# Demo of Cross chain transfer [Peerplays TESTNET -- Hive MAINNET]

## Objective

Demonstrate Peerplays's SONs technology integrated to work with Hive Blockchain. The Sidechain Operator Nodes (SON) is a decentralized, oracle system operated by elected nodes on the Peerplays blockchain. In this scenario, we are demonstrating Hive-SONs the implementation specific for the Hive blockchain. This is the first of multiple features for Hive blockchain integrations that we are working on along with SPK Network.

### Overview

A TESTNET of Peerplays comprising of witness nodes and SONs will be created. This network will be called as #YMIR and will comprise of Peerplays's current `son-for-hive` branch running in a single server using dockers.

Procedure :

- #YMIR will be configured and brought up by Peerplays developers
- Few test transactions will be performed using HIVE and HBD to ensure the performance of the integration
- If the first few tests works fine, the network will be left alone for 3 days
- Upon completion of the 3 days, the connection details for others to join the network will be shared
- The network will be made available and open for 15 days for others to join and test
- We welcome feedback and also poke at the multi-signature wallet created on the Hive blockchain

**Detailed Procedure**

- Setup a Peerplays testnet (using docker) with Hive SONs & Bitcoin SONs
- We should be using 7 Sidechain Operator Nodes for simplicity
- Create SON multi-signature wallet account, say: `son\_account` on the Hive blockchain's MAINNET (note, mainnet and not the testnet.)
- On the Peerplays TESTNET the SON accounts should be: `son1-ppy`, `son2-ppy`, `son3-ppy`, `son4-ppy`, `son5-ppy`,`son6-ppy`,`son7-ppy`
- On the Hive MAINNET the SON accounts should be: `son1-hive,`son2-hive`,` son3-hive`,` son4-hive`,`son5-hive`,` son6-hive`,` son7-hive\`
- Make sure that `son\_account` account has enough funds and Resource Credits to perform transaction
- Send HIVE from account `bobinson` on Hive blockchain to `spk-ppy` on the testnet created earlier (deposit)
- Withdraw pHIVE from `spk\_ppy` to `bobinson`

### Needs help with the following

- Inspect the settings of the SON accounts on the Hive blockchain (`son1-hive` to `son7-hive`)
- Review the multisignature wallet creation (`[son-account](https://hiveblocks.com/@son-account)`)

### SON accounts

There are 7 accounts as of now and they are `son1-hive` .. `son7-hive`. For now they are created and no changes are made to Recovery accounts, withdraw routes or keys are default.

### Multi-signature Wallet

Hive blockchian supports creation of multisignature wallets. Due to the fact that Hive has unique human readable addresses, they are always mapped with an address.

A multi signature wallet is created during the initialization of the sidechain network. In simple terms, there are 7 Hive Blockchain accounts who collectively create a wallet where the funds are locked during the cross chain transfer.

All 7 accounts needs to authorize the movements on funds and this is handled programmatically.

Behind the screens an equivalent of the following set of commands is used to create the weighted multi-signature wallet.

## Connecting to YMIR via cli\_wallet

At this stage, only connecting and checking stats is provided on purpose. A UI to create to accounts will be provided in the coming days so that anyone can test the transactions.

**Getting the prebuild **`**cli\_wallet**`:

On a Ubuntu GNU/Linux box:

In general, get the latest from https://gitlab.com/PBSA/peerplays/-/pipelines

Connecting to YMIR

sample cli\_wallet commands:

`set\_password a-super-secret-password` `unlock a-super-secret-password` `list\_account\_balances spk-ppy` `list\_active\_sons` `list\_accounts s 10` #lists 10 accounts with letter s in the account name

# Example transfers

## DEPOSIT: sending funds to Peerplays TESTNET (YMIR) from Hive MAINET

Account on Peerplays (TESTNET), `spk-ppy` has the following balance at first:

The cross chain withdrawal, aka sending of HIVE/HBD to a Peerplays account can be done as follows


In the above

- A Hive account `bobinson` is sending 0.001 HIVE to a Peerplays TESTNET account called `spk-ppy`
- To achieve the same, simply send funds to `son-account` on Hive with the receipient account name as memo

Once the above transaction is done, the account balance of `spk-account` can be checked again

HBD transfer to Peerplays


## WITHDRAW: sending funds to Hive MAINET from PEERPLAYS TESTNET (YMIR)

Thats it !
