SORA is a new economic system aimed at creating a supranational, world economic system with built-in tools for decentralized finance (DeFi). The SORA network implements a new way of parachain architecture on Polkadot and Kusama network, with the capability to bridge external blockchains (like Ethereum) to the Polkadot ecosystem.

This is FRAME-based Substrate node of SORA2. This repo contains code of node, pallets, runtime.
For Kusama:
make kusamaFor Polkadot:
make polkadotFor Rococo:
make rococoFor Kusama:
make test-kusamaFor Polkadot:
make test-polkadotFor Rococo:
make test-rococoSince project can only be compiled with features it would be convenient to set feature in rust analyzer
.vscode/settings.json may look like
{
"rust-analyzer.cargo.features": [
"rococo"
]

Now we have this implementation:
sora2-parachain/runtime/src/lib.rs
Line 704 in 3a8f54f
But it can cause problems with asset transfer when an account does not have balance on parachain
The outbound channel requires balances on account whom assets are transferred, otherwise assets could not be sended to mainnet through the bridge

We want to determine the set of metrics to monitor the health of the parachain.
We want to communicate with the DevOps team to determine a set of metrics to monitor the health of the parachain(s).
We have a Telegram group with other participants of the Dotsama ecosystem to define a set of metrics for solo chains, relay chains, and parachains. We can use this chat to help defining the set of metrics.

There are two cases when extending our parachain slot:
With overlapping slot
Without overlapping slot
If we apply for slots that don't overlap, then we can bid with the same paraId.

Ongoing Kusama Auction: No ongoing auction (although according to Kusama Auction it should be the 64th (ends in ~1.5 day, at block 15651000))
Kusama auction 65th should start in ~6 days (at block 15724800)
Kusama auction winners for auctions 64th to 67th will be onboarded for lease periods #26 - #33
Ongoing Polkadot Auction: 34th (10/12). Next one (35th): 16/12 - 22/12
1 lease period = 6 weeks

Aha! Link: https://soramitsucoltd.aha.io/features/SKP-8
Our parachain on Rococo stopped producing blocks. We need to investigate the reason why and fix it.
We need our parachain to produce blocks to be able to communicate with the Kusama ecosystem on Rococo (testnet).
According to the DevOps team, the reason is that our collator stopped producing blocks.

Additional context

The problem exists on SORA - if transaction fails the refund would not be sended to sender to parachains/relaychain

We have a Kusama parachain producing blocks and connected to the Kusama ecosystem. We want people to be able to see that we are part of the ecosystem.
For that reason, we need to investigate on which websites we should be referenced so that users could easily find us.
Start with Rococo
Once we validated functionality on Rococo, repeat on Kusama parachain

Since our parachain does not have tokens we should ensure that there is no access to xcm executor directly through extrinsics

Current Lease Period: 26/06/2022 15:13 ~ 26/01/2023 11:37
Previous crowdloan: https://kusama.subscan.io/parachain/2011?tab=crowdloan
From https://kusama.network/auctions/:
"After the lease is over, the slot will go up for auction again and the team will need to bid again if they wish to retain a slot"
"Each auction allocates a parachain slot for a total deployment period of 48 weeks. Teams are not required to bid for the full 48-week period, but can specify a contiguous range from 6 weeks to 48 weeks. This means that two or more teams may win one particular slot auction if they each bid on different, non-overlapping lease periods within the full 48-week deployment period. For example, one team may bid on the first 24 weeks, and another team could bid on the second 24 weeks. The winner selection algorithm is designed to maximize the amount of KSM held over the entire 48-week period, and will pick the best combination of non-overlapping bids to achieve that objective."
There are two cases when extending our parachain slot:
With overlapping slot
Without overlapping slot
If we apply for slots that don't overlap, then we can bid with the same paraId.
