Lava Network. Sõlme paigaldamine

Lava on esimene plokiahela juurdepääsu moodulvõrk, mis tutvustab uut lähenemisviisi: "spetsifikatsioonid" on primitiiv, mis võimaldab osalejatel lisada alusprotokollile uute ahelate ja andmeteenuste toetust ilma lubadusteta. RPC on võrgu esimene toetatud teenus. Arendajad integreerivad Lava oma projektidesse andmete saamiseks ja võrgusõlmede operaatorid on motiveeritud reageerima kiiresti, täpselt ja usaldusväärselt. Lava loob kiire, skaleeritava ja ühtse võrgu, mis võimaldab juurdepääsu mitmevõrgulisele maailmale.

Lava testvõrgu paigaldusjuhend

Minimaalsed nõuded riistvarale:

Käsitsi paigaldamine

serveri ettevalmistamine

sudo apt update && sudo apt upgrade -y
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc git jq chrony liblz4-tool -y

GO 1.21.6 paigaldamine

ver="1.21.6"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Build 19.08.24

cd $HOME && mkdir $HOME/go/bin/
