 The architecture of TON is built in such a way that a lot of chains can exist simultaneously and independently in it - they can be both private or public.
 Nodes have the ability to choose which shards and chains they store and process.
 At the same time, the communication protocol remains unchanged due to its universality. Protocols such as DHT, RLDP and Overlays allow this to be achieved.

+
+In contrast to ADNL, the TON overlay networks usually do not support
+sending datagrams to other arbitrary nodes. Instead, some “semi-permanent
+links” are established between certain nodes (called “neighbors” with respect to

+# Overview: Sharding and Split Merge in the TON Blockchain
+
+[//]: # (TODO, this is from gpt)
+
+The TON Blockchain employs advanced sharding mechanisms to enhance scalability and performance, allowing it to efficiently process a massive number of transactions. 
+The core concept is splitting the blockchain into smaller, independent pieces called **shards**. These shards can handle transactions in parallel, ensuring high throughput even as the network grows.
+
+In TON, sharding is highly dynamic. Unlike other blockchains, which have a fixed number of shards, TON can create new shards on demand. 
+As the transaction load increases, shards split, and as the load decreases, they merge. 
+This flexibility ensures that the system can adapt to varying workloads while maintaining efficiency.
+
+The **Masterchain** plays a crucial role, maintaining the network configuration and the final state of all **workchains** and **shardchains**. 
+While the masterchain is responsible for overall coordination, **workchains** operate under their specific rules, each of which can be split further into shardchains. 
+Currently, only one workchain (the **Basechain**) operates on TON.
+
+At the heart of TON's efficiency is the **Infinity Sharding Paradigm**, which treats each account as part of its own "accountchain."
+These accountchains are then aggregated into shardchain blocks, facilitating efficient transaction processing.
+
+In addition to the dynamic creation of shards, TON uses **Split Merge** functionality, which allows the network to efficiently respond to changing transaction loads. This system enhances scalability and interaction within the blockchain network, exemplifying TON's approach to resolving common blockchain challenges with a focus on efficiency and global consistency.

+# Smart Contract Addresses
+
+[//]: # (TODO, this is gpt)
+
+On the TON Blockchain, every actor, including wallets and smart contracts, is represented by an address. These addresses are critical for receiving and sending messages and transactions. There are two main formats for smart contract addresses: **raw addresses** and **user-friendly addresses**.
+
+## Address Components
+
+Each address on TON consists of two main components:
+- **Workchain ID**: A signed 32-bit integer that denotes which workchain the contract belongs to (e.g., `-1` for the Masterchain and `0` for the Basechain).
+- **Account ID**: A unique identifier for the contract, generally 256 bits in length for the Masterchain and Basechain.
+
+## Raw vs. User-Friendly Addresses
+
+### Raw Address
+A **raw address** contains only the basic elements:
+- **Workchain ID** (e.g., `-1` for Masterchain)
+- **Account ID**: A 256-bit unique identifier
+
+Example:  
+`-1:fcb91a3a3816d0f7b8c2c76108b8a9bc5a6b7a55bd79f8ab101c52db29232260`
+
+However, raw addresses have two main issues:
+1. They lack built-in error checking, meaning a mistake in copying can lead to loss of funds.
+2. They do not support additional features like bounceable/non-bounceable flags.
+
+### User-Friendly Address
+
+A **user-friendly address** solves these problems by incorporating:
+1. **Flags**: Indicates if the address is bounceable (for contracts) or non-bounceable (for wallets).
+2. **Checksum**: A 2-byte error-checking mechanism (CRC16) that helps detect errors before sending.
+3. **Encoding**: Transforms the raw address into a readable, compact form using base64 or base64url.
+
+For example, the same raw address can be converted into a user-friendly address like:  
+`kf/8uRo6OBbQ97jCx2EIuKm8Wmt6Vb15+KsQHFLbKSMiYIny` (base64)
+
+User-friendly addresses make transactions safer by preventing errors and allowing the return of funds in case of failed transactions.
+
+## Address States
+
+Each address on TON can be in one of the following states:
+- **Nonexist**: The address has no data (initial state for all addresses).
+- **Uninit**: The address has a balance but no smart contract code.
+- **Active**: The address is live with smart contract code and balance.
+- **Frozen**: The address is locked due to storage costs exceeding its balance.
+
+## Converting Between Address Formats
+
+To convert between raw and user-friendly addresses, you can use TON APIs or developer tools like [ton.org/address](https://ton.org/address). These utilities allow seamless conversion and ensure proper formatting before sending transactions.
+
+For more details on how to handle these addresses, including encoding examples and transaction security, you can refer to the full guide in [Addresses Documentation](/learn/overviews/addresses).
