As you may know, YieldWallet has been running a Cardano stake pool on the Shelley incentivized testnet since late January. We’ve learnt a lot along the way, solidified the Technical infrastructure, Hardware and Software running our stake pool. We’re also participating in various community initiatives to benefit our fellow Stake pool operators and the Cardano network as a whole. We thought now would be a good checkpoint to provide the community with an update.

The Hardware

Based on extensive testing and monitoring of our staking pool we settled on a memory optimized node

r5.large AWS instance

2 vCPUs

16 GB RAM

SSD storage

Technical architecture / Software

Each node has 2 Jormungandr instances running with their own Block storage. We’ve put in place a Node.js based process control system to

a. monitor both nodes and ensure uptime

b. ensure that only one of them is leader

c. swap leaders if one of them is ahead in terms of syncing blocks

d. keep us updated on leader logs i.e. opportunities to mint blocks via a Telegram bot interface

The infrastructure also ensures it deals with cases such as a node’s failure to complete the process of bootstrapping its blockchain storage as well as scenarios where both nodes fall way behind (or ‘drift’ too far from the current block being produced).

This has pretty much given us a hands-off reliable node setup and should instill confidence in Cardano testnet delegators to support us to mint blocks and earn testnet ADA, which will be converted in some form into real ADA at the end of the Incentivized testnet period.

Cardano Stakepool Bootstrap initiative

Yieldwallet is also a part of the Cardano Stakepool Bootstrap initiative. It’s quite difficult for smaller staking pools (such as ourselves) to have enough staked to guarantee block creation rights every epoch (9 Million ADA required as of this writing).

A few good Samaritans of the Cardano community created this group as a way for several small pools to focus on delegating all their stake to one pool for a period of 2 epochs, in rotation. That way every pool in turn gets a chance to make some blocks, which of course is the most gratifying thing to see for someone running a pool on testnet. More info on this can be found here: https://www.adafrog.io/bootstrap.php

Note: It’s come to our attention that there may be some misunderstanding around our name. To clarify: We are a staking pool. We are not currently a Cardano wallet and we have no downloadable software or browser plugins. Stake to us through Daedalus or Yoroi. Anyone claiming to offer ‘YieldWallet’ software is a scammer. Be safe out there people!

What is YieldWallet.io?

YieldWallet is a staking-as-a-service platform based out of India. Our goal is to help holders of various PoS (Proof-of-stake) and dPos (delegate Proof-of-stake) tokens participate to secure or power their networks and earn a yield on their tokens, regardless of their level of technical sophistication and investment level.

We run a service that is highly reliable, available and secure. We also are committed to only supporting those coins or tokens whose project and team we believe in. Cardano is one of those few high-quality projects in the space that we would like to support.

Why delegate to Yieldwallet.io?

ADA testnet holders will have the option of selecting from many stake pools. Here’s why you should consider supporting YieldWallet.io.

a. Our performance running services for Livepeer, Tezos and Decred can be seen at their respective links. We have established a track record in the staking space. While we aren’t the largest service out there, we’re certainly in the top in terms of availability and uptime.

b. We’re building a Cryptocurrency Exchange that will not only feature Cardano trading pairs against other Major Cryptocurrencies, but also ADA/INR (Indian rupee) pairs.

c. We offer 24 / 7 customer support and are always available to answer any questions you have or help you with the staking process.

d. We will continue to support the Cardano community in any way we can, such as participating in initiatives such as the Stakepool Bootstrap initiative described above.

Delegate to us. Would really need and appreciate your support. Ticker symbol: YIELD
