Tezos Logo

I followed the Documentation from Tezos that you can find here:

https://tezos.gitlab.io/alphanet/index.html

The environment I used

I am using VirtualBox with Debian:

Configuration:

  • OS type : Linux - Debian 64 Bit
  • Disk type : VDI 700 Go (dynamic)
  • Memory : 4 Go
  • Video memory: 32 Mo
  • CD Rom: debian-testing-amd64-netinst.iso

Result:

Tezos VM Specs

Note:

If you need to extend the VDI Size (Windows):

> "D:\Program Files\Oracle\VirtualBox\VBoxManage.exe" modifyhd "D:\Users\Chain Accelerator\VirtualBox VMs\tezos\tezos.vdi" --resize 700000

My Debian testing (buster)

  • Default Debian interface
  • No other requirement

Now that we are done setting up our environment let’s start using Tezos!

Working with Tezos

Lien vers le gist :

Get Tezos

We will be using Tezos’ test network: Alphanet.

chainacc@tezos:~$ wget https://github.com/ocaml/opam/releases/download/2.0.1/opam-2.0.1-x86_64-linuxchainacc@tezos:~$ sudo cp opam-2.0.1-x86_64-linux /usr/local/bin/opamchainacc@tezos:~$ sudo chmod a+x /usr/local/bin/opamchainacc@tezos:~$ git clone https://gitlab.com/tezos/tezos.gitchainacc@tezos:~$ cd tezoschainacc@tezos:~$ git checkout alphanetchainacc@tezos:~$ opam init --barechainacc@tezos:~$ make build-depschainacc@tezos:~$ eval $(opam env)chainacc@tezos:~$ makechainacc@tezos:~$ export PATH=~/tezos:$PATHchainacc@tezos:~$ source ./src/bin_client/bash-completion.shchainacc@tezos:~$ export TEZOS_CLIENT_UNSAFE_DISABLE_DISCLAIMER=Y

Use Tezos

To make sure everything went okay, please check that all of the following binaries are available:

  • tezos-node: the tezos daemon itself;
  • tezos-client: a command-line client and basic wallet;
  • tezos-admin-client: administration tool for the node;
  • tezos-{baker,endorser,accuser}-alpha: daemons to bake, endorse and accuse on the Tezos network;
  • tezos-signer: a client to remotely sign operations or blocks;

(Directly from https://tezos.gitlab.io/alphanet/introduction/howtouse.html)

Generate your Node Identity:

chainacc@tezos:~$ ./tezos-node identity generate

/!\ It may take several minutes.

You can now run your node with the following command:

chainacc@tezos:~$ ./tezos-node run --rpc-addr 127.0.0.1

BE CAREFUL. It takes time to actually sync the node. Avoid using a HDD and rather use a SSD instead.

To know if your node synced, simply do the following command and see if the dates match or are very close. If not, it means that your node is not done syncing yet.

chainacc@tezos:~$ ./tezos-client get timestamp && date -u -Isec

Run Tezos (Use Case)

Bob wants to delegate some coins to Alice, a Baker.

  • Creating Alice and Bob wallets

Let’s go to Alphanet Faucet here: https://faucet.tzalpha.net/ and grab some Tezos. Once you have the .JSON file (preserve it), simply create Alice account:

./tezos-client activate account Alice with FILE_HERE.JSON

(Replace FILE_HERE.JSON with your file.json from the faucet)

Got ꜩ 10448.944029 for Alice.

Warning:

  • Running a delegate

We just need a little more Tez to cover security deposits and such, so to avoid missing funds, we’ll just create another account from the faucet and transfer the tez to Alice.

./tezos-client activate account ChainAcc with FILE_HERE.JSON

And then:

./tezos-client transfer 9000 from ChainAcc to Alice --fee 1

Let’s check Alice’s new balance:

./tezos-client get balance for Alice

And we get 19448.944029 ꜩ (you need at least ONE roll to bake, 1 roll being 10k ꜩ).

We can now run a delegate.

./tezos-client register key Alice as delegate

Alice is now a delegate. We can now start baking. Please note that the part in bold can be different for you.

./tezos-baker-003-PsddFKi3 run with local node ~/.tezos-node Alice

Waiting for the node to be synchronized with its peers...
Node synchronized.
Baker started.

Now Bob wants to delegate to Alice, here is how:

./tezos-client originate account bob_del for Bob transferring 250 from Bob --delegate Alice

Error here:

Node is bootstrapped, ready for injecting operations.
Fatal error:
  The operation will burn ꜩ0.257 which is higher than the configured burn cap (ꜩ0).
   Use `--burn-cap 0.257` to emit this operation.

To fix this, we just follow the instructions:

./tezos-client originate account bob_del for Bob transferring 250 from Bob --delegate Alice --burn-cap 0.257

Aaaaand it works!

If we go on https://alphanet.tzscan.io/ and check for Alice’s account, we see this:

Alice’s Balance

Alice has a balance of ꜩ 19 448 but her staking balance has ꜩ 250 more (these were delegated by Bob).
