Simple payment verification without running a full node is a fundamental need in any payment system. Satoshi knew it and hence we have this excerpt from the Bitcoin whitepaper.
They're the first stage of light clients. Solana will soon have it 💯

2. diet clients - 1/N assumptions for safety. Votes should sign a merkle root for turbine shreds, clients can sample a bunch of nodes for shreds and confirm that honest nodes aren't eclipsed and computed the same bankhash. Prevents corrupt majority attacks!

Although fraud proofs would require a state root for every block something that
@aeyakovenko
and
@solanalabs
have in their roadmap.
This was a very high level explanation of how tinydancer works and we will soon be releasing a more in-depth whitepaper for all the comp sci nerds.

We believe there's a large opportunity to create a parallel DA layer for Solana starting with out light client.
What this means is that we can have a per block state root in solana & validators can be incentivized to produce it without affecting block times

Now at a high level, Solana blockchain has the following network participants:
• A validator node: Responsible for consensus and security of the chain. One of which becomes a block producer and processes transactions, called a Leader Node.

Tinydancer would also connect to it's own network of light clients using p2p communications to create it's own DA plane.
This would enable features such as:
- Private Repair Network
- On-Demand Verification

You're in a hurry and this Monke is very important for you. You pick your favourite one and place a buy order.
Your transaction succeeds and the funds are deducted from your wallet. But here's a catch...

• Full node - Nodes that don't participate in consensus but do verify the state of the chain and serve on chain data to clients/users.
• Clients: This could be any app/website consuming on-chain data for their functionality like wallets, payment apps, DEXs etc

The Private Repair Network:
It would help full nodes and validators repair their blocks significantly faster with the help of the Tinydancer DA plane.
Traditional repair is very slow and hence having faster repair would be a massive improvement for validators.

Imagine you want to buy an NFT from your favourite collection on

Monke.
You open your favourite hot wallet and connect it to the website.

We achieve this by Data Availability or DA sampling. Let's take an example:
Assume there are 100 nodes, out of which 99 are corrupt and only of them is honest. If the honest node receives the block and verifies that it is invalid or fraudulent then the user can be notified.
1
0
18
But if corrupt nodes don't send the block to the honest node and essentially eclipse it from the network then the user will never know.
This is where the light client uses DA sampling to ensure the block data is always available to everyone in the network.

In your case it might've been that one of the RPC provider was a part of a corrupt Supermajority and they were colluding against your particular transaction(we're looking at you
@colludingnode
).
They approved a fraud txn and finalized the block containing that transaction.

How can someone verify the state of their particular transaction without having to go down the trouble of setting up a node.
This is a fundamental security issue that needs to be addressed since majority of the normal users can't afford to run a full node.

You don't see the Monke in your wallet. It just isn't there!
You panic and go to several discords asking for help. They ask you to switch your RPC provider but you don't know what that is....

So how do you protect against such corrupt supermajority attacks?
Enter Tinydancer - Solana's first light client implementation.
If you're running the client, you can ask any full node - "what's the status of this txn? Can you tell me if it was included in a valid block?"

You can find detailed documentation at with steps on how to run it locally!

We're also experimenting to do this with snapshots too so when a validator restarts they can get up and running much faster.
1

15
Now for any transaction like yours to be confirmed and finalized,
the network should reach a consensus on your particular transaction.
Specifically, 2/3 of the consensus participating nodes (called Supermajority) should agree that your transaction is valid and approved.
1
0
14
You finally decide to check the explorer and the explorer shows you that the transaction was successful and there is a Monke in your wallet.
Now you wonder who's lying to you, is it your precious wallet or is it the explorer? 🤔

This is a tough situation, you have no idea what to do other than sit back disappointed and mourn the loss of your funds.
Clearly a fraud has occurred but you don't know who to trust and who not to 🤷♂️
1

15
Moving on to On-Demand Verification:
This will be a service similar to the solana-ledger-tool that allows users to pay validators verify a slot in the snapshot.
A user can pay and query N validators and if M/N validators respond with a valid response then user can accept that.
1

Now in case the one honest nodes finds an invalid block, it can produce a fraud proof and send it to the light client.
With this the client doesn't have to trust the honest node, it can just verify the cryptographic proof and check if the block is fraudulent or not.

❓ Why is this needed?
Currently, there's no way to verify that a transaction has been included in a particular block.
Ideally, we want to be able to verify this locally, on any user's device, like a smartphone for instance.

“A blockchain doesn’t serve its purpose if it’s users are trusting intermediaries to use it.”
Say no more.
You can’t say “my chain scales and yours doesn’t” until it has working trust-minimized light clients.
It’s like saying “my car goes faster than yours” when neither car can even start.
A blockchain doesn’t serve its purpose if it’s users are trusting intermediaries to use it.

First, what is a light client?
A cluster participant that does not itself run a full node ( validator, RPC node ) but has trust minimized access to the network without large hardware requirements.
Your solana transactions might be in danger and you can’t do anything about it. Until now.

To address these issues we proposed a change in the calculation of blockhash to:
- Construct a merkle tree of entries instead of a hash
- Include the txn status in the merkle tree of the batch of transactions that are part of the entry.

If you're interested in how these changes are used in the light client, you can refer to this diagram alongside the detailed design section in the SIMD.

Additionally, we want to thank
@m_schneider
for his suggestion to include txn logs in the Merkle which will also be part of the SIMD soon.

In conjunction to these changes we proposed a new RPC method to get proofs of transaction inclusion. These proofs are used to compute to the root i.e. the bankhash, locally.

For the v0 of our client, we're focusing on a simple payment verification (SPV) client that verifies
- A particular transaction of interest has been included in a block
- The block has been voted on by a trusted set of validators based off this proposal

Each slot is identified by a bankhash containing:
- Parent hash: bank hash of the parent block.
- Accounts delta hash: hash of all modified accounts
- Signature count: Number of signatures processed in this block
- Recent blockhash: Last PoH hash in this block

1. Verifying txn inclusion would require all the entries to be hashed again which is more computationally intensive.
2. We cannot verify if a transaction is successful even if it is included as statuses are not part of the blockhash

Our SIMD proposes 2 main changes for txn verification:
1. Adding a new RPC method which provides a proof that a txn has been included in a slot.
2. Modifying the blockhash to be computed as a merkle tree of entries and include txn statuses.
1
0
3
The first change would be complementary to the second one.
The RPC method would provide us with a proof that can be verified locally on the client side without any overhead.
The second change requires understanding a few solana internals.
