
# (see doc/i2p.md).
#port=<port>

# Connect through SOCKS5 proxy, set -noproxy to disable (default:
# disabled)
#proxy=<ip:port>

# Randomize credentials for every proxy connection. This enables Tor

#proxyrandomize=1

# Connect to a node to retrieve peer addresses, and disconnect. This
# option can be specified multiple times to connect to multiple
# nodes.
#seednode=<ip>

# Specify socket connection timeout in milliseconds. If an initial attempt
# to connect is unsuccessful after this amount of time, drop it
# (minimum: 1, default: 5000)
#timeout=<n>

# Tor control port to use if onion listening enabled (default:
# 127.0.0.1:9051)
#torcontrol=<ip>:<port>

# Tor control port password (default: empty)
#torpassword=<pass>

# Use UPnP to map the listening port (default: 1 when listening and no
# -proxy)
#upnp=1

# Bind to the given address and add permission flags to the peers
# connecting to it. Use [host]:port notation for IPv6. Allowed
# permissions: bloomfilter (allow requesting BIP37 filtered blocks
# and transactions), noban (do not ban for misbehavior; implies
# download), forcerelay (relay transactions that are already in the
# mempool; implies relay), relay (relay even in -blocksonly mode,
# and unlimited transaction announcements), mempool (allow
# requesting BIP35 mempool contents), download (allow getheaders
# during IBD, no disconnect after maxuploadtarget limit), addr
# (responses to GETADDR avoid hitting the cache and contain random
# records with the most up-to-date info). Specify multiple
# permissions separated by commas (default:
# download,noban,mempool,relay). Can be specified multiple times.
#whitebind=<[permissions@]addr>

# Add permission flags to the peers connecting from the given IP address
# (e.g. 1.2.3.4) or CIDR-notated network (e.g. 1.2.3.0/24). Uses
# the same permissions as -whitebind. Can be specified multiple
# times.
#whitelist=<[permissions@]IP address or network>


### Wallet options


# What type of addresses to use ("legacy", "p2sh-segwit", "bech32", or
# "bech32m", default: "bech32")
#addresstype=1

# Group outputs by address, selecting many (possibly all) or none, instead
# of selecting on a per-output basis. Privacy is improved as
# addresses are mostly swept with fewer transactions and outputs
# are aggregated in clean change addresses. It may result in higher
# fees due to less optimal coin selection caused by this added
# limitation and possibly a larger-than-necessary number of inputs
# being used. Always enabled for wallets with "avoid_reuse"
# enabled, otherwise default: 0.
#avoidpartialspends=1

# What type of change to use ("legacy", "p2sh-segwit", "bech32", or
# "bech32m"). Default is "legacy" when -addresstype=legacy, else it
# is an implementation detail.
#changetype=1

# The maximum feerate (in BTC/kvB) at which transaction building may use
# more inputs than strictly necessary so that the wallet's UTXO
# pool can be reduced (default: 0.0001).
#consolidatefeerate=<amt>

# Do not load the wallet and disable wallet RPC calls
#disablewallet=1

# The fee rate (in BTC/kvB) that indicates your tolerance for discarding
# change by adding it to the fee (default: 0.0001). Note: An output
# is discarded if it is dust at this rate, but we will always
# discard up to the dust relay fee and a discard fee above that is
# limited by the fee estimate for the longest target
#discardfee=<amt>

# A fee rate (in BTC/kvB) that will be used when fee estimation has
# insufficient data. 0 to entirely disable the fallbackfee feature.
# (default: 0.00)
#fallbackfee=<amt>

# Set key pool size to <n> (default: 1000). Warning: Smaller sizes may
# increase the risk of losing funds when restoring from an old
# backup, if none of the addresses in the original keypool have
# been used.
#keypool=<n>

# Spend up to this amount in additional (absolute) fees (in BTC) if it
# allows the use of partial spend avoidance (default: 0.00)
#maxapsfee=<n>

# Fee rates (in BTC/kvB) smaller than this are considered zero fee for
# transaction creation (default: 0.00001)
#mintxfee=<amt>

# Fee rate (in BTC/kvB) to add to transactions you send (default: 0.00)
#paytxfee=<amt>

# External signing tool, see doc/external-signer.md
#signer=<cmd>

# Spend unconfirmed change when sending transactions (default: 1)
#spendzeroconfchange=1

# If paytxfee is not set, include enough fee so transactions begin
# confirmation on average within n blocks (default: 6)
#txconfirmtarget=<n>

# Specify wallet path to load at startup. Can be used multiple times to
# load multiple wallets. Path is to a directory containing wallet
# data and log files. If the path is not absolute, it is
# interpreted relative to <walletdir>. This only loads existing
# wallets and does not create new ones. For backwards compatibility
# this also accepts names of existing top-level data files in
# <walletdir>.
#wallet=<path>

# Make the wallet broadcast transactions (default: 1)
#walletbroadcast=1

# Specify directory to hold wallets (default: <datadir>/wallets if it
# exists, otherwise <datadir>)
#walletdir=<dir>

# Execute command when a wallet transaction changes. %s in cmd is replaced
# by TxID, %w is replaced by wallet name, %b is replaced by the
# hash of the block including the transaction (set to 'unconfirmed'
# if the transaction is not included) and %h is replaced by the
# block height (-1 if not included). %w is not currently
# implemented on windows. On systems where %w is supported, it
# should NOT be quoted because this would break shell escaping used
# to invoke the command.
#walletnotify=<cmd>

# Send transactions with full-RBF opt-in enabled (RPC only, default: 1)
#walletrbf=1

# Append comment to the user agent string
#uacomment=<cmt>


### Chain selection options


# Use the chain <chain> (default: main). Allowed values: main, test,

# Use the signet chain. Equivalent to -chain=signet. Note that the network
# is defined by the -signetchallenge parameter
#signet=1

# Blocks must satisfy the given script to be considered valid (only for
# signet networks; defaults to the global default signet test
# network challenge)
#signetchallenge=1

# Specify a seed node for the signet network, in the hostname[:port]
# format, e.g. sig.net:1234 (may be used multiple times to specify

### RPC server options


# Accept public REST requests (default: 0)
#rest=1

# Allow JSON-RPC connections from specified source. Valid for <ip> are a
# single IP (e.g. 1.2.3.4), a network/netmask (e.g.
# 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). This
# option can be specified multiple times
#rpcallowip=<ip>

# Username and HMAC-SHA-256 hashed password for JSON-RPC connections. The
# field <userpw> comes in the format: <USERNAME>:<SALT>$<HASH>. A
# canonical python script is included in share/rpcauth. The client
# then connects normally using the
# rpcuser=<USERNAME>/rpcpassword=<PASSWORD> pair of arguments. This
# option can be specified multiple times
#rpcauth=<userpw>

# Bind to given address to listen for JSON-RPC connections. Do not expose
# the RPC server to untrusted networks such as the public internet!
# This option is ignored unless -rpcallowip is also passed. Port is
# optional and overrides -rpcport. Use [host]:port notation for
# IPv6. This option can be specified multiple times (default:
# 127.0.0.1 and ::1 i.e., localhost)
#rpcbind=<addr>[:port]

# Location of the auth cookie. Relative paths will be prefixed by a
# net-specific datadir location. (default: data dir)
#rpccookiefile=<loc>

# Password for JSON-RPC connections
#rpcpassword=<pw>

# Listen for JSON-RPC connections on <port> (default: 8332, testnet:
# 18332, signet: 38332, regtest: 18443)
#rpcport=<port>

# Sets the serialization of raw transaction or block hex returned in
# non-verbose mode, non-segwit(0) or segwit(1) (default: 1)
#rpcserialversion=1

# Set the number of threads to service RPC calls (default: 4)
#rpcthreads=<n>

# Username for JSON-RPC connections
#rpcuser=<user>

# Set a whitelist to filter incoming RPC calls for a specific user. The
# field <whitelist> comes in the format: <USERNAME>:<rpc 1>,<rpc
# 2>,...,<rpc n>. If multiple whitelists are set for a given user,
# they are set-intersected. See -rpcwhitelistdefault documentation
# for information on default whitelist behavior.
#rpcwhitelist=<whitelist>

# Sets default behavior for rpc whitelisting. Unless rpcwhitelistdefault
# is set to 0, if any -rpcwhitelist is set, the rpc server acts as
# if all rpc users are subject to empty-unless-otherwise-specified
# whitelists. If rpcwhitelistdefault is set to 1 and no
# -rpcwhitelist is set, rpc server acts as if all rpc users are
# subject to empty whitelists.
#rpcwhitelistdefault=1

# Accept command line and JSON-RPC commands
#server=1

Calma @joker_josue... 95% disso são comentários com explicações breves sobre cada opção!

O site que o @TryNinja postou é um excelente starting point! Começa por lá e vai lendo o que as opções fazem. Quando houver dúvidas, vais colocando aqui!

Repara que no final do ficheiro muito grande que postaste, tens 3 secções. São mais ou menos "auto-explicáveis" mas o que podes fazer com isso, é basicamente teres configurações individuais em cada uma daquelas 4 secções, mainnet, signet testnet regtnet, para que possas, por exemplo, rapidamente mudar entre um node na mainnet para um na regtest e etc. Bastante conveniente!

Pois é!!! 
Só reparei nisso, quando fui copiar para colar aqui... 

Vou explorar o site que o @TryNinja indicou.


O que eu agora estava a pensar fazer era configurar o nó a uma VPN. Já estive a ver, e consegue-se isso diretamente no UI do Bitcoin Core. Só ainda não testei.

Já agora, para que é que serve a opção "Permitir ligações de "a receber"?"?

Essa opção é para permitir que outros nodes se liguem a ti para poderem obter informações sobre a rede através do teu node! Naturalmente que queres essa opção activada, listen=1 para que o teu node também tenha mais facilidade em se connectar com outros peers. E é possível que tenhas que abrir a porta no teu router, se for o caso.

Respondendo a sua dúvida com uma resposta para a dúvida que a @Disruptivas teve:

- O que exatamente são os public listening nodes e o que é diferente dos nodes normais? Eu tenho uma resposta em mente, mas não tenho 100% de certeza, então quero confirmar com os senhores.

São os nodes que tem a porta 8333 aberta para requisições de entrada. Ou seja, eles não apenas recebem os blocos e ficam ali na deles, como ativamente contribuem com outros nodes. Por conta disso, tem como "encontrar" esses nodes publicamente (daí o nome).

A alternativa seriam os nodes "secretos/escondidos" com essa porta fechada, só recebendo e não contribuindo com nada.

Permitir ligações "incoming" significa que seu node vai contribuir com a rede! Você recebe e repassa, outro node repassa, etc... assim se faz a rede do Bitcoin!

Era o que eu pensava, obrigado pelo feedback.

Por acaso, não foi preciso fazer alterações no router, ele esta a ligar-se bem. Apenas se liga a 10 nodes de cada vez, certo?
