Now before we take a look at lightweight Bitcoin wallets or SPV wallets let’s see what light weight / SPV clients are and the advantages they offer in comparison with core wallet.
What are SPV wallets? Bitcoin light wallets
Lightweight Bitcoin wallet is sometimes referred to as SPV wallet or SPV client. SPV means Simplified Payment Verification which speed up the verification process lot faster. To understand SPV wallets you first need to know how core wallet works.
Bitcoin blockchain is just a linear series of blocks. Each block in a blockchain mainly includes
- Block header (contains reference to previous block hash) and
- Transactions (A list of all transactions included in the block).
To verify a particular transaction the client needs to scan all the preceding incoming / outgoing transactions to and from the particular senders address. To do so the wallet has to download the entire blockchain to your local machine. This is what core wallet does.
Problem with core wallet
The biggest problem with Bitcoin core wallet is storage space and bandwidth requirements. It downloads and stores the entire blockchain to your device. Currently to setup and run core wallet you’ll need around 330+ GB of disk storage space (https://www.blockchain.com/charts/blocks-size). Also as the Bitcoin blockchain grows overtime the storage space requirements also becomes too large.
Other than high internet bandwidth and disk storage requirements the official Bitcoin core wallet is also slow. Especially fresh install takes a lot of time (even days) depending on your internet speed. Until it has completely sync up with the blockchain you cannot initiate any transaction.
Even if you’ve already setup the core wallet and used it before it will still take significant amount of time to catch up with the blockchain, later when you are opening the wallet.
This can get quite inconvenient at times and to tackle this issue SPV wallets are designed.
Lightweight Bitcoin Wallets
What makes a Bitcoin light wallet light? In simple there is no need for downloading the entire blockchain to your computer. Light Wallets works by connecting to a server that runs a fully synchronized node.
Lightweight wallet or Simplified Payment Verification (SPV) wallet is a client that is typically in contrast to running a full node client. The main difference is that they do not download the complete blockchain hence saving bandwidth and storage space.
A light wallet or light note instead only downloads the block headers to validate the authenticity of the transactions.
Since Bitcoin light wallets doesn’t store blockchain on your computer they only rely on a trusted server to send and receive transactions.
- These wallets are faster, lighter, easy to maintain and run. They save you sync time and significant amount of storage space.
- They offer same security as QT clients and other popular desktop wallets. Private keys are stored on your device and only you control it.
- Most light wallets are cross compatible and they work well in all environments such as Desktop, Mobile or even from a pen drive. Moreover they are easy to backup and replace as most wallets uses BIP39 standard.
- Light nodes has some privacy issues since they completely rely on third party operated full nodes.
- They are not as secure as Bitcoin core when it comes to payment verification as light wallets use Simplified Payment Verification (SPV) to verify transactions.

So to operate; these wallets effectively depend on full nodes that are run by a trusted party. Is it safe to connect wallet to a certain full node servers?
Are SPV clients safe?
SPV wallets are not new. They’ve been around since the early days of Bitcoin and it is even described in section 8 of Satoshi Nakamoto’s original white paper (https://coinguides.org/bitcoin.pdf).
Lightweight client existed right from the beginning and they are a perfectly fine way to operate a wallet. One good example is Electrum Bitcoin wallet which saves the user the hassle of running a full node.
These wallets are safe and does not affect your security in any way. Your Bitcoin private keys are stored locally on your device.
Thin wallets are way better than storing coins on exchange and some web wallets. Moreover it makes sure your transactions are in a block and it provides confirmation.
For sending storing and receiving; Bitcoin light wallets are more than enough.

Consider Hardware Wallets

These wallets are a great option for anyone looking to send frequent Bitcoin payments from their computer or mobile. But other than transacting if you are looking to hodl your Bitcoin long term then consider buying a hardware wallet.
Please note that all the Bitcoin wallets listed above are classified as hot wallets. Meaning these wallets are connected to the Internet most of the times. Hot wallets are prone to attacks and so they are considered less secure.
If you are planning to hold large amounts of Bitcoin then they should not be stored on your computer or mobile wallets. Instead use a cold storage. Hardware wallet provides the most secure storage solution for your Bitcoin. However they come at a cost.
We recommend Ledger Nano X or Trezor Model T – Two most popular and secure Bitcoin wallet that you can get Today.
Bitcoin core – Also consider this
Bitcoin light wallets provides ease of use. For just sending & receiving Bitcoin you don’t need to run a full node.
But you also need to understand that full node is what forms the back bone of the Bitcoin network. Without full nodes there would not be a Bitcoin network.
If you are a Bitcoin enthusiast and want to support the Bitcoin network then consider running Bitcoin core.
Bitcoin core is a full node Bitcoin wallet. It is more secure, offers completely control and is one of the most private Bitcoin wallet. However the downside as we discussed earlier is that it downloads the entire blockchain to your PC. So it takes some patience and time to setup and operate.
Anyways if you do not have huge HDD / SSD space left and if disk-space is your main concern then you can consider pruning the blockchain. It won’t affect the security, privacy of your core wallet and additionally the file size never exceeds 5 GB. Moreover sync time is not as bad as old core wallets especially if you have SSD.
So that’s all!
If you are looking for small wallet that doesn’t require installation then use the standalone, lightweight bitcoin wallet mentioned in this article. For long term secure storage use hardware wallets.
Always do your own research before downloading and installing a Bitcoin wallet.
These are the rundown of the best Bitcoin light wallets out there which is lightweight, easy to set up, simple to use and easy to backup / recover using wallet seed.
